Clientside Framerate calculation

[TheMysteriousVincent 20]

Hey there, folks!

I recently asked myself, how I can retrieve the current FPS of a client, because there is no inbuild function at all. Here's a small snippet for retrieving the current FPS in TypeScript (if you want to use it in JS just compile it with a TS transcompiler or adapt it 😐).

class FPSCalculator {
  private fps = 0;

  constructor() {
    let lastFrameCount = this.getFrameCount();
    setInterval(() => {
      this.fps = this.getFrameCount() - lastFrameCount;
      lastFrameCount = this.getFrameCount();
    }, 1000);
  }

  public get(): number {
    return this.fps;
  }

  private getFrameCount(): number {
    return mp.game.invoke('0xFC8202EFC642E6F2') as number; // '0xFC8202EFC642E6F2' is a method of GTA5 which returns the frame count since the game was started (see http://www.dev-c.com/nativedb/func/info/fc8202efc642e6f2 for ref.)
  }
}

export const FPS = new FPSCalculator();
