我想在10秒定時器上更新我的進程狀態。如何在計時器上更新我的PID?
-define(INTERVAL, 3000).
start_link() ->
gen_server:start_link(?MODULE, [], []).
action(Pid, Action) ->
gen_server:call(Pid, Action).
init([]) ->
erlang:send_after(?INTERVAL, self(), trigger),
{ok, temple:new()}.
我想要做的就是把這種
handle_call({fight}, _From, Temple) ->
NewTemple = temple:fight(Temple),
{reply, NewTemple, NewTemple};
所以我嘗試
handle_info(trigger, _State) ->
land:action(self(), {fight}),
erlang:send_after(?INTERVAL, self(), trigger);
,但我得到
