Let’s assume the following **Actor** , which has **ComponentA** and **ComponentB**.

```auto
          Actor
            |
     ---------------
     | |
ComponentA ComponentB

```

Let’s assume **ComponentA** needs to keep **ComponentB** updated about a value, in case this value ever changes. **ComponentB** would then need to adjust some of its own values in response.

And let’s also assume, I wanted to solve this problem using **Delegates** — keeping both of the **Components** loosely coupled and modular as they in theory should be. No hard references.

I know about the different types of **Delegates** and their usage and I have created my fair share of **Components** over the last few months while learning. So I should be familiar with the basics needed to solve this problem.

Which brings me to the question of the correct or at least most common approach to this scenario with a minimum of coupling and a maximum of modularity.  
Should I forward the **Delegate** from **ComponentA** to **ComponentB** via the owning **Actor** to prevent direct coupling between the two **Components** or is there a better approach I am not aware of?
