[Diablo 3] Click to move?

[diablothree]

Lots of good progress happening in other threads with regard to memory reading, but how many people are successfully interacting with the client and moving the hero? Are you calling functions directly with injection, sending mouse/keyboard signals, or...?

[MartyT]

Yeah. I've embedded a .NET Api that can be used to interact with the game. Very similar to ISXWoW.Net - just without the Innerspace stuff and the lavishscript crap.

e.g.

Me.UsePower(SNOPowerId.Walk, Me.X + 10.0, Me.Y + 10.0, Me.Z);

Thanks. I've tentatively decided to implement a similar API but staying mostly out of process, by injecting a small code cave hanging off EndScene that calls the in-process equivalent of UsePower(). I haven't stumbled across anything like that in IDA yet; is it really as simple as "use power a directed at vector b" for most of the actions a bot would do (walk, attack, interact)?

EDIT: Getting closer, I've found the call chain for using powers but still trying to find the best method to hook up to. Here's the chain of methods I'm seeing (first method calling the next, and so on):

0x008144F0 - A message loop handling WM_* events
0x009B8790 - Appears to be related to click handling
0x009B84C0 - Looks up a handler function in an array of objects containing function pointers
0x00942BB0 - Determines what power to use, among other things
0x00941860 - Starts getting into the meat of using the power. Looks like here or somewhere further down is a good place to call in?


A few useful powers:

Witchdoctor_PoisonDart (1930D)
Axe_Operate_Gizmo (7545)
Axe_Operate_NPC (7546)
Walk (777C)

And... 0x941640 is the winner.
