Enable/Disable Touch during runtime.

Good day All, I am having problems enabling/disabling touch during runtime. What I need is a code to quickly disable the main touch and then enable it again for play. As it stands the code works perfectly if I comment out the if(transitionwait) however the minute I include it and disable it when it gets triggered again it refuses to correctly trigger Button1 correctly. currently my code is as follows.

if(transitionwait) { foreach (Touch t in Input.touches) { Vector2 vec = t.position; vec.y = Screen.height - vec.y; //inverted GUI and screen have different coordinate system.

 if (Button1.Contains (vec)) 
 {
     insidebutton (1);
 }

}

where I am setting transitionwait as follows.

.... transitionwait = false; StartCoroutine(Waiting()); ....

IEnumerator Waiting(); { yield return new WaitForSeconds(0.1f); transitionwait = true;

}

I have no errors for compiling so any spelling errors were created from me retyping.

Thanks all!
