How to prevent a random event being picked twice?

[ironspider]

Greetings all, so in my pin (a music pin based on the band Lord Huron) you have to complete 8 "song" modes (2 from each of the 4 albums). But I have about 5 or 6 song modes for each album. So, I'm trying to figure out the best way to do this. I started by trying to set integers for the songs during the initial skillshot mode (when the mode starts it plays the "select_way_out_west_1_song_integer" event and then there is a second event_player entry that when "select_way_out_west_1_song_integer" is played it plays "select_way_out_west_2_song_integer") using a random event player that picks one of 5 song numbers and writes that to a variable. And then the second song integer is picked--but for some reason I every once in a while, end up with same integer being picked twice.

I tried using this code on the second integer pick to say "only give this option if the number hasn't already been picked" but it's not working:

random_event_player:
  select_way_out_west_1_song_integer:
    events:
      - way_out_west_song_1_1 #Ends of the Earth
      - way_out_west_song_1_2 #Lonesome Dreams
      - way_out_west_song_1_3 #She Lit a Fire
      - way_out_west_song_1_4 #I Will Be Back One Day
      - way_out_west_song_1_5 #The Man Who Lives Forever
  select_way_out_west_2_song_integer:
    events:
      way_out_west_song_2_1{current_player.way_out_west_1_integer!=1}: 20 #Ends of the Earth
      way_out_west_song_2_2{current_player.way_out_west_1_integer!=2}: 20 #Lonesome Dreams
      way_out_west_song_2_3{current_player.way_out_west_1_integer!=3}: 20 #She Lit a Fire
      way_out_west_song_2_4{current_player.way_out_west_1_integer!=4}: 20 #I Will Be Back One Day
      way_out_west_song_2_5{current_player.way_out_west_1_integer!=5}: 20 #The Man Who Lives Forever

Basically, how do i pick 2 numbers from a list of numbers and make sure that the second number picked is not the same number as the first number picked?

Or is there a better way to do this since I imagine there must be a way that mystery awards don't award the same thing twice? (like extra balls or specials or strobe multiballs, etc.)?

It looks right to me... does it makes any difference if you skip the weight on the events in select_way_out_west_2_song_integer?

Mystery awards example doesn't use two random_events, it use one. If you pick both events from select_way_out_west_1_song_integer and use force_all it should work. But perhaps that destroys something else with your design due to how events are named.

EDIT, I need to read better. :D You use two different "event-pools".

I actually ended up just having one mode that is called that picks one item and random for each of the 4 albums and writes that to a variable and then calls a second mode that uses conditionals to filter out the song that matches the variable from the first mode.

I know there must be a much more elegant way to do it but it does seem to be working.

Gill, I think you had posted a longer post (and then edited it down) about force_all and force_different which actually did help me understand some things about how mystery modes can work so thank you for that!

Great to hear you moved forward.
Yes, I did edit it down a bit, I'm a bit lazy when reading, my English isn't that good so I redid my answer, guess you saw the original answer in a mail from GitHub.

Cheers.
