Global scope constants and functions. A list of global scope enumerated constants and built-in functions. This is all that resides in the globals, constants regarding error codes, keycodes, property hints, etc. Singletons are also documented here, since they can be accessed from anywhere. For the entries related to GDScript which can be accessed in any script see [@GDScript]. $DOCS_URL/tutorials/math/random_number_generation.html Returns the absolute value of a [Variant] parameter [param x] (i.e. non-negative value). Supported types: [int], [float], [Vector2], [Vector2i], [Vector3], [Vector3i], [Vector4], [Vector4i]. [codeblock] var a = abs(-1) # a is 1 var b = abs(-1.2) # b is 1.2 var c = abs(Vector2(-3.5, -4)) # c is (3.5, 4) var d = abs(Vector2i(-5, -6)) # d is (5, 6) var e = abs(Vector3(-7, 8.5, -3.8)) # e is (7, 8.5, 3.8) var f = abs(Vector3i(-7, -8, -9)) # f is (7, 8, 9) [/codeblock] [b]Note:[/b] For better type safety, use [method absf], [method absi], [method Vector2.abs], [method Vector2i.abs], [method Vector3.abs], [method Vector3i.abs], [method Vector4.abs], or [method Vector4i.abs]. Returns the absolute value of float parameter [param x] (i.e. positive value). [codeblock] # a is 1.2 var a = absf(-1.2) [/codeblock] Returns the absolute value of int parameter [param x] (i.e. positive value). [codeblock] # a is 1 var a = absi(-1) [/codeblock] Returns the arc cosine of [param x] in radians. Use to get the angle of cosine [param x]. [param x] will be clamped between [code]-1.0[/code] and [code]1.0[/code] (inclusive), in order to prevent [method acos] from returning [constant @GDScript.NAN]. [codeblock] # c is 0.523599 or 30 degrees if converted with rad_to_deg(c) var c = acos(0.866025) [/codeblock] Returns the hyperbolic arc (also called inverse) cosine of [param x], returning a value in radians. Use it to get the angle from an angle's cosine in hyperbolic space if [param x] is larger or equal to 1. For values of [param x] lower than 1, it will return 0, in order to prevent [method acosh] from returning [constant @GDScript.NAN]. [codeblock] var a = acosh(2) # Returns 1.31695789692482 cosh(a) # Returns 2 var b = acosh(-1) # Returns 0 [/codeblock] Returns the difference between the two angles, in the range of [code][-PI, +PI][/code]. When [param from] and [param to] are opposite, returns [code]-PI[/code] if [param from] is smaller than [param to], or [code]PI[/code] otherwise. Returns the arc sine of [param x] in radians. Use to get the angle of sine [param x].

[codeblock] var a = asinh(0.9) # Returns 0.8088669356527824 sinh(a) # Returns 0.9 [/codeblock] Returns the arc tangent of [param x] in radians. Use it to get the angle from an angle's tangent in trigonometry. The method cannot know in which quadrant the angle should fall. See [method atan2] if you have both [code]y[/code] and [code skip-lint]x[/code]. [codeblock] var a = atan(0.5) # a is 0.463648 [/codeblock] If [param x] is between [code]-PI / 2[/code] and [code]PI / 2[/code] (inclusive), [code]atan(tan(x))[/code] is equal to [param x]. Returns the arc tangent of [code]y/x[/code] in radians. Use to get the angle of tangent [code]y/x[/code]. To compute the value, the method takes into account the sign of both arguments in order to determine the quadrant. Important note: The Y coordinate comes first, by convention. [codeblock] var a = atan2(0, -1) # a is 3.141593 [/codeblock] Returns the hyperbolic arc (also called inverse) tangent of [param x], returning a value in radians. Use it to get the angle from an angle's tangent in hyperbolic space if [param x] is between -1 and 1 (non-inclusive). In mathematics, the inverse hyperbolic tangent is only defined for -1 < [param x] < 1 in the real set, so values equal or lower to -1 for [param x] return negative [constant @GDScript.INF] and values equal or higher than 1 return positive [constant @GDScript.INF] in order to prevent [method atanh] from returning [constant @GDScript.NAN]. [codeblock] var a = atanh(0.9) # Returns 1.47221948958322 tanh(a) # Returns 0.9 var b = atanh(-2) # Returns -inf tanh(b) # Returns -1 [/codeblock] Returns the derivative at the given [param t] on a one-dimensional [url=https://en.wikipedia.org/wiki/B%C3%A9zier_curve]Bézier curve[/url] defined by the given [param control_1], [param control_2], and [param end] points.

The returned value will be between [code]0.0[/code] and [code]1.0[/code] if [param weight] is between [param from] and [param to] (inclusive). If [param weight] is located outside this range, then an extrapolation factor will be returned (return value lower than [code]0.0[/code] or greater than [code]1.0[/code]). Use [method clamp] on the result of [method inverse_lerp] if this is not desired. [codeblock] # The interpolation ratio in the `lerp()` call below is 0.75. var middle = lerp(20, 30, 0.75) # middle is now 27.5. # Now, we pretend to have forgotten the original ratio and want to get it back. var ratio = inverse_lerp(20, 30, 27.5) # ratio is now 0.75. [/codeblock] See also [method lerp], which performs the reverse of this operation, and [method remap] to map a continuous series of values to another. Returns [code]true[/code] if [param a] and [param b] are approximately equal to each other. Here, "approximately equal" means that [param a] and [param b] are within a small internal epsilon of each other, which scales with the magnitude of the numbers. Infinity values of the same sign are considered equal. Returns whether [param x] is a finite value, i.e. it is not [constant @GDScript.NAN], positive infinity, or negative infinity. Returns [code]true[/code] if [param x] is either positive infinity or negative infinity.

Returns [code]true[/code] if [param instance] is a valid Object (e.g. has not been deleted from memory). Returns [code]true[/code] if [param x] is a NaN ("Not a Number" or invalid) value. Returns [code]true[/code], for value types, if [param a] and [param b] share the same value. Returns [code]true[/code], for reference types, if the references of [param a] and [param b] are the same. [codeblock] # Vector2 is a value type var vec2_a = Vector2(0, 0) var vec2_b = Vector2(0, 0) var vec2_c = Vector2(1, 1) is_same(vec2_a, vec2_a) # true is_same(vec2_a, vec2_b) # true is_same(vec2_a, vec2_c) # false # Array is a reference type var arr_a = [] var arr_b = [] is_same(arr_a, arr_a) # true is_same(arr_a, arr_b) # false [/codeblock] These are [Variant] value types: [code]null[/code], [bool], [int], [float], [String], [StringName], [Vector2], [Vector2i], [Vector3], [Vector3i], [Vector4], [Vector4i], [Rect2], [Rect2i], [Transform2D], [Transform3D], [Plane], [Quaternion], [AABB], [Basis], [Projection], [Color], [NodePath], [RID], [Callable] and [Signal]. These are [Variant] reference types: [Object], [Dictionary], [Array], [PackedByteArray], [PackedInt32Array], [PackedInt64Array], [PackedFloat32Array], [PackedFloat64Array], [PackedStringArray], [PackedVector2Array], [PackedVector3Array] and [PackedColorArray]. Returns [code]true[/code] if [param x] is zero or almost zero. The comparison is done using a tolerance calculation with a small internal epsilon. This function is faster than using [method is_equal_approx] with one value as zero. Linearly interpolates between two values by the factor defined in [param weight]. To perform interpolation, [param weight] should be between [code]0.0[/code] and [code]1.0[/code] (inclusive). However, values outside this range are allowed and can be used to perform [i]extrapolation[/i]. If this is not desired, use [method clamp] on the result of this function. Both [param from] and [param to] must be the same type. Supported types: [int], [float], [Vector2], [Vector3], [Vector4], [Color], [Quaternion], [Basis]. [codeblock] lerp(0, 4, 0.75) # Returns 3.0 [/codeblock] See also [method inverse_lerp] which performs the reverse of this operation. To perform eased interpolation with [method lerp], combine it with [method ease] or [method smoothstep]. See also [method remap] to map a continuous series of values to another. [b]Note:[/b] For better type safety, use [method lerpf], [method Vector2.lerp], [method Vector3.lerp], [method Vector4.lerp], [method Color.lerp], [method Quaternion.slerp] or [method Basis.slerp]. Linearly interpolates between two angles (in radians) by a [param weight] value between 0.0 and 1.0. Similar to [method lerp], but interpolates correctly when the angles wrap around [constant @GDScript.TAU]. To perform eased interpolation with [method lerp_angle], combine it with [method ease] or [method smoothstep]. [codeblock] extends Sprite var elapsed = 0.0 func _process(delta): var min_angle = deg_to_rad(0.0) var max_angle = deg_to_rad(90.0) rotation = lerp_angle(min_angle, max_angle, elapsed) elapsed += delta [/codeblock] [b]Note:[/b] This function lerps through the shortest path between [param from] and [param to]. However, when these two angles are approximately [code]PI + k * TAU[/code] apart for any integer [code]k[/code], it's not obvious which way they lerp due to floating-point precision errors. For example, [code]lerp_angle(0, PI, weight)[/code] lerps counter-clockwise, while [code]lerp_angle(0, PI + 5 * TAU, weight)[/code] lerps clockwise. Linearly interpolates between two values by the factor defined in [param weight]. To perform interpolation, [param weight] should be between [code]0.0[/code] and [code]1.0[/code] (inclusive). However, values outside this range are allowed and can be used to perform [i]extrapolation[/i]. If this is not desired, use [method clampf] on the result of this function. [codeblock] lerpf(0, 4, 0.75) # Returns 3.0 [/codeblock] See also [method inverse_lerp] which performs the reverse of this operation. To perform eased interpolation with [method lerp], combine it with [method ease] or [method smoothstep]. Converts from linear energy to decibels (audio). This can be used to implement volume sliders that behave as expected (since volume isn't linear). [b]Example:[/b] [codeblock] # "Slider" refers to a node that inherits Range such as HSlider or VSlider. # Its range must be configured to go from 0 to 1. # Change the bus name if you'd like to change the volume of a specific bus only. AudioServer.set_bus_volume_db(AudioServer.get_bus_index("Master"), linear_to_db($Slider.value)) [/codeblock] Returns the [url=https://en.wikipedia.org/wiki/Natural_logarithm]natural logarithm[/url] of [param x] (base [url=https://en.wikipedia.org/wiki/E_(mathematical_constant)][i]e[/i][/url], with [i]e[/i] being approximately 2.71828). This is the amount of time needed to reach a certain level of continuous growth. [b]Note:[/b] This is not the same as the "log" function on most calculators, which uses a base 10 logarithm. To use base 10 logarithm, use [code]log(x) / log(10)[/code]. [codeblock] log(10) # Returns 2.302585 [/codeblock] [b]Note:[/b] The logarithm of [code]0[/code] returns [code]-inf[/code], while negative values return [code]-nan[/code].

[codeblock] mini(1, 2) # Returns 1 mini(-3, -4) # Returns -4 [/codeblock] Moves [param from] toward [param to] by the [param delta] amount. Will not go past [param to]. Use a negative [param delta] value to move away. [codeblock] move_toward(5, 10, 4) # Returns 9 move_toward(10, 5, 4) # Returns 6 move_toward(5, 10, 9) # Returns 10 move_toward(10, 5, -1.5) # Returns 11.5 [/codeblock] Returns the smallest integer power of 2 that is greater than or equal to [param value]. [codeblock] nearest_po2(3) # Returns 4 nearest_po2(4) # Returns 4 nearest_po2(5) # Returns 8 nearest_po2(0) # Returns 0 (this may not be expected) nearest_po2(-1) # Returns 0 (this may not be expected) [/codeblock] [b]Warning:[/b] Due to its implementation, this method returns [code]0[/code] rather than [code]1[/code] for values less than or equal to [code]0[/code], with an exception for [param value] being the smallest negative 64-bit integer ([code]-9223372036854775808[/code]) in which case the [param value] is returned unchanged. Wraps [param value] between [code]0[/code] and the [param length]. If the limit is reached, the next value the function returns is decreased to the [code]0[/code] side or increased to the [param length] side (like a triangle wave). If [param length] is less than zero, it becomes positive. [codeblock] pingpong(-3.0, 3.0) # Returns 3.0 pingpong(-2.0, 3.0) # Returns 2.0 pingpong(-1.0, 3.0) # Returns 1.0 pingpong(0.0, 3.0) # Returns 0.0 pingpong(1.0, 3.0) # Returns 1.0 pingpong(2.0, 3.0) # Returns 2.0 pingpong(3.0, 3.0) # Returns 3.0 pingpong(4.0, 3.0) # Returns 2.0 pingpong(5.0, 3.0) # Returns 1.0 pingpong(6.0, 3.0) # Returns 0.0 [/codeblock] Returns the integer modulus of [param x] divided by [param y] that wraps equally in positive and negative.

This distinguishes them from print messages used for debugging purposes, while also displaying a stack trace when an error or warning is printed. Converts one or more arguments of any type to string in the best way possible and prints them to the console. The following BBCode tags are supported: [code]b[/code], [code]i[/code], [code]u[/code], [code]s[/code], [code]indent[/code], [code]code[/code], [code]url[/code], [code]center[/code], [code]right[/code], [code]color[/code], [code]bgcolor[/code], [code]fgcolor[/code].

Hexadecimal color codes are not supported. URL tags only support URLs wrapped by a URL tag, not URLs with a different title. When printing to standard output, the supported subset of BBCode is converted to ANSI escape codes for the terminal emulator to display. Support for ANSI escape codes varies across terminal emulators, especially for italic and strikethrough. In standard output, [code]code[/code] is represented with faint text but without any font change. Unsupported tags are left as-is in standard output.

This distinguishes them from print messages used for debugging purposes, while also displaying a stack trace when an error or warning is printed. [b]Note:[/b] On Windows, only Windows 10 and later correctly displays ANSI escape codes in standard output. If verbose mode is enabled ([method OS.is_stdout_verbose] returning [code]true[/code]), converts one or more arguments of any type to string in the best way possible and prints them to the console. Prints one or more arguments to strings in the best way possible to standard error line. [codeblocks] [gdscript] printerr("prints to stderr") [/gdscript] [csharp] GD.PrintErr("prints to stderr"); [/csharp] [/codeblocks] Prints one or more arguments to strings in the best way possible to the OS terminal.

This method is generous with how it handles types, it can automatically convert between array types, convert numeric [String]s to [int], and converting most things to [String]. If the type conversion cannot be done, this method will return the default value for that type, for example converting [Rect2] to [Vector2] will always return [constant Vector2.ZERO].

Encodes a [Variant] value to a byte array. Encoding objects is allowed (and can potentially include executable code). Deserialization can be done with [method bytes_to_var_with_objects]. [b]Note:[/b] Encoding [Callable] is not supported and will result in an empty value, regardless of the data.

Returns a [WeakRef] instance holding a weak reference to [param obj]. Returns an empty [WeakRef] instance if [param obj] is [code]null[/code]. Prints an error and returns [code]null[/code] if [param obj] is neither [Object]-derived nor [code]null[/code]. A weak reference to an object is not enough to keep the object alive: when the only remaining references to a referent are weak references, garbage collection is free to destroy the referent and reuse its memory for something else. However, until the object is actually destroyed the weak reference may return the object even if there are no strong references to it. Wraps the [Variant] [param value] between [param min] and [param max]. Can be used for creating loop-alike behavior or infinite surfaces. Variant types [int] and [float] are supported. If any of the arguments is [float] this function returns a [float], otherwise it returns an [int].

Not all MIDI devices send this event; some send [constant MIDI_MESSAGE_NOTE_ON] with zero velocity instead. See the documentation of [InputEventMIDI] for information of how to use MIDI inputs. MIDI note ON message. Some MIDI devices send this event with velocity zero instead of [constant MIDI_MESSAGE_NOTE_OFF], but implementations vary. See the documentation of [InputEventMIDI] for information of how to use MIDI inputs. MIDI aftertouch message. This message is most often sent by pressing down on the key after it "bottoms out". MIDI control change message. This message is sent when a controller value changes. Controllers include devices such as pedals and levers. MIDI program change message. This message sent when the program patch number changes. MIDI channel pressure message. This message is most often sent by pressing down on the key after it "bottoms out".

[b]Note:[/b] If a built-in method returns this code, please open an issue on [url=https://github.com/godotengine/godot/issues]the GitHub Issue Tracker[/url]. Printer on fire error (This is an easter egg, no built-in methods return this error code). The property has no hint for the editor. Hints that an [int] or [float] property should be within a range specified via the hint string [code]"min,max"[/code] or [code]"min,max,step"[/code]. The hint string can optionally include [code]"or_greater"[/code] and/or [code]"or_less"[/code] to allow manual input going respectively above the max or below the min values. [b]Example:[/b] [code]"-360,360,1,or_greater,or_less"[/code]. Additionally, other keywords can be included: [code]"exp"[/code] for exponential range editing, [code]"radians_as_degrees"[/code] for editing radian angles in degrees (the range values are also in degrees), [code]"degrees"[/code] to hint at an angle and [code]"hide_slider"[/code] to hide the slider. Hints that an [int] or [String] property is an enumerated value to pick in a list specified via a hint string. The hint string is a comma separated list of names such as [code]"Hello,Something,Else"[/code]. Whitespaces are [b]not[/b] removed from either end of a name. For integer properties, the first name in the list has value 0, the next 1, and so on. Explicit values can also be specified by appending [code]:integer[/code] to the name, e.g. [code]"Zero,One,Three:3,Four,Six:6"[/code]. Hints that a [String] property can be an enumerated value to pick in a list specified via a hint string such as [code]"Hello,Something,Else"[/code]. Unlike [constant PROPERTY_HINT_ENUM], a property with this hint still accepts arbitrary values and can be empty. The list of values serves to suggest possible values. Hints that a [float] property should be edited via an exponential easing function. The hint string can include [code]"attenuation"[/code] to flip the curve horizontally and/or [code]"positive_only"[/code] to exclude in/out easing and limit values to be greater than or equal to zero. Hints that a vector property should allow its components to be linked. For example, this allows [member Vector2.x] and [member Vector2.y] to be edited together. Hints that an [int] property is a bitmask with named bit flags. The hint string is a comma separated list of names such as [code]"Bit0,Bit1,Bit2,Bit3"[/code]. Whitespaces are [b]not[/b] removed from either end of a name. The first name in the list has value 1, the next 2, then 4, 8, 16 and so on. Explicit values can also be specified by appending [code]:integer[/code] to the name, e.g. [code]"A:4,B:8,C:16"[/code]. You can also combine several flags ([code]"A:4,B:8,AB:12,C:16"[/code]). [b]Note:[/b] A flag value must be at least [code]1[/code] and at most [code]2 ** 32 - 1[/code]. [b]Note:[/b] Unlike [constant PROPERTY_HINT_ENUM], the previous explicit value is not taken into account. For the hint [code]"A:16,B,C"[/code], A is 16, B is 2, C is 4.

Hints that an [int] property is a bitmask using the optionally named 3D physics layers. Hints that an [int] property is a bitmask using the optionally named 3D navigation layers. Hints that an integer property is a bitmask using the optionally named avoidance layers. Hints that a [String] property is a path to a file. Editing it will show a file dialog for picking the path. The hint string can be a set of filters with wildcards like [code]"*.png,*.jpg"[/code]. Hints that a [String] property is a path to a directory. Editing it will show a file dialog for picking the path. Hints that a [String] property is an absolute path to a file outside the project folder. Editing it will show a file dialog for picking the path. The hint string can be a set of filters with wildcards, like [code]"*.png,*.jpg"[/code]. Hints that a [String] property is an absolute path to a directory outside the project folder. Editing it will show a file dialog for picking the path. Hints that a property is an instance of a [Resource]-derived type, optionally specified via the hint string (e.g. [code]"Texture2D"[/code]). Editing it will show a popup menu of valid resource types to instantiate. Hints that a [String] property is text with line breaks. Editing it will show a text input field where line breaks can be typed. Hints that a [String] property is an [Expression]. Hints that a [String] property should show a placeholder text on its input field, if empty. The hint string is the placeholder text to use. Hints that a [Color] property should be edited without affecting its transparency ([member Color.a] is not editable). Hints that the property's value is an object encoded as object ID, with its type specified in the hint string. Used by the debugger. If a property is [String], hints that the property represents a particular type (class). This allows to select a type from the create dialog. The property will store the selected type as a string. If a property is [Array], hints the editor how to show elements. The [code]hint_string[/code] must encode nested types using [code]":"[/code] and [code]"/"[/code].

Hints that a quaternion property should disable the temporary euler editor. Hints that a string property is a password, and every character is replaced with the secret character. Represents the size of the [enum PropertyHint] enum. The property is not stored, and does not display in the editor. This is the default for non-exported properties. The property is serialized and saved in the scene file (default). The property is shown in the [EditorInspector] (default). The property is excluded from the class reference. The property can be checked in the [EditorInspector]. The property is checked in the [EditorInspector]. Used to group properties together in the editor. See [EditorInspector]. Used to categorize properties together in the editor. Used to group properties together in the editor in a subgroup (under a group). See [EditorInspector]. The property is a bitfield, i.e. it contains multiple flags represented as bits. The property does not save its state in [PackedScene]. Editing the property prompts the user for restarting the editor. The property is a script variable which should be serialized and saved in the scene file. The property value of type [Object] will be stored even if its value is [code]null[/code]. If this property is modified, all inspector fields will be refreshed. Signifies a default value from a placeholder script instance. [i]Deprecated.[/i] This hint is not used anywhere and will be removed in the future. The property is an enum, i.e. it only takes named integer constants from its associated enumeration. If property has [code]nil[/code] as default value, its type will be [Variant]. The property is an array. When duplicating a resource with [method Resource.duplicate], and this flag is set on a property of that resource, the property should always be duplicated, regardless of the [code]subresources[/code] bool parameter. When duplicating a resource with [method Resource.duplicate], and this flag is set on a property of that resource, the property should never be duplicated, regardless of the [code]subresources[/code] bool parameter. The property is only shown in the editor if modern renderers are supported (the Compatibility rendering method is excluded). The [NodePath] property will always be relative to the scene's root. Mostly useful for local resources. Use when a resource is created on the fly, i.e. the getter will always return a different instance. [ResourceSaver] needs this information to properly save such resources. Inserting an animation key frame of this property will automatically increment the value, allowing to easily keyframe multiple values in a row. When loading, the resource for this property can be set at the end of loading. [i]Deprecated.[/i] This hint is not used anywhere and will be removed in the future. When this property is a [Resource] and base object is a [Node], a resource instance will be automatically created whenever the node is created in the editor. The property is considered a basic setting and will appear even when advanced mode is disabled. Used for project settings. The property is read-only in the [EditorInspector].
