如何播放一个按钮点击的声音，只有一次在电晕sdk？

当用户点击按钮时，我只想播放一次声音，我怎么能做到

以下是我到目前为止所做的工作，但如何添加声音：

local widget = require( "widget" )
--button performed only once
local minusButtonPressed = false

local function handleButtonEvent( event )

    if ( ( "ended" == event.phase ) and (minusButtonPressed == false) and (afterCorrect == false)) then
        minusScore() 
        print( "Button was pressed and released" )
        --disable the button
        minusButtonPressed = true
    end
 end


local button1 = widget.newButton
{
    width = 350,
    height = 360,
    left= 30,
    top= 220,
    defaultFile = "speakers.png",
    overFile = "wrong.png",
    --label = "button",
    onEvent = handleButtonEvent
}

我不知道这是否是您的程序所需要的，但请尝试包含音频库 和使用

local laserSound = audio.loadSound( "laserBlast.wav" ) //init the sound 
local laserChannel = audio.play( laserSound )  //play the sound once complete
