Question

我正在尝试使用画布上的vanilla-js和websocket的Django-Channels构建一款多人，快节奏，侧滚动的平台游戏，称为Star Jumper。我无法通过服务器获取足够的消息以使延迟可播放。发送到服务器的消息包括按下/向上键，鼠标单击和定期对帐。为了解决问题，我只关注定期对帐，在consumers.py中的redis服务器上设置了两个计数器。py-（1）从客户端收到的对帐和（2）发送到相对客户端的对帐。在游戏中有2个玩家的情况下，服务器的已收到消息计数器开始以每秒10个左右的速度（超过2个玩家，每秒总共20个）超过发送的消息计数器。我希望我做错了什么，Django Channels每秒可以处理20条以上的消息，但我很困惑。

下面的相关代码repo is here很高兴澄清/发布更多。在仓库中，“ multiplayer.html”模板具有我的动画循环和套接字流量管理。

在“ StarJumper / templates / multiplayer.html”中

let socket = new ReconnectingWebSocket(ws_path)
function Reconcile() {
    socket.send(JSON.stringify({
        "command": "reconcile",
        "game": {{ game.id }},
        "client_now": global_now,
        "current": {
            "x_pos": world.player.x_pos,
            "y_pos": world.player.y_pos,
            "vy": world.player.vy,
            "color": world.player.color,
        }
    }))
}

在“ StarJumper / app / consumers.py”中...

async def receive_json(self, content):
    game = await get_game_or_error(content["game"], self.scope["user"])
    command = content.get("command", None)
    if command == "join":
        await self.join_game(content)
    elif command == "reconcile":
        msg_ct = cache.get("msg_ct")
        cache.set("msg_ct", msg_ct + 1, timeout=CACHE_TTL)
        await self.reconcile_group(content)
    # other commands stripped out for this post

async def join_game(self, content):
    # other join stuff stripped out for post
    cache.set("msg_ct", 0, timeout=CACHE_TTL)
    cache.set("thru_ct", 0, timeout=CACHE_TTL)
    cache.set(game.group_name + "." + self.scope["user"].username + ".client_now", 0, timeout=CACHE_TTL)

async def reconcile_group(self, content):
    game = await get_game_or_error(content["game"], self.scope["user"])
    if cache.get(game.group_name + "." + self.scope["user"].username + ".client_now") < content["client_now"]:
        await self.channel_layer.group_send(
            game.group_name,
            {
                "type": "reconcile.client",
                "username": self.scope["user"].username,
                "current": content["current"],
                "game": game.group_name,
            }
        )
        cache.set(game.group_name + "." + self.scope["user"].username + ".client_now", content["client_now"], timeout=CACHE_TTL)

async def reconcile_client(self, event):
    if event["username"] != self.scope["user"].username:
        thru_ct = cache.get("thru_ct")
        cache.set("thru_ct", thru_ct + 1, timeout=CACHE_TTL)
        msg_ct = cache.get("msg_ct")
        print(msg_ct, thru_ct, msg_ct - thru_ct)
        await self.send_json(
            {
                "type": "reconcile",
                "username": event["username"],
                "current": event["current"],
            }
        )

如何获得Django频道以处理更高的消息频率？
