first of all: please forgive me my bad english!
Im new to jME and just trying out some things. So today, i have programmed a little game with third person view like shown in Walking Character but:
in my game, the Golem is extremly lagging, whereas the tutorial doesn’t lag on my computer.
so i thought the reason is my game, but after hours off debbuging i didn’t found anything!
so i copied the code from Hello Collision and just add
Box b = new Box(Vector3f.ZERO, 1, 1, 1);
Geometry model = new Geometry(“Box”, b);
Material mat = new Material(assetManager, “Common/MatDefs/Misc/SolidColor.j3md”);
model.setLocalTranslation(0, 3, -7);
to have a moving Spatial.
and what did it do? LAGGING ON MOVING
please tell me, what’s the trick in Walking Character, i didn’t found it after hours
(its not the Animation, i disabled it while searching)
i didn’t knew that correct world positions are only available after updateGeometricState(), so i didn’t care about!
now i call updateGeometricState() twice:
- after Player has moved
- AND after camera has moved
and it works perfectly
so in conclusion: sorry for waste posting
I hope you dont call updateGeometricState on the single spatial, always use rootNode.updateGeometricState()!
