pawn Code:

new tCP[30];
new iCP[30];

Example Code:

pawn Code:

public OnPlayerEnterDynamicCP(playerid, checkpointid)
{
  if(checkpointid == CP[UnityStation])
   {
     if(tCP[UnityStation] == gTeam[playerid]) return SendClientMessage(playerid, COLOR_RED,"This zone is already captured by your team");
     if(UnderAttack[UnityStation] == 1) return SendClientMessage(playerid, COLOR_RED,"This zone is already being taken over!");
     UnderAttack[UnityStation] = 1;
     timer[playerid][UnityStation] = SetTimerEx("CaptureZone",30000,false,"i", playerid);
     SendClientMessage(playerid, COLOR_YELLOW,"You're Capturing this zone! Wait here for 30 Seconds!");
     new string[128];
     format(string, sizeof(string),"[ATTENTION]: Unity Station is Being taken Over!");
     SendClientMessageToAll(COLOR_RED,string);
     iCP[playerid] = UnityStation;
   }
