RegionClearRect

Parameters

whichRegion	region	The region to be modified.
r	rect	The rect whose cells to remove.

comment

Removes the cells of a rect from a region.

note

Cells are 32x32 world units and aligned with multiples of 32 in each direction (smallest grid in World Editor).

note

The current cells of the rect are removed. Changing the rect afterwards has no effect on the region.

bug

An extra row and column of cells in positive x and y direction is removed. E.g., if the rect is [minX=0, minY=0, maxX=96, maxY=96], the region will lose cells spanning the area [minX=0, minY=0, maxX=128, maxY=128]. This is reflected in IsPointInRegion, IsUnitInRegion, TriggerRegisterEnterRegion and TriggerRegisterLeaveRegion.
