1) The laser doors turn on when any actor approaches, not just enemies

2) When the dropship appears, it rains down some relatively heavy white particles that damage things below it

Did you make sure to place a unit close to the door (after placing it) for team definition?

I tried that, but still it turns on no matter what team is near it. Is there something in the Lua that's making it do that?

Well, I just checked and everything seems to work fine for me, maybe you should try first placing a unit and then placing a door near it because the way the door defines it's team is by checking the nearest actor's team and setting it as its own.

If there is a sophisticated way to define teams via player (Red/Green) check or something, i'd really like to know how to use it.

I know absolutely nothing about Lua, but I took a look at the code, and is it possible that when the door doesn't detect a team it assigns itself it's own team and attacks anyone in radius? I see something like a 60 pixel radius of initial detection, but I put the actor down before hand and put the door right next to it with no success.

On another note, maybe you could try using the vanilla doors as a detection base.(just a thought)

Btw, is the Acid Grenade Launcher supposed to have a 360 super large blast radius or a more directional blast like an "acid flak" of sorts?

However, I notice the revolver is quite weak, even when compared to the pistol.

I don't quite understand what you mean by this... Care to explain?

Methinks he said 'glue/put a very small actor/door very very close to the laser door as a means of detection', because vanilla doors auto-choose their team, that is, the team of the one who built it. Make one small enough to be detected by your door, yet won't pose a problem to the laser door.

I wanted to keep it balanced... Oh well, i'll make it take off heads with one shot...

Considering it's a revolver that's bigger than your arm, that's reasonable. Just make it has short sight range, maybe.

Not quite. Using AnimMode = 4, I was able to make another gun show a whole five frames when shooting. And spinup doesn't help anyway, as it always makes the animation play several times in a row, no matter what the duration variables are set to. Oh well, I guess I'll just follow your advice and transform the gun in a pseudo-attachable, then.
