Question

我在电晕模拟器中遇到以下错误。我所知道的文件中没有任何变化。（我已经包含了main.lua代码和menuMain.lua代码。）如果您对可能导致的内容有任何想法，那将会被批评！ =）谢谢。

电晕模拟器运行时错误档案：？尝试调用方法'dispatchEvent'（零值）堆栈追溯： [c]在函数'dispatchEvent'中？在功能gotoScene ... dwegrecki / main.lua:16 in main chunck

- main.lua

-- Hide Status Bar
display.setStatusBar(display.HiddenStatusBar)

-- require controller module
local storyboard = require "storyboard"

-- load first screen
storyboard.gotoScene( "menuMain" )

- menuMain.lua

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