Lua中如何实现Yield break？ about xlua

[chexiongsheng]

lua那直接return就可以相当于Yield break。
不用stopCoroutine，你不resume协程，然后引用也不指向它，自然它会被gc掉。

如果我想中断一个运行中的Coroutine(不通过内部return的方式)，你的建议是什么呢？

[chexiongsheng]

在外部没有什么中断好说，lua是单线程的，当你在外部的时候，就代表这个协程不在运行，你不resume直接抛弃掉即可。

[chexiongsheng]

你是被Unity用genarator模拟的协程给误导了。Unity的模拟需要把一个genarator注册到协程调度里头，你在外部也要调用个Stop来反注册。

[dongxue]

在06_Coroutine范例中我通过在coruntine_test.lua中使用CS.GameObject.Destroy(gameobject)来实现了

[chexiongsheng]

哦，我理解错了，你是要中断在和Unity协程配合时，怎么清理Unity协程的问题。。不好意思！

[dongxue]

另外我想请教下，为了hotfix，我理论上是不是可以给所有自己的C#类打上HOTFIX_ENABLE，这样做有什么坏处么？

我在这里有分析overhead：https://www.zhihu.com/question/54344452，可以去看看

但是他报这个错啊，我啥都没管

`
local yield_return = (require 'cs_coroutine').yield_return
self.co = coroutine.create(function()
while true and not self.stop_coroutine do
for i,v in ipairs(self.all_item) do
if self.all_item[i].IsNull() then

						end
						self.all_item[i].anchoredPosition = Vector2(0, self.all_item[i].anchoredPosition.y + 1)
						if self.all_item[i].anchoredPosition.y >= 90 then
							self.all_item[i].anchoredPosition = Vector2(0,-(#self.all_item - 1) * (90 + 6))
						end
					end
					if not self.stop_coroutine then
						return
					end
					yield_return(CS.UnityEngine.WaitForSeconds(0.0001))
				end
			end)
			coroutine.resume(self.co)
