我对corona SDK composer API有一点问题。我有3个.lua文件 - main.lua，character.lua和job.lua。问题是，当我运行游戏时，它会自动转换为character.lua，一切都很好。然后我转移到job.lua并且它也可以工作，但是当我试图回到角色时。没有任何反应（背景不会改变）。那就是＆＃39;它的样子：
main.lua：
local composer = require("composer")
composer.gotoScene("character")
character.lua：
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
-- -------------------------------------------------------------------------------
-- "scene:create()"
function scene:create( event )
local sceneGroup = self.view
-- Initialize the scene here.
-- Example: add display objects to "sceneGroup", add touch listeners, etc.
local widget = require("widget")
local bottomTabButtons ={
{ width=32, height=32, defaultFile="character.png", overFile="character_active.png", selected="true"},
{ width=32, height=32, defaultFile="job.png", overFile="job_active.png", onPress=function() composer.gotoScene( "job" )end},
}
local bottomBar = widget.newTabBar{
top = display.contentHeight-40,
buttons = bottomTabButtons
}
end
-- "scene:show()"
function scene:show( event )
local sceneGroup = self.view
local phase = event.phase
if ( phase == "will" ) then
-- Called when the scene is still off screen (but is about to come on screen).
elseif ( phase == "did" ) then
-- Called when the scene is now on screen.
-- Insert code here to make the scene come alive.
-- Example: start timers, begin animation, play audio, etc.
end
end
-- "scene:hide()"
function scene:hide( event )
local sceneGroup = self.view
local phase = event.phase
if ( phase == "will" ) then
-- Called when the scene is on screen (but is about to go off screen).
-- Insert code here to "pause" the scene.
-- Example: stop timers, stop animation, stop audio, etc.
elseif ( phase == "did" ) then
-- Called immediately after scene goes off screen.
end
end
-- "scene:destroy()"
function scene:destroy( event )
local sceneGroup = self.view
-- Called prior to the removal of scene's view ("sceneGroup").
-- Insert code here to clean up the scene.
-- Example: remove display objects, save state, etc.
end
-- -------------------------------------------------------------------------------
-- Listener setup
scene:addEventListener( "create", scene )
scene:addEventListener( "show", scene )
scene:addEventListener( "hide", scene )
scene:addEventListener( "destroy", scene )

提前致谢！
答案 0 :(得分：3)
问题是您没有将显示对象插入到场景组中。这就是为什么它不被删除。将所有对象插入到场景组中。
例如，
local background = display.newImage("background.png")
background.x=display.contentCenterX
background.y=display.contentCenterY
background.height=display.contentHeight
background.width=display.contentWidth
sceneGroup:insert(background)
---这是改变。以同样的方式将所有对象插入此组。
