I have seen and used custom power-ups (scriptable) ones that allow players to become invincible and immune to all damage until they jump off a map or leave the map boundries. I've been trying to figure out how it is possible to script this but I can't find any answers. Can anyone help me out?
hmm... I've thought about it, too. But the best way is really to use the mini-game mode and while a person is labelled by the power-up, they get certain traits applied to them. In your case, invicibility. However, I'm trying to come up with a way to script it outside of mini-game mode. If I have success, you'll see a thread here at some point.
there is one in H3 I think... could be trying to recreate that. But, yeah, it probably does need a mini-game mode, so he might as well incorporate some other sort of gameplay elements into it.
