Simple enough question; is there a way to disable collision on an ACRocket, so that it passes through terrain/actors harmlessly? It's a remote target designator, basically.

Suggestions on how to make enemy actors ignore it would also be helpful, since it's something they shouldn't be able to see or shoot at.

Setting GetsHitByMOs and HitsMOs to 0 should disable collision with actors. I'm not quite sure how to go about getting through terrain undisturbed.

COULD be done (messily) by giving it a ridiculously high mass, and setting the depths of AtomGroup and DeepGroup to something really high. That'll leave a line of dots through the terrain, though.

And that is what it currently does.

The two MO settings only count bullets and projectiles; I already set those to 0 to ensure it wouldn't get hit.

Setting a 'null' sprite seems to do the trick apart from an extremely small line of pixels that is only rarely visible. Actors seem confused around it but at least they don't shoot at it, and it doesn't seem to be able to damage them.

Guess it'll have to do for now.
