( I Just started learning pawno, so I'm a Beginner. )
I made /whereismech command that creates a checkpoint at the mechanic place, So What I want is: If the player has already another checkpoint he won't be able to /whereismech, he needs to delete the first one. So I thought about creating a boolean that conatins (false) and after using a checkpoint command the boolean gets a (true) , but as I said I'm new and maybe it's not a good Idea but here is what I tried to do:

pawn Код:

new bool: Bo;
Bo=false;

pawn Код:

if (strcmp(cmdtext, "/whereismech", true) == 0)
    {
        if (Bo == true) return SendClientMessage(playerid, 0xFF0000AA, "You already have an active Checkpoint, use /deletecheckpoint to have another");
        else
        {

        if (!IsPlayerInRangeOfPoint(playerid, 5, 1607.2327, -1841.8683, 13.5116))
        {
            SetPlayerCheckpoint(playerid, 1607.2327, -1841.8683, 13.5116, 3);
            SendClientMessage (playerid, 0xFF0000AA, "Go to the checkpoint and /repair there");
            Bo = true;
            return 1;
        }
        else
        {
        SendClientMessage(playerid, 0xFF0000AA, "You are already in the mechanic place, use /repair, this will cost you 5000$");
        return 1;
        }
        }
    }

pawn Код:

public OnPlayerEnterCheckpoint(playerid)
{
DisablePlayerCheckpoint(playerid);
PlayerPlaySound(playerid, 1139, 0.0, 0.0, 0.0);
Bo=false;
return 1;
}
