How to use machine variables with segment_display_player?

[kaydeeH]

Hi again,

Hopefully this one is a touch easier than my usual post... On MPF 0.57.3, MPF-MC 0.57.1. I'm trying a simpler approach to how I've done things in the past and, while in attract, I want to write the last game's scores to the segment_display_player. I've tried all of the following:

segment_display_player:
  timer_display_loop_timer_tick{ticks==0}:
    display1:
      text: "{player1_score:d}"

segment_display_player:
  timer_display_loop_timer_tick{ticks==0}:
    display1:
      text: "{machine|player1_score:d}"

segment_display_player:
  timer_display_loop_timer_tick{ticks==0}:
    display1:
      text: (player1_score)

segment_display_player:
  timer_display_loop_timer_tick{ticks==0}:
    display1:
      text: (machine|player1_score)

I have confirmed that the variable is available and populated in the machine_vars file by that name, and I also see it listed on the terminal screen under machine variables when the game is running, and I can see the expected value.

When using the () formats, it just writes the literal string "score)" to the displays. When I use the {} formats, it crashes and the log reports the following:

ValueError: Missing variable player1_score

In other places, I do things like the following and it works great:

player_score{player_num==1}:
  display1:
    text: "{players[0].score:d}"

So I'm not sure what I'm missing here. I'm clearly not calling out the variable the way it wants me to.

Thanks in advance,

Kaydee

Probably not "players" score since no game is running.

My attract does the same, try this

"{machine.score1_value:d}"

Sorry, I replied too quick. I have this which is last player score "{(machine.player1_score):d}"

my reply above is for high score.. sorry about that.

Thank you so much, I'll give this a whirl and report back to close the loop. :)

That worked! Thank you so much.

Follow on question... when there is no last game score for a player (say there wasn't a player 4 in the last game), it writes "0" to the display. what's the best way to say:

if {(machine.player1_score):d} == 0 then "" else {(machine.player1_score):d}

It may be even simpler than that like a boolean operation in the event conditional... I'm sure it's something obvious I'm overlooking, but I'm going cross-eyed at this point, so any tips would be appreciated. Thanks in advance!
