Developing More Hacks
In the previous post I went over LD_PRELOAD to hijack functions and created the speed hack. In this post I’m going over and understanding other hacks that LiveOverflow made i.e fly hack and teleportation hack.
Creating our Fly Hack
Like the previous hack we can just hook the World::tick() function access the global GameWorld variable and edit m_jumpSpeed and m_jumpHoldTime of our player object to create a sort of fly hack.
