The type is not the playerid but a race checkpoint with the finish type, none, arrows, air etc.

You can either create all the checkpoints (store the IDs) and use TogglePlayerDynamicRaceCP function:

pawn Код:

native TogglePlayerDynamicRaceCP(playerid, checkpointid, toggle);

to toggle them

OR

create one race checkpoint and when the player does what you want, disable it.
