Roblox is introducing new agent features to help developers plan, build and test games on its platform, the company exclusively tells TechCrunch. Roblox is improving Roblox Assistant, a plain language AI tool for game development, to help creators throughout the development process.
According to the company, AI tools that take a prompt and output a one-step solution often fail to accurately capture the creator’s original intent. That’s why we introduced an enhanced “Planning Mode” that turns your Assistant into a collaborative partner that can analyze your game’s code and data model, ask clear questions, and turn your prompts into editable action plans.
Planning mode helps developers create a plan for their game, get feedback and adjust details, finalize their approach, and implement that plan. Authors can fine-tune plans and add context before changes are made to ensure that intent is clearly reflected.
For example, if a creator tells an assistant, “Create a park minigame with a fountain and leaves where characters collect coins,” the assistant might ask what visual style they want for the park. Options include cartoonish, realistic, and fantasy. Or, the assistant might ask you how you’d like to create park assets, like fountains or foliage, and offer options like building it from scratch, using a model from the Creator Store, or a combination of both.
Once a plan is developed, Planning Mode leverages Roblox’s other AI tools while creating the game. These AI tools include two new tools announced today: mesh generation and procedural model generation, designed to speed development.
Mesh generation makes it easy to add fully textured meshes, or 3D objects, directly to your game world. According to Roblox, in the early stages of development, developers often create placeholder assets to understand how players will interact with the world. Mesh generation allows authors to quickly create 3D models without relying on low-quality placeholders.
For example, creators can ask the assistant to generate a campfire, add lights to make it more realistic, and set a night scene.
Roblox will also soon introduce “procedural models,” which will allow developers to create editable 3D models using code and assistants. The assistant understands 3D space and physical relationships, so authors can use prompts to position and scale objects based on other objects in the scene.
Dynamically adjust attributes such as the number of shelves in a bookshelf or the height of a staircase to create editable components that can be adjusted and reused elsewhere.
“With the introduction of agent capabilities in Roblox Studio, we are reducing the barrier between creative vision and execution,” Nick Tonow, senior vice president of engineering, said in a statement to TechCrunch. “Creating with planning mode and procedural generation tools is a powerful new way for creators to turn concepts into gameplay.” Assistant acts as a multi-stage co-development partner, accelerating the planning, building, and testing process so creators can bring their ideas to life faster. ”
Once planning mode is run on your plan, you can use playtesting tools to read output logs, capture screenshots, and check the design and gameplay using inputs like keyboard and mouse to identify bugs and provide feedback to your assistant so they can be fixed automatically.
“With new capabilities across Plan, Build, and Test, the Assistant is better at using agent loops to test different aspects of the game, suggest solutions, and incorporate the results into future planning loops to create self-correcting systems that become more accurate over time,” Roblox explained in a blog post.
Roblox also announced that it is working on enabling multiple AI agents to work together in parallel to perform long and complex workflows on the cloud, handling tasks such as coding, testing, and creating more realistic game characters. We also want creators to be able to seamlessly use Claude, Cursor, Codex, and other third-party tools in Roblox Studio.
