[−][src]Struct amethyst_utils::fps_counter::FpsCounter
The FpsCounter resource needed by the FpsCounterSystem.
Add it to your resources to be able to use the FpsCounterSystem.
Usage
Get the FpsCounter resource from the world then call either frame_fps or sampled_fps to
get the FPS.
frame_fps will return the framerate of the current frame. That is, the framerate at which the game would be running if all frames were exactly like this one. sampled_fls will return the averaged framerate. This gives a better approximation of the "felt" framerate by the user.
Example
let mut counter = world.write_resource::<FpsCounter>();
Methods
impl FpsCounter[src]
pub fn new(samplesize: usize) -> FpsCounter[src]
Creates a new FpsCounter that calculates the average fps over samplesize values.
pub fn push(&mut self, elem: u64)[src]
Add a new delta time value.
pub fn frame_fps(&self) -> f32[src]
Get the fps of the this frame.
pub fn sampled_fps(&self) -> f32[src]
Get the average fps over the samplesize frames.
