Detailed Description

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.

Member Function Documentation

◆ clear_window()

void FrameRateMeter::clear_window ( )

Undoes the effect of a previous call to setup_window().

Definition at line 136 of file frameRateMeter.cxx.

Referenced by setup_window().

◆ get_clock_object()

ClockObject * FrameRateMeter::get_clock_object ( ) const
inline

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

Definition at line 87 of file frameRateMeter.I.

◆ get_display_region()

DisplayRegion * FrameRateMeter::get_display_region ( ) const
inline

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

Definition at line 29 of file frameRateMeter.I.

◆ get_text_pattern()

const std::string & FrameRateMeter::get_text_pattern ( ) const
inline

Returns the sprintf() pattern that is used to format the text.

Definition at line 69 of file frameRateMeter.I.

◆ get_update_interval()

double FrameRateMeter::get_update_interval ( ) const
inline

Returns the number of seconds that will elapse between updates to the frame rate indication.

Definition at line 49 of file frameRateMeter.I.

◆ get_window()

GraphicsOutput * FrameRateMeter::get_window ( ) const
inline

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

Definition at line 19 of file frameRateMeter.I.

◆ set_clock_object()

void FrameRateMeter::set_clock_object ( ClockObject clock_object)
inline

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

The default is the application's global clock (ClockObject::get_global_clock()).

Definition at line 78 of file frameRateMeter.I.

◆ set_text_pattern()

void FrameRateMeter::set_text_pattern ( const std::string &  text_pattern)
inline

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.

Definition at line 59 of file frameRateMeter.I.

◆ set_update_interval()

void FrameRateMeter::set_update_interval ( double  update_interval)
inline

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.

Definition at line 40 of file frameRateMeter.I.

◆ setup_window()

void FrameRateMeter::setup_window ( GraphicsOutput window)

Sets up the frame rate meter to create a DisplayRegion to render itself into the indicated window.

Definition at line 88 of file frameRateMeter.cxx.

References NodePath::attach_new_node(), clear_window(), NodePath::node(), PandaNode::set_attrib(), NodePath::set_bin(), NodePath::set_material_off(), and NodePath::set_two_sided().

◆ update()

void FrameRateMeter::update ( )
inline

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.

Definition at line 97 of file frameRateMeter.I.
