I'm so confused!

I'm so confused!

I had see so many topics about rotating a node/model and i can't find the answer that's why I have created this topic.

Ok, my question:

HOW TO ROTATE A MODEL, BY ITS X-AXIS?

ok, so

```   float gunAngle = 0;    Quaternion quat = new Quaternion();   Node rototum = new Node("Rototum!!");   public void doRotate(float frac, float i){         Vector3f vec = new Vector3f();       vec.set(0, 1, 0);       gunAngle = FastMath.PI*frac;       quat.fromAngleNormalAxis(gunAngle, vec);       rototum.setLocalRotation(quat);       rototum.updateGeometricState(0,true);       rototum.updateWorldVectors();       rototum.updateWorldBound();         }```

fraction is to attain different locations on the unit circle, notice it is frac * pi, so if you want 90 degrees, make frac = .5, etc

also, you can change the 1 position of Vector3fvec to rotate about different axises. rototum = to your node you want to rotate. that should work.

I was just wondering about these lines:

```rototum.updateGeometricState(0,true);       rototum.updateWorldVectors();       rototum.updateWorldBound();   ```

Aren't the two latter methods called in the former?

Hey, can i do it not in a method like doRotate? cause the model is in simpleGameInit, and i can't put a mthod in a method

Well write it outside then^^

Also I suggest learning the baiscs of java, else you wont get happy with jme;)
