I'm not using a sprite, I'm using a box. I want to position objects in relation to the box without needing to do any calculations based on its size. Rather than pre-calculating all of the x/y values, I just want to do 'box.x+2, box.y+2' and have the item spawn two pixels in from the top-left corner.
I'm using the 'System - create relative to object' action, but the pivot point is always in the centre and I need to spawn things relative to the corner. That's why I made this request.
Also, not in this case, but maybe in others, it may be necessary to rotate something not around the centre, like you can do in Flash.
Am I just trying to use the box object in a way it wasn't intended here?
