Corona SDK 作曲家 - 改变场景不起作用

Question

我在使用 Corona SDK Composer 时遇到了一点问题 API。我有 3 个 .lua 文件 - main.lua、character.lua 和 job.lua。问题是，当我运行游戏时，它会自动过渡到 character.lua 并且一切正常。然后我过渡到 job.lua 并且它也能正常工作，但是当我试图回到 character.lua 时 - 没有任何反应（背景没有改变）。这就是它的样子：

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 )

return scene

job.lua:

Answer 1

问题是您没有将显示对象插入到场景组中。这就是为什么它没有被删除的原因。将所有对象插入场景组。

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)

--- 这就是变化。以同样的方式将所有对象插入到该组中。
