Need help with complex hitTest project

Hi all,

I’m trying to develop an application similar to[SIZE=1][SIZE=2][SIZE=2]

However, mine has to work for 128 nodes, so needless to say, using hitTest and onEnterFrame is a disaster when there are 128 nodes.
I can show you some code, but I don’t think it helps.

I need to know how I can drag a node and make ALL the other nodes move if they overlap.

So the problem here is not moving nodes from the dragged node’s path. The problem is that when you have a screen full of nodes and a node moves to make way, it will overlap with other nodes, and in turn they have to move.

Can anyway give me hint on how this can be done.

I would really appreciate an answer.
