Like this:

pawn Код:

new bool:pSpawn[MAX_PLAYERS];

public OnPlayerConnect(playerid)
{
    pSpawn[playerid] = false;
    return 1;
}

public OnPlayerSpawn(playerid)
{
    pSpawn[playerid] = true;
    return 1;
}

And you use this to check if he spawned:

pawn Код:

if(!pSpawn[playerid]) return SendClientMessage(playerid, -1, "ERROR: You must Spawn to use this command.");
