Examples of com.jme3.scene.Node.attachChild()

com.jme3.scene.Node.attachChild()
attachChild attaches a child to this node. This node becomes the child's parent. The current number of children maintained is returned.
If the child already had a parent it is detached from that former parent. @param child the child to attach to this node. @return the number of children maintained by this node. @throws IllegalArgumentException if child is null.
