raylib-goplus's Introduction

Raylib Go Plus is an improved Go bindings for the video game library Raylib

This library is a work in progress and still new. We are always looking for improvements and help translating the bindings. Any cross-platform testing is most welcome too.

Big thanks to the original Go Bindings by Gen2Brain as they served as a basis for my bindings and helped me solve some tricky c problems :)

Additional thanks to the SolarLune discord and Raylib discord for helping me out and their invested interest.

Installation

Use the go get command to fetch the latest version: go get github.com/lachee/raylib-goplus/raylib

You are required to have all the dependencies for Raylib too. Specifically (if you are on windows), Mingw-w64.

Its that simple! Once you have fetch the resource, be sure to include it and get going!

package main
import r "github.com/lachee/raylib-goplus/raylib"
func main() {
	r.InitWindow(800, 450, "Raylib Go Plus")
	for !r.WindowShouldClose() {
		r.BeginDrawing()
		r.ClearBackground(r.RayWhite)
		r.DrawText("Woo! Raylib-Go-Plus! Now with ++", 20, 20, 20, r.GopherBlue)
		r.EndDrawing()
	}
	r.CloseWindow()
}

Building / Updating Raylib / Contribution

If you wish to build and update raylib, the project comes with a useful converter. To run the converter, you need the goimports tool. It can be installed by running the command go get golang.org/x/tools/cmd/goimports. Make sure you update the source files in raylib/ and update the raylib-convert/headings.txt headings (this tells the converter what to export). Once that is done, simply run ./build.sh.

You can run the converter on Windows by using Git Bash (included with Git for Windows).

I am happy for any contributions. This is a big project with over 477 functions! Its likely I have missed something or something doesn't work right for a particular platform (I only test on Windows).

NOTE: All contributions to code within _gen.go files will be rejected! Those additions must be made within a raylib-convert/manual/ go file, with the function name as the file name.

Unloadables

There is an experimental feature in this library called "Unloadables". When possible, Raylib Go Plus will have a record to every object that is loaded via LoadXXXX pattern, and will delete their record when Unload() is called on them. This is a useful safety feature to just make sure everything is unloaded.

Because they are tracked, you can call r.UnloadAll() at the end of your application to free up all recorded Unloadables from the C memory, preventing memory leaks.

Please note that this is an experimental feature, and not all Loadables maybe added to the tracker, nor may they all be added for every Load functions (ie: some GetXXXX may require unloading too). It is recommended to always free up the object yourself using Unload()

Anything that is loaded using a LoadXXXX should be in OOP mode of the converter. The converter will add Unload methods. In cases where they are named Close instead (ie AudioStream), please make the OOP method Unload, and the functional method the original Close.

RayGUI & RayMath

Both raygui and raymath are implemented by default in the raylib package. The reasoning behind not seperating raygui was because of a technical limitation with cgo (the interface used to link the c files into go) not being able to support links outside the package directory (I would have to include the entire raylib.h again into a raygui package).

License

This project is still a work in progress, but the license will be zlib/libpng to keep it inline with Raylib license.

raylib-goplus's Issues

LoadMusicStream Hard Crash

Issue
LoadMusicStream will hard crash if the InitAudioDevice has not yet been called.

Expected Result
LoadMusicStream should throw an error

Proposal
LoadMusicStream should return Music and Error to follow Go Paradigms, throwing if audio is not yet initialized.

[QoL] RayPhsics

The Current Issue
There is currently no raylib physics implementation

The Proposal
Proposed to add Raylibs implementation of Physics.
https://github.com/raysan5/raylib/blob/master/src/physac.h

How do I load the default internal shader from LoadShaderCode?

When using LoadShader, if you put a blank string in the filename, it loads the default vertex shader. But in LoadShaderCode, putting a blank string as input causes the error

INFO: ERROR: Compiled vertex shader was corrupt.

How do I load the default vertex shader using LoadShaderCode?

[BUG] Program failing to load due to Shader

Describe the bug
My game in raylib-goplus will compile successfully, the window will pop up, then immediately close. I've entered the debugger to follow the stack trace down, since all that is returned is an error code.

Process finished with exit code -1073741819 (0xC0000005)

I've been able to isolate this down to the drawing of a cube with a Shader attached. It's not a complex shader by any means, and it can be noted that it does compile just fine as per the raylib trace logs.

Upon further inspection, it's possibly related to the way in which goplus has it's Model structured. *[]Meshes Is a field that may cause runtime panics as the reference could be nil. Possible solution to this, would be to follow the style gen2brains uses by using a standard []Meshes slice. Even with a simple generated cube from raylib's own r.GenMeshCube(1.0,1.0,1.0) shows the *[]Meshes slice to have a length and capacity of:

To Reproduce
Steps to reproduce the behavior:
Example Shader VS
Example Shader FS

Generate a cube mesh, load a model from that, add these shaders. An example in C can be found here

Expected behavior
Upon opening the program, it shouldn't fail, and the skybox shader should be rendered on screen. (Sorry not sure what else to put here ^^)

[QoL] Loading a Shader returns a pointer

The Current Issue
When loading a new shader, it returns a pointer to the Shader rather than the Shader struct itself. While this isn't a huge inconvenience, it does require immediate de referencing.

tile.Materials[0].Shader = *r.LoadShader("resources/shaders/simpleLight.vs", "resources/shaders/simpleLight.fs")

This functionality could be changed into two possible ways.. One, we could have it return the struct instead of a pointer.. Secondly it could return both an err and the shader.

The Paradigm to Match

myShader, err := r.LoadShader("...", "...")
if err != nil {
//do stuff
}

tile.Materials[0].Shader = *myShader

tile.Materials[0].Shader = r.LoadShader("resources/shaders/simpleLight.vs", "resources/shaders/simpleLight.fs")

The Proposal
The first option would follow a more go style of coding, with the error handling being checked right after loading. The second would have the error handling follow more the C style, and just keep trucking along.

[QoL] LoadXXX should return errors

The Current Issue
LoadSound will just silently fail and won't work silently when trying to use it.

The Paradigm to Match
When loading sounds, an error should be returned to validate that it loaded correctly.

The Proposal
Error response will have to be a case-by-case improvement. LoadSound will have a different way to check nil than LoadFont for example.

//LoadSound : Load sound from file
func LoadSound(fileName string) (*Sound, error) {
	cfileName := C.CString(fileName)
	defer C.free(unsafe.Pointer(cfileName))
	res := C.LoadSound(cfileName)
	if res.stream.buffer == nil {
		return nil, errors.New("Failed to load sound file")
	} 

	retval := newSoundFromPointer(unsafe.Pointer(&res))
	addUnloadable(retval)
	return retval, nil
}

Keyboard (azerty, qwerty)

Hi!

I would like to point out that the Keyboard only takes into account the qwerty, on my azerty keyboard the Z key is not recognized as Z but as W

SetValueTexture not working

Describe the bug
The GLSL shader is only receiving a 1x1 black texture, instead of the proper texture. I have tried saving this texture to a PNG, rendering this texture to the screen, and it all worked. Yet, in the shader, it is only receiving a 1x1 black texture.

This texture is being used in a shader I got by doing r.LoadShaderCode. Here is a code snippet of how it is set up:

shader = r.LoadShaderCode(defaultVs, blurFs)
shader.SetValueTexture(shader.GetLocation("colMap"), colorMap)

Inside of the shader I have:

uniform sampler2D colMap;

and in the code I have:

finalColor = texture(colMap, vec2(0, 0));

I have also tried using glsl's textureSize:
Dividing the texture size by 1 gives white. (code below)

finalColor = vec4(vec3(textureSize(colMap, 0).x)/1, 1);

Dividing the texture size by 2 gives a gray-ish color (code below)

finalColor = vec4(vec3(textureSize(colMap, 0).x)/2, 1);

The dimensions of this texture are 3x1 and the dimensions of texure0 are 800x450. Can this cause a problem?

Edit:
I tried resizing the image to be the size of texture0, still didn't work.

[BUG] LoadFontEx doesn't take pointer to ints

Hello!

Describe the bug
LoadFontEx() should be able to take a pointer to an array of ints for the fontChars argument; instead it just accepts a single integer. This prevents you from specifying a range of characters to load when loading the font, I believe. See the cheatsheet.

[QoL] text functions should support Sprint

The Current Issue
DrawText currently takes a string and draws a text to the screen

The Paradigm to Match
The text argument is flat and must require a manual call to Sprint for formatting. A better solution would to incorporate this.

The Proposal
The proposal is for all text functions to have a second version created that accepts an ...interface{} like Sprint. In the provided example, DrawText will now get a sibling: DrawFormattedText.

The prefix is a WIP. Here are some suggestions:
DrawFormattedText
DrawStext
DrawTextf
DrawTextFormatted
DrawSprint
SDrawText

Feedback is welcomed

Can you make a Raylib Image into a Go Image?

You can make a Go image into a Raylib image, but is there any way to go back?

[QoL] Material level access to texture function

The Current Issue
When wanting to set a filter for a texture inside of a material, the current process looks like:

tile.Materials[0].Maps[r.MapAlbedo].Texture.SetTextureFilter(r.FilterAnisotropic16x)

The Proposal
It would be nice to have the ability to access this function (and perhaps those like it) by simply calling on the Material as you would SetTexture

tile.Materials[0].SetTextureFilter(r.MapAlbedo, r.FilterAnisotropic16x)

[BUG] Trace Logs end prematurely

Describe the bug
The output trace logs end prematurely, with information no longer being displayed.

INFO: [resources/textures/inventorybg.png] Image loaded successfully (1920x1080)
INFO: [TEX ID 9] Texture created successfully (1920x1080 - 1 mipmaps)
INFO: [TEX ID 2] Unloaded texture data from VRAM (GPU)
INFO: [TEX ID 1] Unloaded textur
Process finished with exit code -1073740940 (0xC0000374)

Before ending the program, the output log had just stopped mid line and didn't continue on. (Should display the rest of the loading? And then also display the teardown/unloadables)

When the program is exited the error above can be seen

Process finished with exit code -1073740940 (0xC0000374)

To Reproduce
Load a few textures, models, and watch the log stop logging.

Expected behavior
The log should behavior as it would in C, by continuing to log each piece of trace log.

Not Really a BUG but missing some features [BUG]

Just to say I use your port of Raylib for Go just about everyday and it is great. Basically however some features seem to be missing which would be good to be able to use. The 3 below are ones that I am missing though I am sure there are more. I do understand you might be busy and it might be difficult to add though if you can put on a TO DO list you may have it would be great to have implemented in future. (these are from https://www.raylib.com/cheatsheet/cheatsheet.html)

DrawTexturePoly(Texture2D texture, Vector2 center, Vector2 *points, Vector2 *texcoords, int pointsCount, Color tint); // Draw a textured polygon

DrawPolyLines(Vector2 center, int sides, float radius, float rotation, Color color); // Draw a polygon outline of n sides

GetCharPressed(void); // Get char pressed (unicode), call it multiple times for chars queued

To Reproduce
Try and use the functions DrawTexturePoly or DrawPolyLines or GetCharPressed

Expected behavior
Something however nothing is possible without the functions :(

Issue Getting Custom Colors to Work

Not sure if this is a bug or I am not doing it correctly however apart from the predefined colors raylib also seems to offer the ability to define your own colors using RGBA values.

I am however really struggling to get this to work. If you take a look at the images or text below.

I create the color using the code

// colors green2 = rl.Color{77, 255, 77, 1}

which seems to work fine however Visual Studio Code gives me a WARNING (not error)

github.com/lachee/raylib-goplus/raylib.Color composite literal uses unkeyed fields

However it allows me to compile the code the problem is that though the program runs the color is blank and does not display, what is supposed to be green is just blank with no color at all.

If you have any help/advice as to how to create/use custom colors it would be really appreciated.

[QoL] Define a .mod file for raylib-goplus

The Current Issue
Hello!

Thanks for your work on raylib-goplus; it's definitely a huge step in the right direction to automatically generate new bindings for raylib for Go.

When it comes to actually using raylib-goplus, I believe it would be more idiomatic to use Go Modules to allow projects that use this library to download and import it without having to manually run go get, and to make the status of projects that use it reproducible (because it refers to a specific version of a library that is known to work with the project).

The Paradigm to Match
Instead of running go get on a library (raylib-goplus, in this case), just importing it should have Go automatically download and include it in the project's go.mod file, due to the library having the go.mod file included.

The Proposal
To fix this, simply initialize a new module with the project's name / URL using go mod init and commit it to the root of the module. This will allow recent Go versions to automatically retrieve it from the URL specified, download it, and import it without issue.

[QoL] GetLocation should return an int32

The Current Issue
GetLocation when called on a Shader returns an int. However the Shader location array accepts only int32.

tile.Materials[0].Shader.Locs[r.LocMatrixModel] = int32(tile.Materials[0].Shader.GetLocation("matModel"))

The Proposal

tile.Materials[0].Shader.Locs[r.LocMatrixModel] = tile.Materials[0].Shader.GetLocation("matModel")
