self.machine.ball_holds.*

class mpf.devices.ball_hold.BallHold(self_inner, *args, **kwargs)

Bases: mpf.core.system_wide_device.SystemWideDevice, mpf.core.mode_device.ModeDevice

Ball hold device which can be used to keep balls in ball devices and control their eject later on.

Accessing ball_holds in code

The device collection which contains the ball_holds in your machine is available via self.machine.ball_holds. For example, to access one called "foo", you would use self.machine.ball_holds.foo. You can also access ball_holds in dictionary form, e.g. self.machine.ball_holds['foo'].

You can also get devices by tag or hardware number. See the DeviceCollection documentation for details.
