From Google Maps to Games: Faster A* with Differential Heuristics
Inspired by Google Maps’ instant route updates across millions of roads, the author set out to understand how to make A* scale to huge maps. After a decade of failed drafts and experimentation, they’re finally releasing an interactive guide to differential heuristics, a powerful yet simple A* optimization. The new page uses directional arrows and interactive region visualizations to show exactly when and where the heuristic helps. It’s a practical, visual resource for game developers pushing large-scale pathfinding.
Procedural Stages and Lissajous Curves: Inside Fortnite’s Daft Punk Experience
Addison Herr reveals the technical and artistic secrets behind Fortnite’s Daft Punk event, where music, math, and real-time graphics collide. He walks through building a procedural triangular lattice in Niagara, driving a constantly morphing stage, and encoding Daft Punk’s music as 3D Lissajous curves that players fly through. With insights on HLSL over node spaghetti, Houdini-assisted effects, and a Nintendo-inspired “choose your difficulty” pit mechanic, the talk is packed with ideas for ambitious interactive concerts.
🎮 From Small Games to Massive Hits
How a 4‑Month ‘Small Game’ Became a $10M Steam Hit
Code Monkey breaks down how Prism Studios turned a four-month “small game” into a projected $10 million Steam hit. By building on a proven incremental tower defense concept, adding a huge 20% twist (massive unit counts), and validating the idea with viral short-form videos, they de-risked the project early. The team then executed a textbook Steam strategy: early page, daily social posts, open playtest, demo before Next Fest, and a well-timed launch. The story doubles as a blueprint any indie can follow to dramatically improve their odds.
Designing With Feelings: Emotional Granularity in Game Mechanics
Senior game designer Adam Milkovski (11 bit studios) shows how “emotional granularity” can transform your game design. Drawing on examples from Journey, XCOM, Amnesia, Papers, Please, Frostpunk, and NieR, he breaks down how mechanics—not just story—can reliably evoke specific emotions like grief, fear, guilt, or gratitude. He explains how to choose a core target emotion, support it with contrasting feelings, and test it in playtests. The talk ends with a practical exercise for turning any random emotion into a concrete game mechanic.
🧠 Powering Next‑Gen Game Tech
Free Your CPU: Running Game Voice Safety on AMD NPUs
Developers from Data Biomes and AMD explain how to add efficient, privacy-preserving voice moderation to multiplayer games using Unreal Engine and AMD Ryzen AI hardware. Their Control Vox plugin runs voice detection, ASR, and a finely tuned toxicity classifier entirely on-device, with only a 40 MB footprint and ~10% CPU/NPU usage, letting players and devs choose which categories of speech to filter or auto-mute. AMD’s new NNEI Runtime AMD backend lets Unreal’s NNEI seamlessly offload ONNX models to the NPU, turning a 50% CPU drain into a 3% NPU blip for continuous inference workloads. The session also highlights AMD Skola for NPC training and upcoming FSR and hardware support expansions.
Inside Fortnite’s Xbox PC Port: Unreal GDK Plugins and Handhelds
Microsoft and Epic walk through a practical, end-to-end path for getting your Unreal game onto the Xbox PC app and Windows 11 handhelds. They explain why the new Microsoft GDK plugins replace the old WinGDK path, how they let you avoid duplicate cooks and missing plugin support, and how Epic used them to bring Fortnite to the ROG Ally. Expect concrete details on packaging, online services, handheld UX, and how UE 5.8 plus upcoming MSI XVC v2 will simplify builds even further.
