android - 电晕SDK : remove objects after delay

Question

我在我的游戏中创建云，我想在 20 秒后将其移除。问题是当我添加代码来移除它们时，云甚至没有出现，看起来它们在创建时就被移除了。

以下是我已经尝试过的两种方法(均无效):

local function removeBody(body)

    body:removeSelf()
end

local function newCloud()
    local n = cloudNumber
    while n==cloudNumber do
    n = math.random(1,5)
end
    cloudNumber=n
    local cloud = display.newImage(imageNames[cloudNumber], screenW+30, screenH*0.2)
    timer.performWithDelay(6000, newCloud)
    cloud.myName="cloud"
    physics.addBody (cloud, {isSensor=true})
    cloud:setLinearVelocity(-25,0)
    cloud.gravityScale=0
    timer.performWithDelay(20000,removeBody(cloud))
end

和

local function newCloud()
    local n = cloudNumber
    while n==cloudNumber do
    n = math.random(1,5)
end
    cloudNumber=n
    local cloud = display.newImage(imageNames[cloudNumber], screenW+30, screenH*0.2)
    timer.performWithDelay(6000, newCloud)
    cloud.myName="cloud"
    physics.addBody (cloud, {isSensor=true})
    cloud:setLinearVelocity(-25,0)
    cloud.gravityScale=0
    --timer.performWithDelay(20000, cloud:removeSelf())
end

我该怎么办？ 谢谢!

Answer 1

尝试以下代码:

timer.performWithDelay(20000,function() cloud:removeSelf() end)

代替:

timer.performWithDelay(20000,removeBody(cloud))

继续编码................ 😃
