#include <a_samp>
#pragma tabsize 0
#define xz
#define DIALOGID 10

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/music", cmdtext, true) == 0)
    {
if(dialogid == xz){
if(response){
if(listitem == 0){
new String[7700];
    strins(String,"Екстра FM\r\n",strlen(String));
    strins(String,"Хит FM\r\n",strlen(String));
    strins(String,"Выключить\r\n",strlen(String));
ShowPlayerDialog(playerid,xz,DIALOG_STYLE_LIST,"Онлайн радио",String,"Выбрать","Отмена");
}}
return 1;}
if(dialogid == xz){
if(response){
if(listitem == 0)  {PlayAudioStreamForPlayer(playerid, "http://live.ekstra-fm.ru:8001/efm");}
if(listitem == 1)  {PlayAudioStreamForPlayer(playerid, "http://radio.i.ua/play/hit.fm/");}
if(listitem == 2)  {StopAudioStreamForPlayer(playerid);}
return 1;}
        return true;
    }
    return false;
}
