Achievement groups are used to group together individual achievements.
If you look at the real-world examples we used in the achievements documentation, each of the entries in that list is an achievement “group” that’s made up of individual achievements.
For example, in The Addams Family, the mansion awards would be individual achievements, for example:
- 9 Mil
- 6 Mil
- 3 Mil
- Quick Multiball
- Grave Yard at Max
- Raise the Dead
Each of those individual achievements has a state (enabled, started, completed, etc.)
If you were building a config for The Addams Family (TAF) with MPF, you would create an achievement group called “Mansion Awards”, and then you would add the individual achievements to that group.
The achievement group will let you perform group-level actions on the achievements in the group. For example:
- Randomly select one of the incomplete achievements (so you can flash that achievement’s light to indicate it’s selected).
- Change which achievement is selected. (In TAF, each hit to a pop bumper changes the lit achievement, so you’d configure your achievement group to pick a new achievement when the pop bumper hit event was posted.)
- Post an event when all achievements are complete (to start a wizard mode, etc.)
- Post a “start” event for whichever achievement is lit (In TAF, you shoot the lit electric chair or the swamp to start the flashing achievement.)
- Boolean (true/false) as to whether this achievement group is enabled.
- The achievement in the group that is currently in the selected state, or None if no achievement is selected.
