Machine Variables in Code

You can use machine variables by calling into the MPF machine.

# read machine variable

# configure variable to persist to disk and expire after 1 day (optional)
# alternatively you can also use "machine_vars" in config to achieve the same
self.machine.variables.configure_machine_var("my_variable", persist=True, expire_secs=86400)

# set a variable
self.machine.variables.set_machine_var("my_variable", 17)
