Calling a function in Remote Thread

[saimoth]

Hey guys,

I have been trying to find a guide that explains how I can call a function within a RemoteThread, well call it properly I mean. I have written a LUA Unlocker and use Macro's to automate the game but I'm assigning a macro to a button, changing the macro "string" on the fly and pressing the button the run it. This works fine but its obviously very lame spamming button clicks and I would rather call the RunMacro function internally instead. I have no problem creating a remote thread and writing the ASM, etc, I'm just struggling to find the proper RunMacro(args??) function in the info dump, unsure about what arguments I'd need to pass, and also not 100% on how to deal with the function returning to my remote thread. I have been away from programming for a little while and probably just being a noob. Can anyone share some advice or point me to a guide that can offer me some help without sucking eggs.

I'm playing 3.3.5 release

Thanks, Wes

After a bit of reversing, it's DoString() that I'm trying to call. I have tried a lot but can't seem to get it to work with a RemoteThread. Does it have to be called from the main thread?

Yeah it does, you CAN call it from other threads but you will get really unreliable crash behaviour because LUA is not thread safe

All sorted, Casting away just nicely from the main thread. It does seem very weird to see actions happening without any input at all. Simple things please simple minds, huh! Thanks

Lua is thread-safe, the C functions registered by WoW on the other hand, may not be. And there's quite a difference in that so just remember it.
