Quickly clicking on a button

Question

I want to set a button up so it is activated and it's
function runs completely before it can be activated again. I have
tried a ton of things, but I can't get it to survive multiple
clicks. The swf does everything great so long as I click slowly but
kids are going to use this and they will be clicking like crazy. I
need a very basic example of how to set up and event listener and
it's associated function such that the FLV player associated with
it can change it's source and be ready to play the new source file
before the source can be changed again by the next button click or
better still only one button click is allowed until everything is
ready to play and any other button clicks are disreguarded.

Answer 1

Well if you use "on mouseUp" you can achieve that by adding a
global, for example called gBusy
Button Bhv:
global gBusy
on beginSprite me
gBusy = false
end beginSprite
on mouseUp me
if not(gBusy) then
gBusy = true --it will not enter here again if gBusy is
true.
startMyCustomFunction()
end if
end mouseUp
when the program finishes the execution, you MUST set gBusy =
false so the program can attend another mouseUp call.
for example:
on endMyFunction
gBusy = flase
end endMyFunction
