Away3D Forum Drag3D on local XY plane?

Hi,

I want to drag/position a mesh inside a container, on a local XY plane for example, while the container is being turned/rotated. For example. I have a plane with some elements inside a PlaneContainer and I have eyes a motor for example also inside the PlaneContainer. I want to be able to reposition the motor, but on the same xy plane inside the PlaneContainer.

public function startDraggingInteraction() :void
{
 if (!_drag)
 {
  _drag = new Drag3D(_view, _mesh, Drag3D.PLANE_XY);
  _drag.debug = true;
  _drag.useRotations = true;
  _drag.planeObject3d = _mesh;
 }
 else
 {
  _drag.planeObject3d = _mesh;
 }
 
 _drag.planePosition = _mesh.scenePosition.clone();
 
 _isDragging = true;
 _view.addEventListener(Event.ENTER_FRAME, handleEnterFrame);
} 

in the Drag3D.updateNormalPlanes method it will calculated the normal of the obj… so world = false; But the plane on which I can drag the mesh seems to stay in the World coordinates.

Is it possible to have the the DraggingPlane setup locally?

Hopefully I made myself clear…

If I set the planePosition property… the Drag3D class recalculates the vital normal, which was set correctly by setting the planeObject… So I rewrote the following in the Drag3D class: public function set planePosition(pos:Vector3D):void { // switch (_planeid) { // //XZ // case PLANE_XZ: // _np.x = 0; // _np.y = 1; // _np.z = 0; // break; // //XY // case PLANE_XY: // _np.x = 0; // _np.y = 0; // _np.z = 1; // break; // //ZY // case PLANE_ZY: // _np.x = 1; // _np.y = 0; // _np.z = 0; // break; // } _a = -pos.x; _b = -pos.y; _c = -pos.z; _d = -(_a_np.x + _b_np.y + _c*_np.z); if (_debug) updateDebug(); } Now it works like a charm…
