* struct RectData : array

* - This destroys an instance of the struct

endmethod
debug implement Init
endstruct
endlibraryThis 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.
