I made an obby.

[leaden leaf]

Can someone help me make saving checkpoints?
(Should i use datastoreservice?)

We are here to help you, not giving you the full script, but to your question, yes, you should.

just create a part that its a checkpoint and check for touched event, and save player checkpoint to the position of checkpoint. Also add Y to +1 or +2,

@placid sphinx should i use a checkpoint block, or just a part that has ascript to spawn there?

like the roblox spawnpoint

[placid sphinx]

both works, but disable spawnpoint if you mean checkpoint block as spawnpoint?

disable the Behavior -> Enabled, else player spawn random one of Spawnpoint
