Ragdolls disappearing

[Jazz]

Anyone have any idea why my ragdolls disappear when viewed at certain angles? Sometimes they can't be seen at all.

You have to update the AABB each loop.

      --Update the model local and global AABBs so the renderer keeps proper track of it
      model:UpdateAABB(Entity.LocalAABB)
      model:UpdateAABB(Entity.GlobalAABB)

Thanks Shadmar but there's no change after updating every loop.

[shadmar]

ok, I seem to remember that fixed my ragdolls, but I might be wrong. Tru turning off occlusion culling aswell.

in LE2, I had to also make the root physics body (the model in LE2), follow the ragdoll position/rotation as well or I would have that problem you are showing. In LE3, the hierarchy of mesh and physics body is swapped so I do not know if that would apply here. But I would be curious to where the entity and physics' aabb boxes end up. You should be able to visualize those by using the 'camera:SetDebugEntityBoxesMode()' and 'camera:SetDebugPhysicsMode()' and perhaps it will give an idea of what the problem could be if either of those is not following the ragdoll.

[Jazz]

Thanks for those commands. After the model's in ragdoll mode the collision hull keeps going to the next waypoint lol. With BoxesMode it's hard to tell as they all move around with the camera. Disabling culling doesn't help. I'll investigate later when I have some more time.

Found my project, just move the skin with the torso like each loop:

 

self.skin:SetPosition(self.torso:GetPosition()) --keep AABB inplace.

[Jazz]

I'll try that after work. Interesting what happens now though. The hull and AABB just get knocked away with the bullet impact.

 

edit: Hmm if I just set health to 0 they still fly away.

 

edit2: Thanks Shadmar! That did it!

Official LE3 feature ?

[Jazz]

No, but it would be nice to have built-in support.

You knocked the soul right out of him!

Ooh thanks for the idea!

I don't get it My character skin still disappears.

Is that "self.torso" a bone ?

in start: self.child = self.entity:FindChild("Bone")

 

Bone = top bone in the heirarchy

 

In your Update loop:

 

self.entity:SetPosition(self.child:GetPosition(true))

[tipforeveryone]

in start: self.child = self.entity:FindChild("Bone")

Bone = top bone in the heirarchy

In your Update loop:

self.entity:SetPosition(self.child:GetPosition(true))

Thank you SGB for your explanation, this works
