What is valorant-external-framework?

Valorant-External-Framework is a C++ codebase described as an educational reference for game hacking theory and reverse engineering research, targeting the game Valorant. The repository is presented as a framework for studying how external game overlays and kernel-mode drivers work in practice. The code demonstrates three categories of concepts. The first is an ESP overlay (short for Extra Sensory Perception in gaming contexts, meaning visual information drawn on screen about other players), including bounding boxes, skeleton rendering, health bars, and distance indicators. The second is an aimbot demonstrating memory-based angle interpolation with adjustable field of view, hitbox targeting, and recoil compensation. The third is a skinchanger showing how in-game item appearance can be altered by modifying internal game structures. The technical foundation uses a kernel-mode driver, which is software that runs at the most privileged level of the operating system, allowing it to directly read and write another process's memory. This bypasses the normal boundaries between applications. The overlay uses ImGui rendered over DirectX 11 or DirectX 12. Communication between the driver and user-space application uses IOCTL, a standard Windows mechanism for driver communication. The described tech stack is C++20 running on Windows. The README states the project is for educational purposes, game hacking theory, and reverse engineering research. It is classified as a reference for understanding the technical concepts involved in external game modification.
