Question

我正在制作一个socket.io游戏，而存储项目符号数据对我来说已成为一个问题。如何将项目符号对象放在项目符号对象列表的内部，即项目对象的内部，所有主要对象的列表的内部。

服务器代码：

#include <iostream>
#include <string>

using namespace std;

bool is_isomorphic(const string& input1, const string& input2)
{
    if (input1.length() != input2.length()) {
        return false;
    }

    char map[256]{};
    bool used[256]{};

    for (size_t i = 0; i < input1.length(); i++) {
        unsigned char val1 = input1[i];
        if (!map[val1]) {
            unsigned char val2 = input2[i];
            if (used[val2]) {
                return false;
            }
            map[val1] = input2[i];
            used[val2] = true;
        } else
        if (map[val1] != input2[i]) {
            return false;
        }
    }

    return true;
}

int main() {
    cout << is_isomorphic("abcd", "aabb") << endl;
    cout << is_isomorphic("abcdb", "zerte") << endl;
    return 0;
}

客户代码：

var Player = function(id) {
   var self = {
   canshot: false,
   bullets: []
   }
}
socket.on('shoot', function(data){
   if(player.canshot){
      console.log("FIre")
      player.canshot = false
      player.bullets.push({
        xV:data.xVel,
        yV:data.yVel,
        x:data.x,
        y:data.y
      });
      time = 1000/player.fireRate
      setTimeout(() => {
         player.canshot = true;
      }, time);
    }
 });
//Sends data in loop
   bullets:player.bullets,
   canshot:player.canshot

按照我在评论中表达的道理，可以将您的代码重构为如下代码，以帮助您解决此嵌套问题：

// Player Class
function Player(id)
{
    this.id = id;
    this.canshot = false;
    this.bullets = [];
    this.fireRate = 100; // whatever
|

// Bullet class
function Bullet(player, xV,yV,x,y)
{
    this.player = player;
    this.xV = xV;
    this.yV = yV;
    this.x = x;
    this.y = y;
}

// other code

socket.on('shoot', function(data){
   if(player.canshot){
      console.log("FIre")
      player.canshot = false
      var bullet = new Bullet(player, data.xVel, data.yVel, data.x, data.y);
      player.bullets.push(bullet);
      time = 1000/player.fireRate
      setTimeout(() => {
         player.canshot = true;
      }, time);
    }
 });

现在每个子弹都可以自己处理，因为它知道它属于哪个玩家，并且您可以避免所有这些玩家和子弹的嵌套

ListA内的ObjectA，ObjectB内的ListA，ListC内的ObjectB
