Segment Display Transitions

When MPF switches the current text on a segment display with another text entry, a transition effect can be set that controls what text transition between the new and existing text looks like. You can use these transitions with the Segment Display player and within shows. You can set transitions as a property of the new text entry that comes in, or as a property of the outgoing transition when the current text entry is removed (incoming transitions always take precedence over outgoing transitions).

Here's a list of all the types of segment display text transitions that MPF supports.

none

Setting a transition type of none means that no transition will be used, and the incoming text instantly replaces the current text.

push

The push transition means that the incoming text "pushes" the outgoing text out of the way. (e.g. the outgoing text moves out while the incoming text moves in)

Options for the push transition:

  • direction: left or right (defaults to right).
  • text: An optional text string that is inserted between the old and new text during the transition. Defaults to empty.
  • text_colors: The color for each character in the optional transition text string (if the platform supports it). If a single color is supplied, all characters in the transition text string will be set to that color. See Specifying Colors in Config Files for more information on specifying colors in config files.

cover

The cover transition means that the incoming text moves in on top of to cover the current text. The outgoing text is not animated.

Options for the cover transition:

  • direction: left or right (defaults to right).
  • text: An optional text string that is inserted between the old and new text during the transition. Defaults to empty.
  • text_colors: The color for each character in the optional transition text string (if the platform supports it). If a single color is supplied, all characters in the transition text string will be set to that color. See Specifying Colors in Config Files for more information on specifying colors in config files.

uncover

The uncover transition means that the current text is moved out to uncover the new incoming text.

Options for the uncover transition:

  • direction: left or right (defaults to right).
  • text: An optional text string that is inserted between the old and new text during the transition. Defaults to empty.
  • text_colors: The color for each character in the optional transition text string (if the platform supports it). If a single color is supplied, all characters in the transition text string will be set to that color. See Specifying Colors in Config Files for more information on specifying colors in config files.

wipe

The wipe transition means that the display text is wiped/switched from the current text to the incoming text.

Options for the wipe transition:

  • direction: left or right (defaults to right).
  • text: An optional text string that is inserted between the old and new text during the transition. Defaults to empty.
  • text_colors: The color for each character in the optional transition text string (if the platform supports it). If a single color is supplied, all characters in the transition text string will be set to that color. See Specifying Colors in Config Files for more information on specifying colors in config files.

split

The split transition means that the text is split and either moved in or out to reveal the other text value.

Options for the split transition:

  • mode: push or wipe (defaults to push).
  • direction: in or out (defaults to out).

Configuring Transitions

Transitions are specified as an additional property of a segment_display_player: config or the segment_displays: section of a show config. For example:

#! segment_displays:
#!   display1:
#!     number: 1
segment_display_player:
  jackpot_completed:
    display1:
      text: JACKPOT
      priority: 1000
      expire: 2s
      transition:
        type: push
        direction: right
        text: " *** "
      transition_out:
        type: push
        direction: right
        text: " *** "

When the event "jackpot_completed" occurs, MPF will update the text in the segment display called "display1" using the push transition. After 2 seconds, the "JACKPOT" text will expire and be removed, pushing the text out to the right, restoring the previous text.

Note

If the current text has a transition_out: setting, and the new text has a transition: setting, then the new text's transition setting will take precedence.
