From what I understand, every local match that is not a private room displays "BOT: {HERO_NAME}" (match id: 0) and every match with an id, even if it's with bots, displays "Private Room".

I think it will be possible to create a bot detection with this information. I'll implement later and validate.

This one is a little more difficult. But I'll research if I can get the information directly from Steam RPC.

Currently I use Dota's Game Integration service, which is nothing more than a big JSON with lots of information. I still haven't found a way to detect a game with bots from this data. I believe that seeing this information directly from Steam RPC could be a solution.

[andsfonseca]

Do you have any links about this? I never looked to see if it's possible to get this information.

This one is a little more difficult. But I'll research if I can get the information directly from Steam RPC.

I was working on a project similar to yours and researching the topic.

Advantage of using GSI: you don't need to log into Steam every time. With Steam RPC you either have to enter Steam Guard code every time or use another account to monitor status. Also, GSI has much more information.

But Steam RPC translates directly into Discord RPC (and it also has the "Main Menu", "Main Menu (Idle)", "In lobby" states).

I can't link any additional information on this though. ApexRPC was like a reference project to me, and the rest of stuff came from manually testing and logging results from different manipulations.

I still haven't found a way to detect a game with bots from this data

I suspected this might be a problem.

I believe that seeing this information directly from Steam RPC could be a solution.

This would require user to log into Steam, I think, and wouldn't get any advantages. Unless Steam SDK can provide this functionality, of course. If this is the case, I don't think it's worth it then.

Although IIRC you can get Steam RPC status from a player even if you are not on the player's friends list. So in theory it should be possible to make a bot/proxy which would check a person's status.

Another potential solution would be looking at the players list in the match (similar to what 9kmmr bot does). I didn't have prior experience with GSI, but I would assume that bots would have something suspicious in their data, e.g. Player->SteamID. I think this should be the best solution.

[andsfonseca]

You're right, having to save steam login information might be a little out of scope.

This is the output I get when I'm playing with bots:

Could "map.matchid": "0" pop up in any other game aside from a botmatch or a local lobby? I think this could be a decent endicator, if it only shows up for botmatches.
