Zig DLL in Unity 👨💻, Unreal Mass ECS 🎮
⚙️ Engine Tech & Performance Boosts
Curious If a Zig DLL Can Speed Up Your Unity Game?
Learn how to boost Unity performance by offloading hot loops to a Zig-based native plugin. git-amend builds a small distance-squared function in Zig, exports it with a C ABI, and wires it into C# using `[DllImport]`. Benchmarks show Zig crushing a plain C# loop and even beating single-threaded Burst, though Burst’s parallel Jobs system ultimately dominates. You’ll also get guidance on when Zig makes sense for real projects, like pathfinding, procedural generation, or custom physics.
Scaling Gameplay with Unreal’s Mass: Data-Oriented ECS in Practice
An Epic Games engineer digs into how Unreal’s Mass Entity framework brings data-oriented ECS to real-world gameplay, not just boids demos. He explains how traditional actor/component code wastes cache, and shows concrete patterns like using entities as events, splitting characters into many small entities, and keeping processors tiny for parallelism. The talk also demos the Mass Debugger’s query-based breakpoints and live inspection. It all culminates in a huge robot battle, with tens of thousands of AI-driven, physics-simulated entities running every frame.
🎭 Characters, AI & Gameplay Systems
From Life Makeover to Silent Whispers: High-End UE5 Characters on Mobile
Discover how Arkso Games built a next-gen Unreal Engine 5 character pipeline powering its new title Silent Whispers. The team details its move from UE4 to UE5, adopting Substrate materials for believable fabrics, a scalable MegaLights system for densely lit environments, and targeted mobile optimizations including cached shadows and hybrid SSR + ray-traced reflections. By extending MetaHuman with custom expressions, body correctives, and clothing interaction controls, they achieve high-end, story-driven characters across PC and mobile without sacrificing frame rate.
From Sinus Curves to Smart Hordes: Designing a Co‑op AI Director
A veteran designer shares the step-by-step evolution of an AI Director that controls pacing, difficulty, and enemy composition in co-op PvE games. Starting from a basic time-based curve, the system grows to track actual player intensity, adjust spawns by skill level, and spend a combat budget on pre-authored enemy packs. Ambient “inhabitants” keep the world feeling alive and gently steer players forward. Designer-facing curve overrides and “curve stitching” make scripted objectives blend seamlessly with procedural encounters.
