Hi,
try setting a flag before doing the flipping:
on keydown pkey
if pkey = "f" then
if not the hasFlipped of me then
set the hasFlipped of me to true
DoTheFlipping
end if
end if
pass keydown
end keydown
on keyUp pkey
if pkey = "f" then
DoThe_UN_Flipping
set the hasFlipped of me to false
end if
pass keyUp
end keyUp
Hth,
Malte
