Mission Pinball Framework

VPE connects to MPF using gRPC, which is a high-performance, low-latency RPC framework. It works by VPE launching MPF as a Python process. MPF will then spawn a gRPC server, to which VPE connects to.

There are two situations when this is done:

• In edit mode to retrieve available switches, coils and lamps
• During runtime to drive the game

VPE supports MPF's hardware rules, which are dynamic connections between coils and switches handled by the controller boards in order to reduce latency. The media controller is not yet supported.
