audio - 是否可以使用结束的声音文件过渡到新场景或刷新同一场景中的数据？

Question

Lua新手问:
我该如何过渡...
(建立操作方法的简单示例)...

visual = display.newImage( "redCircle.png", 50, 50 ) 

local music = audio.loadStream("sound1.mp3")
    audio.play(music)

audio.stopWithDelay(60000/60)

为此，由第一个声音文件结束计时？

visual = display.newImage( "blueCircle.png", 50, 50 ) 

local music = audio.loadStream("sound2.mp3")
audio.play(music)

audio.stopWithDelay(60000/60)

我应该尝试哪种API？我看过https://docs.coronalabs.com/api/index.html
我想念什么？

Answer 1

您可以做的是为第一个音频文件创建一个函数侦听器，您可以在此处查看更多信息:https://docs.coronalabs.com/api/library/audio/play.html下面是我可以给您的示例代码。请注意，我没有使用audio.stopWithDelay

--DECLARE LOCAL VARIABLES
local visual1
local visual2
local music1 
local music2

--LOAD SOUNDS
music1 = audio.loadStream("sound1.mp3")
music2 = audio.loadStream("sound2.mp3")

local function soundIsFinished(event)

    if (event.completed) then

        --PLAY SECOND AUDIO AND HIDE/REMOVE VISUAL 1
        visual1.isVisible = false
        visual2.isVisible = true
        audio.play(music2, {duration = 1000})       

    end

end

--DISPLAY VISUAL1 and play MUSIC1
visual1 = display.newImage("redCircle.png", 50,50)

--AUDIO WILL PLAY FOR 1 SECOND (60000/60) is 1 second
audio.play(music1, { duration=1000, onComplete=soundIsFinshed } )

-- HIDE VISUAL2 FIRST
visual2 = display.newImage("blueCircle.png", 50,50)
visual2.isVisible = false

希望这可以帮助。
