Mike, using a repeat loop is pretty ineffecient and hard to control; I'd
recommend using "send" messages and then trap for the arrow keys going
down with the "on arrowKey" handler.
Something like this (I'm assuming an image is being moved, and escape
stops the game):
global gCurrentDirection
on StartGame
put "left" into gCurrentDirection
send "MoveObject" to me
end StartGame
on MoveObject
switch gCurrentDirection
case "up"
set the top of img 1 to (the top of img 1-1)
break
case "down"
set the bottom of img 1 to (the bottom of img 1+1)
break
case "left"
set the left of img 1 to (the left of img 1-1)
break
case "right"
set the right of img 1 to (the right of img 1+1)
break
end switch
send "MoveObject" to me in 20 milliseconds
end MoveObject
on arrowKey pDirection
put pDirection into gCurrentDirection
end arrowKey
on escapeKey
cancel (item 1 of the pendingMessages) -- assumes no other messages
are going on
end escapeKey
Hope this helps,
