Create your custom serializable class that holds the reference to an UnityEngine.Object that implements an interface I.
The main purpose of InterfaceReference is to present a code friendly solution to reference UnityEngine.Objects with Interface I in Inspector.
The repository comes with main class InterfaceReference'I; support scripts and few attributes.
- Option 1 (readonly) now it supports Unity Package Manager so you can download by copy/paste the git url in 'Package Manager Window + Install From Git'. As said this is a readonly solution so you cannot access all files this way.
- Option 2 (classic) download this repository as .zip; Extract the files; Drag 'n' drop the extracted folder in your unity project (where you prefer).
- Option 3 (alternative) add this as submodule / separate repo in your project
- Option 4 (vintage) use the old ".unitypackage"
Multiple Components:
- For multiple components with T implementation on same gameObject by defult only the first is retrived. To assign another component that is not the first you should open two inspectors: with one locked on the object with the interface reference you can use the other to manually assign the appointed component
Code:
- The process to create your custom reference to your
interface is similar to create custom events
with UnityEvents.
Just inherit from InterfaceReference'I with your custom
serializable class where I is the interface.
- By code you can access to the interface by implicitly casting the class to T "(I)interfaceReference" or just type "interfaceReference.Interface". (see also the examples)
- Alternatively you can declare a UnityEngine.Object and use the TypeFilterAttribute (another solution). Then at runtime cast it to the interface
Inspired by (IUnified asset store and forum) (an useful asset that I bought years ago) I'd like to put me on try and present my solution to the question of how to serialize interfaces held by components (or other objects)? What is the best plug 'n' play workflow/compromises to do this?
This version is completely free and different (as implementation).
