Well, I made a pretty cool gun that shoots plasma-balls.
The only problem is that the shot, which is an AEmitter, phases through almost all actors/doors. One of the only times I've seen it asplode on something else that terrain is a thick door. Help?

HitsMOs = 0

I think you set it to not hit MOs, in which case the above line of code is your problem. Change that 0 to a 1 and it'll hit actors (soldiers, doors, craft, etc.)

If you wanna change that faster, and change every similar line of code in the same .ini, go to "Edit", then "Replace" and type (in front of "Search"): HitsMOs = 0, and in front of "Replace by", type HitsMOs = 1.

Then it'll work the way you want it to.

Also, try giving it a larger sprite. If it's 2x2 or smaller it could have problems with collision.

I have already set HitsMOs to 1 and i have a larger than 3x3 sprite, but it still doesn't work.
