<?xml version="1.0" encoding="UTF-8" ?> <class name="Performance" inherits="Object" version="3.5"> <brief_description> Exposes performance-related data. </brief_description> <description> This class provides access to a number of different monitors related to performance, such as memory usage, draw calls, and FPS. These are the same as the values displayed in the [b]Monitor[/b] tab in the editor's [b]Debugger[/b] panel. By using the [method get_monitor] method of this class, you can access this data from your code. [b]Note:[/b] A few of these monitors are only available in debug mode and will always return 0 when used in a release build. [b]Note:[/b] Many of these monitors are not updated in real-time, so there may be a short delay between changes. </description> <tutorials> </tutorials> <methods> <method name="get_monitor" qualifiers="const"> <return type="float" /> <argument index="0" name="monitor" type="int" enum="Performance.Monitor" /> <description> Returns the value of one of the available monitors. You should provide one of the [enum Monitor] constants as the argument, like this: [codeblock] print(Performance.get_monitor(Performance.TIME_FPS)) # Prints the FPS to the console [/codeblock] </description> </method> </methods> <constants> <constant name="TIME_FPS" value="0" enum="Monitor"> Number of frames per second. </constant> <constant name="TIME_PROCESS" value="1" enum="Monitor"> Time it took to complete one frame, in seconds. </constant> <constant name="TIME_PHYSICS_PROCESS" value="2" enum="Monitor"> Time it took to complete one physics frame, in seconds. </constant> <constant name="MEMORY_STATIC" value="3" enum="Monitor"> Static memory currently used, in bytes.
