Rémi Verschelde 2d20fc39aa doc: Drop unused 'category' property from header
We already removed it from the online docs with #35132.

Currently it can only be "Built-In Types" (Variant types) or "Core"
(everything else), which is of limited use.

We might also want to consider dropping it from `ClassDB` altogether
in Godot 4.0.

</return>
<description>
Returns the frames per second of the running game.

<return type="int">
</return>
<description>
Returns the total number of frames passed since engine initialization which is advanced on each [b]idle frame[/b], regardless of whether the render loop is enabled. See also [method get_frames_drawn].

</method>
<method name="get_physics_interpolation_fraction" qualifiers="const">
<return type="float">
</return>
<description>
Returns the fraction through the current physics tick we are at the time of rendering the frame. This can be used to implement fixed timestep interpolation.

<argument index="0" name="name" type="String">
</argument>
<description>
Returns a global singleton with given [code]name[/code]. Often used for plugins, e.g. GodotPayments.

</method>
<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]

<method name="has_singleton" qualifiers="const">
<return type="bool">
</return>
<argument index="0" name="name" type="String">
</argument>
<description>
Returns [code]true[/code] if a singleton with given [code]name[/code] exists in global scope.
</description>
</method>
<method name="is_in_physics_frame" qualifiers="const">
<return type="bool">
</return>
<description>
Returns [code]true[/code] if the game is inside the fixed process and physics phase of the game loop.

<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="physics_jitter_fix" type="float" setter="set_physics_jitter_fix" getter="get_physics_jitter_fix" default="0.5">
Controls how much physic 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 in-game clock and real clock, but allows to 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.
</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.
