mf_noclipthing is incorrect and will prevent player hazard interaction. you want mf_noclip|mf_noclipheight

wait no you don't. just remove all noclip properties and just have special alone

I'm going to edit this in SOC to test out all your different suggestions and the original MR

MF_NOCLIPTHING|MF_SPECIAL fixes the issue, prevents player interaction like toaster said

MF_NOCLIP|MF_NOCLIPHEIGHT|MF_SPECIAL fixes the issue

MF_SPECIAL also fixes the issue... there seems to be no difference with the above but I think it would be best to have MF_NOCLIPHEIGHT just in case.

Oh, interesting; I was under the impression that MF_NOCLIPTHING was just MF_NOCLIP but with wall collision. (The wiki pitches it that way.) I should have done more research, thanks for the catch!

MF_SPECIAL alone is the best case here; MF_NOCLIPHEIGHT makes it so that objects can fall through the floor, which is not the intended behavior for the gas.

Compare with previous version

If the wiki says that, the wiki is incorrect! I like to think of it as:

• noclip is the cheat code with upwarping
• noclipheight is falling through the floor but with nogravity is the necessary companion to noclip to prevent upwarping
• noclipthing is just ignoring all objects regardless of solid or not

technically MF_NOCLIP does also ignore all objects though

I've actually been meaning to ask why it does that for awhile MI, it seems a bit strange that noclip ignores objects, I've ran into problems in the past regarding this, specifically there was this one time where I wanted a projectile to be able to go through walls & floors while still being able to kill badniks, but I just couldn't since noclip also disables enemy collision. If you was to want noclip + no object collision you could just use MF_NOCLIP and MF_NOCLIPTHING at the same time, so it just doesn't make much sense to me why MF_NOCLIP needs no object collision too.
