"return" basically kicks the program out of the function.. when the program hits that line, it exits the function immediately, and returns to the point just after where you called the function.

| Code: | function fly()
bx = bx-2
wx = wx-2
if crashup() then
return end
end |
is that right? cause it doesnt work. it just runs the function.
| Code: | function fly()
bx = bx-2
wx = wx-2
if y < uplimit then
return end
end
|
tried tat too. did nothing. by the way the bx and wx are just parts of the scrolling bg. i want it to stop scrolling when something happens. |

wekilledbambi03 (what a long username.:)
The if-then statement in your last code is not affected at all. The function will return to the same caller, no matter what the result of the logical expression is. I'd suggest to return either true or false, something like this:
| Code: |
function fly()
bx = bx-2
wx = wx-2
return (y < uplimit)
end
|
Note: the parenthesis pair is not required but for clarity's sake.
