Roblox is introducing new agentic artificial intelligence features designed to help creators plan, build, and test games on its platform, the company exclusively told TechCrunch. The revamp of the Roblox Assistant, a plain-language AI development tool, aims to support creators throughout the entire game development lifecycle.
Nick Tornow, Senior Vice President of Engineering at Roblox, stated the launch "reduces barriers between creative vision and execution." He described the Assistant as a "multi-step, collaborative development partner" that accelerates the process from idea to reality.
Planning Mode: From Prompt to Action Plan
The core enhancement is a new "Planning Mode," which transforms the Assistant from a single-step tool into an analytical partner. It can analyse a game's existing code and data model, ask creators clarifying questions, and translate prompts into detailed, editable action plans before any changes are made.
For example, if a developer asks to "create a park mini game with a fountain and foliage where characters have to collect coins," the Assistant may ask for the desired visual style—such as cartoony or realistic—or how assets should be sourced, offering options like building from scratch or using the Creator Store.
New Building Tools: Mesh and Procedural Generation
When executing a plan, Planning Mode leverages other new AI tools announced today. Mesh Generation allows developers to quickly create fully textured 3D objects (meshes) to replace low-quality placeholder assets during early development stages.
Roblox will also soon introduce Procedural Model Generation, enabling the creation of editable 3D models with code and Assistant prompts. This allows dynamic adjustment of attributes, like the number of shelves in a bookcase, creating reusable building blocks.
Automated Testing and Future Vision
As it builds, the Assistant uses automated playtesting tools. It reads output logs, captures screenshots, simulates user inputs like keyboard and mouse actions, identifies bugs, and provides feedback to fix them automatically, creating a "self-correcting system."
Roblox also announced it is working on enabling multiple AI agents to work in parallel on complex cloud-based workflows, handling tasks from coding to creating more realistic characters. The company aims to ensure seamless integration with third-party tools like Claude and Cursor within Roblox Studio.
