VisCheckCS2

External Visibility Check for CS2 via .vpk Map Parsing (Python + C++ Module)

A tool to check visibility between points in CS2 without memory hacking, using .vpk/.vphys map parsing and optimized BVH raycasting.

---

🔹 Features

• Pure external approach: No injection or m_bSpottedByMask dependency.
• Map file parsing: Converts .vphys → .opt for fast visibility checks.
• Python module: vischeck.pyd (C++ + pybind11) for easy integration.
• Performance: ~1ms per ray (CPU-dependent).

🔹 Repository Structure

1. VPhysToOpt/

   • .vphys → .opt converter (C++20).
   • Strips junk data, keeping only triangles and vertices.

2. VisCheck/

   • Python module (vischeck_module.cpp + pybind11).
   • Möller–Trumbore ray-triangle intersection.

🔹 Installation

1. Compile VPhysToOpt

• Open VPhysToOpt.sln in Visual Studio (2022 recommended).
• Build as Release x64 (ISO C++20).

2. Compile vischeck.pyd

1. Open vischeck_module.cpp in Visual Studio.
2. Configure project properties:
   • C/C++ → General → Additional Include Directories:

     C:\Users\USERNAME\AppData\Local\Programs\Python\PythonXX\include;
     C:\Users\USERNAME\AppData\Local\Programs\Python\PythonXX\Lib\site-packages\pybind11\include
     

   • Linker → General → Additional Library Directories:

     C:\Users\USERNAME\AppData\Local\Programs\Python\PythonXX\libs
     

3. Build as Release x64.

3. Usage

import vischeck
checker = vischeck.VisCheck("de_mirage.opt")  # Load map
is_visible = checker.is_visible((x1, y1, z1), (x2, y2, z2))  # Returns bool

🔹 Notes

• No pre-built binaries provided (compile manually).
• VAC-safe if used without memory hacking.
• Map files (.vphys) must be extracted via Source 2 Viewer.
