的Javascript HAXE成员变量的对象

Question

的Javascript：

function TeamSelection(player_id) 
{ 
    var playerInfo = new Object(); 
    playerInfo["info_" + player_id]; 
} 

HAXE： 嘿，我想这样定义对象，以便：

class TeamSelection 
{ 
     var playerInfo : Map<String>; 
     public function new() {} 
     public function changeField() 
     { 
      playerInfo.set("info_" + player_id, player_name); 
     } 
} 

但是我得到一个编译器错误，

我该怎么办？

不知道你是triying做什么，但你必须实例化您的地图

class TeamSelection 
{ 
     var player:Player; 
     // i don't know why you don't stock your players directly.. 
     var playerInfo : Map<String,String>= new Map();// has to be instanciated 
     public function new() { 

     //create your player 
     player= new Player(); 
     player.id=1; 
     player.name="bob"; 

} 
     public function changeField() 
     { 
      //make use of string interpolation 
      playerInfo.set('info_${player.id}',player.name); 
     } 
} 
class Player{ 
public var id:Int; 
public var name:String; 
public function new(){} 

}
