pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if( ( newkeys & KEY_YES ) && !( oldkeys & KEY_YES ) )
    {
        // code...
    }
    return 1;
}

Well.. if you used ZCMD, then it'd be easier. You'd only have to do: cmd_robplace( playerid, "" );

You may be able to do something like:

pawn Код:

CallLocalFunction( "OnPlayerCommandText", "is", playerid, "/robplace" );

though.
