Can't get animated .iqm models working (UZDoom)

[lynn-m_beck]

Ok so I've been working on a mod that's a very early prototype for a UZDoom-based game I want to make (I'm doing it as a Doom mod for now, just because it already has assets and stuff defined which makes basic testing for mechanics and stuff a lot easier than if I had to define everything first; the actual game will be done from scratch in UZDoom).

For the game's Aesthetic™ (namely a pastiche of 2000s handheld FPSes), I want to use extremely crunchy 3D models for environmental details, and maybe also enemies/NPCs and certain pickups. I've managed to get a static model in, and it works fine, but now I'm trying to get an animated model working, and I'm having. Issues. Namely two:

1. Placing the object in the editor makes it use the sprite I assigned to it (which is repurposed from a placeholder sprite used elsewhere in the mod) rather than the model, and when I test it in-game, the model doesn't render and the collision doesn't work.
2. Trying to assign animations to sprite-frames like the ZDoom wiki describes returns an error about .iqm models not having frame names.

Here's the modeldef definition for the project:

Code: Select all

Model Coral{
	Path "models/coral"
	Model 0 "coraltest.iqm"
	Skin 0 "textures/models/CORAL.png"
	Scale 20 20 20
	
	FrameIndex BROC A 0 0
}
Model Testegg{
	Path "models/egg"
	Model 0 "eggtest.iqm"
	Skin 0 "textures/models/egg.png"
	scale 20 20 20
	
	Frame MARM A 0 "idle:0"
	Frame VEGE A 0 "pain:0"
}

The "coral" model works fine, but the "testegg" one doesn't.


And the Zscript definition for the "testegg" object, in case that's relevant:

Code: Select all

class testegg : Actor
{
	Default
	{
		Radius 24;
		Height 48;
		+SOLID
		+SHOOTABLE
	}
	States
	{
		Spawn:
			MARM A 1;
			Stop;
		Pain:
			VEGE A 1;
			Goto Spawn;
	}
}

I've tried looking this up, but I can't find anything about it, and I've tried everything listed on the wiki, none of which work. What, if anything, am I doing wrong?

Edit: trying again in a different file, and for some reason trying to import a .iqm with multiple animations comes back with an "Unable to read beyond the end of the stream" error, but looking this up comes up with stuff about unrelated programming languages, even if I specify ZDoom. This is really annoying since I really want to get around to actually making my game, but I can't if the models I make for it just flat-out don't work.

Ok so it turns out I should have been using decoupled animations the entire time? And also possibly I was having issues because I wasn't assigning a texture in Blender. It works now, so I can actually get back to working on my game!
