panda3d.core.FrameRateMeter¶

class FrameRateMeter¶

Bases: TextNode

This is a special TextNode that automatically updates itself with the current frame rate. It can be placed anywhere in the world where you’d like to see the frame rate.

It also has a special mode in which it may be attached directly to a channel or window. If this is done, it creates a DisplayRegion for itself and renders itself in the upper-right-hand corner.

Inheritance diagram

__init__(param0: FrameRateMeter) → None¶

__init__(name: str) → None¶

clearWindow() → None¶: Undoes the effect of a previous call to setupWindow().

static getClassType() → TypeHandle¶

Return type: TypeHandle

getClockObject() → ClockObject¶

Returns the clock that is used to determine the frame rate.

Return type: ClockObject

getDisplayRegion() → DisplayRegion¶

Returns the DisplayRegion that the meter has created to render itself into the window to setupWindow(), or NULL if setupWindow() has not been called.

Return type: DisplayRegion

getTextPattern() → str¶: Returns the sprintf() pattern that is used to format the text.

getUpdateInterval() → float¶: Returns the number of seconds that will elapse between updates to the frame rate indication.

getWindow() → GraphicsOutput¶

Returns the GraphicsOutput that was passed to setupWindow(), or NULL if setupWindow() has not been called.

Return type: GraphicsOutput

setClockObject(clock_object: ClockObject) → None¶: Sets the clock that is used to determine the frame rate. The default is the application’s global clock (ClockObject.getGlobalClock()).

setTextPattern(text_pattern: str) → None¶: Sets the sprintf() pattern that is used to format the text. The string “%f” or some variant will be replaced with the current frame rate in frames per second.

setUpdateInterval(update_interval: float) → None¶: Specifies the number of seconds that should elapse between updates to the frame rate indication. This should be reasonably slow (e.g. 0.2 to 1.0) so that the calculation of the frame rate text does not itself dominate the frame rate.

setupWindow(window: GraphicsOutput) → None¶: Sets up the frame rate meter to create a DisplayRegion to render itself into the indicated window.

update() → None¶: You can call this to explicitly force the FrameRateMeter to update itself with the latest frame rate information. Normally, it is not necessary to call this explicitly.
