Ever wanted a Title Screen or a Menu?
This guide can show you how to manage multiple states at the same time!
Note: For examplatory purposes, we'll be using the prefixes "game" and "title" for this tutorial.
The function "_init()" is what happens when the game is started up (or in this case, the State).
function _init() titleinit() -- does title things. end function titleinit() mode = 0 --whatever you wish to do when the title starts up. end function gameinit() mode = 1 --what to do at the start of the play session. end
We'll call on gameinit() later.
The function "_update()" is where gameplay elements are changed (like a timer).
function _update() if (mode == 0) then --Title Screen mode titleupdate() else gameupdate() end end function titleupdate() --Example "Press Z to start" --if btn(4,0) then -- gameinit() --end end function gameupdate() --gameplay elements (or whatever used to be in _update) goes here. end
The example given can be used by simply getting rid of the dashes (or rather uncommenting it).
The function "_draw()" is called to draw things to the screen. (There's some repetition in this one.)
function _draw() if (mode == 0) then --Title Screen mode titledraw() else gamedraw() end end function titledraw() --Example "Title" --print("Super Cool Game") end function gamedraw() --the screen drawing mechanisms(or whatever used to be in _draw) goes here. end
- If you want to add more to "_draw" or "_update", simply follow this guideline:
else if (mode == 2) then --optiondraw() or optionupdate()
just be sure to put that before the else statement!
