In this Unity tutorial, we’re going to look at how we can add a collectable that gives the player a period of invincibility.

We’ll cover how to trigger invincibility, manage its duration, and cleanly return the player to a normal state once it expires.

This is the twenty third video in our series showing how to make a full top down 2D shooter game in Unity.
