button - 声音和音乐Corona SDK的2个开关按钮？

Question

我需要有关小部件切换按钮的帮助。我创建了2个切换按钮，用于声音切换和音乐切换，但是问题是每次我关闭并打开音乐开关时，音乐(mp3声音)都没有响应，这意味着每次我打开音乐时其速度都会快进/关闭。下一个问题是每当我关闭声音开关时，它也会关闭音乐(mp3声音)。
这是我的代码:

--utils.lua

local sounds = {}
sounds["select"] = audio.loadSound("sounds/select.mp3")
sounds["score"] = audio.loadSound("sounds/score.mp3")
sounds["incorrect"] = audio.loadSound("sounds/gameover.mp3")
sounds["clap"] = audio.loadSound("sounds/clapping.mp3")
sounds["music"] = audio.loadSound("sounds/gameMusic.mp3")

M.playSound = function(name) 
    if sounds[name] ~= nil then 
        audio.play(sounds[name])
    end
end

--Settings.lua

soundSwitchPressed = function(event)
local switch = event.target
utils.playSound("select")


if switch.id == "sound" then 
    if switch.isOn == true then 
        audio.setVolume(0)
    else
        audio.setVolume(1)
    end
end
end

musicSwitchPressed = function(event)
    local switch = event.target
    utils.playSound("music")

    if switch.id == "music" then 
        if switch.isOn == true then 
            audio.setVolume(0)
        else
            audio.setVolume(1)
        end

    end
end



local sound_switch = widget.newSwitch
    {  
        left = _W-70,
        top = navBar.y + navBar.height/2 + 44,
        style = "onOff",
        id = "sound",
        x = 800,
        y = 960,   
        onPress = soundSwitchPressed
    }
    sound_switch.xScale, sound_switch.yScale = 3, 3
    uiGroup:insert(sound_switch)

    local music_switch = widget.newSwitch
    {  
        left = _W-70,
        top = navBar.y + navBar.height/2 + 44,
        style = "onOff",
        id = "music",
        x = 800,
        y = 1200,   
        onPress = musicSwitchPressed
    }

    if audio.getVolume() == 0 then 
        sound_switch:setState({isOn=false, isAnimated=false})
        music_switch:setState({isOn=false, isAnimated=false})
    else
        sound_switch:setState({isOn=true, isAnimated=false})
        music_switch:setState({isOn=true, isAnimated=false})
    end
end

我不确定您的方式是否正确。我是初学者，但我想帮助您:)

从Corona文档中了解 audio.setVolume()

Sets the volume either for a specific channel, or sets the master volume.

因此， audio.setVolume()影响所有声音和音乐。

也许尝试使用变量来确定是否播放声音和音乐。

utils.lua

audio.reserveChannels( 6 )
...
sounds["select"] = audio.loadSound("sounds/select.mp3")
sounds["score"] = audio.loadSound("sounds/score.mp3")
sounds["incorrect"] = audio.loadSound("sounds/gameover.mp3")
sounds["clap"] = audio.loadSound("sounds/clapping.mp3")
sounds["music"] = audio.loadSound("sounds/gameMusic.mp3")

local channels = {}
sounds["select"] = 1
sounds["score"] = 2
sounds["incorrect"] = 3
sounds["clap"] = 4
sounds["music"] = 5

music = audio.loadStream( "backgroundMusic.mp3" ) 

M.soundOn = true
M.musicOn = true

M.playMusic = function() 
    if music ~= nil then 
        audio.play( music, { channel = 6 })
    end
end

M.playSound = function(name) 
        if sounds[name] ~= nil then 
            audio.play(sounds[name], { channel = channels[name]})
        end
    end

Settings.lua

...
soundSwitchPressed = function(event)
local switch = event.target

if utils.soundOn then
    utils.playSound("select")
end

if switch.id == "sound" then 
    if switch.isOn == true then 
        utils.soundOn = true
    else
        utils.soundOn = false
        audio.stop(1)
        audio.stop(2)
        audio.stop(3)
        audio.stop(4)  
        audio.stop(5) 
    end
end
end
...

musicSwitchPressed = function(event)
    local switch = event.target

    if utils.musicOn then
        utils.playSound("music")
    end

    if switch.id == "music" then 
        if switch.isOn == true then 
            utils.musicOn = true
            utils.playMusic()
        else
            utils.musicOn = false
            audio.stop(6)
        end

    end
end

每当您播放声音放置代码

if utils.soundOn then
    utils.playSound("your_sound_effect_name")
end

要么

if utils.musicOn then
    utils.playMusic()
end
