Nothing moving

Troubleshooting physics
1

Hello, for my scene with physics I followed HelloPhysics.java, but used the newer API style explained here: http://hub.jmonkeyengine.org/2011/01/18/changes-in-jmonkeyengine3-physics-system/



But none of my objects are moving. I also explicitly set gravity. For object creation, i did:



In my simpleInitApp() i have:

[java]

/** Set up Physics */

bulletAppState = new BulletAppState();

stateManager.attach(bulletAppState);

bulletAppState.getPhysicsSpace().setGravity(new Vector3f(0, 1f, 0));

bulletAppState.getPhysicsSpace().setAccuracy(0.005f);



[/java]



And:

[java]



sphere = new Sphere(32, 64, 0.25f);

sphereShape = new SphereCollisionShape(0.25f);

// sphere.setTextureMode(TextureMode.Projected);

geometry = new Geometry("ball", sphere);

geometry.setMaterial(material);

geometry.setLocalTranslation(pos);

final RigidBodyControl rigidBodyControl = new RigidBodyControl(sphereShape, 1f);

geometry.addControl(rigidBodyControl);

rootNode.attachChild(geometry);

[/java]



Any ideas?

you need to add the control/spatial to the physics space.

[java]bulletAppState.getPhysicsSpace().add(rigidBodyControl)[/java]

Sure enough that did it! Thanks. I thought that article was indicating that PhysicsSpace.add() was taken care of also with geometry.addControl().
