(Resolved, new issue) FLATSPRITE Crashes after a few seconds

[SamotnyOgorek]

Hi all, recently i've been messing around with GZDooM-specific stuff, and found this flag called +FLATSPRITE.
The first thing that came to my mind is to create an actor which is just a flat blood pool, so that i won't need to make a 3d model or make a really small 3d floor with a blood texture.
However, a few seconds after i load up a map with it, the game just crashes. If i can see it before it crashes, it will just freeze until it crashes...

Here's the decorate:

Code: Select all

ACTOR CucBloodPool 31000
{
	Scale 0.5
	Height 1
	Radius 25
	+FLATSPRITE
	+NOBLOCKMAP
	+DONTSPLASH
	+NOGRAVITY
	
	States
	{
		Spawn:
		TNT1 A 0 A_SetPitch(90)
		Goto Pool
		
		Pool:
		BSPL A 1
		Loop
	}
}

And here's an example .wad:

Thanks in advance

This bug has already been fixed for the next devbuild.

Doesnt crash now, but i cant seem to rotate it to sit on the floor properly...

I was about to post the same issue. Tried to use FLATSPRITE as a way to create blood decals and other decoration on the floor. I think I managed to get the offset just right so it is on the same level as the floor itself but viewed from certain angles it hides sprites "on top of it".

I think It's a sprite clipping / zbuffer thing. Flat or not, it's technically "in front of" the other sprite and so is rendered first. I imagine a possible solution would be more, smaller sprites instead (see the Droplets mod, which does this), so any overlap is less obvious.

I was thinking the same. So there is no was to make it always render in the background compared to other actors.
Edit: I only noticed now that OP has a different problem. Apply A_SetPitch (90) when you spawn it.
It won't work for pools of blood or other larger floor decals for the reasons I posted before.
