オブジェクトの配列を ActionScript に渡す方法

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"));
}
