		<method name="get_version_info" qualifiers="const">
			<return type="Dictionary">
			</return>
			<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 &gt;= 0x030200:
				    # Do things specific to version 3.2 or later
				else:
				    # Do things specific to versions before 3.2
				[/codeblock]

	<members>
		<member name="editor_hint" type="bool" setter="set_editor_hint" getter="is_editor_hint" default="true">
			If [code]true[/code], it is running inside the editor. Useful for tool scripts.
		</member>
		<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 (for fixed process and physics).

		</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.
