self.machine.drop_target_banks.*

class mpf.devices.drop_target.DropTargetBank(*args, **kwargs)

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

A bank of drop targets in a pinball machine by grouping together multiple DropTarget class devices.

Accessing drop_target_banks in code

The device collection which contains the drop_target_banks in your machine is available via self.machine.drop_target_banks. For example, to access one called “foo”, you would use self.machine.drop_target_banks.foo. You can also access drop_target_banks in dictionary form, e.g. self.machine.drop_target_banks['foo']. You can also get devices by tag or hardware number. See the DeviceCollection documentation for details.

Methods & Attributes

Drop_target_banks have the following methods & attributes available. Note that methods & attributes inherited from base classes are not included here.

enable() → None

Enable handler.

event_enable(**kwargs)

Event handler for enable event.

event_reset(**kwargs)

Handle reset control event.

format_log_line(msg, context, error_no) → str

Return a formatted log line with log link and context.

get_placeholder_value(item)

Get the value of a placeholder.

member_target_change()

Handle that a member drop target has changed state. This method causes this group to update its down and up counts and complete status.

raise_config_error(msg, error_no, *, context=None) → NoReturn

Raise a ConfigFileError exception.

reset()

Reset this bank of drop targets. This method has some intelligence to figure out what coil(s) it should fire. It builds up a set by looking at its own reset_coil and reset_coils settings, and also scanning through all the member drop targets and collecting their coils. Then it pulses each of them. (This coil list is a “set” which means it only sends a single pulse to each coil, even if each drop target is configured with its own coil.)

subscribe_attribute(item, machine)

Subscribe to an attribute.
