Raycasts, Explained. Every Physics "Cast" Visualized | Unity Tutorial

Many of us kind of jumped into gamedev without a solid understanding of these Physics APIs such as Raycast and Spherecast. In this video I aim to make it really clear how each of the Ray, Sphere, Box, and Capsule casts work, look, behave, and how you can use each one of them to achieve your "casting" goals!

In this tutorial video you can see the following "casts" visualized:
1. Raycast
2. RaycastAll
3. Spherecast
4. SpherecastAll
5. Boxcast
6. BoxcastAll
7. Capsulecast
8. CapsulecastAll
each with different variations with trigger collision, layer masking, and more!

With 19 customizable scenarios, you know the full project being available on GitHub (https://github.com/llamacademy/raycas...) will help you better understand how to use each of these fundamental gamedev functions!
