<method name="get_version_info" qualifiers="const">

<return type="Dictionary" />
|
|
<description>
|
|
Returns the current engine version information in a Dictionary.
|
|
[code]major[/code] - Holds the major version number as an int
|
|
[code]minor[/code] - Holds the minor version number as an int
|
|
[code]patch[/code] - Holds the patch version number as an int
|
|
[code]hex[/code] - Holds the full version number encoded as a hexadecimal int with one byte (2 places) per number (see example below)
|
|
[code]status[/code] - Holds the status (e.g. "beta", "rc1", "rc2", ... "stable") as a String
|
|
[code]build[/code] - Holds the build name (e.g. "custom_build") as a String
|
|
[code]hash[/code] - Holds the full Git commit hash as a String
|
|
[code]year[/code] - Holds the year the version was released in as an int
|
|
[code]string[/code] - [code]major[/code] + [code]minor[/code] + [code]patch[/code] + [code]status[/code] + [code]build[/code] in a single String
|
|
The [code]hex[/code] value is encoded as follows, from left to right: one byte for the major, one byte for the minor, one byte for the patch version. For example, "3.1.12" would be [code]0x03010C[/code]. [b]Note:[/b] It's still an int internally, and printing it will give you its decimal representation, which is not particularly meaningful. Use hexadecimal literals for easy version comparisons from code:
|
|
[codeblock]
|
|
if Engine.get_version_info().hex >= 0x030200:
|
|
# Do things specific to version 3.2 or later
|
|
else:
|
|
# Do things specific to versions before 3.2
|
|
[/codeblock]

<member name="editor_hint" type="bool" setter="set_editor_hint" getter="is_editor_hint" default="true">
|
|
If [code]true[/code], the script is currently running inside the editor. This is useful for [code]tool[/code] scripts to conditionally draw editor helpers, or prevent accidentally running "game" code that would affect the scene state while in the editor:
|
|
[codeblock]
|
|
if Engine.editor_hint:
|
|
draw_gizmos()
|
|
else:
|
|
simulate_physics()
|
|
[/codeblock]
|
|
See [url=https://docs.godotengine.org/en/3.3/tutorials/misc/running_code_in_the_editor.html]Running code in the editor[/url] in the documentation for more information.
|
|
[b]Note:[/b] To detect whether the script is run from an editor [i]build[/i] (e.g. when pressing [code]F5[/code]), use [method OS.has_feature] with the [code]"editor"[/code] argument instead. [code]OS.has_feature("editor")[/code] will evaluate to [code]true[/code] both when the code is running in the editor and when running the project from the editor, but it will evaluate to [code]false[/code] when the code is run from an exported project.

<member name="iterations_per_second" type="int" setter="set_iterations_per_second" getter="get_iterations_per_second" default="60">
|
|
The number of fixed iterations per second. This controls how often physics simulation and [method Node._physics_process] methods are run. This value should generally always be set to [code]60[/code] or above, as Godot doesn't interpolate the physics step. As a result, values lower than [code]60[/code] will look stuttery. This value can be increased to make input more reactive or work around tunneling issues, but keep in mind doing so will increase CPU usage.

</member>
|
|
<member name="physics_jitter_fix" type="float" setter="set_physics_jitter_fix" getter="get_physics_jitter_fix" default="0.5">
|
|
Controls how much physics ticks are synchronized with real time. For 0 or less, the ticks are synchronized. Such values are recommended for network games, where clock synchronization matters. Higher values cause higher deviation of the in-game clock and real clock but smooth out framerate jitters. The default value of 0.5 should be fine for most; values above 2 could cause the game to react to dropped frames with a noticeable delay and are not recommended.
|
|
[b]Note:[/b] For best results, when using a custom physics interpolation solution, the physics jitter fix should be disabled by setting [member physics_jitter_fix] to [code]0[/code].
|

</member>
|
|
<member name="target_fps" type="int" setter="set_target_fps" getter="get_target_fps" default="0">
|
|
The desired frames per second. If the hardware cannot keep up, this setting may not be respected. A value of 0 means no limit.
|
|
</member>
|
|
<member name="time_scale" type="float" setter="set_time_scale" getter="get_time_scale" default="1.0">
|
|
Controls how fast or slow the in-game clock ticks versus the real life one. It defaults to 1.0. A value of 2.0 means the game moves twice as fast as real life, whilst a value of 0.5 means the game moves at half the regular speed.
