A raylib binding for Beef programming language

Raylib-Beef

raylib-beef is a Beef wrapper library for Raylib 3.7, a simple and easy-to-use library. In combination with the benefits of the Beef programming language, making games is pure satisfaction!

Attention! These bindings are still in development. Bugs may occur. You can download this library with binaries from the Release page!

OS Support is limited to Windows right now. I am only able test this library on Windows at the moment.

What is done

• Bindings for:
  • raylib.h
  • raymath.h
  • rlgl.h (partly)
  • Easings.h

Important notes

• there are no bindings for text manipulating methods
  • Beef already has custom methods for text manupulation
• rlgl bindings are partly done

TODO:

• Rewrite examples in Beef
• finish rlgl.h bindings

Quick Start (using Beef IDE)

1. Download raylib-beef.zip FROM RELEASE PAGE and extract raylib-beef folder from that zip file to: C:\Program Files\BeefLang\BeefLibs
2. Right-click on your workspace and select Add from Installed and choose raylib-beef

3. Add raylib-beef as a dependency of your project

4. Write some code:

using System;
using static raylib_beef.Raylib;

namespace YOUR_NAMESPACE_HERE
{
	class Program
	{
		public static int Main(String[] args)
		{
			let text = "Hello from Beef! Hope you have a good day!";

			SetConfigFlags(.FLAG_WINDOW_RESIZABLE);
			InitWindow(800, 600, "Hello world");
			SetTargetFPS(60);

			while (!WindowShouldClose())
			{
				BeginDrawing();

				ClearBackground(.(52, 52, 52, 255));

				var x = (GetScreenWidth() / 2) - (MeasureText(text, 35) / 2);
				var y = GetScreenHeight() / 2;

				DrawText(text, x, y, 35, .LIGHTGRAY);

				EndDrawing();
			}

			CloseWindow();
			return 0;
		}
	}
}

5. Profit!

Static linking

By default linking is set to dynamically link to Raylib. You can change that by selecting different raylib-beef project configuration in Workspace settings. You can select from DebugStatic and ReleaseStatic.

Then set your app project build properties to this:

Contribution

I'll be glad for any reported issues & pull requests

Notes

• any contributions apart from bugfixes need to be placed in src/Extensions
  • this will separate additional helper functions from bindings
  • for example if you want to add some cool method for Vector3, you will create Vector3.bf in src/Extensions/Types and add that cool method to existing Vector3 type by using extensions statement

raylib-beef's Issues

IsWindowFullscreen() should be of type bool, not void

Linux - Not Finding Raylib Beef

I am not sure if this is an issue with this library or Beef. No matter what I do I get:

ERROR: Type could not be found (are you missing a using directive or library reference?) at line 2:14 in /home/joseph/Documents/beef-game/src/Program.bf
using static raylib_beef.Raylib;
             ^^^^^^^^^^^

It seems like Beef cannot parse the library correctly. Here is a zip of raylib-beef inside of the example you provided with flags on my end: https://drive.google.com/file/d/1l1yKDCufm7vB8m8zG_ykqykLvpR4Qdza/view?usp=sharing

Here is the repo:

git clone --recurse-submodules https://github.com/joseph-montanez/beef-game.git

undefined reference to `rCloseWindow'

Both on Windows and Linux has this is undefined using the pre-built Raylib releases:
https://github.com/raysan5/raylib/releases

If change it back to CloseWindow, it works fine.

raylib-beef/src/Raylib/Core/Windowing.bf

Line 16 in ca09fed

[LinkName("rCloseWindow") /* linker fix */]

I think this is because you tried to compile this on your own and Raylib has issues with the Windows API when being included.

Error in Type RenderTexture2D

Worked out there is an error in the definition of id in the RenderTexture2D type (at least on the Windows platform)

unit id; needs to be unit32 id;

The values of the member types are set incorrectly as it currently is.

Thank you.

Update to 4.5

Any chance to see an update to raylib version 4.5 soon?

add a License

Please add a License for these bindings.
Personally I would like MIT or Zlib.
(btw. Raylib uses the Zlib-License)

IsWindowFullscreen() should be of type bool, not void

Types > Color.bf > ToString function causes error

raylib-beef/src/Types/Color.bf

Line 52 in 0fe15bc

return new String..AppendF("{} {} {} {}", r, g, b, a);

Beef version 0.42.4 raises error on this line: Expected '(' or '['

Downloaded and installed latest release of raylib-beef but the error persists.

Statically linking, Dublicate Symbol error

There is a dublicate error regarding CloseWindow() in user32 and the fix for it does not work in the static build version of the project.
For debug there is a fix by simply specifiying x64DLL in the additional link flags instead of x64.
This does not seem to work for releasee though

Some notes for Linux

OK, so I decided to use this library with linux. But, as with many other things it didn't work right away. So, I've decided to write this as a note for others who might want to do the same.

1. Install raylib (duh!)
   The binaries for raylib in the release don't work on linux. Luckily, raylib is quite easy to get-just follow the instructions here.

2)Get rid of Windows dependencies in the binding
There are 4 Windows.IntBool s in Types/PhysicsBodyData.bf. I replaced them with int32 to maintain the size of the struct, but this might have broken something in the physics system-NOT TESTED.

3)Add linker flags to the BeefProj.toml file of YOUR project - not the library.

[Configs.Debug.Linux64]
OtherLinkFlags = "$(LinkFlags) -lraylib -lglfw -lGL -lopenal -lm -pthread -ldl"

Adding this should solve any linker errors, and the project should now compile and run.

LoadImage / LoadTexture not working properly

Hi. Thanks for this project. I was playing around with it a bit, and noticed that methods related to texture and image loading aren't returning proper "Image" and "Texture2D" structs. I mean the methods LoadImage, LoadTexture, LoadImageRaw etc.

Texture loading works fine when loading models with LoadModel, but when trying to load image files directly the returned structs are populated with invalid data. I have checked to see if the structs defined on Beef side match with the Raylib, and they seem fine. Parameters passed to the function looks right too. So I couldn't understand what the problem might be. I hope you might have an idea.

Here is the returned Texture2D data :
