控制台输出两次，车道与玩家重叠
The output on console twice and the lanes overlap the player
我应该得到的输出是当我向右点击时小鸡可以向右跳，反之亦然。但是我在这里无法解决的两个问题是当我点击它时它会像我点击两次一样在控制台中输出。第二个问题是通道排列成阵列并且不断重叠所有东西，甚至是作为玩家的小鸡。
为此，我添加了 2 个 lua 文件和 3 个 png。
这是我的main.lua
display.setStatusBar( display.HiddenStatusBar )
local composer = require( "composer" )
print("entering gotoScene")
composer.gotoScene( "game2" )
print("out from gotoScene")

方法scene:show被调用了两次。一次 event.phase 参数等于 will，第二次 event.phase 参数等于 did。它也适用于 scene.hide 方法。下面的代码检查。
在底部我放了来自Corona documentation的场景模板。可以作为新场景的起点
我用 Runtime:addEventListener("enterFrame", pathScroll) 注释掉了一行。你有两个，但一个就足够了。
