create selection rectangle
I need to create a selection rectangle on the stage that works as such:
1. Mouse down on stage activates mouse move
2. As the mouse moves, a rectangle is drawn
3. Mouse up highlights all objects that are within the boundaries of the rectangle
I have parts 1 and 2 working fine, but have been unable to think of an effective way to do part 3. All I can think of is to loop through all items on the stage and check if their positions are within the boundaries of the selection rectangle, but that seems really inefficient to me. Does anyone know a better way to do this?
Thanks in advance.
