Unit a3dge.Collisions
Uses Types Constants Variables
Description
Implements routines used to check collisions.
These routines are for internal use. It's unlikely you'll need to use them in your games.
Some of these functions references to AABB (Axis-Aligned Bounding Box). This is an special bounding box that is aligned to the coordinate axis. To know more visit this wikipedia article.
