[cadz]

hi anyone can help me how to add waiting room in LMS but to shuffle the players before entering? 

Spoiler

OnStart:
    if ( getwaitingroomstate( 0, "red bravery" ) < .minplayer2start || getwaitingroomstate( 0, "blue bavery" ) < .minplayer2start ) end;
    set .red, waitingroom2bg( "bat_c01", 53,128, strnpcinfo(0)+"::OnredQuit", strnpcinfo(0)+"::OnredDead", "red bravery" );
    copyarray .team1aid[.@i], $@arenamembers[.@i], $@arenamembersnum;
    set .blue, waitingroom2bg( "bat_c01", 146,55, strnpcinfo(0)+"::OnblueQuit", strnpcinfo(0)+"::OnblueDead", "blue bavery" );
    copyarray .team2aid[.@i], $@arenamembers[.@i], $@arenamembersnum;
    delwaitingroom "red bravery";
    delwaitingroom "blue bavery";
    bg_warp .red, "bat_c01", 58,123;
    bg_warp .blue, "bat_c01", 141,60;
    set .score[1], .startingscore;
    set .score[2], .startingscore;
    bg_updatescore "bat_c01", .score[1], .score[2];
    sleep .eventlasting * 1000;

 

bat_room,150,156,5    script    red bravery    733,{
    end;
OnInit:
    waitingroom "bravery red side", getvariableofnpc( .minplayer2start, "custom_bg#control" ) +1, "custom_bg#control::OnStart", getvariableofnpc( .minplayer2start, "custom_bg#control" );
    end;
}
bat_room,150,144,5    script    blue bavery    734,{
    end;
OnInit:
    waitingroom "bravery blue side", getvariableofnpc( .minplayer2start, "custom_bg#control" ) +1, "custom_bg#control::OnStart", getvariableofnpc( .minplayer2start, "custom_bg#control" );
    end;
