General Issues and Bug Reporting

Summary

Hi, your Assistant says info is current as of the June, but also says it’s dataset is only up to build v31.20.

recently: If you ask it anything about entity/components it will hallucinate like crazy and the conversation will permanently devolve into worse gibberish each response.

Things such as inventing classes that dont exist, and code that could no way compile become common once it gets stuck in this spiral:

Foo:ai_interaction_component = Agent.GetTransform().Translation
if (Foo = MyTag):
    Print("Agent has tag"!)

What build is supposed to be in it’s current dataset? Do you update it each new public release?

This week it is Hallucinating a bit less, and it says it’s version is 35.10 (May 2025), which sounds more likely.
I’m guessing it’s GPT; It always had this tendency to throw any old fake answer rather than saying it doesnt know… but then says it doesnt know about real things until you ask it a different way.

Whats the radius of a player hitbox?

“The Player hitbox dimensions is not documented”

How do you recommend avoiding the player in sweephits?

"…+Forward*PlayerHitbox… (defined as 50cm, but it’s recommended 65.0-70.0 to avoid edge-cases.)

Great for a convo, but c and js devs know claude wastes less time for code.
