我創造了我的遊戲中的雲,我想在20秒後刪除。問題是,當我添加代碼來刪除它們時,雲甚至不會出現,看起來它們在創建時就被刪除了。Corona SDK:延遲後刪除對象

這裏有兩種方法我試過已經(其中沒有工作):

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 

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 

我該怎麼辦? 謝謝!

試試下面的代碼:

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

相反的:

timer.performWithDelay(20000,removeBody(cloud)) 

保持編碼................

完美!謝謝! – dietbacon
