Question

使用Javascript：

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

HAXE： 嘿我试着像这样定义对象：

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

但是我收到编译错误，

我该怎么办？

不知道你要做什么，但你必须实例化你的地图

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(){}

}
