Yeah sure. You can use it as long as you put my name in the description. For scripting, watch this video. Its teaching off a really old version of Phun (not Algodoo) but it still applies for Algodoo.
After downloading this, I figured out a really fun thing to do. Make the script e.geom.attraction = 100; e.geom.density = 100. Then make a bunch of objects, or just put a breakable ragdoll, and put the objects/ragdoll into the laser. Instant death.
Yep! That bots good! Technically you were sopossed to post the link in the comments for the page I had in the description for this scene, but its fine. Good luck in the tournament!
Also, it may be a while till the tournament begins, since people seem to be joining very slowly, and you were only the first.
