Checkpoints

Hello, just wanting to know how do I set checkpoints, since I have a very long runner game I am in the need of checkpoints, please don’t type to me how to do it, please send a screenshot, thanks… Also the checkpoint I am wanting is that once someone hits it, it disappears, further on in the game if they die they respawn where the checkpoint was, even more further there is going to be other checkpoints, and if they die any where in between there then they respawn back to the checkpoints they last hit, thanks if someone helps!
