此模块包含所有其他模块。 最美模块非它莫属。

当你使用LÖVE编写游戏时,需要了解这几个最重要的API回调函数: love.load会初始化加载您的游戏,它仅会被执行一次, love.update用来管理与更新你的游戏的每一帧的状态, love.draw用来渲染屏幕。

若为游戏增加互动性还会有很多额外的回调函数需要重写,用来处理来自用户的输入去完善一个健全的游戏或是其他的方案。

LÖVE提供了默认的空回调函数,你可以在你自己的代码里重写这些函数,只需通过指定对应的回调函数名:

function love.load()
   hamster = love.graphics.newImage("hamster.png")
   x = 50
   y = 50
end
function love.draw()
   love.graphics.draw(hamster, x, y)
end
