TestPhysicsHingeJoint.java is not working in eclipse

I was testing the Sample Code (TestPhysicsHingeJoint.java) in Eclipse. what is the problem with the error?


package jme3test.bullet;

import com.jme3.app.SimpleApplication;
import com.jme3.bullet.BulletAppState;
import com.jme3.bullet.PhysicsSpace;
import com.jme3.bullet.collision.shapes.BoxCollisionShape;

import com.jme3.math.Vector3f;
import com.jme3.scene.Node;

public class TestPhysicsHingeJoint extends SimpleApplication implements AnalogListener{
	private BulletAppState bulletAppState;
	private HingeJoint joint;
	public static void main(String [] args) {
		TestPhysicsHingeJoint app = new TestPhysicsHingeJoint();
	private void setupKeys() {
		inputManager.addMapping("Left", new KeyTrigger(KeyInput.KEY_H));
		inputManager.addMapping("Right", new KeyTrigger(KeyInput.KEY_K));
		inputManager.addMapping("Swing", new KeyTrigger(KeyInput.KEY_SPACE));
		inputManager.addListener(this, "Left", "Right", "Swing");
	public void onAnalog(String binding, float value, float tpf) {
		if(binding.equals("Left")) {
			joint.enableMotor(true, 1, .1f);
		else if(binding.equals("Right")) {
			joint.enableMotor(true, -1, .1f);
		else if(binding.equals("Swing")) {
			joint.enableMotor(false, 0, 0);
	public void simpleInitApp() {
		bulletAppState = new BulletAppState();
	private PhysicsSpace getPhysicsSpace() {
		return bulletAppState.getPhysicsSpace();
	public void setupJoint() {
		Node holderNode=PhysicsTestHelper.createPhysicsTestNode(assetManager, new BoxCollisionShape(new Vector3f( .1f, .1f, .1f)),0);
		holderNode.getControl(RigidBodyControl.class).setPhysicsLocation(new Vector3f(0f,0,0f));
		Node hammerNode=PhysicsTestHelper.createPhysicsTestNode(assetManager, new BoxCollisionShape(new Vector3f( .3f, .3f, .3f)),1);
		hammerNode.getControl(RigidBodyControl.class).setPhysicsLocation(new Vector3f(0f,-1,0f));
		joint=new HingeJoint(holderNode.getControl(RigidBodyControl.class), hammerNode.getControl(RigidBodyControl.class), Vector3f.ZERO, new Vector3f(0f,-1,0f), Vector3f.UNIT_Z, Vector3f.UNIT_Z);
	public void simpleUpdate(float tpf) {

its only in Eclipse?

Anyway i would suggest try:

  • use LWJGL3 / try disable/enable hardware skinning
  • Use Minie library(its same bullet lib, but better maintained)

hope others will know more, but myself i see this error first time.

So I ran that code in the jMonkey SKD, not eclipse. I had errors in the setupJoint() method because PhysicsTestHelper is it’s own file.


Make sure you have that in your project–
