如何使按钮在corona sdk中只按下一次而不重复按下？

我正在制作一个问题应用程序，当你选择正确的答案按钮时，分数会增加+1，选择错误答案时，分数会增加-1， 我如何使按钮能够按一次，但之后不能再按？因为如果你一直按按钮，分数会不断增加

这是按钮1：

local widget = require( "widget" )


local function handleButtonEvent( event )

    if ( "ended" == event.phase ) then 
    minusScore()

        print( "Button was pressed and released" )
    end
end 

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

这是分数函数。也许有一种方法，分数加1，然后停止：

-------------------得分------------------------

local score = 0
local scoreTxt = display.newText( "0", 0, 0, "Helvetica", 40 ) 
scoreTxt:setReferencePoint(display.TopLeftReferencePoint)
scoreTxt.x = display.screenOriginX + 700
scoreTxt.y = display.screenOriginY + 37
scoreTxt:setTextColor(2,2,2)
---------------------score added 10-----------------------------
function updateScore()
    score = score + 1
    _G.score = score
    scoreTxt.text = string.format(" %d", score)
end
local scoretimer = timer.performWithDelay(1, updateScore,1)
---------------------score minus 1-----------------------------
 function minusScore()
    score = score - 1
    _G.score = score
   scoreTxt.text = string.format(" %d", score)
end
local scoretimer = timer.performWithDelay(1, minusScore,1)

---

你可以这样做：

local minusButtonPressed = false

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

您可能还想将按钮的alpha值更改为.5，以显示在同一功能中已禁用。它起作用了！非常感谢你！从永远开始，我一直在努力寻找答案！在移动到下一个场景后，有没有办法阻止按钮被按下？是的，看看这个。在您的情况下，minusButtonPressed变量就是您要保存其状态的变量。有很多方法可以做到这一点，它们有不同的优点和缺点。
