Addresses #30068 This is a prerequisite for allowing proper support for fixed timestep interpolation, exposing the interpolation fraction to the engine, modules and gdscript. The interpolation fraction is the fraction through the current physics tick at the time of the current frame.

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]

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.
