I want the green person to stay on the ground but I can't seem to change the physicslocation to appropriate. Do you have any idea? I took this program and just switched the character from oto to ninja: http://code.google.com/p/jmonkeyengine/source/browse/trunk/engine/src/test/jme3test/bullet/TestWalkingChar.java
Do you have any idea how I can make the camera zoom out so that the whole green person is displayed and change the location of the green person so that he is on the ground?
I've noticed that I can change the location of the main char with this
character.setPhysicsLocation(new Vector3f(-140f, 9.9f, -9f));
but when I put in lower y coordinates the main char drops through the ground and then floats way up in the sky like he ended up on the top of everything when he went through the ground. I could run the example with Oto perfectly, it's changing the main char to ninja that doesn't work for me.
Update
When using setlocaltranslationinstead of setphysicallocationmy main char gets located in the air:
Update 2
After scaling the main char:
model.scale(0.25f);
as suggested in the answer, the rendering is much better:
Update 2
After some more manipulation, it looks more like the way I want:
private void createCharacters() {
CapsuleCollisionShape capsule = new CapsuleCollisionShape(3f, 4f);
character = new CharacterControl(capsule, 0.01f);
model = (Node) assetManager.loadModel("Models/Ninja/Ninja.mesh.xml");
model.setLocalScale(0.15f);
// ninja.setViewDirection( new Vector3f( 1, 0, 1 ) );
// model.rotate(0.0f, -3.0f, 0.0f);
float scale = 0.25f;
model.scale(scale, scale, scale);
model.addControl(character);
character.setPhysicsLocation(new Vector3f(-141f, 10.5f, -9f));
model.setShadowMode(ShadowMode.CastAndReceive);
// model.setLocalTranslation(0, 50, 0);
character.setViewDirection(new Vector3f(1, 0, 0));
rootNode.attachChild(model);
getPhysicsSpace().add(character);
// BlenderKey blenderKey = new BlenderKey(
// "objects/creatures/alien/alien.mesh.xml");
// Node alien = (Node) assetManager.loadModel(blenderKey);
// alien.setLocalTranslation(new Vector3f(-145, 21, -10));
// rootNode.attachChild(alien);
BlenderKey blenderKey2 = new BlenderKey("Models/Oto/Oto.mesh.xml");
Spatial man = (Spatial) assetManager.loadModel(blenderKey2);
man.setLocalTranslation(new Vector3f(-140, 10, -10));
// man.setShadowMode(ShadowMode.CastAndReceive);
rootNode.attachChild(man);
}
