This is a snippet that can be used to store rect data so that you dont have to constantly call GetRectCenterX, GetRectMinX, etc.. when registering "Unit enters region" events for a trigger.

Table is an optional requirement and is only used for debugging purposes.

I found it useful for my map, so I thought I'd post it here.

Feel free to comment.

Side Note: Most of it inlines anyways.

Actually, the reason I made it debug only was because if 2 systems were doing that, you'd be prompted while your debugging and fix it ^^

Btw, did you notice how I started using Nestharus' allocation/deallocation methods? :p
I'm never ever going to use normal structs EVER again xD

Update: Optimized CenterX/Y calculation
