Question

我收到消息“这个游戏表明它是为了爱的版本'0.9.1'而制作的。它可能与正在运行的版本（0.10.2）不兼容。“当我尝试运行我的游戏时。游戏仍然可以工作，但是这条消息让我烦恼。如何将其更新到最新版本？我的代码在这里： debug = true 的 Main.lua - 计时器

-- We declare these here so we don't have to edit them multiple places
canShoot = true
canShootTimerMax = 0.2 
canShootTimer = canShootTimerMax
createEnemyTimerMax = 0.4
createEnemyTimer = createEnemyTimerMax

-- Player Object
player = { x = 200, y = 710, speed = 150, img = nil }
isAlive = true
score  = 0

-- Image Storage
bulletImg = nil
enemyImg = nil

-- Entity Storage
bullets = {} -- array of current bullets being drawn and updated
enemies = {} -- array of current enemies on screen

-- Collision detection taken function from http://love2d.org/wiki/BoundingBox.lua
-- Returns true if two boxes overlap, false if they don't
-- x1,y1 are the left-top coords of the first box, while w1,h1 are its width and height
-- x2,y2,w2 & h2 are the same, but for the second box
function CheckCollision(x1,y1,w1,h1, x2,y2,w2,h2)
  return x1 < x2+w2 and
         x2 < x1+w1 and
         y1 < y2+h2 and
         y2 < y1+h1
end

-- Loading
function love.load(arg)
    player.img = love.graphics.newImage('assets/plane.png')
    enemyImg = love.graphics.newImage('assets/enemy.png')

end


-- Updating

    -- Time out how far apart our shots can be.
    canShootTimer = canShootTimer - (1 * dt)
    if canShootTimer < 0 then
        canShoot = true
    end

    -- Time out enemy creation
    createEnemyTimer = createEnemyTimer - (1 * dt)
    if createEnemyTimer < 0 then
        createEnemyTimer = createEnemyTimerMax

        randomNumber = math.random(10, love.graphics.getWidth() - 10)
        newEnemy = { x = randomNumber, y = -10, img = enemyImg }
        table.insert(enemies, newEnemy)
    end


    -- update the positions of bullets
    for i, bullet in ipairs(bullets) do

            table.remove(enemies, i)
        end

    -- run our collision detection

正如评论中所述，您的案例中的问题是，在conf.lua中，版本被指定为"0.9.1"。在某些情况下，将此值更改为"0.10.2"就足够了，但在0.9.0和0.10.0之间发生了大量更改。

要特别注意鼠标输入肯定会被破坏，因为在0.10.0之前的版本中，LOVE使用 strings 来表示鼠标按钮，而在0.10.0及更高版本中，使用数字。要解决此问题，请查找与鼠标相关的功能（love.mouse.isDown，love.mousepressed等）并将"l"更改为1，"r"更改为{{1} }，等等。有关详情，请参阅old values和love.mousepressed的完整列表。此外，鼠标滚轮移动也发生了变化，添加了love.wheelmoved回调并删除了传递给2的字符串。

此外，请仔细阅读changelog以了解可能影响您的计划的所有更改。
