ZDoom

If you spawn a monster at a map spot that is not at height 0, the stealth monster will stay a the same height it is spawned. It won't fall to the ground at all. While this is cool for some things, I think its a bug. Not sure if it does the same thing in the official version, though.

What monster are you talking about?

I tried it with a stealth demon, and a regular imp. The situtation I have was that I was making a building explode, and set the map spot heights to have missiles spawned and hit the walls. I entered the wrong number in Thing_Projectile, and I got the stealth demons, and they just floated there, and started attacking me (the ones that were low enough to). I tried it with T_Imp, and it did the same thing. Maybe it only does it with Thing_Projectile.

Thing_Projectile sets the NOGRAVITY flag. This is by design. No bug.

Oh, alrighty then. Thanks for the info, Graf.
