Join the Discord: https://discord.gg/4tHeAkxNg7 In this tutorial, I explain how to check if a line is intersecting with a box. The way that I accomplish this is using a raycasting techinque (you could achieve the same result using variants of clipping algorithms). I extensively explain the mathematics behind this, going over a concrete example of how the raycast works. I explain how we can use the minimum and maximum of an AABB (2D box) to figure out the entry point and exit point of an intersecting line. Then, we implement the method. I also go over how to extend this functionality to check if a line is intersecting with an OBB (2D rotated box).
