Adding a callback to a ticker....with parameters?


Recommended Posts

Hi devs,

 

In my project I have a number of GameObjects, each of which have a sprite attribute which is a derivative class of Pixi.Sprite. That doesn't really matter but just some background. Here's the issue:

 

  public startGame(): void {
    this.running = true
    this.app.ticker.start()
    for (const go of this.gameObjects) {
      go.sprite.dragDisable();
      go.sprite.start()
      this.app.ticker.add(go.sprite.update, go.sprite) // this is the problem
    }
  }

 

It is important that I can pass in go.sprite in as a context!

Each of my sprites have an update method, but it takes in a delta parameter:

update(delta: number): void;

 

So how can I add these callbacks to my ticker but pass in delta time?

 

Thanks

Peter

It looks correct. Doesn't the delta get passed or what is the issue? You are adding a function that has delta parameter to ticker with the context of the sprite so it should work.
