OnPlayerEnterDynamicRaceCP
#1

My race system works fine when only 1 player is in the race, but whenever a race starts with more than 1 racer, the checkpoints bug out and the players can't trigger them. Sometimes it only bugs out for one person (usually the racer who joined last), but sometimes it bugs out for all racers.

Here's my code: (sorry it's so long and the indentation has been messed up by the forum)
Код:
public OnPlayerEnterDynamicRaceCP(playerid, checkpointid)
{
	if(checkpointid == PlayerRaceCP[playerid]) //If player enters their race checkpoint
	{
	    if(RaceBegun == 1 && InRace[playerid] == 1) //Check if the race has started and the player is in the race
	    {
	        DestroyDynamic3DTextLabel(RacePickupLabels[playerid]); //Destroy a label which informs of vehicle-spawning checkpoints

	        if(RaceCheckpointsType[PlayerCheckpoint[playerid]] == 0) //If the checkpoint type is 0 (on-foot trigger)
	        {
	            DestroyVehicle(GetPlayerVehicleID(playerid)); //Destroy player's vehicle
	            SendClientMessage(playerid, -1, C_RACE"Continue on-foot!"); //Tell them to continue on-foot
			}
			else if(RaceCheckpointsType[PlayerCheckpoint[playerid]] > 1) //If type is higher than 1 (a vehicle ID) (vehicle spawner)
			{
			    format(strang, sizeof(strang), "%d", RaceCheckpointsType[PlayerCheckpoint[playerid]]);
			    cmd_vrace(playerid, strang); //spawn the type's vehicle
			}

			if(RaceCheckpointsType[PlayerCheckpoint[playerid]+1] == 0) //if the next checkpoint's type is 0, add a textlabel saying so
			{
				RacePickupLabels[playerid] = CreateDynamic3DTextLabel("On-foot!", 0xFFFFFFFF, RaceCheckpoints[PlayerCheckpoint[playerid]+1][0], RaceCheckpoints[PlayerCheckpoint[playerid]+1][1], RaceCheckpoints[PlayerCheckpoint[playerid]+1][2], 500.0);
			}
			else if(RaceCheckpointsType[PlayerCheckpoint[playerid]+1] > 1) //and the same for vehicle spawning checkpoints
			{
			    format(strang, sizeof(strang), "%s!", aVehicleNames[RaceCheckpointsType[PlayerCheckpoint[playerid]+1] - 400]);
			    RacePickupLabels[playerid] = CreateDynamic3DTextLabel(strang, 0xFFFFFFFF, RaceCheckpoints[PlayerCheckpoint[playerid]+1][0], RaceCheckpoints[PlayerCheckpoint[playerid]+1][1], RaceCheckpoints[PlayerCheckpoint[playerid]+1][2], 500.0);
			}
			
			PlayerPlaySound(playerid, 1056, 0, 0, 0); //play the checkpoint sound
	    	PlayerCheckpoint[playerid] ++; //add one to the player's checkpoint progress
	        DestroyDynamicRaceCP(PlayerRaceCP[playerid]); //Destroy the CP they just went through

	        if(PlayerCheckpoint[playerid] == checkpointamount+1) //If the checkpoint is the finish
	        {
         		SetPlayerVirtualWorld(playerid, 0); //Send them back to the real world
	            SetVehicleVirtualWorld(GetPlayerVehicleID(playerid), 0); //along with their vehicle
	            InRace[playerid] = 0; //Set the player out of the race
	            Racers --; //Take racers down by one
	            
	            //REMOVED UNRELATED CODE
			}
			else
			{
			    if(PlayerCheckpoint[playerid] == checkpointamount) //If player's checkpoint is second from last
			    {
			    	PlayerRaceCP[playerid] = CreatePlayerRaceCP(playerid, 1); //create FINISH LINE checkpoint
				}
				else
				{
				    PlayerRaceCP[playerid] = CreatePlayerRaceCP(playerid); //otherwise create a normal checkpoint
				}
			}
		}
	}
	return 1;
}
Also, I have some code on OnPlayerUpdate for triggering the checkpoint while the player is already in it when the race starts, as it wasn't getting triggered at first unless the player drove out and then into the checkpoint again:

pawn Код:
public OnPlayerUpdate(playerid)
{
    if(IsPlayerInDynamicRaceCP(playerid, PlayerRaceCP[playerid]) && InRace[playerid] == 1 && RaceBegun == 1)
    { //If player is in their race CP and they're in the race and the race has started
        if(PlayerRaceCP[playerid] == 1) //If the player's Race checkpoint is the first one
        {
            PlayerPlaySound(playerid, 4202, 0, 0, 0); //play sound
           
            PlayerCheckpoint[playerid] ++; //Add to progress
           
            DestroyDynamicRaceCP(PlayerRaceCP[playerid]); //Destroy checkpoint they just went through
           
            PlayerRaceCP[playerid] = CreatePlayerRaceCP(playerid); //Create next checkpoint
        }
    }
    return 1;
}

If you're bugged, no matter how many times you enter the checkpoint, you cannot trigger it. Does anyone have any ideas of what could be causing this, or has anyone else experienced this? Is it because two players enter the checkpoint together in such a short timespan so the script can't process it properly?

I also have a Goldpot system that uses normal dynamic checkpoints, but I've tried to disable these in case they were conflicting but to no avail.

EDIT: It also seems my /leave command is interfering with other players; when a player /leaves a race, it removes checkpoints for all players in the race.
