Learn how to make your guns shoot projectile / Rigidbody bullets instead of only Raycasts / Hitscan!
We'll look at how to shoot "real" bullets instead of only showing the trail renderer along a path so you can have more complex bullet physics including drag and bullet drop. We'll also see how to prevent a Rigidbody bullet from "teleporting" through objects when moving at high velocities!
Since this is part 6 of the Gun Series, if you're just now jumping in it might be a little confusing. You can watch from the beginning to see how and why each line of code exists here starting from part 1: youtube.com/watch?v=E-vIMamyORg&list=PLllNmP7eq6TQJjgKJ6FKcNFfRREe_L6to
