在 ActionScript 3.0 中访问 "global" var - AIR 应用程序

Question

在 AIR Mobile 应用程序中，我有以下代码：

import character.*;

var player_1 = new characterObject("Player 1");
var player_2 = new characterObject("Player 2");

在包中 class:

package character {

    public class characterObject extends MovieClip {
    public var characterName: Number;
    public var playerCounter: Number = 0;

        public function characterObject(myName: String) {
            characterName = myName;
            playerCounter++;
        }

    }

我可以在 player_2 对象距离内访问 player_1.playerCounter 属性吗？仅当 total_player 时，我才需要增加玩家的价值（我想创建的 var 作为 player_1.playerCounter 的总和+ player_2.playerCounter + player_n.playerCounter ...) < of x .

Answer 1

我会创建一个向量来保存 characterObject class 之外的字符实例。然后你可以参考当前金额的向量长度。

var characters:Vector.<characterObject> = new Vector.<characterObject>();

characters.push( new characterObject("Player 1") );
characters.push( new characterObject("Player 2") );

trace( characters.length ); // 2

Answer 2

坏主意。

你可以尝试下一步

package character {
   public class CharactersModel extends Object{
      private var _chars : Array = [];
      public function addCharacter(char : characterObject) {
         _chars.push(char);
      }

      public function getChars() : Array {
          return _chars;
      }

      public function getCharByName(name : String ) : characterObject {
      //select from array and return
      //use it instead of null
      return null;
      }
   }
}

并像这样更新 characterObject

private var _model : CharactersModel;
 public function characterObject(model : CharactersModel ,myName: String) {
    _model = model;            
    characterName = myName;
    playerCounter++;
    model.addCharacter(this);
  }

  public function getOtherChar(name : String) {
    return _model.getCharByName(name);
  }

最后

import character.*;
var model : CharactersModel = new CharactersModel();
var player_1 = new characterObject(model ,"Player 1");
var player_2 = new characterObject(model ,"Player 2");
