Don't know what Asset User Data is? It's effectively extra data you can add to (generally) any Asset or Component (or any object that implements IInterface_AssetUserData, and then can query upon at runtime. This is great for implementations where you only want to define the data once on the asset and not on a per actor basis (i.e. puzzle games).
The engine doesn't expose this to Blueprints, so this plugin does the work for you via the BPAssetUserData class and AssetUserDataFunctionLibrary.
- Add this plugin to your project and compile it
- If it isn't already, enable it and restart engine:
- Create a subclass of the BPAssetUserData class:
- Add some properties to your new blueprint:
- Add an instance of your Asset Data Blueprint to the Asset User Data array in an asset or component:
- Use the "Get Asset User Data" node to query asset data on reference to asset (or component):
The add and remove nodes should mostly be used by editor utilities and assigned once. The add node will only add a single instance of the specified class. The getters are perfectly fine to use anywhere.
