RaylibUE plugin seamlessly bridges Raylib's powerful 2D/3D drawing API with Unreal Engine's intuitive Blueprint system. Draw shapes, text, lines, textures and more, directly on your game viewport via transparent overlay, no code barriers.
- Educational Stating Point: Ideal for teachers and students, learn with Raylib's simplicity alongside Unreal Engine's depth, from basic shapes to 3D models.
- Raylib Fidelity: 50+ Raylib draw functions as Blueprint nodes (e.g., DrawCircle, DrawText, DrawModelEx) with exact parameters for 1:1 learning.
- Independent Rendering: RaylibUE uses Raylib graphics API (OpenGL), running independent of Unreal Engine’s graphics settings, and fully compatible with DirectX 11, DirectX 12 and Vulkan projects.
- Non-Intrusive Overlay: Renders to an independent overlay window atop the Unreal Engine game viewport, syncing on resize, move, maximize or minimize, while preserving Unreal Engine input, focus and performance.
- Command Buffer: Queue and update render draw commands with handles, reorder, purge by type, or bulk-set commands for real-world renderer pipeline practice.
| Category | Highlights |
|---|---|
| 2D Basics | Pixels, lines, circles, rects w/ gradients/rounding |
| Text | Dynamic fonts, texture fonts, codepoints, pro transforms |
| 3D | Spheres, cubes, cylinders, models w/ wires |
| Textures | Billboard, NPatch, pro UVs |
| Utils | Camera, FPS counter, grid, ray |
- Blueprint Chain: All nodes return OutShape pins, allowing direct connection to Update nodes for zero-friction development.
- C++ Friendly: Static calls, e.g.,
URaylibUEBPLibrary::DrawPixel(10, 10, FLinearColor::Red, ID, Shape);.
#include "RaylibUEBPLibrary.h"
FRlDrawText rlText;
URaylibUEBPLibrary::DrawText("Hello RaylibUE!", 100, 100, 24, FLinearColor::Yellow, rlText);If you are using Unreal Engine 4.27.2 or 5.6.1 and don't want to build the plugin from source, you can go to the
Releases page and download the ready-to-use binary version.
Just unzip the file into your project folder and open your .uproject.
The engine will enable and load RaylibUE, you can start using it immediately.
- git clone https://github.com/darknessfx/RaylibUE.git
- Create a new Unreal Engine C++ Project named YourProject.
- Create a new folder named Plugins at YourProject/.
- Copy RaylibUE to YourProject/Plugins/ folder.
- Regenerate project files. (right-click YourProject.uproject and Generate Project Files).
- Open YourProject.uproject and reply Yes to buld the project.
Dependencies :
- Windows (WinAPI overlay)
- Unreal Engine 4.25+ and 5.0+ (Tested on 4.27.2 and 5.6.1).
- Raylib library is bundled.
- Visual Studio or VS Code to build from source, more information at Unreal Engine: Setting Up Visual Studio and Setting Up Visual Studio for Unreal Engine.
- Open Level Blueprint.
- Event BeginPlay, add a new node: Raylib DrawText.
- Set DrawText node to Text "Hello Raylib", PosX 30, PosY 30, FontSize: 64, Color: Green
- Play in a New Editor Window (PIE).
Next Step: See the image below to make your text grow each frame.
