OMG I CAN'T IMAGINE THIS RN. THANK Y'ALLL SO MUCH

@Creastien This needs wayyy more attention. Awesome stuff!!

@austinGENEreeve @ImmatureGamer How's the latency?

@WarforgeXP We're on the same boat! I tried to give Codex a chance lately, but it never delivers the way Opus 4.6 does. I really don't know what they did to ChatGPT, it used to be good on general information, but has degraded a ton and seems to always steer off.

oof

Claude code source code has been leaked via a map file in their npm registry!

You could do this before as every object is basically a bunch of text. So in theory, you could've written a script that takes in an object's textual representation -> modifies its properties and duplicates -> returns the final text of all generated objects then paste it yourself in the editor. However, It's great to see it being integrated into the editor.

That's a big system 🫦

@mtxtun Auto leave is a must. Feels weird not being in freeplay in 0.1s after the ball touches the ground

[VukeFN @vukefn]

@giovauefn Looks very nice!

[VukeFN @vukefn]

Setters only do something when you write to them directly. Live variables watch all their dependencies and update automatically, even if a dependency three layers deep changes something you never manually connected.

On top of that, you get batching, auto-reclamping, and await/upon/when baked in. Different concepts!

[VukeFN @vukefn]

🧠 Live Variables will change how you write Verse code.

❌ No more manual callbacks.
❌ No more forgotten updates.
❌ No more "wait, why is the UI showing 0?"

Verse is getting reactive programming baked into the language

Everything you need to know 👇🧵

@dummblond Reactive

[Tim Sweeney @TimSweeneyEpic]

This is one of the most exciting features coming to the Verse language: reactive programming that “just works”!

[VukeFN @vukefn]

@TimSweeneyEpic Hey Tim 👋

[VukeFN @vukefn]

I break down Verse and UEFN features like this every week! From language deep dives to things you can actually use in your maps.

If this thread saved you from mass-updating variables at 2am, you know what to do.

Follow @vukefn so you don't miss the next one.

Got questions about live variables? Drop them below, I'll answer what I can.

[VukeFN @vukefn]

Live variables aren't released yet, but they're coming.

When they drop, you'll be able to:

❌ Eliminate manual state syncing
🔨 Build reactive UI with zero callbacks
⌨️ Write game logic that reads like intent, not plumbing

Bobby can finally rest.

Until then, study the docs. You'll want to be ready.
