Episode 4 of the RPG Items series! After spending the first three episodes building a robust, high-performance data model, it’s time to shift our focus to the visual side of things.
In this episode, we take a step back from raw coding to look at the overall architecture of the View and Controller layers. I’ll walk you through how the system handles UI events, decouples data from visuals, and stays incredibly flexible using the MVC and Strategy patterns.
📊 VOTE ON THE NEXT EPISODE'S UI:
I’ve built two different example UIs for this framework - one based on our original series assets and one recreating the sleek UI from Arc Raiders! Head over to the community tab to vote on which one we build first:

What we cover in this episode:
* The MVC View & Controller: Splitting the logic into clean ItemContainerView and ItemSlotView components.
* The Strategy Pattern in UI: Why pushing UI events from the MonoBehavior View up to a separate Controller script allows us to reuse the exact same visuals with entirely different logic.
* Visual Previews vs. Real Data: Structuring slots to support a visual item stack vs. a real item stack - perfect for action previews and non-bound slots.
* High-Level Drag & Drop Logic: A breakdown of how the SlotController and DragController work together to handle inventory slot movement.
* The Model's Payoff: Seeing how a robust backend keeps our frontend scripts short, readable, and incredibly easy to maintain.
Next episode, we'll implement the crucial Observer Pattern using C# events to dynamically update the UI whenever our model changes. Don't forget to vote on the UI style you want to see!
