A built-in type for strings. This is the built-in string Variant type (and the one used by GDScript). Strings may contain any number of Unicode characters, and expose methods useful for manipulating and generating strings. Strings are reference-counted and use a copy-on-write approach (every modification to a string returns a new [String]), so passing them around is cheap in resources. Some string methods have corresponding variations. Variations suffixed with [code]n[/code] ([method countn], [method findn], [method replacen], etc.) are [b]case-insensitive[/b] (they make no distinction between uppercase and lowercase letters). Method variations prefixed with [code]r[/code] ([method rfind], [method rsplit], etc.) are reversed, and start from the end of the string, instead of the beginning. [b]Note:[/b] In a boolean context, a string will evaluate to [code]false[/code] if it is empty ([code]""[/code]). Otherwise, a string will always evaluate to [code]true[/code]. $DOCS_URL/tutorials/scripting/gdscript/gdscript_format_string.html Constructs an empty [String] ([code]""[/code]). Constructs a [String] as a copy of the given [String]. Constructs a new [String] from the given [NodePath]. Constructs a new [String] from the given [StringName]. Returns [code]true[/code] if the string begins with the given [param text]. See also [method ends_with]. Returns an array containing the bigrams (pairs of consecutive characters) of this string. [codeblock] print("Get up!".bigrams()) # Prints ["Ge", "et", "t ", " u", "up", "p!"] [/codeblock] Converts the string representing a binary number into an [int]. The string may optionally be prefixed with [code]"0b"[/code], and an additional [code]-[/code] prefix for negative numbers. [codeblocks] [gdscript] print("101".bin_to_int()) # Prints 5 print("0b101".bin_to_int()) # Prints 5 print("-0b10".bin_to_int()) # Prints -2 [/gdscript] [csharp] GD.Print("101".BinToInt()); // Prints 5 GD.Print("0b101".BinToInt()); // Prints 5 GD.Print("-0b10".BinToInt()); // Prints -2 [/csharp] [/codeblocks] Returns a copy of the string with special characters escaped using the C language standard. Returns a copy of the string with escaped characters replaced by their meanings. Supported escape sequences are [code]\'[/code], [code]\"[/code], [code]\\[/code], [code]\a[/code], [code]\b[/code], [code]\f[/code], [code]\n[/code], [code]\r[/code], [code]\t[/code], [code]\v[/code]. [b]Note:[/b] Unlike the GDScript parser, this method doesn't support the [code]\uXXXX[/code] escape sequence. Changes the appearance of the string: replaces underscores ([code]_[/code]) with spaces, adds spaces before uppercase letters in the middle of a word, converts all letters to lowercase, then converts the first one and each one following a space to uppercase. [codeblocks] [gdscript] "move_local_x".capitalize() # Returns "Move Local X" "sceneFile_path".capitalize() # Returns "Scene File Path" [/gdscript] [csharp] "move_local_x".Capitalize(); // Returns "Move Local X" "sceneFile_path".Capitalize(); // Returns "Scene File Path" [/csharp] [/codeblocks] [b]Note:[/b] This method not the same as the default appearance of properties in the Inspector dock, as it does not capitalize acronyms ([code]"2D"[/code], [code]"FPS"[/code], [code]"PNG"[/code], etc.) as you may expect. Performs a case-sensitive comparison to another string. Returns [code]-1[/code] if less than, [code]1[/code] if greater than, or [code]0[/code] if equal. "Less than" and "greater than" are determined by the [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode code points[/url] of each string, which roughly matches the alphabetical order. With different string lengths, returns [code]1[/code] if this string is longer than the [param to] string, or [code]-1[/code] if shorter. Note that the length of empty strings is [i]always[/i] [code]0[/code]. To get a [bool] result from a string comparison, use the [code]==[/code] operator instead. See also [method nocasecmp_to], [method naturalcasecmp_to], and [method naturalnocasecmp_to]. Returns a single Unicode character from the decimal [param char]. You may use [url=https://unicodelookup.com/]unicodelookup.com[/url] or [url=https://www.unicode.org/charts/]unicode.org[/url] as points of reference. [codeblock] print(String.chr(65)) # Prints "A" print(String.chr(129302)) # Prints "🤖" (robot face emoji) [/codeblock] Returns [code]true[/code] if the string contains [param what]. In GDScript, this corresponds to the [code]in[/code] operator. [codeblocks] [gdscript] print("Node".contains("de")) # Prints true print("team".contains("I")) # Prints false print("I" in "team") # Prints false [/gdscript] [csharp] GD.Print("Node".Contains("de")); // Prints true GD.Print("team".Contains("I")); // Prints false [/csharp] [/codeblocks] If you need to know where [param what] is within the string, use [method find]. Returns the number of occurrences of the substring [param what] between [param from] and [param to] positions. If [param to] is 0, the search continues until the end of the string. Returns the number of occurrences of the substring [param what] between [param from] and [param to] positions, [b]ignoring case[/b]. If [param to] is 0, the search continues until the end of the string. Returns a copy of the string with indentation (leading tabs and spaces) removed. See also [method indent] to add indentation. Returns [code]true[/code] if the string ends with the given [param text]. See also [method begins_with]. Returns a string with [param chars] characters erased starting from [param position]. If [param chars] goes beyond the string's length given the specified [param position], fewer characters will be erased from the returned string. Returns an empty string if either [code]position[/code] or [code]chars[/code] is negative. Returns the original string unmodified if [param chars] is [code]0[/code]. Returns the index of the [b]first[/b] occurrence of [param what] in this string, or [code]-1[/code] if there are none. The search's start can be specified with [param from], continuing to the end of the string. [codeblocks] [gdscript] print("Team".find("I")) # Prints -1 print("Potato".find("t")) # Prints 2 print("Potato".find("t", 3)) # Prints 4 print("Potato".find("t", 5)) # Prints -1 [/gdscript] [csharp] GD.Print("Team".Find("I")); // Prints -1 GD.Print("Potato".Find("t")); // Prints 2 GD.Print("Potato".Find("t", 3)); // Prints 4 GD.Print("Potato".Find("t", 5)); // Prints -1 [/csharp] [/codeblocks] [b]Note:[/b] If you just want to know whether the string contains [param what], use [method contains]. In GDScript, you may also use the [code]in[/code] operator. Returns the index of the [b]first[/b] [b]case-insensitive[/b] occurrence of [param what] in this string, or [code]-1[/code] if there are none. The starting search index can be specified with [param from], continuing to the end of the string. Formats the string by replacing all occurrences of [param placeholder] with the elements of [param values]. [param values] can be a [Dictionary] or an [Array]. Any underscores in [param placeholder] will be replaced with the corresponding keys in advance. Array elements use their index as keys. [codeblock] # Prints "Waiting for Godot is a play by Samuel Beckett, and Godot Engine is named after it." var use_array_values = "Waiting for {0} is a play by {1}, and {0} Engine is named after it." print(use_array_values.format(["Godot", "Samuel Beckett"])) # Prints "User 42 is Godot." print("User {id} is {name}.".format({"id": 42, "name": "Godot"})) [/codeblock] Some additional handling is performed when [param values] is an [Array]. If [param placeholder] does not contain an underscore, the elements of the [param values] array will be used to replace one occurrence of the placeholder in order; If an element of [param values] is another 2-element array, it'll be interpreted as a key-value pair. [codeblock] # Prints "User 42 is Godot." print("User {} is {}.".format([42, "Godot"], "{}")) print("User {id} is {name}.".format([["id", 42], ["name", "Godot"]])) [/codeblock] See also the [url=$DOCS_URL/tutorials/scripting/gdscript/gdscript_format_string.html]GDScript format string[/url] tutorial. [b]Note:[/b] In C#, it's recommended to [url=https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated]interpolate strings with "$"[/url], instead. If the string is a valid file path, returns the base directory name. [codeblock] var dir_path = "/path/to/file.txt".get_base_dir() # dir_path is "/path/to" [/codeblock] If the string is a valid file path, returns the full file path, without the extension. [codeblock] var base = "/path/to/file.txt".get_basename() # base is "/path/to/file" [/codeblock] If the string is a valid file name or path, returns the file extension without the leading period ([code].[/code]). Otherwise, returns an empty string. [codeblock] var a = "/path/to/file.txt".get_extension() # a is "txt" var b = "cool.txt".get_extension() # b is "txt" var c = "cool.font.tres".get_extension() # c is "tres" var d = ".pack1".get_extension() # d is "pack1" var e = "file.txt.".get_extension() # e is "" var f = "file.txt..".get_extension() # f is "" var g = "txt".get_extension() # g is "" var h = "".get_extension() # h is "" [/codeblock] If the string is a valid file path, returns the file name, including the extension. [codeblock] var file = "/path/to/icon.png".get_file() # file is "icon.png" [/codeblock] Splits the string using a [param delimiter] and returns the substring at index [param slice]. Returns an empty string if the [param slice] does not exist. This is faster than [method split], if you only need one substring. [b]Example:[/b] [codeblock] print("i/am/example/hi".get_slice("/", 2)) # Prints "example" [/codeblock] Returns the total number of slices when the string is split with the given [param delimiter] (see [method split]). Splits the string using a Unicode character with code [param delimiter] and returns the substring at index [param slice]. Returns an empty string if the [param slice] does not exist. This is faster than [method split], if you only need one substring. Returns the 32-bit hash value representing the string's contents. [b]Note:[/b] Strings with equal hash values are [i]not[/i] guaranteed to be the same, as a result of hash collisions. On the countrary, strings with different hash values are guaranteed to be different. Decodes a hexadecimal string as a [PackedByteArray]. [codeblocks] [gdscript] var text = "hello world" var encoded = text.to_utf8_buffer().hex_encode() # outputs "68656c6c6f20776f726c64" print(buf.hex_decode().get_string_from_utf8()) [/gdscript] [csharp] var text = "hello world"; var encoded = text.ToUtf8Buffer().HexEncode(); // outputs "68656c6c6f20776f726c64" GD.Print(buf.HexDecode().GetStringFromUtf8()); [/csharp] [/codeblocks] Converts the string representing a hexadecimal number into an [int]. The string may be optionally prefixed with [code]"0x"[/code], and an additional [code]-[/code] prefix for negative numbers. [codeblocks] [gdscript] print("0xff".hex_to_int()) # Prints 255 print("ab".hex_to_int()) # Prints 171 [/gdscript] [csharp] GD.Print("0xff".HexToInt()); // Prints 255 GD.Print("ab".HexToInt()); // Prints 171 [/csharp] [/codeblocks] Converts [param size] which represents a number of bytes into a human-readable form. The result is in [url=https://en.wikipedia.org/wiki/Binary_prefix#IEC_prefixes]IEC prefix format[/url], which may end in either [code]"B"[/code], [code]"KiB"[/code], [code]"MiB"[/code], [code]"GiB"[/code], [code]"TiB"[/code], [code]"PiB"[/code], or [code]"EiB"[/code]. Indents every line of the string with the given [param prefix]. Empty lines are not indented. See also [method dedent] to remove indentation. For example, the string can be indented with two tabulations using [code]"\t\t"[/code], or four spaces using [code]" "[/code]. Inserts [param what] at the given [param position] in the string. Returns [code]true[/code] if the string is a path to a file or directory, and its starting point is explicitly defined. This method is the opposite of [method is_relative_path]. This includes all paths starting with [code]"res://"[/code], [code]"user://"[/code], [code]"C:\"[/code], [code]"/"[/code], etc. Returns [code]true[/code] if the string's length is [code]0[/code] ([code]""[/code]). See also [method length]. Returns [code]true[/code] if the string is a path, and its starting point is dependent on context. The path could begin from the current directory, or the current [Node] (if the string is derived from a [NodePath]), and may sometimes be prefixed with [code]"./"[/code]. This method is the opposite of [method is_absolute_path]. Returns [code]true[/code] if all characters of this string can be found in [param text] in their original order. [codeblock] var text = "Wow, incredible!" print("inedible".is_subsequence_of(text)) # Prints true print("Word!".is_subsequence_of(text)) # Prints true print("Window".is_subsequence_of(text)) # Prints false print("".is_subsequence_of(text)) # Prints true [/codeblock] Returns [code]true[/code] if all characters of this string can be found in [param text] in their original order, [b]ignoring case[/b]. Returns [code]true[/code] if this string does not contain characters that are not allowed in file names ([code]:[/code] [code]/[/code] [code]\[/code] [code]?[/code] [code]*[/code] [code]"[/code] [code]|[/code] [code]%[/code] [code]<[/code] [code]>[/code]). Returns [code]true[/code] if this string represents a valid floating-point number. A valid float may contain only digits, one decimal point ([code].[/code]), and the exponent letter ([code]e[/code]). It may also be prefixed with a positive ([code]+[/code]) or negative ([code]-[/code]) sign. Any valid integer is also a valid float (see [method is_valid_int]). See also [method to_float]. [codeblock] print("1.7".is_valid_float()) # Prints true print("24".is_valid_float()) # Prints true print("7e3".is_valid_float()) # Prints true print("Hello".is_valid_float()) # Prints false [/codeblock] Returns [code]true[/code] if this string is a valid hexadecimal number. A valid hexadecimal number only contains digits or letters [code]A[/code] to [code]F[/code] (either uppercase or lowercase), and may be prefixed with a positive ([code]+[/code]) or negative ([code]-[/code]) sign. If [param with_prefix] is [code]true[/code], the hexadecimal number needs to prefixed by [code]"0x"[/code] to be considered valid. [codeblock] print("A08E".is_valid_hex_number()) # Prints true print("-AbCdEf".is_valid_hex_number()) # Prints true print("2.5".is_valid_hex_number()) # Prints false print("0xDEADC0DE".is_valid_hex_number(true)) # Prints true [/codeblock] Returns [code]true[/code] if this string is a valid color in hexadecimal HTML notation. The string must be a hexadecimal value (see [method is_valid_hex_number]) of either 3, 4, 6 or 8 digits, and may be prefixed by a hash sign ([code]#[/code]). Other HTML notations for colors, such as names or [code]hsl()[/code], are not considered valid. See also [method Color.html]. Returns [code]true[/code] if this string is a valid identifier. A valid identifier may contain only letters, digits and underscores ([code]_[/code]), and the first character may not be a digit. [codeblock] print("node_2d".is_valid_identifier()) # Prints true print("TYPE_FLOAT".is_valid_identifier()) # Prints true print("1st_method".is_valid_identifier()) # Prints false print("MyMethod#2".is_valid_identifier()) # Prints false [/codeblock] Returns [code]true[/code] if this string represents a valid integer. A valid integer only contains digits, and may be prefixed with a positive ([code]+[/code]) or negative ([code]-[/code]) sign. See also [method to_int]. [codeblock] print("7".is_valid_int()) # Prints true print("1.65".is_valid_int()) # Prints false print("Hi".is_valid_int()) # Prints false print("+3".is_valid_int()) # Prints true print("-12".is_valid_int()) # Prints true [/codeblock] Returns [code]true[/code] if this string represents a well-formatted IPv4 or IPv6 address. This method considers [url=https://en.wikipedia.org/wiki/Reserved_IP_addresses]reserved IP addresses[/url] such as [code]"0.0.0.0"[/code] and [code]"ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff"[/code] as valid. Returns the concatenation of [param parts]' elements, with each element separated by the string calling this method. This method is the opposite of [method split]. [b]Example:[/b] [codeblocks] [gdscript] var fruits = ["Apple", "Orange", "Pear", "Kiwi"] print(", ".join(fruits)) # Prints "Apple, Orange, Pear, Kiwi" print("---".join(fruits)) # Prints "Apple---Orange---Pear---Kiwi" [/gdscript] [csharp] var fruits = new string[] {"Apple", "Orange", "Pear", "Kiwi"}; // In C#, this method is static. GD.Print(string.Join(", ", fruits)); // Prints "Apple, Orange, Pear, Kiwi" GD.Print(string.Join("---", fruits)); // Prints "Apple---Orange---Pear---Kiwi" [/csharp] [/codeblocks] Returns a copy of the string with special characters escaped using the JSON standard. Because it closely matches the C standard, it is possible to use [method c_unescape] to unescape the string, if necessary. Returns the first [param length] characters from the beginning of the string. If [param length] is negative, strips the last [param length] characters from the string's end. [codeblock] print("Hello World!".left(3)) # Prints "Hel" print("Hello World!".left(-4)) # Prints "Hello Wo" [/codeblock] Returns the number of characters in the string. Empty strings ([code]""[/code]) always return [code]0[/code]. See also [method is_empty]. Formats the string to be at least [param min_length] long by adding [param character]s to the left of the string, if necessary. See also [method rpad]. Removes a set of characters defined in [param chars] from the string's beginning. See also [method rstrip]. [b]Note:[/b] [param chars] is not a prefix. Use [method trim_prefix] to remove a single prefix, rather than a set of characters. Does a simple expression match (also called "glob" or "globbing"), where [code]*[/code] matches zero or more arbitrary characters and [code]?[/code] matches any single character except a period ([code].[/code]). An empty string or empty expression always evaluates to [code]false[/code]. Does a simple [b]case-insensitive[/b] expression match, where [code]*[/code] matches zero or more arbitrary characters and [code]?[/code] matches any single character except a period ([code].[/code]). An empty string or empty expression always evaluates to [code]false[/code]. Returns the [url=https://en.wikipedia.org/wiki/MD5]MD5 hash[/url] of the string as a [PackedByteArray]. Returns the [url=https://en.wikipedia.org/wiki/MD5]MD5 hash[/url] of the string as another [String]. Performs a [b]case-sensitive[/b], [i]natural order[/i] comparison to another string. Returns [code]-1[/code] if less than, [code]1[/code] if greater than, or [code]0[/code] if equal. "Less than" or "greater than" are determined by the [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode code points[/url] of each string, which roughly matches the alphabetical order. When used for sorting, natural order comparison orders sequences of numbers by the combined value of each digit as is often expected, instead of the single digit's value. A sorted sequence of numbered strings will be [code]["1", "2", "3", ...][/code], not [code]["1", "10", "2", "3", ...][/code]. With different string lengths, returns [code]1[/code] if this string is longer than the [param to] string, or [code]-1[/code] if shorter. Note that the length of empty strings is [i]always[/i] [code]0[/code]. To get a [bool] result from a string comparison, use the [code]==[/code] operator instead. See also [method naturalnocasecmp_to], [method nocasecmp_to], and [method casecmp_to]. Performs a [b]case-insensitive[/b], [i]natural order[/i] comparison to another string. Returns [code]-1[/code] if less than, [code]1[/code] if greater than, or [code]0[/code] if equal. "Less than" or "greater than" are determined by the [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode code points[/url] of each string, which roughly matches the alphabetical order. Internally, lowercase characters are converted to uppercase for the comparison. When used for sorting, natural order comparison orders sequences of numbers by the combined value of each digit as is often expected, instead of the single digit's value. A sorted sequence of numbered strings will be [code]["1", "2", "3", ...][/code], not [code]["1", "10", "2", "3", ...][/code]. With different string lengths, returns [code]1[/code] if this string is longer than the [param to] string, or [code]-1[/code] if shorter. Note that the length of empty strings is [i]always[/i] [code]0[/code]. To get a [bool] result from a string comparison, use the [code]==[/code] operator instead. See also [method naturalcasecmp_to], [method nocasecmp_to], and [method casecmp_to]. Performs a [b]case-insensitive[/b] comparison to another string. Returns [code]-1[/code] if less than, [code]1[/code] if greater than, or [code]0[/code] if equal. "Less than" or "greater than" are determined by the [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode code points[/url] of each string, which roughly matches the alphabetical order. Internally, lowercase characters are converted to uppercase for the comparison. With different string lengths, returns [code]1[/code] if this string is longer than the [param to] string, or [code]-1[/code] if shorter. Note that the length of empty strings is [i]always[/i] [code]0[/code]. To get a [bool] result from a string comparison, use the [code]==[/code] operator instead. See also [method casecmp_to], [method naturalcasecmp_to], and [method naturalnocasecmp_to]. Converts a [float] to a string representation of a decimal number, with the number of decimal places specified in [param decimals]. If [param decimals] is [code]-1[/code] as by default, the string representation may only have up to 14 significant digits, with digits before the decimal point having priority over digits after. Trailing zeros are not included in the string. The last digit is rounded, not truncated. [b]Example:[/b] [codeblock] String.num(3.141593) # Returns "3.141593" String.num(3.141593, 3) # Returns "3.142" String.num(3.14159300) # Returns "3.141593" # Here, the last digit will be rounded up, # which reduces the total digit count, since trailing zeros are removed: String.num(42.129999, 5) # Returns "42.13" # If `decimals` is not specified, the maximum number of significant digits is 14: String.num(-0.0000012345432123454321) # Returns "-0.00000123454321" String.num(-10000.0000012345432123454321) # Returns "-10000.0000012345" [/codeblock] Converts the given [param number] to a string representation, with the given [param base]. By default, [param base] is set to decimal ([code]10[/code]). Other common bases in programming include binary ([code]2[/code]), [url=https://en.wikipedia.org/wiki/Octal]octal[/url] ([code]8[/code]), hexadecimal ([code]16[/code]). If [param capitalize_hex] is [code]true[/code], digits higher than 9 are represented in uppercase. Converts the given [param number] to a string representation, in scientific notation. [codeblocks] [gdscript] var n = -5.2e8 print(n) # Prints -520000000 print(String.NumScientific(n)) # Prints -5.2e+08 [/gdscript] [csharp] // This method is not implemented in C#. // Use `string.ToString()` with "e" to achieve similar results. var n = -5.2e8f; GD.Print(n); // Prints -520000000 GD.Print(n.ToString("e1")); // Prints -5.2e+008 [/csharp] [/codeblocks] [b]Note:[/b] In C#, this method is not implemented. To achieve similar results, see C#'s [url=https://learn.microsoft.com/en-us/dotnet/standard/base-types/standard-numeric-format-strings]Standard numeric format strings[/url] Converts the given unsigned [int] to a string representation, with the given [param base]. By default, [param base] is set to decimal ([code]10[/code]). Other common bases in programming include binary ([code]2[/code]), [url=https://en.wikipedia.org/wiki/Octal]octal[/url] ([code]8[/code]), hexadecimal ([code]16[/code]). If [param capitalize_hex] is [code]true[/code], digits higher than 9 are represented in uppercase. Formats the string representing a number to have an exact number of [param digits] [i]after[/i] the decimal point. Formats the string representing a number to have an exact number of [param digits] [i]before[/i] the decimal point. Concatenates [param file] at the end of the string as a subpath, adding [code]/[/code] if necessary. [b]Example:[/b] [code]"this/is".path_join("path") == "this/is/path"[/code]. Repeats this string a number of times. [param count] needs to be greater than [code]0[/code]. Otherwise, returns an empty string. Replaces all occurrences of [param what] inside the string with the given [param forwhat]. Replaces all [b]case-insensitive[/b] occurrences of [param what] inside the string with the given [param forwhat]. Returns the index of the [b]last[/b] occurrence of [param what] in this string, or [code]-1[/code] if there are none. The search's start can be specified with [param from], continuing to the beginning of the string. This method is the reverse of [method find]. Returns the index of the [b]last[/b] [b]case-insensitive[/b] occurrence of [param what] in this string, or [code]-1[/code] if there are none. The starting search index can be specified with [param from], continuing to the beginning of the string. This method is the reverse of [method findn]. Returns the last [param length] characters from the end of the string. If [param length] is negative, strips the first [param length] characters from the string's beginning. [codeblock] print("Hello World!".right(3)) # Prints "ld!" print("Hello World!".right(-4)) # Prints "o World!" [/codeblock] Formats the string to be at least [param min_length] long, by adding [param character]s to the right of the string, if necessary. See also [method lpad]. Splits the string using a [param delimiter] and returns an array of the substrings, starting from the end of the string. The splits in the returned array appear in the same order as the original string. If [param delimiter] is an empty string, each substring will be a single character. If [param allow_empty] is [code]false[/code], empty strings between adjacent delimiters are excluded from the array. If [param maxsplit] is greater than [code]0[/code], the number of splits may not exceed [param maxsplit]. By default, the entire string is split, which is mostly identical to [method split]. [b]Example:[/b] [codeblocks] [gdscript] var some_string = "One,Two,Three,Four" var some_array = some_string.rsplit(",", true, 1) print(some_array.size()) # Prints 2 print(some_array[0]) # Prints "One,Two,Three" print(some_array[1]) # Prints "Four" [/gdscript] [csharp] // In C#, there is no String.RSplit() method. [/csharp] [/codeblocks] Removes a set of characters defined in [param chars] from the string's end. See also [method lstrip]. [b]Note:[/b] [param chars] is not a suffix. Use [method trim_suffix] to remove a single suffix, rather than a set of characters. Returns the [url=https://en.wikipedia.org/wiki/SHA-1]SHA-1[/url] hash of the string as a [PackedByteArray]. Returns the [url=https://en.wikipedia.org/wiki/SHA-1]SHA-1[/url] hash of the string as another [String]. Returns the [url=https://en.wikipedia.org/wiki/SHA-2]SHA-256[/url] hash of the string as a [PackedByteArray]. Returns the [url=https://en.wikipedia.org/wiki/SHA-2]SHA-256[/url] hash of the string as another [String]. Returns the similarity index ([url=https://en.wikipedia.org/wiki/S%C3%B8rensen%E2%80%93Dice_coefficient]Sorensen-Dice coefficient[/url]) of this string compared to another. A result of [code]1.0[/code] means totally similar, while [code]0.0[/code] means totally dissimilar. [codeblock] print("ABC123".similarity("ABC123")) # Prints 1.0 print("ABC123".similarity("XYZ456")) # Prints 0.0 print("ABC123".similarity("123ABC")) # Prints 0.8 print("ABC123".similarity("abc123")) # Prints 0.4 [/codeblock] If the string is a valid file path, converts the string into a canonical path. This is the shortest possible path, without [code]"./"[/code], and all the unnecessary [code]".."[/code] and [code]"/"[/code]. [codeblock] var simple_path = "./path/to///../file".simplify_path() print(simple_path) # Prints "path/file" [/codeblock] Splits the string using a [param delimiter] and returns an array of the substrings. If [param delimiter] is an empty string, each substring will be a single character. This method is the opposite of [method join]. If [param allow_empty] is [code]false[/code], empty strings between adjacent delimiters are excluded from the array. If [param maxsplit] is greater than [code]0[/code], the number of splits may not exceed [param maxsplit]. By default, the entire string is split. [b]Example:[/b] [codeblocks] [gdscript] var some_array = "One,Two,Three,Four".split(",", true, 2) print(some_array.size()) # Prints 3 print(some_array[0]) # Prints "One" print(some_array[1]) # Prints "Two" print(some_array[2]) # Prints "Three,Four" [/gdscript] [csharp] // C#'s `Split()` does not support the `maxsplit` parameter. var someArray = "One,Two,Three".Split(","); GD.Print(someArray[0]); // Prints "One" GD.Print(someArray[1]); // Prints "Two" GD.Print(someArray[2]); // Prints "Three" [/csharp] [/codeblocks] [b]Note:[/b] If you only need one substring from the array, consider using [method get_slice] which is faster. If you need to split strings with more complex rules, use the [RegEx] class instead. Splits the string into floats by using a [param delimiter] and returns a [PackedFloat64Array]. If [param allow_empty] is [code]false[/code], empty or invalid [float] conversions between adjacent delimiters are excluded. [codeblock] var a = "1,2,4.5".split_floats(",") # a is [1.0, 2.0, 4.5] var c = "1| ||4.5".split_floats("|") # c is [1.0, 0.0, 0.0, 4.5] var b = "1| ||4.5".split_floats("|", false) # b is [1.0, 4.5] [/codeblock] Strips all non-printable characters from the beginning and the end of the string. These include spaces, tabulations ([code]\t[/code]), and newlines ([code]\n[/code] [code]\r[/code]). If [param left] is [code]false[/code], ignores the string's beginning. Likewise, if [param right] is [code]false[/code], ignores the string's end. Strips all escape characters from the string. These include all non-printable control characters of the first page of the ASCII table (values from 0 to 31), such as tabulation ([code]\t[/code]) and newline ([code]\n[/code], [code]\r[/code]) characters, but [i]not[/i] spaces. Returns part of the string from the position [param from] with length [param len]. If [param len] is [code]-1[/code] (as by default), returns the rest of the string starting from the given position. Converts the string to an [url=https://en.wikipedia.org/wiki/ASCII]ASCII[/url]/Latin-1 encoded [PackedByteArray]. This method is slightly faster than [method to_utf8_buffer], but replaces all unsupported characters with spaces. Returns the string converted to [code]camelCase[/code]. Converts the string representing a decimal number into a [float]. This method stops on the first non-number character, except the first decimal point ([code].[/code]) and the exponent letter ([code]e[/code]). See also [method is_valid_float]. [codeblock] var a = "12.35".to_float() # a is 12.35 var b = "1.2.3".to_float() # b is 1.2 var c = "12xy3".to_float() # c is 12.0 var d = "1e3".to_float() # d is 1000.0 var e = "Hello!".to_int() # e is 0.0 [/codeblock] Converts the string representing an integer number into an [int]. This method removes any non-number character and stops at the first decimal point ([code].[/code]). See also [method is_valid_int]. [codeblock] var a = "123".to_int() # a is 123 var b = "x1y2z3".to_int() # b is 123 var c = "-1.2.3".to_int() # c is -1 var d = "Hello!".to_int() # d is 0 [/codeblock] Returns the string converted to lowercase. Returns the string converted to [code]PascalCase[/code]. Returns the string converted to [code]snake_case[/code]. Returns the string converted to uppercase. Converts the string to a [url=https://en.wikipedia.org/wiki/UTF-8]UTF-8[/url] encoded [PackedByteArray]. This method is slightly slower than [method to_ascii_buffer], but supports all UTF-8 characters. For most cases, prefer using this method. Converts the string to a [url=https://en.wikipedia.org/wiki/UTF-16]UTF-16[/url] encoded [PackedByteArray]. Converts the string to a [url=https://en.wikipedia.org/wiki/UTF-32]UTF-32[/url] encoded [PackedByteArray]. Converts the string to a [url=https://en.wikipedia.org/wiki/Wide_character]wide character[/url] ([code]wchar_t[/code], UTF-16 on Windows, UTF-32 on other platforms) encoded [PackedByteArray]. Removes the given [param prefix] from the start of the string, or returns the string unchanged. Removes the given [param suffix] from the end of the string, or returns the string unchanged. Returns the character code at position [param at]. Decodes the string from its URL-encoded format. This method is meant to properly decode the parameters in a URL when receiving an HTTP request. See also [method uri_encode]. [codeblocks] [gdscript] var url = "$DOCS_URL/?highlight=Godot%20Engine%3%docs" print(url.uri_decode()) # Prints "$DOCS_URL/?highlight=Godot Engine:docs" [/gdscript] [csharp] var url = "$DOCS_URL/?highlight=Godot%20Engine%3%docs" GD.Print(url.URIDecode()) // Prints "$DOCS_URL/?highlight=Godot Engine:docs" [/csharp] [/codeblocks] Encodes the string to URL-friendly format. This method is meant to properly encode the parameters in a URL when sending an HTTP request. See also [method uri_decode]. [codeblocks] [gdscript] var prefix = "$DOCS_URL/?highlight=" var url = prefix + "Godot Engine:docs".uri_encode() print(url) # Prints "$DOCS_URL/?highlight=Godot%20Engine%3%docs" [/gdscript] [csharp] var prefix = "$DOCS_URL/?highlight="; var url = prefix + "Godot Engine:docs".URIEncode(); GD.Print(url); // Prints "$DOCS_URL/?highlight=Godot%20Engine%3%docs" [/csharp] [/codeblocks] Returns a copy of the string with all characters that are not allowed in [method is_valid_filename] replaced with underscores. Returns a copy of the string with all characters that are not allowed in [member Node.name] removed ([code].[/code] [code]:[/code] [code]@[/code] [code]/[/code] [code]"[/code] [code]%[/code]). Returns a copy of the string with special characters escaped using the XML standard. If [param escape_quotes] is [code]true[/code], the single quote ([code]'[/code]) and double quote ([code]"[/code]) characters are also escaped. Returns a copy of the string with escaped characters replaced by their meanings according to the XML standard. Returns [code]true[/code] if both strings do not contain the same sequence of characters. Returns [code]true[/code] if this [String] is not equivalent to the given [StringName]. Formats the [String], replacing the placeholders with one or more parameters. To pass multiple parameters, [param right] needs to be an [Array]. [codeblock] print("I caught %d fishes!" % 2) # Prints "I caught 2 fishes!" var my_message = "Travelling to %s, at %2.2f km/h." var location = "Deep Valley" var speed = 40.3485 print(my_message % [location, speed]) # Prints "Travelling to Deep Valley, at 40.35 km/h."

[b]Note:[/b] In C#, this operator is not available. Instead, see [url=https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated]how to interpolate strings with "$"[/url]. Appends [param right] at the end of this [String], also known as a string concatenation. Appends [param right] at the end of this [String], returning a [String]. This is also known as a string concatenation. Returns [code]true[/code] if the left [String] comes before [param right] in [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode order[/url], which roughly matches the alphabetical order. Useful for sorting. Returns [code]true[/code] if the left [String] comes before [param right] in [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode order[/url], which roughly matches the alphabetical order, or if both are equal. Returns [code]true[/code] if both strings contain the same sequence of characters. Returns [code]true[/code] if this [String] is equivalent to the given [StringName]. Returns [code]true[/code] if the left [String] comes after [param right] in [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode order[/url], which roughly matches the alphabetical order. Useful for sorting. Returns [code]true[/code] if the left [String] comes after [param right] in [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode order[/url], which roughly matches the alphabetical order, or if both are equal. Returns a new [String] that only contains the character at [param index]. Indices start from [code]0[/code]. If [param index] is greater or equal to [code]0[/code], the character is fetched starting from the beginning of the string. If [param index] is a negative value, it is fetched starting from the end. Accessing a string out-of-bounds will cause a run-time error, pausing the project execution if run from the editor.
