In this Unity tutorial we're going to look at how we can make the player jump!

First of all, we'll look at how to setup the input action to trigger the jump. Then, we’ll apply an upward velocity to the Rigidbody to make it happen.

By the end of this video, you’ll have a simple and effective jump mechanic for your 3D platformer.

This is the fourth video in our series showing how to make a full 3D platformer game in Unity.
