Paul, Ken, et al,
It's alive!
My icon-changing stack, "Chameleon" is now changing icons on-the-fly.
Chameleon stack script:
local imagePath1,imagePath2,currentLibrary
on openStack
get the effective fileName of this stack
set the itemDelimiter to "/"
put "X2.rev" into item -1 of it
put it into imagePath1
put "X3.rev" into item -1 of it
put it into imagePath2
start using stack imagePath1
put imagePath1 into currentLibrary
refreshButtons
end openStack
on switchLibraries
set the itemDelimiter to "/"
get item -1 of currentLibrary
if it is "x3.rev" then
stop using stack imagePath2
close stack imagePath2
start using stack imagePath1
put imagePath1 into currentLibrary
else
stop using stack imagePath1
close stack imagePath1
start using stack imagePath2
put imagePath2 into currentLibrary
end if
send "refreshButtons" to this stack in 1 tick
end switchLibraries
on refreshButtons
repeat with x = 1 to the number of buttons
set the icon of button x to (the icon of button x)
end repeat
end refreshButtons
The key to making this work was sending "refreshButtons" to the stack
instead of calling it from the handler that switches the libraries.
Also, one must close the previous library [with destroyStack true],
not just stop using it.
So all you game builders who want to change the look and difficulty
as the user reaches each new level could address that with multiple
libraries containing images with the same icon id and handlers with
the same name but different logic.
It's gratifying when one's long-term hunch proves to be correct. :{`)
