J'ai créé un jeu en utilisant le cadre love2d et maintenant je veux le transférer à la corona sdk. Malheureusement, je reçois une erreur car corona ne supporte pas les fonctions d'amour. Comment corriger cela? Merci!Comment faire pour modifier le code love2d pour corona sdk (les deux sont dans la langue lua)
main.lua (essentiellement les fonctions de love.something lancent erreur comme indiqué au bas de cette page)
-- load function to call menu.load() from menu.lua
function love.load()
mode = require "menu"
mode.load()
end
-- draw function for images
function love.draw()
mode.draw()
end
-- keypressed function to control user inputs
function love.keypressed(key, isrepeat)
mode.keypressed(key)
end
-- update function (delta time) to update variables/perform mathematical calculations.
function love.update(dt)
mode.update(dt)
end
menu.lua
-- 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
-- instructions function. If called by local options, require instructions.lua and then load the instructions page.
local function instructions()
mode = require 'instructions'
mode.load()
end
local function betatest()
mode = require 'betatesters'
mode.load()
end
local function changelog()
mode = require 'changelog'
mode.load()
end
local function sound()
mode = require 'sound'
mode.load()
end
-- displays options that user can select from
local options = {
{['text'] = 'Play', ['action'] = play},

{['text'] = 'Exit Game', ['action'] = love.event.quit}
}
-- load function for menu. loads background image, banner, pointer.
function menu.load()

end

end
if operSys == "Windows" then
love.graphics.draw(windows,530,510)
end
if operSys == "Linux" then
love.graphics.draw(linux, 530,510)
end
for i=1,#options do
if i == selection then
love.graphics.draw(pointer, 300, 160 + i * 20)
end
love.graphics.printf(options[i].text,-10,160 + i * 20, love.graphics.getWidth(), 'center')
end
end
-- keypressed function for menu. Controls user selection
function menu.keypressed(key)
if key == "up" then
selection = (selection - 2) % (#options) + 1
elseif key == "down" then

end
end
