Assuming you have DCMD and SSCANF defined:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    dcmd(command, 7, cmdtext);
    return 0;
}
    
dcmd_command(playerid, params[])
{
    new
        name[MAX_PLAYER_NAME],
        string[128];
    if (sscanf(params, "s", string)) SendClientMessage(playerid, 0xFF0000AA, "Usage: \"/command <string>\"");
    else
    {
        GetPlayerName(playerid, name, sizeof(name));
        format(string, sizeof(string), "%s typed: %s", name, string);
        SendClientMessageToAll(0xFF00FFFF, string);
    }
    return 1;
}

Indentation fixed, curse you pawn box!

EDIT: Not sure about getting tied down in projects, I mean, I've been helping people here for ages now anyway...
