引用编号的变量和数组

Question

I am pretty new to AS3 and am trying to get an advanced inventory system going. I have 3 players and 3 classes: PlayerStats1 , PlayerStats2 , and PlayerStats3 . Inside each of these classes I have an array. This array contains the inventory for each player. The arrays are all named inventory . I also have a variable that determines whose inventory is opened. This variable is just called turn . Now what if I wanted to find out and display what was in Player2's inventory slot 5 (the fifth value in PlayerStats2.inventory )? How would I go about doing that with a simple code? Something like gotoAndStop(PlayerStat + turn.inventory[4]); . Of course the code probably looks a lot bigger than that.

Answer 1

Here is an example

class A {

    private var playDict:Dictionary = new Dictionary();

    public function addPlayer(playerId:int, player:PlayStats):void {
         playDict[playerId] = player;
   }

   public function getInventory(playerId:int, invertoryIndex:int):Object {
        var player:PlayStats = playDict[playerId] as PlayStats;

        if (player) {
           if (player.inventory) {
               return player.inventory[invertoryIndex];
           } else {
               return null;
           }
        } else {
            return null;
        }
   }

}

PlayStats is base class of PlayStats1, PlayStats2, PlayStats3. PlayStats1, PlayStats2, PlayStats3 could add target objects to its own invertory

public class  PlayStats {

   public var inventory:Array = [];
}
