Dear script kiddies and Hackers, I present to you Explosive Bullets in C++ for SPRX.
I googled it and never found it for SPRX so here.
But before, here's a reminder.(you can skip this)
I been quite busy with life.
However, I intend to stay active. I will try to share almost everything that I know because this can be ported to various different Games and platform.
If you need help hit me up. I am very friendly and easy going if you got the skills to pay the bills. I can't really help people with RTM(C#) on the other hand I kickass at C++, PPC,IDA,etc.
I only mod Black Ops!
Now back to the Release. As I mentioned earlier I don't have much time so the code I'm sharing today is very messy and could be optimised.
I asked 01cedricv2 to take a look if he does I'll update the thread but if not you guys can pitch in too.
The code doesn't freeze and is commented on my pastebin. Enjoy
it would be cool if someone shares the other weapondef as I don't have time to dump their offsets...
