我创建了一个带有 2 个按钮的菜单，并且我正在使用情节提要 API 在场景中移动，但它仅适用于第一个按钮，对于另一个按钮它会显示黑屏，我确信 SCENE 2 中没有任何问题，因为我尝试将两个场景（SCENE 1 和 SCENE 2）设置为相同的代码，它与 SCENE 1 一起使用，但仍然为 SCENE 2 提供黑色图像，这是我的菜单代码，希望你能修复错误：

local storyboard = require ("storyboard")
local scene = storyboard.newScene()


   function scene:createScene(event)

local screenGroup = self.view

background = display.newImage("start.png")
background:setReferencePoint(display.BottomLeftReferencePoint)
background.x = 0
background.y = 320
background.speed = 1
screenGroup:insert(background)

city2 = display.newImage("city2.png")
city2:setReferencePoint(display.BottomLeftReferencePoint)
city2.x = 0
city2.y = 320
screenGroup:insert(city2)



play = display.newImage("play.png")
play.x = 242

screenGroup:insert(play)

if event.phase == "began" then
    storyboard.gotoScene("SCENE1", "fade", 400)
end
end

    storyboard.gotoScene("SCENE2", "fade", 400)
end
end

function scene:enterScene(event)

我认为问题在于scene:enterScene您尝试一遍又一遍地加载您的城市对象，同时您的代码中有太多运行时侦听器，以至于它重复调用同一个对象。你在创造一个横向卷轴游戏吗？如果是这样，您可以尝试查看有关如何从头开始创建横向滚动游戏的链接http://mobile.tutsplus.com/tutorials/corona/corona-sdk-create-a-side-scroller-from-scratch/ 希望这个帮助
