Roblox adds agent tools

Roblox has added agent-style artificial intelligence tools to Studio that can plan, build, and test games from plain-language prompts. (about.roblox.com) The update, published April 15 by senior vice president of engineering Nick Tornow, expands Roblox Assistant with an improved Planning Mode, new mesh generation, upcoming procedural model generation, and a playtesting agent in beta. Roblox said 44% of its top 1,000 creators already use Roblox Assistant or third-party AI tools through Model Context Protocol, or MCP, to plan, build, and test games. (about.roblox.com) Planning Mode turns a text request into a step-by-step game plan instead of jumping straight to code. Roblox said the assistant can inspect a game’s code and data model, ask follow-up questions, and produce an editable action plan before making changes. (about.roblox.com) Roblox’s new build tools focus on 3D assets, the digital objects that fill a game world. Mesh Generation can create textured 3D objects directly in Studio, while Procedural Models, which Roblox said are coming soon, will let creators generate editable objects with adjustable attributes like shelf counts or staircase height. (about.roblox.com; techcrunch.com) The testing piece is aimed at a routine bottleneck in game development: checking whether a feature actually works once it is built. Roblox said its playtesting agent, now in beta, is meant to automate parts of quality assurance so creators can catch issues earlier in the plan-build-test cycle. (about.roblox.com) Roblox has been moving in this direction for more than a year. In March 2025, it launched Cube 3D mesh generation tools, and at its September 2025 Roblox Developers Conference it announced MCP integration in Studio Assistant alongside other artificial intelligence features for creators. (auganix.org; about.roblox.com) The company is pitching these tools at a platform that has grown into a large creator economy. Roblox said in its September 2025 conference post that the platform had more than 111.8 million average daily active users and that creators had earned more than $1 billion through the Developer Exchange program over the prior year. (about.roblox.com) Roblox’s own documentation already frames Assistant as a tool that can read a creator’s project and suggest or add scripts inside Studio. The new release pushes that further, from code help toward a workflow where the assistant helps decide what to build, creates assets for it, and runs tests on the result. (create.roblox.com; about.roblox.com) That puts agent features inside a mainstream game-creation platform, not just a standalone chatbot. Roblox’s pitch is that a creator can start with a sentence, review a plan, generate pieces of a world, and hand off part of playtesting without leaving Studio. (techcrunch.com; about.roblox.com)
