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.
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¶
Event handler for enable event.
Handle reset control event.
format_log_line(msg, context, error_no) → str¶
Return a formatted log line with log link and context.
Get the value of a placeholder.
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¶

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.)
