wait key

[CODE/]

-----------------------------------------------------------

This is my unfinished game. The problem is, when i go to move all alien ships, and command it to use index 1 in the spritenum array, it tells me that the sprite does not exsist.
Copy it into DBPRO yourself if you want.
Please help!!!

RE: MOVING SPRITE HELP!!!

Try putting before EVERY command that has to do with sprites 'if sprite exist(sprnr) = 1' and after it 'endif'.
