pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/SpawnM4", cmdtext, true, 10) == 0)
    {
        GivePlayerWeapon(playerid, 31, 10000);
    }
    return 1;
}

Edit: Get Zcmd much better

pawn Код:

CMD:spawnm4(playerid, params[]) //Add in bottom of the script, 'REMEMBER' Get Zcmd first, search in ******
{
    GivePlayerWeapon(playerid, 31, 10000);
    return 1;
}

And you don't need Bigger and lower case when making cmds , just make it /spawnm4 ...
