How to add rolling to the platformer controls in Unity

Let’s go over how to add rolling to the platformer project.

I am continuing to build on the Player script from this article. The roll animation is from mixamo.com.

Open the Player script. Add a coroutine called Roll. The coroutine will shrink the collider on the Character Controller and also move it to a lower position. Yield for one second and then reset the collider’s size and position:

Inside the PlayerMovement function check for the input from the Shift key and if the player is on the ground, call the coroutine and set the animation trigger:

Lastly, add the animation to the animator controller and set transitions:

Good luck!
