This is the documentation the latest work-in-progress version of MPF!
This is the documentation for MPF 0.56, which is the “dev” (next) release of MPF that is a work-in-progress. This is probably ok, and means you’ll be on the latest, cutting-edge version of MPF.
However, if you want a more stable version, select the
v:stableversion from the lower-left corner of this page, which is the most recent version that is not getting new updates.
If you are new to MPF, we have recently rewritten the installation process which only applies to this “latest” 0.56, so you probably want to stay here because the prior installation process doesn’t work on the latest OS and Python versions.
Posted when a new ball starts and is ready to be physically ejected to the playfield.
This is a relay event.
(See the Conditional Events guide for details for how to create entries in your config file that only respond to certain combinations of the arguments below.)
- The name of the ball_device target where the ball will be ejected to. Can be modified by a relay event handler to change the target before the ball is ejected.
