ВопросI wanna understand what is the C_DOTAGamerules ?
hey guys i wanna understand what is C_DOTAGamerules and how can i get it and is it the class the handles the game data such as ( m_nHeroPickState , m_iGameMode, m_hGameModeEntity ,m_iCreepUpgradeState , m_fGoodGlyphCooldown , m_fBadGlyphCooldown )
etc.... ??

it's a structure that defines... the game's rules... such as the gamemode(all pick turbo ability draft etc), gamestate(hero selection, pregame, ingame), and all kinds of other settings. you can get it by checking xrefs to _g_pGameRules in client.dylib and then correlating that with client.dll, or by extracting it from C_DOTAGamerulesProxy which is an entity with m_designerName: dota_gamerules
what if i wanna extract the ready game id before accepting to the game it might not be through the C_DOTAGamerules OR C_DOTAGamerulesProxy but i wanna get the game id and the game players ids etc .....

earlier it could be done with protobufs but not via netchan but rather via gamecoordinator(netchan is in-match communication, gamecoordinator is out-of-match communication(such as finding matches, inventory, etc.))(they send you a lobby(CSODOTAStaticLobby or CSODOTALobby or something? don't remember) but it's currently mostly empty, used to be full of data). but they partially fixed it(they don't send that data anymore, at least normally), it's not possible anymore through naive, obvious means(or at least wasn't, last time I checked) - you'll have to explore on your own
yes. if you want an example of what you can get from the game coordinator just open the console and you'll see shit like "Received/Sending message k_EMsgBlahBlahBlah, 123 bytes"
1) hero selection is in-match communication, unrelated to gamecoordinator(basically gamecoordinator = dashboard only)
2) hero selection actually happens via input commands(something like console commands, but they get sent to the server instead of actually getting executed in the console. "dota_select_hero npc_dota_hero_antimage" for example is one such "fake console command" - if you type it into the console, it will get sent to the server(all commands, all the shit you type into the console gets sent to the server by default, unless it's an actual console command registered as such on the client)), no protobufs
try searching this forum for terms "ISteamGameCoordinator", "ProtoBufMsgHeader_t", "CGCClient"
but implementing all of that is going to be a lot more complicated than you think.
just use already existing in-game wrapper-functions for that.
again, no need to touch CGCClient directly(that would be too difficult)
see CDOTA_DB_Play::StartFindingMatch and CDOTA_DB_Play::OnAcceptMatch
(check .dylib)
just use wrapper-functions that get invoked when you click on buttons in the UI, they'll do everything you need

yes, CGCClient(game coordinator client) is responsible for managing/interacting with shared objects(shared, as in shared between the client and the server) (lobbies are shared objects too)
don't expect something that's X years old to be 100% relevant today. these members are probably still there, just at a (hopefully) slightly different offset(and yes, for lobby data you obviously need to be in a lobby) - look around in reclass(it displays RTTI) and maybe you'll find something.
but again, there are ready-made high-level wrapper functions that dota itself uses, CGCClient is relatively low-level stuff
ok i found this CDOTA_DB_Play::StartFindingMatch in the dylib but i dont know how can i get it in the actual client.dll ? its not string OR class or anything how can i find it then ?

find xrefs to it(or the stuff invoked inside of it), and all kinds of string xrefs around/inside it and correlate with client.dll
StartFindingMatch has the string xref "No gamemodes selected" inside, for example. just find "No gamemodes selected" in client.dll and hopefully the function that contains that string xref is CDOTA_DB_Play::StartFindingMatch. you can then place a breakpoint, see how it's invoked(it should be invoked by CDOTA_DB_Play::StartFindingMatch(when you click the PLAY DOTA button in the main menu) which takes less parameters and thus is easier for you to work with) etc.

client.dll "40 55 48 83 EC 20 48 8B E9 48 8D 15 ? ? ? ? 48 8D 4C 24 ? E8 ? ? ? ? 48 8B 4D 08 0F B7 54 24 ? 48 8B 01 FF 90 ? ? ? ? 84 C0 0F 85 ? ? ? ? 48 89 5C 24 ? 48 89 74 24 ? 33 F6 48 89 7C 24 ? 33 FF 48 C7 85"
this function contains everything that is the same at first glance as the function from the libclient, but I can’t say for sure that it is the same
i have renamed the function from sub_1820C6510 to StartFindingMatch
here is the signature i got using fusion plugin in ida
signature : 40 55 48 83 EC ? 48 8B E9 48 8D 15 ? ? ? ? 48 8D 4C 24
but the address of it was sub_1820C6510 and to get it by address u need to client.dll + 20C6510 in cheatengine
i installed breakpoint there in this location client.dll + 20C6510 then when i search for the game nothing fires
i just wanted to debug it to make sure that it is correct and check the argument that needs to be sent

update your dota(if you haven't already) and re-open the new dll in ida(or just don't use it at all, most of the stuff can be done directly in x64dbg or cheat engine or whatever else). the dll you analyzed is outdated
it's not 20C6510 anymore, it's 20C6530(client.dll - sha1: 377f3f21be0d9d4216f43d3755f7df6ab7ba8b0d timestamp: 1761161544(19:32:24 22 Oct 2025))
