Roblox is testing a tool that could accelerate the process of building and altering in-game objects by getting artificial intelligence to write the code. The tool lets anyone playing Roblox create items such as buildings, terrain, and avatars; change the appearance and behavior of those things; and give them new interactive properties by typing what they want to achieve in natural language rather than complex code. "Say I need a gleaming metal sword for an experience I'm creating," says Daniel Sturman, CTO at Roblox. "It should be really easy to create that." Sturman showed WIRED the new Roblox tool that generates the code needed to create objects and modify their appearance and behavior.
