Use Codex to shape game architecture and animation blending

A game builder had Codex handle core architecture and improve animation transitions by reading engine docs and wiring in merging logic.

What they did
While working on a game, a commenter asked Codex to take on some foundational architecture tasks. Codex also went into the engine documentation on its own and added animation merging so movement changes would flow more cleanly. Some of the structure came from explicit requests, but the agent filled in other useful pieces without being told step by step.
How it went
The game ended up with a stronger underlying setup and animations that no longer looked choppy. The commenter did not share any measurements or specific bugs, only that part of the work still depended on direct instructions.
Tips
This worked best after about 1.5 years of using Codex, along with a growing set of instructions and techniques. For a similar task, ask the agent to outline its plan first and check the result in a test scene or existing test suite before you accept the changes.

Try it yourself with Codex

In [repo path] for my game, review the [engine name] docs for animation handling, then improve animation blending/merging for [character, system, or scene]. Before you edit code, tell me the plan and what files you expect to touch. After making changes, run the relevant tests or a sample scene, then stop and wait for my approval before you do anything irreversible or final, such as submitting a pull request or deleting files. Summarize what you changed and any tradeoffs at the end.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
