Why This Matters
This article highlights the complexity of building a flexible and scalable ARPG game engine, emphasizing the importance of treating build customization as a compiler-like process. By transforming source content into runtime data through a structured pipeline, developers can manage intricate skill and item interactions more efficiently, ultimately benefiting both the development process and player experience.
Key Takeaways
- Treat build customization as a compiler pipeline to manage complex interactions.
- Precompute and cache derived data to simplify runtime skill resolution.
- Structured data transformation improves scalability and reduces special case handling.
ARPG buildcraft looks like a content problem until the combinations start piling up.
The examples here are excerpts from a Zig ARPG game engine where skills, supports, items, and runtime rules all need to compose.
At first each rule seems harmless:
this support adds damage
this support makes projectiles pierce
this item makes spell damage apply to melee
this status adds a temporary stat
this affix gives the pack more speed
this unique changes a rule
Then the combinations show up.
