オブジェクトの配列を ActionScript に渡す方法


概要


本ドキュメントでは、UnrealScript と ActionScript 間でオブジェクトの配列を受け渡す方法について、その概略を示しています。

UnrealScript から ActionScript へ


UnrealScript
  /** Item struct */
  struct Items
  {
    var string ItemName;
    var string ItemType;
    var string ItemDesc;
  };
  
  var array<Items> Inventory;
  
  function SetUpInventory()
  {
    local byte i;
    local GFxObject DataProvider;
    local GFxObject TempObj;
    local GFxObject RootMC;
  
    RootMC = GetVariableObject("_root");
  
    DataProvider = CreateArray();
  
    for (i = 0; i < Inventory.Length; i++)
    {
      TempObj = CreateObject("Object");
      TempObj.SetString("ItemName", Inventory[i].ItemName);
      TempObj.SetString("ItemType", Inventory[i].ItemType);
      TempObj.SetString("ItemDesc", Inventory[i].ItemDesc);
      DataProvider.SetElementObject(i, TempObj);
    }
  
    RootMC.SetObject("inventory", DataProvider);
    ShowInventory();
  }
  
  function ShowInventory()
  {
    ActionScriptVoid("showInventory");
  }
  

ActionScript
  var inventory:Array = [];
  
  function showInventory()
  {
    for (i:Number = 0; i < inventory.length; i++)
    {
      trace("Name: " + inventory[i].ItemName + " | Type: " + inventory[i].ItemType + " | Description: " + inventory[i].ItemDesc);
    }
  }
  

ActionScript から UnrealScript へ


UnrealScript
  function ListInventory()
  {
    local GFxObject Item;
  
    // Method 1
    // These lines return the name, type, and description of the inventory item stored at element 0 of the inventory[] array in the Flash file.
    `log("Item Name: " @ RootMC.GetObject("inventory").GetElementMemberString(0, "ItemName"));
    `log("Item Type: " @ RootMC.GetObject("inventory").GetElementMemberString(0, "ItemType"));
    `log("Item Description: " @ RootMC.GetObject("inventory").GetElementMemberString(0, "ItemDesc"));
  
    // Method 2
    // This version first caches a reference to the GFxObject{} found at element 0 of the inventory[] array.
    Item = RootMC.GetObject("inventory").GetElementObject(0);
  
    `log("Item Name: " @ Item.GetString("ItemName"));
    `log("Item Type: " @ Item.GetString("ItemType"));
    `log("Item Description: " @ Item.GetString("ItemDesc"));
  }
