How to make Checkpoint in Unity?

Question

Mobile development

Hello!
I want to implement the Checkpoint system in a Unity2D project. It is necessary that when the Player enters the Checkpoint's coverage area, the player's position is saved and when the scene is reloaded, the player appears at the position that the Checkpoint saved. There are guides on this topic on YouTube, but not one of them works in my project.
PS Does the save system depend on the player's script or not?
Thanks in advance!

Answer 1

You make an empty object with a trigger collider, throw a script on it, in which ontriggerenter2d checks whether it is a player and already through other.getcomponen().SetCheckpoint(transform.position) you set the player’s position

Answer 2

to save position use https://docs.unity3d.com/ScriptReference/PlayerPre...
transform.position convert to json string and save it PlayerPrefs.SetString
