如何在没有用户输入（如幻灯片放映）的情况下从一个 lua 场景移动到另一个场景？

Question

如何在没有用户输入或按钮的情况下将一个 lua 文件替换为另一个 lua 文件（如幻灯片）？声音结束？定时器？

例如，场景 1 中的编码：

-- visuals

   positionOne = display.newImage( note1, 170, pitch1 ) 
-- first of the two notes in the bar: 170 = x coordinate, pitch = y         

   coordinate
   positionTwo = display.newImage( note2, 320, pitch2 ) 
-- second of the two notes in the bar

-- accomp 1

    local accomp = audio.loadStream("sounds/chord1.mp3")
        audio.play(accomp, {channel = 1})
    audio.stopWithDelay(60000/72)
    -- 72 = beats per minute
-- accomp 2

    local function listener(event)  
    local accomp = audio.loadStream("sounds/chord2.mp3")
        audio.play(accomp, {channel = 2})
    audio.stopWithDelay(60000/72])
    end
    timer.performWithDelay(60000/72, listener)
    end

音乐结束后，此操作将继续：

-- visuals

   positionOne = display.newImage( note1, 170, pitch3 ) 
-- first of the two notes in the bar: 170 = x coordinate, pitch = y         

   coordinate
   positionTwo = display.newImage( note2, 320, pitch4 ) 
-- second of the two notes in the bar

-- accomp 1

    local accomp = audio.loadStream("sounds/chord3.mp3")
        audio.play(accomp, {channel = 1})
    audio.stopWithDelay(60000/72)
    -- 72 = beats per minute
-- accomp 2

    local function listener(event)  
    local accomp = audio.loadStream("sounds/chord4.mp3")
        audio.play(accomp, {channel = 2})
    audio.stopWithDelay(60000/72])
    end
    timer.performWithDelay(60000/72, listener)
    end

作为一个新手编码员，我无法理解Corona现成的多场景编码，无论如何都依赖于用户输入按钮。我注意到在启动这样一个项目时，main 直接移动到 scene1，没有 ui。其他场景也能这样吗？我哪里错了？

Answer 1

您可以使用 timer.performWithDelay() 安排场景切换，因为您可以计算第二个音频播放何时停止。类似于：

local function switchScene()
   composer.gotoScene( "scene2", { effect = "slideLeft", time = 500} )
end

-- start the audio stuff here as before...

-- Register scene switch to happen once the audio is done
local timeBeforeSwitch = 2*(60000/72)
timer.performWithDelay(timeBeforeSwitch, switchScene)

作为替代方案，它应该注册一个 onComplete 回调到最后一个音频播放调用，如下所示：

audio.play(accomp, {channel = 2, onComplete=switchScene})

但我还没有测试过它是否按预期与 audio.stopWithDelay()
