Having issues with my my 3d model animation.

[Zen3001]

I'm using blender with nash's md3 script(viewtopic.php?f=37&t=35790)
to create the model.

I didn't see any error anywhere during the whole process, and the model does get spawned in gzdoom but the animation just doesn't work.

here's a download link for the blend file and the pk3.

How many frames is the animation? If it is ten frames for example (0-9), then you have to make sure your MODELDEF contains all your frames in FrameIndex. 10 frames, so 10 FrameIndex entries.

[Zen3001]

just 3 frames

[R4L]

Okay, so you will need to add three FrameIndex entries. Something like:

Code: Select all • Expand view

FrameIndex LUMP A 0 0
FrameIndex LUMP B 0 1
FrameIndex LUMP C 0 2


If it's a decoration, just create a Spawn state for the object and loop through the frames:

Code: Select all • Expand view

Spawn:

LUMP ABC 3
Loop


[Zen3001]

you should take a look at the download I provided.
This looks exactly like my code, except I'm using zscript instead of decorate
and the zscript is written properly, there are no errors in the log and the model appears in gzdoom when I spawn the actor but only uses the first frame without any animation.

[Zen3001]

OK I tried using decorate instead, here's what I wrote:

Code: Select all • Expand view

ACTOR Dancer{
   States{
      Spawn:
         DANC ABCB 5
         Loop
   }
}

and in case you really don't want to click on that download link, here's the modeldef:

Code: Select all • Expand view

Model Dancer{
   Path "model"
   Model 1 "DANCER"
   Skin 1 "TEXTURE_"
   AngleOffset 90
   
   Scale 7.33 7.33 7.33
   
   FrameIndex DANC A 1 0
   FrameIndex DANC B 1 1
   FrameIndex DANC C 1 2
}

I opened your blend file, but I do not see any frames for animation. In fact, it says you have 250 frames, starting at 1. There are no keyframes though.

[Zen3001]

stupid me, wrong file...
retry the link please

[R4L]

The new blend file has keyframes, but again it is 250 frames long. Also, your keyframes actually end up being 80 frames total. You need to set the end frame, and then you will need to add more FrameIndex entries. The reason nothing happens is because you have 3 frames defined in MODELDEF, when there are actually 80 total frames. Test this in Blender by setting your end frame to 80, and play the animation. As it is now, the animation ends around frame 80, and then just sits and does nothing for 170 frames.

[Zen3001]

understand, so I just didn't knew how to use frames.
did everything you said and it's working now

Good job!
