Question

我不确定我是否误解了coroutine的使用，但这是我的代码：

talk = coroutine.create(function ()
print("I am speaking within 60 seconds")
end)

time = coroutine.create(function ()
if coroutine.status(talk) == running then
for i = 60, 0, -1 do
print(i)
end
sleep(1)
else
coroutine.resume(talk)
end

end)
coroutine.resume(time)

所有打印的是我在60秒内发言，我期待它在倒计时内说出来。我该如何解决这个问题？

Answer 1

talk = coroutine.create(function ()
print("I am speaking within 60 seconds")
coroutine.resume(time)
end)

time = coroutine.create(function ()
for i = 60, 0, -1 do
print(i)
coroutine.resume(talk)
end

end)

coroutine.resume(time)

Answer 2

talk = coroutine.create(function ()
    print("I am speaking within 60 seconds")
    coroutine.yield()
end)

time = coroutine.create(function ()
    for i = 60, 0, -1 do
        coroutine.resume(talk)
        print(i)
    end
end)

coroutine.resume(time)

Answer 3

你正在呼叫睡眠，但我没有看到某个地方声明了这个功能。这是一个已实现sleep（）的修改版本：

local function sleep(time)
    local sleep_until = os.time() + time
    repeat until os.time() >= sleep_until
end

local time, talk

talk = coroutine.create(function ()
    print("I am speaking in 60 seconds")
    coroutine.resume(time)
end)

time = coroutine.create(function ()
    while true do
        for i = 60, 0, -1 do
            print(i)
            sleep(1)
        end
        coroutine.resume(talk)
    end
end)

coroutine.resume(time)

错误使用协同程序
