简介
示例
co=coroutine.create(
function()
print("hi");
end
)
print(coroutine.status(co));
coroutine.resume(co);
print(coroutine.status(co));
--[[print:
suspended
hi
dead
]]
co=coroutine.create(
function()
for i=1,2 do
print("hi");
coroutine.yield();
end
end
)
coroutine.resume(co);
print(coroutine.status(co));
coroutine.resume(co);
print(coroutine.status(co));
coroutine.resume(co);
print(coroutine.status(co));
coroutine.resume(co);
print(coroutine.status(co));
--[[print:
hi
suspended
hi
suspended
dead
dead
]]
参数及返回值
create：返回coroutine，参数是函数resume：返回bool值yield：挂起status：返回状态wrap：返回一个函数，调用这个函数时就开始执行，相当于create+resumerunning：返回运行的coroutine
-- bool + 函数返回参数
co=coroutine.create(
function()
return 4,5;
end
)
print(coroutine.resume(co,1,2,3));
--[[print:
true 4 5
]]
-- bool + 传入参数多少
co=coroutine.create(
function(a,b)
print(a,b);
coroutine.yield();
end
)
print(coroutine.resume(co,1,2,3));
--[[print:
1 2
true
]]
-- bool + yield所有参数
co=coroutine.create(
function(a,b)
print(a,b);
coroutine.yield(a+b,a-b,a*b,a/b);
end
)
print(coroutine.resume(co,1,2,3));
--[[print:
1 2
true 3 -1 2 0.5 --所有传递给yield的参数都将返回
]]
-- wrap
co=coroutine.wrap(
function(a)
return 2*a;
end
)
c=co(1);
print(c);
--[[print:
2
]]
