In this lesson, you will learn how to add checkpoints to a 2D game in Unity. These checkpoints will be used to save a player’s progress and update the player’s respawn point. Implementing this involves two steps:

• Add checkpoints throughout a scene (using tagged empty GameObjects)

• Write C# code that checks for player collision with checkpoint colliders and updates the respawn point

The code to implement the respawn checkpoints will be added to an existing script we have worked on throughout this course called ‘PlayerController.cs’ (scroll down for the sample code).
