This chapter does not aim to cover how to integrate your game with Apple's "StoreKit" API. It is assumed that you already have integration with "StoreKit" via a native code plugin.
Apple's "StoreKit" documentation defines four kinds of Products that could be sold via the "In App Purchase" process:
This chapter covers the first case only and focuses mainly on the downloadable content concept. AssetBundles are ideal candidates for use as downloadable content, and two scenarios will be covered:
Having separate projects for downloadable content can be a good idea, allowing better separation between content that comes with your main application and content that is downloaded later.
Please note: Any game scripts included in downloadable content must also be present in the main executable.

var download : WWW; var url = "http://somehost/somepath/someassetbundle.assetbundle"; download = new WWW (url); yield download; assetBundle = download.assetBundle; if (assetBundle != null) { // Alternatively you can also load an asset by name (assetBundle.Load("my asset name")) var go : Object = assetBundle.mainAsset; if (go != null) instanced = Instantiate(go); else Debug.Log("Couldnt load resource"); } else { Debug.Log("Couldnt load resource"); }
