BitCore

BitCore is a lightweight, high-performance C# library for bit manipulation and tuple conversions, optimized for real-time applications like Unity3D. It offers extension methods for packing and unpacking numeric types (byte, sbyte, short, ushort, int, uint, long, ulong) and utilities for bit operations and binary string parsing.

Features

• Bit-level operations (e.g., SetBitAt, PopCount, BitString).
• Tuple packing/unpacking (e.g., PackToInt, UnpackToBytes) in big-endian order.
• Aggressive inlining for .NET 4.6+ builds.
• Unity3D-ready with no external dependencies.

Installation

Unity Package Manager (UPM)

1. Open Unity, go to Window > Package Manager.
2. Click + > Add package from git URL.
3. Enter: https://github.com/astrum-forge/bit-core.git.
4. Click Add.

Usage

Bit Manipulation

using BitCore;

int value = 0b00001010; // 10
value = value.SetBitAt(2); // 0b00001110 (14)
int bitCount = value.PopCount(); // 3

Tuple Conversions

using BitCore;

(byte, byte, byte, byte) bytes = (0x12, 0x34, 0x56, 0x78);
int packed = bytes.PackToInt(); // 0x12345678
var unpacked = packed.UnpackToBytes(); // (0x12, 0x34, 0x56, 0x78)
