ZDoom

Does anyone know if a quicksand effect can be made? Im thinking it would be a nice touch to the wastelands in Hexen.

Maybe a sector that damages and lowers with transferred heights? It could raise back up when you leave the sector. It'd be pretty easy to make, just use the sector effect Things.

You can make a sector that is a platform and a 3d floor on top of that all using a sand texture. The 3d floor is in place just to cover your hole. When the player crosses a line into the sector you can disable their movement while triggering the platform to slowly go down onto the floor of the sector, if it has the water stuff enabled and set up you can drown in it. Just off the top of my head I guess that is how I would sort of try and do it.

Hmm, alright awesome, ill give it a shot tomorrow, ill leave another message here once ive done it.

Very late reply....but ive basically got it figured out, i still have to work with it a bit to make it perfect but it should be good. If i need anymore assistance ill message here again, thanks guys!

If there's a way to higher the viscosity of 3D water sectors, you could that and make the floor sector do damage (or instant death, depending on how deep it is).
