hchello, i am new there and to the programing at all.
I'd like to start from gamedev and from lua and now from LOVE -_-
first wat i need is to make FSM code for my 1st game, kinda state for main menu, play|pause screens, and some UI.
I need any help.
For now i'm readyng wiki and looking the code of games. Maybe someone know there exactly i should look? any help will be usefull

Re: FSM - Finite State Machine
vrld's HUMP has a gamestate module, maybe that is what you're looking for?

Re: FSM - Finite State Machine
Hmm... Maybe we should gather a list of Lua and Love documentation and tutorials and stuff, and make a stickied thread?

Re: FSM - Finite State Machine
I am currently using boolean flags. For everything. Everytime I am going to draw I ask if it's the gamestart menu, the settings menu, the playing scene or whatever. And the same for the input. I should definately take a look at this FMS thing xD

Re: FSM - Finite State Machine
I decided not use any 3rd party State Library since I found that this simple routine used for love.draw and love.update worked so well enough. Why complicate more?Ellohir wrote:I am currently using boolean flags. For everything. Everytime I am going to draw I ask if it's the gamestart menu, the settings menu, the playing scene or whatever.

(love draw variation here)
Code: Select all
if(game_state == 'nullState') then drawNull()
elseif(game_state == 'introState') then drawIntro()
elseif(game_state == 'selectState') then drawSelect()
elseif(game_state == 'playState') then drawPlay()
elseif(game_state == 'editState') then drawEdit()
elseif(game_state == 'deadState' or game_state == "goalState") then drawDebriefing()
elseif(game_state == 'helpState') then drawHelp()
elseif(game_state == 'pauseState') then drawPause()
elseif(game_state == 'quitState') then drawQuit()
else error('game_state is not valid')
end
Did you worked in LUA variant? Last time I checked the Lua docs for Polygamy were rare (or non-existent)Dilli wrote:For gamestate management I love Pölygamy

I'd use a table here, it's simpler to extend:coffee wrote:I decided not use any 3rd party State Library since I found that this simple routine used for love.draw and love.update worked so well enough. Why complicate more?
Code: Select all
game_states = {nullState = drawNull, introState = drawIntro, selectState = drawSelect, ... }
-- in love.draw
game_states[game_state]()

Re: FSM - Finite State Machine
Thank you for the clever suggestion Robin. It would be a pleasure implant that but this way rises a problem because it screws the update routine since that I can't redirect the game_state to both sides at same time (draw/update).Robin wrote:I'd use a table here, it's simpler to extend:coffee wrote:I decided not use any 3rd party State Library since I found that this simple routine used for love.draw and love.update worked so well enough.

Re: FSM - Finite State Machine
Seems like you are overcomplicating things. This is good news though. right?
Press space to change gamestate.
Added a metatable default state to clean it up a bit. Only override the functions you want to this way.

Code: Select all
local current_state
local game_states = {
introState = {
draw = function() love.graphics.print("INTRO!!",0,0) end,

keypressed = function(key) if key == " " then current_state = "selectState" end end },
selectState = {
draw = function() love.graphics.print("SELECT!",0,0) end,
update = function(dt) end,
keypressed = function(key) end}
}
function love.load()
current_state = "introState" --or 1,2,...,#game_states
end
function love.update(dt)
game_states[current_state].update(dt)
end
function love.draw()
game_states[current_state].draw()

setmetatable(introState, {__index = defaultState})
game_states["introState"] = introState
