如何在 Unity 中禁用 UI 多点触控？

Question

private void Awake()
{
    Input.multiTouchEnabled = false;
}  

public void touch()
{
    Score++;
}

This doesn't work.

Touch multiple times at once to increase your score multiple times. Help me to increment once even with multiple presses.

Answer 1

Just ignore touches, when finger count is > 1.

if (Input.touchCount == 1)
{
     Score++;
}

Answer 2

This depends a bit on how you detect the touch. With multiTouchEnabled set to false, you might still get a MouseDown event or something similar for some other than the first finger. Nevertheless, after a press, you can lock the functionality of increasing your score until you know there is no touch and then unlock it again.

bool locked = false;

//call this whenever you detect a touch, no matter how
public void Touch() {
 if(!locked){
   locked = true;
   score++; 
 }

void Update(){
  if(Input.touchCount == 0) locked = false;
}
