[SOLVED] Problem with head bone rotation

Troubleshooting General Help
#21

I would generally do the animation and associate the frame ratio with the rotation of the camera. Accordingly, the client transmitted the keys to the animation.

Animation is simpler, you can also customize other bones, for realism. For example, bending the back.

But I am far behind you, my character can not walk yet :slight_smile:

Well, you are right, at a certain (rotation) angle I could let the back rotate for- and backwards instead of rotating the head even more.

However, this small check: if (!oldViewDir.equals(viewDirection)) is not that ā€œbadā€ in my opinion. Itā€™s easy to understand and at least a little optimized.

Nevertheless, you will make this :+1: :slight_smile:

So the head is not a child of the model? Else itā€™s difficult to see how a world-space view direction can properly set the angles for the child if the parent happens to be rotated.

Also ā€œunnecessary complicatedā€ is one call to worldToLocal().
Vector3f localViewDir = model.worldToLocal(viewDir.add(model.getWorldTranslation()), null);

Hehe, LOL :joy:

Wow, @pspeed you are awesome (and smart)!

I didnā€™t even think about the worldToLocal method, blame on me ā€¦

However, this code gets shorter every time :grin:

if (!oldViewDir.equals(viewDirection)) {
	getSpatial().worldToLocal(viewDirection.add(getSpatial().getWorldTranslation()), localViewDirection);
	finalHeadRotation.lookAt(localViewDirection, Vector3f.UNIT_Y);
	oldViewDir.set(viewDirection);
}

Wow, thank you again!
I feel so stupidā€¦ but I learned a lot today! Thanks!

Best regards
