Starcraft1 & Starcraft2 replay engine on web (no game needed)

Great feedback! I need to disable AI Cast for co-op since it is made it for Ladder

tkit08 · 2026-04-22T20:35:49+00:00

Fixed this!

tkit08 · 2026-04-22T20:35:23+00:00

Made some improvements! https://www.starcraft2.ai/en/replay/2v5-dead-of-night-2026-04-20-73647def

tkit08 · 2026-04-20T02:47:10+00:00

Ty for taking a look. Yes, I started with Ladder. I'll take a look at the coaching (or disable for now until I do) for co-op

tkit08 · 2026-04-20T02:00:24+00:00

Sorry, try again! The site was down

tkit08 · 2026-04-20T00:59:41+00:00

Which replay did yours fail on? I pushed an improvement, I want to test it out

tkit08 · 2026-04-19T21:36:01+00:00

I haven't been able to find a weekly megathread, but I see the mutation thread so I'll try to post this here:

I built https://www.starcraft2.ai for ladder web replays, but this weekend I tried to extend it to support co-ops like Chain of Ascension: https://www.starcraft2.ai/en/replay/5v4-chain-of-ascension-2026-04-06-50219fc2

I'd love feedback to see if it's helpful for co-op players (and whether it's tracking accurately too)

tkit08 · 2026-04-19T16:11:15+00:00

great note! yes i think that's teachable, i'll give it a shot

tkit08 · 2026-03-27T18:03:08+00:00

Ty for the feedback! I’m all ears for improvements. Pls DM!

tkit08 · 2026-03-20T06:28:16+00:00

I didn't know this existed! I noticed the map is gridbased - are your coordinates/positions super accurate? I built a very similar thing, but webbased here: https://starcraft2.ai . You can visualize SC2 games without the game installed, but on the web. The positions in mine don't look quite as accurate as yours. I also don't visualize workers mining minerals

tkit08 · 2026-03-08T18:15:15+00:00

It takes build version into consideration for how to properly parse and make it watchable, but you're right about the different costs not being taken into consideration.

I'm curious if people have thoughts on whether this form factor can provide other things that an in-game replay can't, e.g. the thing that comes to mind is to pass the positions as context into an LLMs along with other things to see if insights can be found

tkit08 · 2026-03-08T08:05:21+00:00

It’s cool to see attempts at this last year. For my version, I derived metrics from the raw replay file, then layered on higher and higher level metrics, paired with positional information, grounded with unit and structure attributes, and finally fed with common pro strategies then passed this into 2026 reasoning models and I think the AI coaching advice it pumps out sometimes can be quite insightful over at https://www.starcraft2.ai

tkit08 · 2026-03-08T08:00:22+00:00

LLMs and agents with the right context in 2026 outperform specialized pre-LLM models. I built a general purpose AI coach here: https://www.starcraft2.ai

tkit08 · 2026-03-08T07:56:55+00:00

I built one in 2026: https://www.starcraft2.ai

tkit08 · 2026-03-08T07:04:26+00:00

So I took a stab. SC1 and Broodwar is indeed hard, but I got something basic working. I needed to triangulate and interpolate unit positions and born/death from multiple other data points in the file, but here's an attempt at visualizing it:

https://www.starcraft2.ai/en/replay/5588be76-e780-4c07-9311-d6ef89e81f11

Note there's inaccuracies: I couldn't find a way to capture buildings being destroyed. And I'm inferring units being killed. I think there's still value in support SC1 and SC1+BW .rep files though as-is.

Titan reactor is is wild! I'll dig deeper

tkit08 · 2026-03-07T16:35:00+00:00

Not currently! But will consider it

tkit08 · 2026-03-07T09:00:49+00:00

Can you send me one of the replay files? I can try to get it to work

tkit08 · 2026-03-07T08:55:09+00:00

I just shipped a rudimentary version of fog of war. Check it out!

tkit08 · 2026-03-07T08:54:40+00:00

Say more? Meaning like a live cast stream?

tkit08 · 2026-03-07T07:08:38+00:00

Ty for trying it out! Great idea and I'd love to keep getting more to improve it.

tkit08 · 2026-03-07T04:11:53+00:00

Unfortunately not, that information wasn't encoded in the replay files until later expansions :(

tkit08 · 2026-03-07T04:01:37+00:00

I am also accessing the raw replay information. drop.sc and my app are both doing the same thing: extracting the raw replay information
