Question

我有这个onCollision功能，但每次游戏开始时碰撞加倍

local function onCollision(event)
    if event.phase == "began" and gameIsActive == true then
        local obj1 = event.object1; 
        local obj2 = event.object2; 

    if obj1.name == "jetplayer" and obj2.name == "BCloud1" then   
        MinLife()

        elseif obj1.name == "jetplayer" and obj2.name == "BCloud2" then
        pontsMin10()

        elseif obj1.name == "jetplayer" and obj2.name == "BCloud3" then
        pontsMin20()

        elseif obj1.name == "jetplayer" and obj2.name == "GCloud1" then
        pontsplus50()

        elseif obj1.name == "jetplayer" and obj2.name == "bla" then
        score = score - 20

        end
    end
end
Runtime:addEventListener( "collision", onCollision )

function scene:exitScene( event )
Runtime:removeEventListener( "collision", onCollision )

有没有理由发生这种情况？

Answer 1

确保local function onCollision(event)超出其他功能。

也许问题出在您的Runtime:removeEventListener( "collision", onCollision )中，它无法找到onCollision，因为它位于其他功能内部。

Answer 2

    if obj1.name == "jetplayer" and obj2.name == "BCloud1" then MinLife()
elseif obj1.name == "jetplayer" and obj2.name == "BCloud2" then pontsMin10()
elseif obj1.name == "jetplayer" and obj2.name == "BCloud3" then pontsMin20()
elseif obj1.name == "jetplayer" and obj2.name == "GCloud1" then pontsplus50()
elseif obj1.name == "jetplayer" and obj2.name == "bla"     then score = score - 20
end

仅供参考，这是obj1.name == "jetplayer"的大量冗余测试。我会重写那段代码进行一次测试：

    if obj1.name == "jetplayer" then
        if     obj2.name == "BCloud1" then MinLife()
        elseif obj2.name == "BCloud2" then pontsMin10()
        elseif obj2.name == "BCloud3" then pontsMin20()
        elseif obj2.name == "GCloud1" then pontsplus50()
        elseif obj2.name == "bla"     then score = score - 20
        end
    end

我第一次开始游戏并且我点击了“MinLife（）”它会让一生失去，但当你重新开始游戏'gameover.lua-＆gt; start.lua-＆gt; game.lua'当你点击“ MinLife（）“它需要2次生命，第3次重启3次生命等等

您没有显示MinLife，因此我们无法知道该代码中是否存在错误。我会检查你是不是多次添加你的碰撞处理程序（例如确保你的exitScene处理程序被攻击等）。

碰撞加倍加班你重新开始比赛
