Trait game_time::framerate::counter::FrameCount [−] [src]

pub trait FrameCount: Debug {
    fn target_frame_rate(&self) -> f64;
    fn target_time_per_frame(&self) -> FloatDuration;
    fn remaining_frame_time(&self, time: &GameTime) -> FloatDuration;

}

A frame rate counter and tracker.

Required Methods

`fn target_frame_rate(&self) -> f64`

The target frame rate for the simulation.

`fn target_time_per_frame(&self) -> FloatDuration`

The target wall time for each frame.

`fn remaining_frame_time(&self, time: &GameTime) -> FloatDuration`

The duration remaining to reach the optimal frame time.

The duration can be negative if the current frame has executed longer than the optimal time.

`fn tick(&mut self, time: &GameTime)`

Update the counter for a new frame.

`fn average_frame_rate(&self) -> f64`

The average frame rate for the current frame.

`fn is_running_slow(&self, time: &GameTime) -> bool`

Return whether the simulation is running slowly.
