Create a game start-up menu screen with Lua/love 2d

Question

I just got started programming games and decided to try out love2d since I'm learning lua.

I was wondering if anyone knows how I can create just a simple 2-3 button menu when you start up the game.

All I want to do is make a start up menu.

I have 2 files and nothing else:

• main.lua, in which I have the game code and the level design
• conf.lua, in which I have the title screen code and the icon of the game

I couldn't find any wiki page to help me for coding for the first time a splash screen and a overall game screen !!

now i have only one screen the game screen and i want to have 3 screens : 1 splash screen in wich i want to draw a image background and 3 buttons PLAY,EXIT,TITLE with coding mousepress! 2 game screen! 3 game over screen with an other background image!

Answer 1

There isn't a built-in menu system for love2d. The developers take a 'do-it-yourself' approach to a lot of such things. Here's an example of how I ended up rigging my menu for my first time:

function love.load()
    currentScreen = 'menu'
end

function love.update(dt)
    if currentScreen == 'menu' then
        menuUpdate(dt)
    else
        gameUpdate(dt)
    end
end

function love.draw()
    if currentScreen == 'menu' then
        menuDraw(dt)
    else
        gameDraw(dt)
    end
end

function menuUpdate(dt)
    if love.mouse.isDown(1) then
        local x, y = love.mouse.getX(), love.mouse.getY()
        --check to see if the mouse is within the option box. If it is, set currentScreen to 'game'
    end
end

--all the other stuff(gameUpdate,gameDraw,menuDraw)
