Well this is an example of a 2 button message box.

To show it:

pawn Код:

ShowPlayerDialog(playerid,1,DIALOG_STYLE_MSGBOX,"Dialog title","This is a new feature!\nCool, isn't it?","Yes","No");

Under the OnDialogResponse callback:

pawn Код:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
  if(dialogid == 1) // The dialog ID we assigned the message box to
  {
    if(response) SendClientMessage(playerid, 0xFFFFFFFF, "Yes? Me too!"); // If they clicked Yes
    else SendClientMessage(playerid, 0xFFFFFFFF, "No? Well I think it's cool."); // If they cliked no
  }
  return 1;
}

If you need help with lists or input boxes, just ask.
