我目前正在开发一个小的 dungon 爬虫。今天我尝试实现本地多人游戏模式......当我的duengon创建时，它还会在每个房间中创建一些敌人，大多数时候总共有大约100个敌人。首先我做了播放器部分，看起来像这样：

gameScreen.player.update();

    //Update position
    if(gameScreen.player.networkPosition.x != gameScreen.player.position.x){
        //Send the player's X value
        PacketUpdateX packet = new PacketUpdateX();
        packet.x = gameScreen.player.position.x;
        network.client.sendUDP(packet);

        gameScreen.player.networkPosition.x = gameScreen.player.position.x;

    }
    if(gameScreen.player.networkPosition.y != gameScreen.player.position.y){
        //Send the player's Y value

        PacketUpdateY packet = new PacketUpdateY();
        packet.y = gameScreen.player.position.y;
        network.client.sendUDP(packet);

        gameScreen.player.networkPosition.y = gameScreen.player.position.y;

    }
    if(gameScreen.player.netState != gameScreen.player.state){


        PacketUpdateState packet = new PacketUpdateState();
        packet.state = gameScreen.player.state;
        network.client.sendUDP(packet);

        gameScreen.player.netState = gameScreen.player.state;

    }

所以它应该只在玩家改变他的位置时发送数据包更新。在那之后，我实现了一个可加入的播放器。连接正常，一切都很好，直到我移动播放器对角线。比加入的玩家滞后很严重。首先我认为那是因为我的播放器每秒移动 200f 像素。但是当我每秒做 5 个像素时，它也会滞后：/ 我不知道为什么。这是我的玩家移动代码： 

           if(Gdx.input.isKeyPressed(Keys.A) && moveDirections[0]){ 
               position.x -= Gdx.graphics.getDeltaTime() * 200f;       

               state = 1;

           }
           if(Gdx.input.isKeyPressed(Keys.D) && moveDirections[1]){
               position.x += Gdx.graphics.getDeltaTime() * 200f;    


               state = 2;
               //System.out.println(currentState);
           }
           if(Gdx.input.isKeyPressed(Keys.W) && moveDirections[2]){ 
               position.y += Gdx.graphics.getDeltaTime() * 200f;           

               state = 3;
               //System.out.println(currentState);
           }
           if(Gdx.input.isKeyPressed(Keys.S) && moveDirections[3]){ 
               position.y -= Gdx.graphics.getDeltaTime() * 200f;

               state = 4;

           }

有谁知道，为什么它会滞后？或者一个想法如何找到问题？那是我第一次使用 kryonet :/ 感谢您的关注 :)
