This simple system can be used to help you avoid using Monobehaviours in Unity whenever you don't need one. Most of the times, Monobehaviours are used simply for their update loop.
Implementors of the IUpdateHelper interface can provide a common update loop that can be shared accross several objects implementing IUpdateDelegate. A common update loop as opposed to several smaller objects containing update loops will result in an increased performance in your project.
Additionally, your code will be more testable, as you will no longer have a Monobehaviour dependency where there previously was one.
- Create an implementation of IUpdateHelper. You can use the UpdateHelperMonobehaviour as a starting point. This implementation needs to be placed in your scene. It uses its update loop to call IUpdateDelegate.Update() on an internal list of delegates.
- Provide your IUpdateHelper throughout the code, using any means of Dependency Injection.
- Classes interested in having an update loop provided, can call IUpdateHelper.RegisterDelegate(this) on construction.
- Classes using the update helper should call IUpdateHelper.UnregisterDelegate(this) when they are disposed (if following the IDisposable pattern) or no longer used.
