How to install raylib-cr on Windows without errors?

Follow the MSVC or MSYS2 instructions in the README: install Crystal via scoop, run the PowerShell script, set LIB and PATH environment variables to include C:\raylib, then add raylib-cr to shard.yml and run shards install. It's a multi-step process that requires careful attention to platform specifics.

Is raylib-cr or crsfml better for 2D games in Crystal?

raylib-cr offers a simpler, more minimal API focused on ease of use, while crsfml (SFML bindings) might provide more features but with a steeper learning curve. Choose raylib-cr if you prefer raylib's philosophy of simplicity and direct control.

Can I use raylib-cr for commercial game development?

Yes, raylib is licensed under zlib/libpng, which is permissive for commercial use, and raylib-cr follows suit. However, consider the limited platform support and community size for long-term maintenance and troubleshooting.

How to add a GUI to my raylib-cr application?

Require 'raylib-cr/raygui' in your Crystal file to access RayGUI's immediate mode GUI functions. This allows adding buttons, sliders, and other UI elements directly within your rendering loop, as per raylib's documentation.

What's the performance impact of using raylib-cr vs C?

Performance overhead is minimal since raylib-cr uses direct C bindings, but Crystal's garbage collection and runtime might introduce slight latency in performance-critical loops. For most games, this is negligible, but benchmark for heavy simulations.

How to compile a raylib-cr project for Linux distribution?

Use Crystal's build tools (e.g., crystal build) to create a static executable after installing native dependencies via the Ubuntu script. Ensure all linked libraries are included, as the README outlines static linking for 64-bit Linux.

What is Raylib-cr?

raylib-cr is a Crystal language binding for the raylib game development library. It provides Crystal developers with access to raylib's complete API for creating 2D and 3D games, simulations, and multimedia applications. The bindings include both raw function calls and Crystal-friendly operator overloads for mathematical operations.

Target Audience

Crystal programmers who want to create games, graphical applications, or multimedia projects using the raylib library's simple API.

Value Proposition

Developers choose raylib-cr because it provides the simplest way to use raylib from Crystal, with minimal abstraction overhead, operator overloads for mathematical types, and support for raylib's extended modules like RayGUI and audio systems.

Overview

LibRaylib Bindings for Crystal.

Use Cases

Best For

Creating 2D games with Crystal programming language
Building graphical simulations and visualizations in Crystal
Learning game development concepts with Crystal and raylib
Prototyping game ideas quickly with raylib's simple API
Developing cross-platform multimedia applications in Crystal
Adding graphical interfaces to Crystal command-line tools

Not Ideal For

Projects targeting MacOS as a primary development or deployment platform
Teams requiring high-level, object-oriented game engines with built-in tools and editors
Applications that need extensive third-party plugins or a large, active community for support
Rapid prototyping with visual scripting or drag-and-drop interfaces

Pros & Cons

Pros

Complete Library Access

Provides raw function bindings to all raylib C functions, ensuring developers have full control over raylib's capabilities without abstraction overhead.

Intuitive Mathematical Operations

Includes operator overloads for vectors, matrices, and quaternions from raymath, making mathematical expressions more readable and Crystal-friendly.

Extended Module Support

Optional includes for RayGUI, RLGL, audio, and lighting systems allow for advanced features like IMGUI interfaces and OpenGL abstraction without extra dependencies.

Cross-Platform Compatibility

Supports 64-bit Linux and Windows out of the box with static linking, ensuring consistent performance and ease of deployment on these platforms.

Cons

Limited Platform Support

MacOS support is explicitly listed as 'Weak/Broken,' and Raspberry Pi is only a future hope, severely restricting deployment options for many projects.

Complex Installation Process

Requires running platform-specific installation scripts and manual environment variable setup (e.g., on Windows), which can be error-prone and time-consuming for newcomers.

Raw API Exposure

Only provides direct C function bindings with minimal wrapping, lacking higher-level, idiomatic Crystal abstractions that could simplify common game development tasks.
