Descripción
Strategy Inventory System (SIS) is a highly flexible, slot-based inventory plugin built for multi-unit strategy games, including RTS, squad-based, and tactical titles. It also works seamlessly in first-person and third-person RPGs.
Built on a Component + Interface architecture, SIS is designed to be non-intrusive and easy to integrate into existing projects. You do not need to modify your original character inheritance hierarchy, making the system suitable for both rapid prototyping and large-scale multiplayer production.
