FSM undo transition #7

Closed AlecTroemel closed 4 years ago

AlecTroemel commented 4 years ago

The right way to do this is to extend FSM like this implementation https://github.com/davidchin/switchhub 1.a history field that tracks actions taken (along with parameters)

undoTransition that pops the last item in history, and goes the other way.
onundo_EVENT callbacks

this could then be backported to https://github.com/kyleconroy/lua-state-machine

[x] fsm storing history
[x] fsm undoTransition function
[x] undo add
[x] undo move
- [x] figure out how to store the "army" state
[x] undo push
[x] undo stone removals as a result of "life/death" rule. Need to find a way to store the "removed stones" as a result of an action on the history stack

this probably depends on https://github.com/AlecTroemel/phallanx/issues/11
