basically you store each check point in a aray and as each player can only have one cp active you need to loop through at aray to see if any are closer then the one currently shown and if there is, disable the old one and show the new one and if it is that same one that is closest just continue

i streamer maybe the way to go if you want a easy checkpoint system

im also a kiwi btw so if you want a hand just pm me ill be on most days
