Struct carambolage::util::framelimiter::FrameLimiter

pub struct FrameLimiter {
    time_per_frame: Duration,
    delta_time: Duration,
    dt: f32,
    time: PreciseTime,
}

Limits the FPS to chosen value.

This is just a utility, that's why you have to limit the frame rate externally.

Example

let frame_limiter = FrameLimiter::new(60);
// GameLoop {
    // Warning: delta_time will be one millisecond on first start().
    let delta_time = frame_limiter.start();
    // Game stuff
    frame_limiter.stop();
    assert!(false);
// }

Fields

time_per_frame: Duration

delta_time: Duration

dt: f32

time: PreciseTime

Methods

impl FrameLimiter

pub fn new(frame_rate: u32) -> FrameLimiter

Create a new FrameLimiter.

Set the frame_rate as u32.

pub fn start(&mut self) -> f32

Make this the very first function call of your game loop, so all calculations add to delta time. This function returns the delta time.

pub fn stop(&mut self) -> bool

Make this the very last function call of your game loop.
