Question

嗨，由于某种原因，我无法得到本地直升机= display.newImage（“helicopter.png”）显示在云端（移动背景），是否有一个很好的方法解决这个问题？

<code>
function initcloud()
    local cloud1 = {}
    cloud1.imgpath = "cloud1.png"; --Set Image Path for cloud
    cloud1.movementSpeed = 10000; --Determines the movement speed of cloud
    table.insert(cloudTable, cloud1); --Insert cloud into cloudTable

    local cloud2 = {}
    cloud2.imgpath = "cloud2.png";
    cloud2.movementSpeed = 12000;
    table.insert(cloudTable, cloud2);               

    local cloud3 = {}
    cloud3.imgpath = "cloud3.png";
    cloud3.movementSpeed = 14000;
    table.insert(cloudTable, cloud3);
end --END initcloud()   

function getRandomcloud()
local temp = cloudTable[math.random(1, #cloudTable)] -- Get a random cloud from cloudTable
local randomcloud = display.newImage(temp.imgpath); --physics.addBody(randomcloud, {isSensor = true});
randomcloud.myName = "cloud";
randomcloud.movementSpeed = temp.movementSpeed; -- set the cloud cloudting point
randomcloud.x = math.random(10, _W);
randomcloud.y = -35;
randomcloud.rotation = math.random(0, 20); -- move the cloud
cloudMove = transition.to(randomcloud, {
time = randomcloud.movementSpeed, 
y = 500,
onComplete = function(self)
self.parent:remove(self);
self = nil;
end 
});
end

function cloudtGame()
    cloudTimer1 = timer.performWithDelay(1400,getRandomcloud, 0)
    cloudTimer2 = timer.performWithDelay(2000,getRandomcloud, 0)
    cloudTimer3 = timer.performWithDelay(2400,getRandomcloud, 0)        
end--END cloudtGame()

initcloud()
cloudtGame()

local helicopter = display.newImage("helicopter.png")
</code>

谢谢

当我使用我的解决方案运行您的代码时，它工作正常。我添加的只是：

randomcloud:toBack()

因为randomcloud是一个显示对象，我可以将它发送到页面的后面。

最简单的解决方案是使用两个DisplayGroup（一个用于云，一个用于直升机）以所需顺序安装在一个“根”组内。这样你只有一个没有组的对象 - “根”。
