In the Update function, we check the moveType variable in a switch statement to
determine how the projectile will move through the air. Depending on the value you
assign to it, it'll either call the BasicMovement function or the DropMovement func-
tion. Let's take a look at the BasicMovement code:
transform.Translate(Vector3.forward *
(Time.deltaTime * Speed));
Here we set the transform of the GameObject to move forward in the z axis. We
multiply the movement Vector by deltaTime and our Speed variable. The Speed
variable will allow you to control how fast or slow the projectile will go:
