Passing Values into ActionManager ExecuteCodeAction


Recommended Posts

I am having another noob "this" moment. I'm working on a simple class.... These are a few snips of the problem area.

When I call a method such as nodeActions below which binds actions to a mesh, then I click on the mesh triggering moveToNode, the this scope changes to actionManager's this instead of this classes this. Why this happens makes sense to me, but what is the best way to access the classes this scope from within moveToNode so I don't have to do such a sloppy hack to re access scene and my class variables from within the moveToNode method?       

        var scene = this._actionManager._scene //HACK
        var pickedNode = scene.pick(scene.pointerX, scene.pointerY, null, false, scene.camera)
        var moveTarget = scene.getMeshByName(pickedNode.name)
        // More to come this is not a simple interpolate function

nodeActions(mesh) {
        mesh.actionManager = new BABYLON.ActionManager(this.scene)
        mesh.actionManager.registerAction( new BABYLON.ExecuteCodeAction(BABYLON.ActionManager.OnPickTrigger, this.moveToNode))
