It took me a while but here’s the code:
Main.java:

public class Main extends SimpleApplication {

private BulletAppState bulletAppState;
public Spatial straightPart, bentPart;
public static void main(String[] args) {
Main app = new Main();
app.start();
}
@Override
public void simpleInitApp() {
flyCam.setMoveSpeed(70F);
cam.setLocation(new Vector3f(-22.92931f, 2.6491745f, -0.17925507f));
cam.setRotation(new Quaternion(0.03900462f, 0.70585394f, -0.038985994f, 0.70620745f));
/*Spatial testDungeon = assetManager.loadModel("Scenes/Dungeon.j3o");
rootNode.attachChild(testDungeon);*/
Node dungeonParts = new Node();
straightPart = assetManager.loadModel("Models/dungeon_parts/straight.j3o");
DungeonGen.Dungeon dungeon = DungeonGen.generateDungeon(3, 3, this);
dungeon.attachToNode(dungeonParts);
rootNode.attachChild(dungeonParts);
viewPort.setBackgroundColor(ColorRGBA.Blue);
light = new PointLight();
light.setRadius(27F);
rootNode.addLight(light);
DirectionalLight light2 = new DirectionalLight();
light2.setDirection(new Vector3f(1,0,0));
rootNode.addLight(light2);
bulletAppState = new BulletAppState();
stateManager.attach(bulletAppState);
System.out.println("Root node children: " + rootNode.getChildren().size());
}
@Override
public void simpleUpdate(float tpf) {
light.setPosition(cam.getLocation());
}
@Override
public void simpleRender(RenderManager rm) {
//TODO: add render code
}
}
DungeonGen.java:
package dungeon.generation;

}
}
}
private void setPart(DungeonPart part, int index1, int index2){

break;

break;
}
}
}
return dungeon;
}
}
DungeonPart.java:
package dungeon.generation.parts;
import com.jme3.scene.Spatial;
/**

public abstract class DungeonPart {
protected Spatial representation;
public DungeonPart(int orientationCode) {
initOrientation(orientationCode);
}
public DungeonPart() {}
public Spatial getRepresentation() {
return representation;
}
protected abstract void initOrientation(int orientationCode);
}
And StraightPart.java:
package dungeon.generation.parts;
import com.jme3.asset.AssetManager;
import com.jme3.math.FastMath;
import com.jme3.math.Quaternion;
import com.jme3.math.Vector3f;
import dungeon.Main;
/**

public class StraightPart extends DungeonPart{
public static final int ROTATION_NORMAL = 0, ROTATION_90 = 1;
private Quaternion q = new Quaternion();
public StraightPart(Main m, int orientationCode) {
super();
representation = m.straightPart.clone();
}
@Override
protected void initOrientation(int orientationCode) {
if (orientationCode == ROTATION_90){
representation.setLocalRotation(q.fromAngleAxis(90* FastMath.DEG_TO_RAD, Vector3f.UNIT_Y));
}
}
}
I have tried waiting one frame (for worldTransform to be updated), but nothing happened.
