Drag and Drop Objects with Line Between

[jbum]

This is a frame script. It assumes the blue square and the green square are movieclips that have been assigned the names mc1 and mc2.

If you want the lines to issue from a particular corner, orient the movieclips so that the crosshairs correspond to that corner.

I prefer to have the lines issue from the center (so I keep the crosshair centered).

code:

---

_root.createEmptyMovieClip("line_mc", 1);



MovieClip.prototype.drawLine = function()

{

	this.clear();

	this.lineStyle(2,0xFF0000,100);

	this.moveTo(mc1._x, mc1._y);

	this.lineTo(mc2._x, mc2._y);

}



// insure movieclips are in front of line

mc1.swapDepths(2);

mc2.swapDepths(3);



// draw initial line

line_mc.drawLine();



mc1.onPress = mc2.onPress = function()

{

	this.startDrag();

	line_mc.onEnterFrame = drawLine;

}



mc1.onRelease = mc2.onRelease = function()

{

	delete line_mc.onEnterFrame;

	this.stopDrag();

}

How would I go about modifying this code to handle four MCs? I'm imagining something that looks like dragging walls in a room where each MC is a corner of the room. Does that make sense? mc1 connects to mc2 which connects to mc3 which connects to mc4 which connects to mc1 again. Thanks for your help!
