**
I am wondering tho. the above solution calls for a var declaration in the onGui, with out a breaker. How taxing is this to the system? Is there an alternative?




Hi there,
running a simple OnGUI script with more then one btn....

function OnGUI()
{
if(GUI.RepeatButton())
blah;

if(GUI.RepeatButton())
blu;
}

the problem is that, the second btn disappears as long as the first is held.
This, for now is not a functional problem but an aesthetic one. How can I fix this?
