Question

是否有办法提及目前在卢阿执行匿名职能? 就像我们在 Java里可以做的那样,用arguments.questee。

例如:

local function newLiftAnimator(obj)
  local count = 0
  return function(event)
    -- animate obj s properties here on each "enterFrame" event
    obj.y = obj.y - 1
    count = count + 1
    -- when done, remove event listener
    if count >= 100 then
      Runtime:removeEventListener("enterFrame", **<this_function>**)
    end
  end
end

Runtime:addEventListener("enterFrame", newLiftAnimator(ball))

Answer 1

提出

local f
f=function (event) ... Runtime:removeEventListener("enterFrame", f) ... end
return f

Answer 2

永远不会忘记。在阅读

local function newLiftAnimator(obj)
  ...
  local function animator()
    ...
    Runtime:removeEventListener("enterFrame", animator)
  end
  return animator
end

Answer 3

另一种可能性是:

debug.getinfo(1, f ).func
