Hi guys, I have been looking for a while but cant seem to find an answer. If i use something like:

waitforbutttonpress

can I return the button which was pressed? for example:

button = waitforbuttonpress
 if button == rightMouse
   methodOne
 elseif button == leftMouse
   methodTwo
 else
 break
 end

It will not work. You cannot exit from loop this way. You only can start loop as one of the methods, However, if you start loop[ you will not be able to stop evaluation by mouse click because decision is outside the loop.
