Sera.Union For Unity

sera-net sera-net/Sera.Union-for-Unity 2

Generates type-safe Tagged Unions in Unity using C# source generators. Define union types with a simple interface template, and the package automatically creates optimized struct implementations with memory-efficient overlapping for unmanaged types and classes. Includes pattern matching support and comprehensive equality/comparison operators.

Generate Tagged Union using source generator

  • All unmanaged types will overlap
  • All classes will overlap
  • Other types will be tiled

Example

[Union]
public readonly partial struct Union1
{
    [UnionTemplate]
    private interface Template
    {
        int A();
        string B();
        bool C();
        (int a, int b) D();
        void E();
        List<int>? F();
        (int a, string b) G();
    }
}

if (u is { Tag: Union1.Tags.A, A: var a }) { }

if (u is { IsA: true, A: var a }) { }

if (u.IsA)
{
    var a = u.A;

UniTyped UniTyped is a source generator that allows typed access to data such as SerializedObjects, material parameters, tags and layers. rucchoT4 Templates T4 Templates enables Unity developers to generate C# code from template files (.tt) using Microsoft's T4 text templating language. Author templates mixing text blocks with control logic, and the Editor automatically processes them to produce codeā€”similar to Mustache or Go's html/template. Supports openupm installation with comprehensive documentation and scripting API reference. faster-gamesZBase.Foundation.Data A tool to export ScriptableObject database from either Google Spreadsheet or CSV by utilising cathei/BakingSheet and C# Source Generator. Zitga-TechZBase.Foundation.FixedArrays ZBase.Foundation.FixedArrays uses C# source generators to create fixed-size arrays, eliminating heap allocations and improving performance for time-critical game code. Ideal for scenarios requiring predictable memory patterns, stack allocation, and reduced garbage collection overhead in performance-sensitive systems. Zitga-Tech
