Determining which spatial is selected with a mouse cursor

Troubleshooting General Help
1

so i was looking at the hello collision tutorial and i was wondering how i would be able to click on the golem robot and make it disappear. lets say i created that world with two golems, how would you differentiate between the two identical golems? I understand how to do this with geometry shapes, just not spatials.



Edit: So i figured it out. All I have to do is getParent from geometry, which returns the spatial.



[java] if(name.equals("Select")) {

CollisionResults results = new CollisionResults();

Vector2f click2d = inputManager.getCursorPosition();

Vector3f click3d = cam.getWorldCoordinates(new Vector2f(click2d.x, click2d.y), 0f).clone();

Vector3f dir = cam.getWorldCoordinates(new Vector2f(click2d.x, click2d.y), 1f).subtractLocal(click3d).normalizeLocal();

Ray ray = new Ray(click3d, dir);

charactersNode.collideWith(ray, results);

if (results.size() > 0) {

// The closest collision point is what was truly hit:

CollisionResult closest = results.getClosestCollision();

Spatial temp = closest.getGeometry().getParent();

// System.out.println(temp.getName());

charactersNode.detachChild(temp);

}[/java]

bottom line: don’t jump to the tutorials that seem interesting but do them all from the beginning :roll:
