我在我的游戏中创建云,我想在 20 秒后删除。问题是当我添加代码以删除它们时,云甚至都没有出现,似乎它们在创建时就被删除了。
以下是我已经尝试过的两种方法(都没有奏效):
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
我应该怎么办?谢谢!
