CAnimatedMeshSceneNode + attached scene nodes drag

[BrianATSI]

In Irrlicht 1.8, If I attach scene nodes to an CAnimatedMeshSceneNode joint and move the scene around, the attached scene nodes seem to look like they drag behind.

I traced the issue to the OnAnimate( ) function. When OnAnimate is called... it calls getMeshForCurrentFrame() and inside that function it updates the joints absolute position BEFORE the parent node gets it's absolute position set (inside ISceneNode::OnAnimate() ).

To fix this problem I have to update the nodes absolute position each time it moves ahead of the scene manager's call to OnAnimate.

Also to note, the OnAnimate for the CBoneSceneNode is overridden and the updateAbsolutePosition is currently commented out. This makes it impossible to have position up-to-date for child nodes because the joint is always one frame behind on updating it's position inside OnAnimate from inside the CAnimatedMeshSceneNode
