kyleconroy / lua-state-machine Goto Github PK

Hi, have the developers tried to add this library to a Defold project as a dependency? I'm able to attach other github releases on Defold, however for some reason this library doesn't load in.

local m = statemachine.create{
    initial = "idle",
    events = {
        {name = "one", from = {"idle", "two"}, to = "one"},
        {name = "two", from = {"one", "idle"}, to = "two"},
        {name = "idle", from = {"one, two"}, to = "idle"},
    }
}
print("idle", m.current)
m:one()
print("one", m.current)
m:idle()
print("idle", m.current)

produces output:

idle    idle
one     one
idle    one

What's going on here? I've tried changing the event names to be different to the states they transition to, but I'm still having this problem.

I have a simple print in my call back and it prints two times. Is this what is supposed to happen? Other than that amazing!

It'd be awesome to have this package on LuaRocks, so that I can depend on it without having to copy files manually...

According to http://www.lua.org/pil/6.3.html lua supports tail calls, and the following example really gives infinite loop

function room1()
    print("Room1")
    return room2()
end

function room2()
    print("Room2")
    return room3()
end

function room3()
    print("Room3")
    return room1()
end

room1()

Yet, direct implementation of this code using lua-state-machine yields stack overflow

local machine = require 'statemachine'

local fsm = machine.create({
    initial = 'room1',

    events = {
        { name = 'go', from = 'room1', to = 'room2' },
        { name = 'go', from = 'room2', to = 'room3' },
        { name = 'go', from = 'room3', to = 'room1' },
    },
    callbacks = {
        onroom1 = function(self, event, from, to) print("Room1"); return self:go() end,
        onroom2 = function(self, event, from, to) print("Room2"); return self:go() end,
        onroom3 = function(self, event, from, to) print("Room3"); return self:go() end,
    }
})

fsm:go()

Well, may be I am not using it properly...

Hi - I plan to use your code in a game mod I'm developing. I'm wondering if you'd consider consuming XState configurations natively? Check out https://xstate.js.org/ and https://stately.ai/viz for examples of state machine configuration code. Let me know if you need more info or context.

Hi!

Can you make an example of the work for the state-machine state hero

1. Stand
2. Move (left, right)
3. Jump on the spot
4. Move to the left and Jump
5. Move to the right and Jump
6. Death

I would have really helped this example to understand the state-machine.
Thank!

The current version, 1.0.0, is three years old.

I check the source code, and can't find anything about 'Asynchronous State Transitions'.

No machine.ASYNC, no machine.transition.

Readme is cheating me.

How can I list possible events from current state?

Just asking if it's possilble to implement a History state, as per https://stately.ai/docs/xstate-v5/history-states
