Arrows and Pagan Head

[grayman]

I'm testing AI reactions to finding dead and unconscious bodies.

 

As part of the test, I walk up behind one of the new Pagans and put an arrow in the back of his head.

 

Most of the time, it sails right through w/o hurting him.

 

Wassup with this?

 

Is the collision model correct for the new Pagan? He seems taller.

 

Or were there changes to arrow shooting and accuracy?

[Springheel]

Hmm? That certainly doesn't sound right. Which pagan?

Walk up behind him, aim at the middle of the back of his head, and most times the arrow flies right on through.

 

This is with the latest rev, 13330.

[Springheel]

I've confirmed this...if you shoot the area right near the middle of the back of his head, it goes right through. To either side or closer to the top of the head, it works normally. I have no idea why. I've never seen that before, and there's nothing noticeably odd about the model.

 

I can confirm that this also happens with some other versions of the head_08 model. The head_08_pagan and head_08_commoner_bare both have the problem. The version that has an extra hair layer does not seem to have the problem.

 

What's the command to show bounding boxes again?

[grayman]

g_showactiveentities 1

[grayman]

Created issue.

[Springheel]

g_showactiveentities 1

 

Hmm, that doesn't help...it doesn't show any of the heads as having bounding boxes.

[Springheel]

I tried g_showCollisionModels, which shows the head cms, but that didn't reveal anything out of the ordinary either. Well, I can probably hack something together to stop it from happening, but I'd love to know what's causing it.

[Springheel]

Well, my hacky solution gives the appearance of working for the base head_08, but the exact same solution does nothing for the pagan head_08, which is identical in virtually every way. wtf? This makes no sense at all.

[grayman]

Are you deleting the *.cm file and rebuilding after each change?

[Springheel]

The .cm file of the map? That wouldn't have any affect on md5meshes inside the map, would it?

[grayman]

I don't know. Just asking.

[Springheel]

I've narrowed down a few things. It has nothing to do with the texture. Spinning the head mesh around so the back of the head faces forward, I was able to reproduce the behaviour from the FRONT of the AI. This suggests the issue does actually have to do with that part of the mesh. I just have no idea what the issue is. But at least I know exactly what to tinker with.

[Baddcog]

are verts on the back of head welded?

Does the head have a collision model in it that might have a hole in it? That hair with collision would cover?

[Springheel]

Still have no idea as to the cause, but I've managed to hack together something that seems to solve it.
