|
[AABB] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
|
|
It uses floating-point coordinates. The 2D counterpart to [AABB] is [Rect2].
|
|
Negative values for [member size] are not supported and will not work for most methods. Use [method abs] to get an AABB with a positive size.
|
|
[b]Note:[/b] Unlike [Rect2], [AABB] does not have a variant that uses integer coordinates.
