Translations and MouseEvents

[mogg]

I have an ObjectContainer3D which contains a few other objects. Each
of these child object respond to a MouseEvent3D.

The ObjectContainer3D can be rotated in X,Y,and Z.

The Child objects are also moving around based on basic AI.

When I click a child object and get the resulting MouseEvent3D I
attempting to use the event.sceneX,Y,Z.

How can I translate this result to move a child object to the same
point inside the ObjectContainer3D?

I didn't get that. Could you please try explaining again?

Hmm, nothing we have in the engine will do this for you, but you could always try and write a little 'globalToLocal" method for obejct3d to do just that yourself. Essentially you need to take the x y and z positions in the scene and multiply the resulting number3d by the inverse matrix3d of the sceneTransform property of the object.

Rob,

Thank you. I will try that.

Rob,

THANK YOU! Got it working as desired with your recommendations with
the current trunk... Thank you, Thank you, Thank you!

I can now rotate the scene in any direction and click on any object
(other than the center ship) and hit those objects with phasors in the
very spot I clicked. If I click on the nacel or bridge I get hits in
those specific areas. Again... Thank you!

I did the following to create a globalToLocal transformation:

var v:Vertex = new Vertex(event.sceneX,event.sceneY, event.sceneZ);
var m:Matrix3D = new Matrix3D();
var m2:Matrix3D = new Matrix3D();
var m3:Matrix3D = new Matrix3D();
m.clone(this._innerContainer.transform);
m2.clone(this._outerContainer.transform);
m3.multiply(m2,m);
m.inverse(m3);
v.transform(m);

Jensa,

Don't worry. Rob's recommendation answered my question.
