Osu! Game state API about osu

[huoyaoyuan]

Sounds an useful idea.
I used to write an tool getting osu's state, but it's using window title, and can only get very little information.

Could do this quite easily with the existing IPC code, or with minor changes to it.

I think IPC it's too difficult

I think this is a good idea, but not for your idea of the mouse color changing to red if you can miss a note. Something like that might make it way too easy to create cheating tools and possibly give some players an unfair advantage. Instead, maybe external tools could be able to request info such as score, combo, accuracy, song progress, key counts, hp, current song, and game mode (essentially, anything on the hud); and they could listen in on events such as start, finish, fail, pause, resume, retry, quit, hit note (with info on the timing and score), and maybe the other activities shown in Bancho (like editing, modding, listening)

Definitely should be a thing, but closing the issue to clean things up for now (only keeping active problems rather than potential features).

Can this be taken into consideration again?
It would help build bots, that display "Now Playing" information in OBS or Twitch.
Other bots might appear too.
Otherwise we would have to resort to reading from raw memory addresses, or patch the osu!laser code and risk not being able to submit scores.

Btw: gosumemory currently reads from raw memory addresses in regular osu.
gosumemory provides a ton of information from inside osu!. It also has a PP overlay.

This is still tracked under #13011 and attempted at #12274.
