go-raylib's Issues

Latest commit won't compile on Linux

When trying to compile basic_window.go on Linux, using the latest commit 6ee277f, I get this error output:

/usr/bin/ld: ../../../../pkg/mod/github.com/chunqian/[email protected]/raylib/../lib/raylib/plat/linux/libraylib.a(text.c.o): relocation R_X86_64_32S against `.rodata' can not be used when making a PIE object; recompile with -fPIE

No binary is built.

This is the default gcc flags Go is using. I never set this myself.

➤ go env GOGCCFLAGS
-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build988534947=/tmp/go-build -gno-record-gcc-switches

I had trouble changing it to use -fPIE instead and gave up.

The latest commit that successfully compiles on Linux is 90039da , before any .a files have been added. There were some warnings, but a binary was made and it worked fine.

My suggestion: Just remove the .a files. What is the point of having them? I'd rather just build the library myself.

Why update raylib?

Why did you update the raylib library in c620d8c? Shouldn't this code stick to the 3.5 release? 3.6-dev will update frequently and have bugs, it's not ready yet.

Trouble installing package

So I'm trying to import it but with no success:

the go.mod:

if I run go mod tidy:

go: finding module for package github.com/chunqian/go-raylib
github.com/jeedee/kobu-server imports
        github.com/chunqian/go-raylib: module github.com/chunqian/go-raylib@latest found (v0.0.0-20210519095144-df36dae46c76), but does not contain package github.com/chunqian/go-raylib

Different result in go and C function: LoadFontEx

Hi I'm struggling with text output and almost gave up.

And As I see main problem is function : LoadFontEx

It works in C, I took an example about text and have such string :
Font fontTtf = LoadFontEx("Ubuntu-Regular.ttf", 256, 0, 2048);
in the log output:


INFO: FILEIO: [Ubuntu-Regular.ttf] File loaded successfully
INFO: TEXTURE: [ID 3] Texture created successfully (16384x16384 - 1 mipmaps)

in Go I have such string:
font := rl.LoadFontEx("Ubuntu-Regular.ttf", 256, &s, 2048)
and in the logs :

INFO: FILEIO: [Ubuntu-Regular.ttf] File loaded successfully
INFO: TEXTURE: [ID 3] Texture created successfully (512x512 - 1 mipmaps)

and of course there is no any output in the window of go version.
And all works perfect with C version.

I'm writing here because I see project looks alive and maybe some one has solution.

OS:
MacOS 11
arm64

Go:
1.16.3

go-raylib:
v0.0.0-20210424023010-5a21bdadf8d6

Hey, this is my first issue on Github, so bear with me...
I've been playing around with Raylib using pure interop with Swift language. As a comparison, I wanted to check for memory leaks against Go (which is a language I'm familiar with), and I found something interesting.

No matter what code it would be, you could use an example provided, and you would get similar or the same memory loss/leak.
I will go straight to the point.

Memory Check with Valgrind
If you check out the gist linked above, you can see that around 40,015 bytes in 573 blocks are possibly lost in go-raylib binding vs 0 bytes in 0 blocks against Swift's pure interop to C without any safe pointer management etc.

I did post this on raylib discord server under Go's channel, but I take it you aren't on the server? So I didn't know if it was worth posting it here either or not and find out what exactly is going on. Is it the binding that is leaking memory or something else?

Thanks!

Custom raylib build

Is there a way to use custom build of raylib. Or much better surround definitions in config.h file with ifndef flags and we can define custom options from CGO_CFLAGS

Running `go build` throws error

Note: I'm using go mod vendor which brings files to workspace folder:

edit: I was messing with the local files, seems to be a problem with cgo package?

Also according to the error message on the build process the file rglfw.c wasnt found, but I could find it here, just dont know how go does to find it:

IMPORTANT: This also happens on Linux (even after installing those packages: apt-get install libgl1-mesa-dev libxi-dev libxcursor-dev libxrandr-dev libxinerama-dev )

Visual glitch until moving window MacOS

Hi not sure if this come from Raylib itself or the bindings, but I got a weird glitch on my Mac. I just want to draw a rectangle, and it is drawn very small until I move the window, see the video:

raylib-weird.mp4

The code itself is really simple:

package main

import (
	rl "github.com/chunqian/go-raylib/raylib"
	"runtime"
)

const screenWidth = 1280
const screenHeight = 720

type Game struct {
	player *Player
}

func NewGame() Game {
	player := Player{
		pos:      rl.Vector2{20, 20},
		velocity: rl.Vector2{0, 0},
		size:     rl.Vector2{32, 64},
	}
	g := Game{player: &player}

	return g
}

type Player struct {
	pos, velocity, size rl.Vector2
}

func (g Game) Run() {
	rl.InitWindow(screenWidth, screenHeight, "raylib [core] example - basic window")
	defer rl.CloseWindow()

	rl.SetTargetFPS(60)

	for !rl.WindowShouldClose() {
		g.Update()
		g.Draw()
	}
}

func (g Game) Update() {

}

func (g Game) Draw() {
	rl.BeginDrawing()
	defer rl.EndDrawing()

	rl.ClearBackground(rl.RayWhite)
	rl.DrawRectangleV(g.player.pos, g.player.size, rl.Green)
}

func init() {
	runtime.LockOSThread()
}

func main() {
	g := NewGame()
	g.Run()
}

Anyway, thanks for your work on this binding !

I think you did a mistake in your go.mod, i can't get go-raylib

Update to raylib 3.7

raylib 3.7 was just released. No rush on the update, just wanted to make this issue just in case.

Thanks for all your work maintaining this library! 😄

macOS warning - Implicit conversion of int to float

Hi,

Recently found this warning popping up regarding implicit conversion of int to float from within go-raylib:

Error running gui examples on Windows 10

OS: Windows 10

Im try to test gui examples, but throws

C:/Users/usour/go/pkg/mod/github.com/chunqian/[email protected]/lib/raygui/src/raygui.h:3196: multiple definition of `GuiCheckIconPixel'
C:\Users\usour\AppData\Local\Temp\go-build1291992362\b038_x002.o:C:/Users/usour/go/pkg/mod/github.com/chunqian/[email protected]/lib/raygui/src/raygui.h:3196: first defined here

I recompiled raylib including physac and raygui , but throws the same error.

What could be ?

PBR example doesn't work on Linux [upstream]

Most examples are working great on Linux, I'm happy to see it! cubicmap and first_person_maze, for example. But the PBR one is not.

Key line is:

WARNING: MATERIAL: [../models/resources/pbr/trooper.obj] Failed to load material data, default to white material

All other files are loaded successfully, I'm not sure why this one failed.

Build command is from the README.

How do I use this as a dependency?

With raylib-go I can just import the package into my project and Go will automatically compile raylib as needed. The README for this library shows manual compilation, and only demonstrates using the library for single-file examples in the same project. How can I import this and use it in a separate project?

Thank you!

Can you add linux support ?

Hello,

Thank you for your great work.
Can you add linux support please ?

Convert `const unsigned char` to `[]byte`, not `string`

Looking at the raylib cheatsheet, you can see that in many places const char is used for strings, while const unsigned char is used for bytes. But this package converts both of those to Go's string type. This is a problem, because if I load some bytes from a file or memory (maybe to load an image), I need to convert those bytes first with string(bytes). This copies all of the bytes before giving them to the library, because strings are immutable. Copying the bytes is an expensive and useless operation here.

There are ways around the copying, but could you just change the binding, so it converts const unsigned char to []byte? Thanks!

Example function that does this:

Image LoadImageFromMemory(const char *fileType, const unsigned char *fileData, int dataSize);
