在情节提要中看不到文字

Question

我对 Corona SDK 还很陌生，正在尝试制作游戏菜单，但是当我运行代码时，它只是不显示文本。我确信该程序可以访问此文件。知道为什么吗？

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

display.setStatusBar (display.HiddenStatusBar)

local function ButtonTap (event)
  storyboard.gotoScene(event.target.goto, {effect="slideDown"})
  return true
end

function scene:CreateScene (event)
  local group = self.view

  -->Play Button
  local PlayBtn = display.newText ("Play",0,0)
  PlayBtn.x = display.contentHeight/2
  PlayBtn.y = display.contentWidth/2
  PlayBtn.goto = "Play"
  PlayBtn:addEventListener("tap", ButtonTap)
  group:insert(PlayBtn)

  -->Exit Button
  local ExitBtn = display.newText ("Play",0,0)
  ExitBtn.x = display.contentHeight/2
  ExitBtn.y = display.contentWidth/2 + 60
  ExitBtn.goto = "Play"
  ExitBtn:addEventListener("tap", ButtonTap)
  group:insert(ExitBtn)
end


-- Called immediately after scene has moved onscreen:
function scene:enterScene( event )
  local group = self.view

end

-- Called when scene is about to move offscreen:
function scene:exitScene( event )
  local group = self.view

end


-- Called prior to the removal of scene's "view" (display view)
function scene:destroyScene( event )
  local group = self.view

end

scene:addEventListener( "createScene", scene )
scene:addEventListener( "enterScene", scene )
scene:addEventListener( "exitScene", scene )
scene:addEventListener( "destroyScene", scene )

return scene

提前致谢:)

Answer 1

function scene:CreateScene( event ) 应该是 function scene:createScene( event ) 如果您遵循标准命名约定。 Lua 区分大小写。在：

scene:addEventListener( "createScene", scene )

您使用的是小写的“c”，但在函数中，您使用的是大写的“C”。这些必须匹配，并且 Corona 标准将与小写版本一起使用。
