Hello, I got this script that changes the size of an object when you press Q. It’s C# btw.

	   if (Input.GetKeyDown(KeyCode.Q)) {
		Vector3 scale = transform.localScale;
		scale.y = 1F;
		transform.localScale = scale;
		}

I would like to change the size to 2F when you press Q again, how is that done?

Thanks, Andreas.

Well, the desired behaviour is unclear. What if Q was pressed a 3rd time? Should the scale return to 1F? And is 2F the original scale?

Supposing that you want to toggle between the original scale and half its size each time Q is pressed, you could use something like this:

// declare these variables outside any function:
float orgScale;
bool smallScale = false;

void Start(){
  orgScale = transform.localScale.y; // save the original scale
  // rest of original Start code
}

void Update(){
  if (Input.GetKeyDown(KeyCode.Q)){
    smallScale = !smallScale; // toggle current scale state
    Vector3 scale = transform.localScale;
    if (smallScale){
      scale.y = orgScale * 0.5f; // set scale to 50% of original value
    } else {
      scale.y = orgScale; // restore original value
    }
    transform.localScale = scale;
  }
  // rest of original Update code
}
