How to use dt in love.KeyPressed?

[rishavs]

the callback for love.KeyPressed takes only 3 args: key, scancode and isRepeat. It doesnt takes takes dt as an argument.

Should I use Love.Timer.GetDelta() in my KeyPressed callback?

Also, do you have a short snippet of using isRepeat in love.KeyPressed callback? For example, I am not sure how should I use the isRepeat value to move a ball with x and y position.

Finally, is there any chat channel where the community can be active in? some of these questions are not really issues and I hope I am not polluting the repo with them.

• i think is ok to use Love.Timer.GetDelta in KeyPressed callback .

• if you want move a ball , i think the best way to do is use Keyboard.IsDown in update phase. which just like:

      class MoveBall : Scene
      {
          const float speed = 40;
          Vector2 center = new Vector2(Graphics.GetWidth(), Graphics.GetHeight()) / 2f;
  
          public override void Draw()
          {
              Graphics.Circle(DrawMode.Fill, center, 10);
          }
  
          public override void Update(float dt)
          {
              if (Keyboard.IsDown(KeyConstant.Left)) center.X -= dt * speed;
              if (Keyboard.IsDown(KeyConstant.Right)) center.X += dt * speed;
              if (Keyboard.IsDown(KeyConstant.Down)) center.Y += dt * speed;
              if (Keyboard.IsDown(KeyConstant.Up)) center.Y -= dt * speed;
          }
      }

  Keyboard.Pressed only trigger one when you pressd your key or repate triggered in interval after you set Keyboard.SetKeyRepeat(true). it's not continuous.

I usually have a global DeltaTime that I set once per frame before everything else, and everything that needs a delta time simply reads this value. So I never pass a delta time in specific functions. Very simple.
