Algebra

The Origami Algebra crate is a library that provides algebraic primitives for Dojo-based games. It offers efficient implementations of mathematical structures and operations commonly used in game development.

Overview

The Algebra crate focuses on providing fundamental mathematical structures and operations that are essential for game development. Its primary scope includes:

• Vector operations
• Matrix operations
• Basic algebraic computations

The crate is designed to work seamlessly with the Dojo engine and other Origami crates.

Installation

To add the Origami Algebra crate as a dependency in your project, you need to modify your Scarb.toml file. Add the following to your [dependencies] section:

[dependencies]
origami_algebra = { git = "https://github.com/dojoengine/origami" }

Make sure you have dojo installed and configured in your project.

Features

The crate currently implements a 2D vector (Vec2) with various operations:

struct Vec2<T> {
    x: T,
    y: T
}

Key features of Vec2 include:

• Construction: new and splat methods
• Dot product calculation
• Swizzle operations (xx, xy, yx, yy)
• Mask-based selection

Example usage:

let vec2a = Vec2Trait::new(1, -2);
let vec2b = Vec2Trait::new(-3, 4);
let a_dot_b = vec2a.dot(vec2b);  // -11

Conclusion

The Origami Algebra crate provides a solid foundation for mathematical operations in Dojo-based games. It offers efficient implementations of 2D vectors with various utility functions. As the crate evolves, more features and mathematical structures may be added to support a wider range of game development needs. For the most up-to-date information and usage examples, refer to the crate's source code and any accompanying documentation in the Origami repository.
