That's easy!

I learnt this from the person named "MISIUR" here on SA-MP Forums :P.

At the top of your script, make a new variable named

pawn Код:

new AlreadySpawned[MAX_PLAYERS] = 0;

Then do in the ZCMD, ...

pawn Код:

CMD:v(playerid, params[])
{
 if(AlreadySpawned[playerid] != 0) return SCM(playerid, -1, "Handle already obtained.");
 vID = CreateVehicle(bla bla bla);
 AlreadySpawned[playerid] = vID;
 PutPlayerInVehicle(playerid, vID, 0);
}

Then if you have like a destroy veh command, just use same thing, again.

pawn Код:

AlreadySpawned[playerid] = 0;

Credit goes to Misiur, for learning me to script PAWNO, in such a way I never did before.

By the way, #define SCM SendClientMessage - I just use that instead of stock SendClientMessage 1000x, easier to type.
