On the steering of flying objects

General Discussion

Well I’ve been struggling for a while but I still can’t figure out how to get the wings to tilt when the flying object turns.

This video shows how the tank’s steering is currently meeting my expectations.

    @Override
    protected void controlUpdate(float tpf) {
        if (spatial != null) {
            if (i < move.size() - 1) {

                Vector3f currentPoint = spatial.getLocalTranslation();
                Vector3f nextPoint = move.get(i + 1);
                // Calculate the step of the node towards the next point
                Vector3f step = nextPoint.subtract(currentPoint).normalizeLocal().multLocal(tpf).multLocal(50f);

                Vector3f directionToTarget = nextPoint.subtract(currentPoint).normalizeLocal();
               
                Quaternion rotation=spatial.getLocalRotation();
                targetQua.lookAt(step, new Vector3f(0,1,0));
                rotation.nlerp(targetQua, 0.1f);
               float GoalAngle = Math.abs(spatial.getLocalRotation().dot(targetQua));
              // System.err.println("相似度：" + GoalAngle);

                 spatial.setLocalTranslation(currentPoint.add(step));
                // Check if you have reached the next point getLocalTranslation
                float distanceToNextPoint = spatial.getWorldTranslation().distance(nextPoint);
                // System.err.println(distanceToNextPoint);
                if (distanceToNextPoint < 0.2f ) {
                    //If the next point has been reached, update the current path index
                    i++;
                }

            }
        }
    }

I’m currently using this code to move.

Use this code to complete the turn

                Quaternion rotation=spatial.getLocalRotation();
                targetQua.lookAt(step, new Vector3f(0,1,0));
                rotation.nlerp(targetQua, 0.1f);

How do I tilt while steering and level when I’m done(Steer like an aeroplane.)?

//Please point out any confusion about my questions.

Up vector is 0,1,0 so of course up is always going to point exactly up. You could use a different up vector but probably you want to combine a roll rotation with this rotation.

For example:

// 45 degree roll
Quaternion roll = new Quaternion().fromAngles(0, 0, FastMath.QUARTER_PI);
rotation = rotation.mult(roll);

Thanks for the quick reply, I’m going to try it now
