[Scenario]

I don't really get the point in having a tutorial for this. When you get the code WORKING, you go in-game and do testing, unless you are a complete idiot who feels testing is a waste of time. When you test things, you usually find a bug or two; I know I do. When you have found the bug, if you know enough about scripting you should be able to determine where it originated. Script bugs are similar to cancer; they originate somewhere but may spread throughout the script and then cause things to quit working like they should. Make sense?
