Hi,
I made an Animation, the character will fly from A to B and export it as Ogre to jme (3)
when I play the animation it will fly from A to B, but at the end of Animation it will teleport back to A.
are there any way to made the character setlocation at B at the end of Animation? or any way to get the location of B
I tried something in onAnimCycleDone , but it didnt work out for me
Depends on how you animated the model, you would have a root bone that contains the animation that shifts the character from A to B. In that case, you can find that bone using AnimControl.getBone(String) and track its position via Bone.getModelSpacePosition(). You can then set the character's position to that on your onAnimCycleDone callback.
Hi I tried this
@Override
public void onAnimCycleDone(AnimControl control, AnimChannel channel,String animName) {
p1.setLocalTranslation(animControl1.getSkeleton().getBone("head").getModelSpacePosition());
}
but it didnt work.There was though some position changing.
does it have to be a root bone or it doesnt matter? I just randomly chose the head bone, because the character flies, and head moves farthest.
The root bone in a rig is the first parent of the bone tree (hence the root).
Usually, it allow to move the entire model without deforming it.
Look here search root bone it's pretty well explained.

hope that helps
@Nehon
I have 2 roots or may be more
I can make all of them children of the new root Bone though.
But I wonder if any Bone will work, or it only works with root bone (and any root bone or only with the boss root bone }:-@)
:?
Ps Blender 2.53 is out ^^

Yep that is a good practice.

Well in fact it must be a bone that can move all the other ones of the rig. As long as child bones copy the translation of their parent, the "boss root bone" is a good candidate. :D

o/ gonna try that out!
Hi
I tried something and it didnt work ^^
- at the end of animation the mesh should have a new location (the end position of the animation)
- the right key work, but after animation it wont work anymore (dont know why, may be because of dontloop ?)
ModelSpacePosition is actually replacement of WorldLocation, there might be a new improvement there, but I dont know what. anyway, I feel like the Bone will always be somewhere at the middle of scrren and doesnt move along with mesh
This time I made a cube in Blender and only 1 bone. So 1 bone 1 mesh like Don Quixote 1 Spear 1 Horse against something in Holland ^^
and sure that only bone must be a rootBone or boss rootBone
I might upload the blender file if anyone need it (to operate the problem)
here is the code and the ogre xml
