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!
