You don't add checkpoints using AddPlayerClass ...
If only checkpoint sequences were that easy to create... You need to keep track of the player's current progress through the sequence. Each time the player enters a checkpoint the progress is incremented and a new checkpoint is shown based on that value. Look up a tutorial on how to make a race. It's a similar process. I don't fancy explaining the whole thing here.
