Bukkit

i would like to see a setting so players have to:

pass any checkpoint in order
a player leaving an checkpoint out dosent make the next checkpoint count for that player, and you cant win untill you have all checkpoints in row done.

a way players have to pass all checkpoints atleast once befor they can win
a player not having passed all checkpoints atleast once cant win unless he passed all checkpoints

best would be a way to show each player what checkpoint is next for him/ what checkpoint he hasent passed so far.

that way i could setup an arena where the player can freely roaming arround obstacles, having to get the quickest way from checkpoint to checkpoint/ or finding the best moving solution to pass all checkpoints in shorstest time.
