Performance
|
|
===========
|
|
|
|
**Inherits:** :ref:`Object<class_Object>`
|
|
|
|
Exposes performance-related data.

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 **Monitor** tab in the editor's **Debugger** panel. By using the :ref:`get_monitor<class_Performance_method_get_monitor>` method of this class, you can access this data from your code.
|
|
|
|
\ **Note:** A few of these monitors are only available in debug mode and will always return 0 when used in a release build.
|
|
|
|
\ **Note:** Many of these monitors are not updated in real-time, so there may be a short delay between changes.

Method Descriptions

|
:ref:`float<class_float>` **get_monitor** **(** :ref:`Monitor<enum_Performance_Monitor>` monitor **)** |const|
|
|
|
|
Returns the value of one of the available monitors. You should provide one of the :ref:`Monitor<enum_Performance_Monitor>` constants as the argument, like this:
|
|
|
|
::
|
|
|
|
print(Performance.get_monitor(Performance.TIME_FPS)) # Prints the FPS to the console
|
|
|
|
.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
|
|
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
|
|
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
|
|
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
