Lua代码报错：缺少end闭合行102函数，求排查解决

你的错误根源是多个匿名函数未用end闭合，Lua语法要求每个function()必须对应一个end，你目前只给scissorsButton的tap事件函数加了end，但前面三层函数都没闭合：

• 最外层的button:addEventListener("tap", function()
• rockButton:addEventListener("tap",function()
• paperButton:addEventListener("tap",function()

以下是补全end并调整缩进后的完整代码：

button:addEventListener("tap", function()

    buttonText.isVisible=false
    button.isVisible=false
    sun.isVisible=false
    myText.isVisible=false
    myText=display.newText("Rock, Paper, Scissors",w*.5,h*.1,native.systemFont,30)
    myText:setFillColor(unpack(limegreen))

    options={"rock","paper","scissors"}
    computerChoice=options[math.random(3)]

    local rockButton = display.newRoundedRect(w*.5,h*.3,w*.5,h*.2,25)
    rockButton.anchorX=.5
    rockButton.anchorY=.5
    rockButton:setFillColor(unpack(redorange))
    local rockText=display.newText("Rock",w*.5,h*.3,systemFont,50)
    rockText:setFillColor(unpack(blue))

    local paperButton = display.newRoundedRect(w*.5,h*.6,w*.5,h*.2,25)
    paperButton.anchorX=.5
    paperButton.anchorY=.5
    paperButton:setFillColor(unpack(redorange))
    local paperText=display.newText("Paper",w*.5,h*.6,systemFont,50)
    paperText:setFillColor(unpack(blue))

    local scissorsButton = display.newRoundedRect(w*.5,h*.9,w*.5,h*.2,25)
    scissorsButton.anchorX=.5
    scissorsButton.anchorY=.5
    scissorsButton:setFillColor(unpack(redorange))
    local scissorsText=display.newText("Scissors",w*.5,h*.9,systemFont,50)
    scissorsText:setFillColor(unpack(blue))

    rockButton:addEventListener("tap",function()

        paperText.isVisible=false
        scissorsButton.isVisible=false
        scissorsText.isVisible=false
        playerChoice="rock"
        local computerChoiceText=display.newText("Computer's Choice: "..computerChoice,w*.5,h*.3,native.systemfont,25)

        if computerChoice=="paper" then
            local whoWonText=display.newText("Player Choice: "..playerChoice.."You LOST!",w*.5,h*.5,native.systemFont,20)

        elseif computerChoice=="scissors" then
            local whoWontText=display.newText("Player Choice: "..playerChoice.."You WON!",w*.5,h*.5,native.systemFont,20)

        else
            local whoWontText=display.newText("Player Choice: "..playerChoice.."You TIE!",w*.5,h*.5,native.systemFont,20)
        end
    end) -- 闭合rockButton的tap函数

    paperButton:addEventListener("tap",function()
        rockButton.isVisible=false
        rockText.isVisible=false
        paperButton.isVisible=false
        paperText.isVisible=false
        scissorsButton.isVisible=false
        scissorsText.isVisible=false
        playerChoice="paper"
        local computerChoiceText=display.newText("Computer's Choice: "..computerChoice,w*.5,h*.3,native.systemfont,25)

        if computerChoice=="paper" then
            local whoWonText=display.newText("Player Choice: "..playerChoice.."You Tie!",w*.5,h*.5,native.systemFont,20)

            local whoWontText=display.newText("Player Choice: "..playerChoice.."You WON!",w*.5,h*.5,native.systemFont,20)

        else
            local whoWontText=display.newText("Player Choice: "..playerChoice.."You TIE!",w*.5,h*.5,native.systemFont,20)
        end
    end) -- 闭合paperButton的tap函数

    scissorsButton:addEventListener("tap",function()

        rockText.isVisible=false
        paperButton.isVisible=false
        paperText.isVisible=false
        scissorsButton.isVisible=false
        scissorsText.isVisible=false
        playerChoice="scissors"
        local computerChoiceText=display.newText("Computer's Choice: "..computerChoice,w*.5,h*.3,native.systemfont,25)

        if computerChoice=="paper" then
            local whoWonText=display.newText("Player Choice: "..playerChoice.."You WON!",w*.5,h*.5,native.systemFont,20)

        else
            local whoWontText=display.newText("Player Choice: "..playerChoice.."You LOST!",w*.5,h*.5,native.systemFont,20)
        end
    end) -- 闭合scissorsButton的tap函数

end) -- 闭合最外层的button tap函数

额外建议：写嵌套函数时用缩进区分层级，能直观看到哪个function缺了end，避免类似语法错误。
