Best way for selecting polygon

Hi guys

Im doing kinda rts game where i need to select multiple units like u do in windows or wherever.

I imagine i have to create a polygon on mouse click and scale it until mouse button is down. After this to get all units colliding with that polygon or something like that.

Is this the way? Any ideas are welcome.

Thanks in advance.

I have this old example lying around, hope it helps:

SelectionBox3.capx

Very nice example. Its all i need.

Cheers
