EDIT: Title should read: [HELP] Calling an "inprogram" function with an injected DLL.

Ok, I know of a few function locations in a game I play (move, use skill, start quest, use item, gethp/mp, etc), but I'm not sure how exactly I'd go about calling them.

The GetHP/GetMP are simple to call, because they don't take any parameters (they just return an integer value), so I can simply typedef them in, and then do

if they are class methods you have to use inline assembly

example

class test
{
public:
void func1(int);
}

test testinst;

you have to get testinst and then

__asm
{
push myint
mov ecx, testinst
call func1
}

Read up on Calling Conventions, http://www.codeproject.com/cpp/calling_conventions_demystified.asp

Then check the code for there functions, and figure out what the calling convention is. Then prototype the functions with the proper macro.

Aww thanks nog!! I was looking for something just like that!

Hopefully I'll be able to get it to work now ^_^.

What game are you doing this with? This reminds me of botting for RuneScape - so easy because you can use the Java methods in the game for everything (once you find them).

It's for FlyFF.

When nForce released his trainer ages ago, I was able to decrypt the .offs files he used (which contained addresses/pointers his trainer used), and update them.

I doubt it.

He's been threatened with two lawsuits now I think! It's not worth the risk for him.
