Lua编程(七)协同程序基础逻辑

 
co=coroutine.create(function()
	print("hi")
end)
print(coroutine.status(co))
coroutine.resume(co)
print(coroutine.status(co))
print()

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()


输出结果:

suspended
hi
dead

co	1
suspended
co	2
suspended
dead

co	1	2	3
I'm before yield
true	30	10	needless args
I print first
Mgs
true	I'll return
