so the whole purpose of this mess is to call a function within the context of the main thread right?

why not enumerate the threads in start time order.

write your bytecode to some arbitrary memory location.

hijack the context and profit?

Im just confused why everyone is hooking endscene to call stuff like scriptexecutbuffer.

Threading issues... Have fun calling FrameScript_ExecuteBuffer if you hijack the main thread while it is in the middle of anything with Lua.

^ This.

Plus, hooking EndScene gives you a decent 'pulse' callback for your bot.

I must just be lucky then ;p

haven't had anything happen yet as far as a crash is concerned

Race conditions are sporadic by nature.

Hey!

First of all, thanks for writing iHook, it's great, I'm noob enough to have a problem with it

My goal was to code a program in c# which warns the user, if his random dungeon group is ready.
Using your attached example, I managed to hook with the Wow.exe, tested some API stuff (got them from here) (Google <3) .
My problem is, that I can't manage to get "GetLFGProposal" to work.

Hook.DoString("lfg = GetLFGProposal()");
Console.WriteLine(Hook.GetLocalizedText("lfg"));

I tried this ^ but it doesn't return anything.

What I noticed is that "proposalExists" is a flag, not a string, still I don't know how to handle this problem. I tried with multiple syntaxes, etc, none working for me. I'm sure this is possible somehow, because the rest of the API is working flawlessly, (primitive stuff like dancing etc.) I'm just stuck with this.

Thanks in forward!

Hey

Try this(untested):

Hook.DoString("proposalExists, typeID, id, name, texture, role, hasResponded, totalEncounters, completedEncounters, numMembers, isLeader = GetLFGProposal();");
Console.WriteLone(hook.GetLocalizedText("propsalExists");

Hook.DoString("proposalExists, typeID, id, name, texture, role, hasResponded, totalEncounters, completedEncounters, numMembers, isLeader = GetLFGProposal();");
Console.WriteLone(hook.GetLocalizedText("propsalExists");

Still doesnt return anything

P.s: I found another way: I check the minimap displaywith GetMinimapZoneText(), start a loop, scan it again until it changes, and if it changes, play sound etc. Don't know if it works, but it should, in theory. Yet I want to know how this GetLFGProposal(); works.

[MaiN]

..just do:

Hook.DoString("if GetLFGProposal() then proposalExists = \"1\" else proposalExists = \"0\" end");
bool proposalExists = Hook.GetLocalizedText("proposalExists") == "1";

Hook.DoString("if GetLFGProposal() then proposalExists = \"1\" else proposalExists = \"0\" end");
bool proposalExists = Hook.GetLocalizedText("proposalExists") == "1";

Not working

[MaiN]

Not working

Then you are doing something wrong. I think GetLocalizedText has issues with bools, but it definitely doesn't have issues with strings.

[-Ryuk-]

Not working

Are you using the correct addresses?

It could be that the method I used in the dll is now broken :P

Three chances can cause 'doesnt work' or 'doesnt return anything'. 'DoString()', 'GetLFGProposal()' or 'GetLocalizedText()' work incorrectly. I think it is helpful to debug them individually.

e.g.

1. Execute the code below IN GAME, instead of using 'DoString()', to check what happened on 'GetLFGProposal()'

/run print(GetLFGProposal())

2. If 'GetLFGProposal()' works fine, try C# code below, and check the result in game:

Hook.DoString("print(GetLFGProposal())");

3. Check anything else, etc.
