NonAllocFlagGenerator

An efficient solution for flag checking in C# and Unity

Benefits of NonAllocFlagGenerator

  • Solves the boxing issue of the default HasFlag method
  • Improves performance by minimizing garbage generation
  • Easy to use

Installation

  1. Open the Package Manager in Unity (Window > Package Manager)
  2. Add the NonAllocFlagGenerator package using the following Git URL:
    https://github.com/KBluePurple/NonAllocFlagGenerator.git?path=/Plugins#master

How It Works

NonAllocFlagGenerator uses C# Source Generators to automatically generate efficient extension methods for enums marked with the [Flags] attribute. Here's a detailed breakdown of the process:

  1. Source Generation: At compile time, the generator scans your codebase for any enum types decorated with the [Flags] attribute.

  2. Extension Method Creation: For each flagged enum it finds, the generator automatically creates specialized extension methods that perform flag checking operations without allocating memory on the heap.

  3. Compile-Time Processing: All the code generation happens during compilation, which means:

    • There's no runtime overhead for generating the methods
    • The generated code is type-safe and checked by the compiler
    • You get IDE support like IntelliSense for the generated methods

  4. Zero Allocation Design: The generated extension methods use bitwise operations instead of boxing/unboxing, ensuring that no garbage is generated during flag checks.

Usage Example

[Flags]
public enum PlayerState
{
   None = 0,
   Idle = 1 << 0,
   Walking = 1 << 1,
   Running = 1 << 2,
   Jumping = 1 << 3,
   All = ~0
}

var currentState = PlayerState.Idle | PlayerState.Walking;
// Efficient flag checking using NonAllocFlagGenerator
if (currentState.HasFlagNonAlloc(PlayerState.Idle))
{
    // Handle Idle state
}
if (currentState.HasFlagNonAlloc(PlayerState.Walking))
{
    // Handle Walking state
}

With NonAllocFlagGenerator, you can easily check flags while writing readable code without compromising performance. Apply NonAllocFlagGenerator to your project today and experience efficient flag checking!
