clarity VS SteamKit

General * All data has been acquired from OpenDota, Stratz, and parsing replays using SkadiStats Clarity 2 * The numbers calculated here are based on each player's last 50 pro matches, exponentially weighted to give much more importance to recent performances * I have used 10 Cores, 5 Mids, and 10 Supports as the cut-off for what constitutes a top scoring player * I kept in the statistics for all players in addition to just the top players for your reference

Then you can create features yourself using various api (like opendota) or look for parsing github (i never used parsing tool myself, but i saved the link to this one : https://github.com/skadistats/clarity , no idea how good it is). Since smurf / cheaters are supposed to be a small fraction of all player, you'll end up with unbalanced dataset, so you'll prolly have to do semi supervised machine learning or at the very least supervised with weight.

So I actually use a couple different APIs. The reason for this is that I couldn't find a fantasy-related endpoint for the offical Dota API, and the match endpoint doesn't have all the data required for calculating fantasy points. To actually get all the required data, the replay needs to be downloaded and parsed (using tools like Clarity or Butterfly). OpenDota does this, and exposes all the relevant data in their match API endpoint.

The replays you download are that "raw data". You can parse it with something like Clarity.

So I will be making a client-side mod to show mmr changes as in the old client Upcoming data will be stored locally in the cfg folder (per account i.e. cloud synced) Wont know about matches played before adding the mod (valve went scorched earth removing data points from client.dll) But can populate previous history via an external opensource tool based on SteamKit samples

Or also you can check this or this github repositories, which emulate steam client (Or any other, there are lots of them)

Depends on what language you're using for JavaScript I think the defacto is anything Doctor McKay makes https://github.com/DoctorMcKay/node-steam-user, https://github.com/DoctorMcKay/node-steam-user etc. If you use python, I'd recommend https://github.com/Gobot1234/steam.py (I'm totally not biased). If you use C# then SteamKit is always a good option. If you use rust then SteamHelper looks interesting although doesn't support too many trading bot features

Me: Okay. I'm just going to prototype a game. Don't want to get carried away. I won't even write a game engine. I'll use Tabletop Simulator.

Friend: Sounds good. How's it going?

Me: Well. I needed to be able to debug my code. https://github.com/tts-community/moonsharp-tts-debug

Friend: Oh, neat. So your game is done now?

Me: Not exactly. I had to had in matchmaking by reverse engineering Steam. https://github.com/SteamRE/SteamKit/pull/704

Friend: Ah. Alright. Can I play it now?

Me: Nah, I was finding it hard to maintain code. I wrote a Lua code bundler. https://github.com/Benjamin-Dobell/luabundle

Friend: Sweet.

Me: Yeah, but I decided to integrate it into the official tooling. https://github.com/Berserk-Games/atom-tabletopsimulator-lua/...

Friend: I'm sure the community will be thankful.

Me: I hope so. I now run a small community of TTS developers. https://github.com/tts-community/

Friend: Right. You must be done by now.

Me: Nah, I couldn't statically type check my code. So I wrote some types. https://github.com/Benjamin-Dobell/tts-types

Friend: Seems unnecessary for a prototype, but sure.

Me: I had to write my own IDE to use them though. https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis

Friend: Right... So how'd the game going then?

Me: Oh, I'm not doing that anymore. I now consult for Berserk Games, developers of Tabletop Simulator

Friend: ...

I don't know any direct resources for learning how the Steam network works, smart people figured it out over many years and lots of reverse engineering. I just know a few programming libraries which you can use to interact with it, the most popular two being Steam-User (JavaScript) and SteamKit2 (.NET).

It's possible to do it through Steam's internal protocol, you probably want to use SteamKit2 here.
