Question

我在游戏服务器端，以60 FPS更新逻辑并以10 FPS发送数据

var PLAYER_LIST = {};

class Player {
    constructor(socket) {
        this.id = Math.random() * 9999;
        this.pressKeyAttack = 0;
        this.socket = socket;
        PLAYER_LIST[this.id] = this;
    }
    setupSocket() {
        this.socket.on("keypress", (data) => {
            if (data.key == 1) this.pressKeyAttack = data.value;
        });
    }
    send() {
        //Simple data
        //Send to this player all data from PLAYER_LIST
        var data = {};
        for (var id in PLAYER_LIST) {
            data[id] = PLAYER_LIST[id].pressKeyAttack;
        }
        this.socket.emit("data", data);
    }
    update() {
        if (this.pressKeyAttack == 1) {
            //do something
        }
    }
}

io.sockets.on("connection", (socket) => {
    new Player(socket);
});

setInterval(() => {
    //Logic update
    for (var id in PLAYER_LIST) {
        PLAYER_LIST[id].update();
    }
}, 1000 / 60);

setInterval(() => {
    //Send data
    for (var id in PLAYER_LIST) {
        PLAYER_LIST[id].send();
    }
}, 1000 / 10);

示例客户端，当任何玩家按[Space]时，所有其他玩家都将看到该玩家的动画。

var PLAYER_LIST = {}; //all player

for (var id in PLAYER_LIST) {
    if (PLAYER_LIST[id].pressKeyAttack == 1) {
        //run animation
    }
}

socket.on("data", (data) => {
    for (var id in data) {
        PLAYER_LIST[id].pressKeyAttack = data[id];
    }
})

document.onkeydown = function(e) {
    // Player.pressKeyAttack = 1
    if (e.keyCode == 32) socket.emit("keypress", { key: 1, value: 1 });
}

document.onkeyup = function(e) {
    // Player.pressKeyAttack = 0
    if (e.keyCode == 32) socket.emit("keypress", { key: 1, value: 0 });
}

我的问题：

例如：我是一名游戏玩家（称为Player_A），还有一些其他玩家。当Player_A如此快地上下按[Space]时，其他播放器无法从Player_A接收数据（pressKeyAttack = 1），因为循环发送数据运行10 FPS（每100ms发送一次），Player_A.pressKeyAttack等于1并返回0 50毫秒。

看起来像：

at 0ms: Player_A.pressKeyAttack = 0;

at 20ms: Player_A.pressKeyAttack = 1; //Player press down

at 50ms: Player_A.pressKeyAttack = 0; //Player press up

at 100ms: Loop Data Run - Player_A.pressKeyAttack = 0.

实际上它曾经是1。如何解决此问题？

如何在Node.js中发送真实数据？
