Coding your projectile arc

Coding projectiles for your tower defense game — Part 2

In the second part of this series, we will be exploring how to give our projectiles a nice vertical arc as they travel towards the target. This article will expand upon the work in Part 1, where we coded a projectile that could home in onto the target and detect collision with the target without using Unity’s physics engine’s.
