[Rect2] consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
2020-09-21 20:27:50 +08:00
It uses floating-point coordinates. If you need integer coordinates, use [Rect2i] instead.
The 3D counterpart to [Rect2] is [AABB].
2020-04-06 16:34:18 +08:00
Negative values for [member size] are not supported and will not work for most methods. Use [method abs] to get a Rect2 with a positive size.
