如何更改love2d代码以适应corona sdk（两者都使用lua语言）

我使用love2d框架创建了一个游戏，现在我想将它转移到corona sdk。不幸的是，我收到了一个错误，因为corona不支持love函数。如何纠正这一点？谢谢

main.lua（基本上是love.something函数抛出错误，如本页底部所示）

菜单

-- load variables/menu table
local menu = {} 
local selection; 
local bannerMenu;
local pointer; 
operSys = love.system.getOS() 

-- -- play function. If called by local options, require game.lua and then load the game.load function in game.lua.

local function play() 
    mode = require 'game'
    mode.load() 
end

local function instructions() 
    mode = require 'instructions'
    mode.load() 
end

    mode = require 'betatesters'
    mode.load()
end

local function changelog() 
    mode = require 'changelog'

    {['text'] = 'Changelog', ['action'] = changelog },
    {['text'] = 'Sound Options', ['action'] = sound},
    {['text'] = 'Exit Game', ['action'] = love.event.quit}

}
-- load function for menu. loads background image, banner, pointer.
function menu.load() 
    background = love.graphics.newImage(MENU_BG)
    bannerMenu = love.graphics.newImage(BANNER)

    pointer = love.graphics.newImage(POINTER)
    mode = menu 
    mac = love.graphics.newImage(MAC)
    windows = love.graphics.newImage(WINDOWS)
    linux = love.graphics.newImage(LINUX)
end 
--  returns mode variable. 
function menu.update() 
    return mode
end 
-- draw function for menu. draws background, banner, prints my personal accrediation, draws pointer.
function menu.draw()
    love.graphics.draw(background)
    love.graphics.draw(bannerMenu, 200, 10)

错误

电晕模拟器运行时错误 尝试索引全局“love”（零值）

文件：main.lua 电话号码：87 堆栈回溯：

main.lua:87：在主块中，这里没有神奇的答案。你需要把代码移植过来

Lua是一个函数，在这些情况下，诸如

love

之类的东西是由宿主程序提供的。您需要将

love2d

环境提供的内容替换为

corona

环境提供的内容

在您的例子中，这几乎是显示的全部代码
