This is an MPF Event
The content on this page is technical documentation for an MPF Event.
Posted when a machine variable is added or changes value. (Machine variables are like player variables, except they're maintained machine-wide instead of per-player or per-game.)
(See the Conditional Events guide for details for how to create entries in your config file that only respond to certain combinations of the arguments below.)
: If the machine variable just changed, this will be the amount of the change. If it's not possible to determine a numeric change (for example, if this machine variable is a list), then this change value will be set to the boolean True.
: The previous value of this machine variable, e.g. what it was before the current value.
: The new value of this machine variable.
