I have a script as follows:

Code:

CMD:th(playerid, params[])
{
	for(new vid; vid<MAX_VEHICLES; vid++) 
	{
		new Float:vx, Float:vy, Float:vz;
		GetVehiclePos(vid,vx,vy,vz);  
		GetXYBehindCar(vid,vx,vy,3.5);
		if(IsPlayerInRangeOfPoint(playerid,2.5,vx,vy,vz))
		{
			CarPack = GetPlayerVehicleID(playerid)
			if(IsThueXeVehicle(vid))
			{
				if(PackCar[vid] == 5) return SendClientMessage(playerid, COLOR_LIGHTRED, "SERVER: Xe nay da bo du so hang.");
				SetPlayerSpecialAction(playerid,0); 
				ClearAnimations(playerid);
				ApplyAnimation(playerid, "CARRY", "crry_prtial", 4.0, 0, 0, 0, 0, 1);
				RemovePlayerAttachedObject(playerid,0);
				PackCar[CarPack]++;
				LayPack = PackCar[vid];
				PlayerInfo[playerid][pPackTruonghop] = 0; 
				if(PackCar[vid] == 1)
				{
					Vehicle[playerid][0] = CreateObject(1220,0,0,-1000,0,0,0,100);
					AttachObjectToVehicle(Vehicle[playerid][0], vid, 0.450000,-1.049999,0.300000,0.000000,0.000000,0.000000);
					return 1; 
				}
				if(PackCar[vid] == 2)
				{ 
				 	Vehicle[playerid][1] = CreateObject(1220,0,0,-1000,0,0,0,1);
					AttachObjectToVehicle(Vehicle[playerid][1], vid, -0.449999,-1.049999,0.300000,0.000000,0.000000,89.099983);
					return 1;
			    }
				if(PackCar[vid] == 3)
			    {
					Vehicle[playerid][2] = CreateObject(1220,0,0,-1000,0,0,0,100);
					AttachObjectToVehicle(Vehicle[playerid][2], vid, -0.449999,-1.950000,0.300000,0.000000,0.000000,-67.500007);
					return 1;
			    }
				if(PackCar[vid] == 4)
			    {
			    	Vehicle[playerid][3] = CreateObject(1220,0,0,-1000,0,0,0,100);
					AttachObjectToVehicle(Vehicle[playerid][3], vid, 0.450000,-1.950000,0.300000,0.000000,0.000000,97.199974);
					return 1;
			    }
				if(PackCar[vid] == 5)
				{
					Vehicle[playerid][4] = CreateObject(1220,0,0,-1000,0,0,0,100);
					AttachObjectToVehicle(Vehicle[playerid][4], vid, -0.0
					
					
					
(......)

And I need to use variable Packcar[vid] outsize a CMD:th{}. But it don't work. I am a Pawno Beginner. Plz help me solve this problem. Thanks.

I want to use it in OnPlayerChangeState. But I get the error: error 017: undefined symbol "vid"
... sr for my bad english.

Thanks, I will learn the basics later. But you don't understand me. I want to use vid's value of CMD:th{} in OnPlayerChangeState. If I declare "vid" in that callback too, vid's value in OnPlayerChangeState will different from vid's value in CMD:th{}. Sorry, Can you guide me? I really need it right now.

Sorry if I disturb you. I will learn right now, but what I should learn first(in Basic Script)?

variable that you declared is local variable, which is only usable in your command. If you want to use variables in commands and other callbacks, you will need to use global variables, which you will have to declare on the top of the script because you want it to be "known" in all script
