Projectile Trajectory with Simple Math & Line Renderer | Unity Tutorial

Need to show the path of a projectile? Not paying attention in Physics catching up to you? No problem! Learn how to draw the trajectory of a projectile would take using a LineRenderer and one of those pesky physics formulas you said you'd never use again! Show a visualization of where those objects will go!

We're using a grenade in this case, but it can be applied to cannon balls, bullets affected by gravity, throwing a banana, or any other projectile!

If you're checking out the GitHub Repository below, make sure to get the Unity Particle Pack and head over to Mixamo and pick up the "Throw Object" animation (tip: trim it down to skip the pick-up section) and add it to the Animator with an upper body avatar mask.
