Well i would suggest this

pawn Код:

forward NearObject(playerid);
new MultipleObjects[MAX_PLAYERS];

pawn Код:

if (strcmp("/race", cmdtext,true, 10) == 0)
 {

  CreateObject(coords);
  racecheckpoint[playerid] = 1;
  return 1;
 }

Then make a new public

pawn Код:

public NearObject(playerid)

{
   DestroyObject(objectid);
   if(MultipleObjects[playerid] == 1)
   {
     CreateObject(next object coords);
     MultipleObjects[playerid] = 2; // NEXT Object
     
   }
   return 1;
}

This is untested , just made this as i read the post xD .......
