Force touch to only work on a new touch - buttons

Hi, I am converting my buttons to touches since 2 GUI buttons doesn't work well when pressed together.

the problem is that when i turn it in to touch, I can't force the touch to cancel right after wards. I want to enforce the code to ONLY work on a new touch. (new touch meaning that the player has to lift their finger off the screen, then touch again --- like a button)

when it is a button, it works fine,

 if (GUI.Button (Rect, "", font)) {                        
 leftClick = true;    
                 }

 if(leftClick){
 //do somehting
 leftClick = false;
 }

This works fine because it only register a "click", the code would not count the continuous touch as a click.

but in touch , if i leave my finger on the "button" then I can't force the "button" to be unpressed (which I need to do). I tried using a tapCount to enforce the touch to be a tap , but that doesn't work.

 foreach (Touch t in Input.touches) {                    
                          
                             if (RightRect.Contains (t.position)&&t.tapCount==1) {
                                         rightClick = true;                                        
                                 }
                         }
                  

 

For example, in game you only want to allow one thing to pass a gate at a time, with gui buttons, the player can leave their finger on the button, but it will only allow one thing to pass. But in touch, if a player leave their finger on there, then it will allow all the things to pass and won't stop after 1 thing. So is there a way to cancel a touch after the user touches the button?

Thanks in advance!
