Hitscan Guns with Bullet Tracers | Raycast Shooting Unity Tutorial

Learn how to show bullet trails, aka bullet tracers to your "hitscan" guns that use Raycast. This easy to implement VFX is a great way to show your players where the bullets are going besides just bullet impacts.

In the tutorial you'll learn how to implement a hitscan gun that does not use rigidbody physics, but instead uses a Raycast to determine if the bullet should hit or not. You'll learn how to add in variable bullet spread, show the bullet trail, and play an impact particle system at the location if impact.
