Function Documentation

createAreaAABB()

std::unique_ptr<AABB> createAreaAABB	(	AABB *	aabb,
		const int	x,
		const int	y,
		const int	xsize,
		const int	ysize,
		const MapAABBData &	input,
		bool	burgerFlip
	)

Recursively creates an AABB tree for a single area.

Parameters

aabb	The parent AABB. If this is the root AABB, then this is nullptr.
x	The min x coordinate of the area.
y	The min y coordinate of the area.
xsize	The width of the area.
ysize	The height of the area.
input	The input data for the AABB tree.
burgerFlip	Used to change the direction during recursion.

Returns

The root AABB of the area
