[IAP] IDE에서 IAP테스트를 하고 싶을 때

NullReferenceException: Object reference not set to an instance of an object
UnityEngine.Purchasing.UIFakeStore.InstantiateDialog () (at Library/PackageCache/com.unity.purchasing@3.1.0/Runtime/Stores/FakeStore/UIFakeStore.cs:175)

 

 

코드에는 Prefab을 Instantiate하도록 넣어놨으면서 prefab은 구성요소로 안넣어놨음.

Resources폴더의 UIFakeStoreCanvas.prefab 파일 없음

최신으로 업데이트 하기.

본인의 경우 특정 IAP버전에 겨우겨우 최적화를 해놓았기 때문에 이렇게 못함

프리팹이 있기만 하면 됨.

IAP 샘플 프로젝트를 받아서 내부의 프리팹을 복사해서 넣어줌.

 

 

GitHub - sassembla/Autoya: thin framework for Unity.

요거넣으니까 됨. 이거 받아도 된다.

 

 

UIFakeStore.cs

간단한 구조이기 때문에, 코드 보고 그냥 GameObject이름 맞춰서 만들어도 될 것 같음.

/// <summary>
		/// Creates the UI from a prefab. Configures the UI. Shows the dialog. 
		/// </summary>
		private void InstantiateDialog()
		{

			Canvas dialogCanvas = UIFakeStoreCanvasPrefab.GetComponent<Canvas>();

			// To show, and to configure UI, first realize it on screen
			m_Canvas = Object.Instantiate(dialogCanvas);

			// TRICKY: I support one dialog at a time but there's a delay between a request
			// to the UI system to destroy a UI element and the UI system completing the destruction.
			// To avoid conflicts with partially destroyed dialogs hanging around too long we add a 
			// custom behavior to the scene explicitly to notify me when the UI has been destroyed.

			LifecycleNotifier notifier = m_Canvas.gameObject.AddComponent<LifecycleNotifier>() as LifecycleNotifier;
			notifier.OnDestroyCallback = () =>

				m_EventSystem = new GameObject("EventSystem", typeof(EventSystem));
				m_EventSystem.AddComponent<StandaloneInputModule>();
				m_EventSystem.transform.parent = m_Canvas.transform;
			}

			// Configure the dialog
			var qt = GameObject.Find(m_ParentGameObjectPath + "HeaderText");

			denyText.text = m_CurrentDialog.CancelButtonText;
		
			// Populate the dropdown
			GetDropdown().options.Clear(); // Assume it has defaults prepopulated
			foreach (var item in m_CurrentDialog.Options)
			{
