This is the dev documentation for an unreleased 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. Unless you’re specifically looking for this version, you probably want to use the version of documentation called “latest” which is for the latest released version of MPF. That documentation is at docs.missionpinball.org/en/latest.
A game start has been requested, but the ball search process is running and thus the game start has been blocked. This is a good event to use for a slide player to inform the player that the machine is looking for a missing ball.
This event does not have any keyword arguments
