Episode 2 of the RPG Items series dives into the core data structure of our architecture: the ItemContainer.
Instead of jumping straight into a rigid "Inventory" class, we’re building a highly generalized, abstract container. This single foundation will eventually power everything from player inventories and banks to world loot chests and equipment slots.
We also focus on modern C# performance standards, bypassing standard heap allocations in favor of pooled arrays for memory-efficient operations.
What we cover in this episode:
* Item Container interface and abstract class: The foundational building block that the whole system relies on.
* ArrayPool to minimize allocations and garbage collection spikes.
* Ref Keyword Optimization: Writing values directly into arrays using reference variables.
* Smart Stacking Logic: Implementing a two-pass algorithm that fills existing item stacks before empty slots.
* Overriding Max Stacks: Making our system flexible enough to allow dynamic container-specific modifiers.
We're building this step-by-step from a simple foundation, layout out the groundwork before we introduce our transaction-based system in a later episode.
