How to stop moving and cancel current spell?

[oiramario]

1. when aplayer's position is in spell range by using CTM move to target, how to stop moving? I've tried move to own position for stop moving, however it will turn around because delay.
2. how to interrupt the current casting in case of emergency?
any advice and hints are welcome, thanks!

If you're implementing combat as a ranged class, typically no real player ever moves into range by right click attacking.
For ranged combat classes, I use GitHub - recastnavigation/recastnavigation: Navigation-mesh Toolset for Games in order to generate a path to the mob.
Then using CTM move to position I follow the path, and once in range do a click to move to my current position in order to stop walking.

On the note of canceling spell casting, I found a string reference of "Usage: CancelSpellByName(name)" which you could probably reverse.
It's obfuscated in the tbc prepatch though not sure about vanilla classic, so might be difficult to reverse.

Additionally, can you please provide some information on how you are implementing your bot's update logic.
My bot update logic depends on the most recent update tick to indicate when to run again, and I have had lots of success with this implementation
Below is some code/psuedo code to clarify how my bot handles update ticks

uint64_t last_update = 0;
uint64_t next_update_delta = 0;

uint64_t timeSinceEpochMillisec()
{
	return std::chrono::duration_cast<std::chrono::milliseconds>(std::chrono::system_clock::now().time_since_epoch()).count();
}

HRESULT PRESENT_CALL Present(IDXGISwapChain* thisptr, UINT SyncInterval, UINT Flags)
{
        // Always draw as often as we can
        draw();


        if ((timeSinceEpochMillisec() - last_update) >= next_update_delta) {

                // Client::Update returns a uint64_t representing delay in milliseconds until executing another update tick
		next_update_delta = Client::Update();
		last_update = timeSinceEpochMillisec();
	}

}

In order to move and fight, I built a traffic network with multiple path points. During the battle, the character is allowed to leave the main path when necessary and return to the traffic network after the battle.

From 18179, I found CGInputControl::StopMovementAndTurning and CMovementShared::StopMove maybe that's a better way to stop moving, however I dont know how to call them, so what's your suggestion?

Do you have any experience with CancelSpellByName, CancelSpellById?

1.13.5.36325 is not obfuscated, you can found it here GitHub - notscimmy/wow_classic_dumps: Binary dumps of World of Warcraft Classic...for educational purposes of course if you do not have it yet. Thanks for @scimmy.

Hook Present is a bad idea because people use multi-thead renderring in moderm engine. WindProc is much better.

I use C/S pattern for update logic like Sendmessage.

wow -> server
you -> client
client request or send command to server, and wait for response from server then to continue.

Would you tell me how to dump vmt?

Hm I'll investigate about your suggestion of using WndProc, I haven't had any threading issues executing in dx11's present so far.
For dumping virtual method tables, at runtime I print an object's vmt address and then just find the address in ida and start reversing from there.
I'm sure there is a more efficient way, but I'm only using like 5 vmt calls so I haven't invested much time into them.

There are too much renderer: dx9/10/11/12, ogl, ogles(arm64 now supported). And, fps of renderring(30/60/144) is different with logic(the main thread maybe is 30 locked that's enough). WndProc it's could be sure in the main thread that's why it's my chosen.
Even you hook present, you could also respone one request per frame, that's what I mean: C/S. We should not take up too much thread time.
