[zDoom] Can I disable rocket jumping?

I managed to disable jumping and crouching via MAPINFO.

Can I also prevent player from performing rocket jumps (z-thrust)?

Create a custom player class and give it an OLDRADIUSDMG flag.

Put this code to your wad's DECORATE:

actor MyPlayer : DoomPlayer
{
  +OLDRADIUSDMG
}

And this code to your wad's MAPINFO:

GameInfo
{
   PlayerClasses = "MyPlayer"
}

Note that this will have a side effect of the player receiving damage if anything explodes even far above or far below him.

Works as expected, thanks!
