Nah, I just fixed the "Missile could not be located" issue with a lot easier way. Turns out in the previous Shootorial it says "Make sure ALL of your files are saved in the same folder." I saved them in different ones, causing an error. I fixed it! :D
@ Xlr83000: Where are spelling errors...? (btw, there's a spelling error in your comment)
@ Resrek: Thanks, man. I just found a platformer tutorial online and copied the code. The platformer they had though was 100% opposite mine considering the fact that it was a scroller... I wanted to try something like this. Maybe I should make a person and the exits but it's a scroller with less complex platforms.
