I think this adheres to the rules. I've tried to stuff as much as I can into the 20 lines, so users with slower computers may experience problems. Oh, and there's no external media so you can just copy, paste and enjoy! Click to create ripples on the surface.



I'm going on the principle that if..else..endif, for..next and do..loop are all one command each. It's for dbpro, since db can't hack the massive long line I put in the middle. If you break it down and substitute some variables it should work in db.

Tell me what you think. I get 62fps.

'#100007: Variable " name is not valid at line 16.'

That's what I get...

That's not right...

It's removed the '>' and '<' symbols. Damn. I'll try removing the code tags...

Still doesn't work! The code that isn't in code tags will work, but the code in code tags doesn't. Hmm... One more time:

Yeah! It works!! Could the moderator please delete this topic, since I've started up a new one with code that works.

Thanks for the edit D Man, but you just appear to have replaced some of the '<'s with '*'s, so the overall effect is different to intended.
