我制作了这个小游戏，一切都运行良好，但我觉得是时候添加一个开始菜单，以使游戏更具代表性。我尝试使用Composer进行场景管理，到目前为止我还没有运气。我没有通过电晕终端收到任何错误，但我也没有在模拟器上看到任何内容，我只是得到一个黑屏。
这是代码
local composer = require( "composer" )
local scene = composer.newScene()
-- -----------------------------------------------------------------------------------------------------------------
-- All code outside of the listener functions will only be executed ONCE unless "composer.removeScene()" is called.
-- -----------------------------------------------------------------------------------------------------------------
-- local forward references should go here

-- Example: add display objects to "sceneGroup", add touch listeners, etc.

答案 0 :(得分：0)
尝试在场景中打印一些东西：这个lua文件的create（）.. 例如：打印（“测试”）..并检查终端以查看是否打印..
