Lua编程示例（七）：协同程序基础逻辑（lua编程零基础教学）这样也行？

co=coroutine.create(function()
for i=1,2 do
print(“co”,i)
coroutine.yield()
end
end)
coroutine.resume(co)
print(coroutine.status(co))

coroutine.resume(co)
print(coroutine.status(co))

coroutine.resume(co) –没有输出
print(coroutine.status(co))
print()

co=coroutine.create(function(a,b,c)
print(“co”,a,b,c)
end)
coroutine.resume(co,1,2,3)

co=coroutine.create(function(a,b)
print(“I’m before yield”) –第一次运行执行
coroutine.yield(a+b,a-b,”needless args”) –在这停住,返回yield的参数
print(“Mgs”)
end)
print(coroutine.resume(co,20,10)) –参数传给yield,处理后再返回
print(“I print first”)
coroutine.resume(co)

co=coroutine.create(function()
return “I’ll return”
end)
print(coroutine.resume(co)) –主函数的返回值回传给resume
print()
