codex is too cool.

It is strongly recommended that some vibe coding projects that require the operation of other professional software on this machine should be done through the codex app, not the codex cli.

The picture below is a screenshot of codex operating unrealEngine.

That’s right, I’m trying to make a little action shooter 🎮, haha.

I have been working hard with codex cli for the past two days, and I still don’t understand it.

The core is that it is stuck and cannot be seen.

I will do the hard work of moving the intermediate results.

Today I tried the computer use capability of the codex app, and sure enough it can see it by itself.

It was still too path-dependent before.

You can try some GUI-related operations with the codex app, it’s awesome!
