Phaser's Game Agent, Box3D, and EVE's engine goes open source

Two currents ran through this week. Prompt-to-playable went mainstream, and a surprising amount of production-grade engine code went open source.

Phaser Game Agent: one sentence in, playable game out

Phaser Studio launched Game Agent, a hosted service that takes a one-sentence game description and handles design, code, art, sound, and testing, then publishes the result to a shareable browser link. It runs on a new engine with a verb-based API designed around how an agent reasons, and it covers 2D sprite games, vector worlds with destructible terrain, and simple 3D. You pick an art style and a model tier and pay with credits, so cost scales with how much you iterate. Treat the first output as a prototype to inspect, not a finished game.

Box3D: Erin Catto goes 3D

The creator of Box2D released Box3D, an MIT-licensed 3D physics engine written in C17 with cross-platform determinism and a SIMD contact solver. He calls it an alpha, but it is already in production in s&box and several serious projects. Box2D earned two decades of trust in 2D; this is the same philosophy in 3D, with no vendor lock-in, for free.

EVE's engine goes open source

Fenris Creations finished open-sourcing Carbon, the engine framework behind EVE Online, releasing more than twenty modules under MIT, including the Trinity renderer and the Destiny physics and pathfinding tech behind EVE's massive space battles. The economy and server systems stay closed. Production-proven MMO-scale simulation code is now free to study and reuse.

VectorayGen is free forever

JangaFX re-released VectorayGen, its node-based vector-field generator for GPU particle effects in Unreal Niagara and Unity VFX Graph, with the license checks removed: as is, for free, for eternity. Version 1.04 is final and will not get updates, but a previously paid VFX authoring tool is now a zero-cost part of the pipeline.

Meta's Pocket experiment

Meta quietly launched Pocket, an experimental app for creating and scrolling playable AI-generated mini-games in a feed, currently available only in Brazil. Meta says it may never launch everywhere. The interesting part is the thesis: a platform of this size betting that prompt-to-playable is a consumer content format, the same idea Phaser is selling to developers.

Also worth your time

Neural4D launched AI 3D Agent, a single prompt panel for 3D, image, and video generation with base meshes in under 90 seconds and a free tier. Unity Hub's new-project screen now has a Use AI Assistant checkbox, a small change that signals AI-by-default in the engine. And Pipe It, a pipe-drawing plugin for Unreal with snapping, auto brackets, and swappable kits, hit feature complete and is heading to Fab in the coming weeks; the demo pulled thousands of reactions from environment artists.
