在Corona SDK中停止事件传播

我正在使用Corona SDK和Director 1.4来创建应用。我的目标是在单击按钮(btn_play)时打开弹出窗口。

然而,我遇到了一个问题。单击btn_play时,它会触发openPopup(e)以及changeScene(e)(因为后台设置为执行该功能)。如何在单击changeScene(e)按钮时停止执行btn_play功能?

这是我的游戏屏幕代码:

module(..., package.seeall)

local localGroup

function new()
    localGroup = display.newGroup();

    -- Background Image
    local background = display.newImageRect("background.jpg", display.contentWidth, display.contentHeight )
    background:setReferencePoint( display.TopLeftReferencePoint )
    background.x, background.y = 0, 0
    background.scene = "scene_menu";

    -- Play button
    local btn_play = display.newImageRect("grass.png", 320, 82 )
    btn_play:setReferencePoint( display.CenterReferencePoint )
    btn_play.x = display.contentWidth * 0.5
    btn_play.y = 600
    btn_play.scene = "inventory"

    localGroup:insert(background);
    localGroup:insert(btn_play);

    function changeScene(e)
        if(e.phase == "ended") then
            director:changeScene(e.target.scene);
        end
    end

    function openPopup(e)
        if(e.phase == "ended") then
            director:openPopUp(e.target.scene);
        end
    end

    background:addEventListener("touch", changeScene);
    btn_play:addEventListener("touch", openPopup);

    return localGroup;
end

只需将return放在功能的末尾即可。它将阻止touch到底层对象。

function openPopup(e)
    if(e.phase == "ended") then
        director:openPopUp(e.target.scene);
        return true; -- put this in your function.
    end
end

保持编码..............:)
