Poisoncloud has infinite effect height

[Russell_P]

my first bug report, hope i'm doing this right.

Poison clouds seem to effect the player no matter how high they pass over them.

I'm using GZDoom 4.2.4 (from my ini...# This file was generated by GZDoom g4.2.4 on 2019-12-27 14:10:36#)

Here's a test wad for Doom2. I've included the cloud sprites and modifed the poison cloud to spawn a replacement on death.

That's because of OLDRADIUSDMG flag. I don't remember why it was added, there was some issue with "modern" damage radius code I guess.

The math in there doesn't work for the cloud. I've been thinking a few times that P_RadiusDamage really needs a third mode like OLDRADIUSDMG but with z-awareness and use that for the less strict compat flag.

Ah yes, I did read something about OLDRADIUSDMG but clearly I was half asleep at the time. I've just created an actor inheriting from PoisonCloud but with -OLDRADIUSDMG and that seems to have done the trick. Thanks for the help guys.
