Finite state machine bad argument module?

bigtunacan

I've seen this finite state machine recommended on the forums in the past github.com/cornelisse/LuaFSM/issues

I tried setting up a very basic test usage with it, but it errors out

classes/fsm.lua:139: bad argument #1 to 'module' (string expected, got nil)

Here is my code where I tried to test it out.

FSM = require "fsm"   function action1() print("This is action 1") end   function action2() print("This is action 2") end   function action1() print("This is exceptionAction") end   local stateTransitionTable = { {"state1", "event1", "state2", action1}, {"state2", "event2", "state1", action2}, {"*", "*", "state1", exceptionAction} }   fsm = FSM.new(stateTransitionTable) print("Initial state " .. fsm:get())   fsm:fire("event1")

I'm quite new to Lua, so I'm not sure if this is just something I'm doing wrong?

@bigtunacan Here you are:

By the way, it is very old fsm project, you should find some new project for fsm, like this?

It ended up that the existing FSM module was running into problems with Lua 5.1

I forked and updated it to use the new module style. If anyone is interested it can be found here.

@vitalitymobile; thanks for that info. I didn't see that also until after I had already made my updates, but it could be useful in the future.
