Example 1 with Control

use of com.jme3.scene.control.Control in project jmonkeyengine by jMonkeyEngine.

the class AnimationEvent method read.

    //FIXME always the same issue, because of the clonning of assets, this won't work
    //we have to somehow store userdata in the spatial and then recurse the 
    //scene sub scenegraph to find the correct instance of the model
    //This brings a reflaxion about the cinematic being an appstate, 
    //shouldn't it be a control over the scene
    // this would allow to use the cloneForSpatial method and automatically 
    //rebind cloned references of original objects.
    //for now as nobody probably ever saved a cinematic, this is not a critical issue
