⚡ Zen Client v3

A next-generation Minecraft Bedrock Edition utility client written in modern C++23.
Engineered for performance, built with zero external dependencies (except ImGui).

---

🎯 Overview

Zen Client is a high-performance, fully modular hack client for Minecraft Bedrock Edition (Windows 10/11). Built from the ground up using C++20/23 modules (.ixx), Zen achieves both blazing-fast compilation and runtime performance while maintaining a clean, extensible codebase.

Unlike other clients that pull in dozens of external libraries, Zen relies on in-house developed tools for core functionality — signature scanning, hooking, math, and rendering are all custom-built by the Zen Development team.

✨ Key Features

🏗️ Modern Architecture

• C++23 Standard — Leverages the latest C++ features including modules, concepts, and constexpr improvements
• Module-Based Design — Every component is a self-contained .ixx module for clean separation and fast incremental builds
• Zero External Dependencies — All core libraries (Zenova, Jonathan, Paul, BigRat) are developed in-house

⚡ Performance First

• SIMD-Accelerated Scanning — AVX2/SSE4.1 optimized signature scanning with compile-time pattern parsing
• Minimal Hooking Overhead — Custom trampoline-based hooking with automatic instruction relocation
• Async Initialization — Multi-threaded startup with detailed timing diagnostics
• Link-Time Optimization — Full LTO enabled for release builds

🎮 Module System

Categorized, toggleable modules with configurable settings and keybinds

🖥️ Rendering

• BigRat — Custom ImGui backend rendering directly through Minecraft's Tessellator
• Native texture loading via Windows Imaging Component (WIC)
• Hardware-accelerated UI with proper scissor clipping

🛠️ In-House Libraries

Zen Client is built on a foundation of custom libraries developed specifically for this project:

🔍 Zenova — Ultra-Optimized Signature Scanner

// Compile-time signature parsing with zero runtime overhead
constexpr auto sig = ZEN_SIG("48 8B 05 ? ? ? ? 48 85 C0 74 ? 48 8B 00");
auto result = Zenova::find(sig, moduleBase, moduleSize);

• Hand-rolled AVX2/SSE4.1 SIMD implementations
• Compile-time signature parsing into optimized bytecode
• Automatic CPU feature detection with graceful fallbacks
• First-byte optimization for rapid candidate filtering

🪝 Jonathan — Tiny Hooking Library

// Simple, reliable function hooking
Jonathan::create(target, detour, &original);
Jonathan::enable(target);

• 5-byte relative jumps when possible, absolute jumps otherwise
• Automatic instruction-length decoding for safe trampolines
• Thread-safe hook management with atomic operations
• Support for both x86 and x64 architectures

📐 Paul — Modern Math Library

// Clean, constexpr-first math API
using namespace Paul;
Vec3f position = Vec3f::Zero();
Mat4 transform = Mat4::Identity();
Quat rotation = Quat::FromEuler(pitch, yaw, roll);

• Vector types: Vec2, Vec3, Vec4
• Matrix operations: Mat3, Mat4
• Quaternions with full interpolation support
• Geometric primitives: Rect, AABB, BlockPos
• All operations are constexpr where possible

🐀 BigRat — ImGui Bedrock Backend

Custom ImGui rendering implementation that interfaces directly with Minecraft's rendering pipeline:

• Renders through the native Tessellator for zero additional draw calls
• Proper texture management via TextureGroup
• Native scissor/clipping support
• Font atlas baked to Bedrock texture format
