		<member name="editor_hint" type="bool" setter="set_editor_hint" getter="is_editor_hint">
			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">
			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">
			The desired frames per second. If the hardware cannot keep up, this setting may not be respected. Defaults to 0, which indicates no limit.
		</member>
		<member name="time_scale" type="float" setter="set_time_scale" getter="get_time_scale">
			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.
