Injecting commands

[EightyVice]

What i mean if there is a game
and we want to make the player shot from third party program like if there is a button if we press on it it make the player shot
so we change the entire function by function injecting in c++
or how?
any ideas?

I don't know what you mean. Do you mean making a program to control the game?

Yea that what i mean!

At that point you're more or less talking about developing hacks.

lol , just for making some mods in my game and a complement to my multiplayer mod in game called [Duke Nukem: Manhattan Project] you made me tell the name before i release it
but i really need the answer because there is not any answer in google

vc-mp is a hack itself, its injecting in vice city game.

Use a debugger, find the offset that shoots (try using breakpoints) and either jmp to it or push the current offset into the callstack and call it. Never done this before so don't know which one you'd use for this.

All multiplayer mod [that without source code] are memory hack and network stuff.

that seems easy to be done in cheat engine but the problem is in injecting it in c++ .
that assembly sucks xD

You're not wrong.

Ok guys is there a way to inject the commands or that scripts in the memory , and getting the real offset like finding a needle in the hay :v
i think we need to ask @maxorator !

You aren't supposed to guess the offset. You are supposed to actually find it.

There's more to it than just finding an offset. You can mirror the behaviour produced when the shooting key is pressed (trigger the same function with the same parameters) and that'd probably be the easiest way to accomplish it.

Do you know how to use a debugger to find out the address of the function where you are supposed to jmp to? I tried using a debugger today and didn't understand it at all.

I don't think I'm supposed to talk about stuff like this since it could easily lead to development of hacks, but there are numerous sites that explain things like this on the internet, I'm sure you'll find the answer if you dig deep enough.

@EK.IceFake I used IDA but I can't even get the address

Well, YouTube filled up with useless videos only for game health and so on, but injecting function I didn't find that I spent 3 weeks in that no hope
I though VCMP forum will help , you know why? And you too shadow
