# Pixel [](https://godoc.org/github.com/faiface/pixel) [](https://goreportcard.com/report/github.com/faiface/pixel)
|
|
|
|
A simple, easy to use, fast, flexible, hand-crafted 2D game library in Go.
|
|
|
|
```
|
|
go get github.com/faiface/pixel
|
|
```

## Tutorial
|
|
|
|
The [Wiki of this repo](https://github.com/faiface/pixel/wiki) contains an extensive tutorial
|
|
covering several topics of Pixel. Here's the content of the tutorial parts so far:
|
|
|
|
- [Creating a Window](https://github.com/faiface/pixel/wiki/Creating-a-Window)
|
|
- [Drawing a Sprite](https://github.com/faiface/pixel/wiki/Drawing-a-Sprite)
|
|
- [Moving, scaling and rotating with Matrix](https://github.com/faiface/pixel/wiki/Moving,-scaling-and-rotating-with-Matrix)
|
|
- [Pressing keys and clicking mouse](https://github.com/faiface/pixel/wiki/Pressing-keys-and-clicking-mouse)
|
|
- [Drawing efficiently with Batch](https://github.com/faiface/pixel/wiki/Drawing-efficiently-with-Batch)
|
|
- [Drawing shapes with IMDraw](https://github.com/faiface/pixel/wiki/Drawing-shapes-with-IMDraw)
|
|
|
|
## Examples
|
|
|
|
The [examples](https://github.com/faiface/pixel/tree/master/examples) directory contains a few
|
|
examples demonstrating Pixel's functionality.
|
|
|
|
**To run an example**, navigate to it's directory, then `go run` the `main.go` file. For example:
|
|
|
|
```
|
|
$ cd examples/platformer
|
|
$ go run main.go
|
|
```
|
|
|
|
Here are some eye-catching screenshots from the examples!

## Features
|
|
|
|
Here's the list of the main features in Pixel. Although Pixel is still in heavy development, **you
|
|
can quite expect that the features and API that is inside the library now, will not change in major
|
|
ways.** This is not a 100% guarantee thought.
|
|
|
|
- Fast 2D graphics
|
|
- Sprites
|
|
- Primitive shapes with immediate mode style
|
|
[IMDraw](https://github.com/faiface/pixel/wiki/Drawing-shapes-with-IMDraw) (circles, rectangles,
|
|
lines, ...)
|
|
- Optimized drawing with [Batch](https://github.com/faiface/pixel/wiki/Drawing-efficiently-with-Batch)
|
|
- Simple and convenient API
|
|
- Drawing a sprite to a window is as simple as `sprite.Draw(window)`
|
|
- Adding and subtracting vectors with `+` and `-` operators... how?
|
|
- Wanna know where the center of a window is? `window.Bounds().Center()`
|
|
- [...](https://godoc.org/github.com/faiface/pixel)
|
|
- Full documentation and tutorial
|
|
- Works on Linux, macOS and Windows
|
|
- Window creation and manipulation (resizing, fullscreen, multiple windows, ...)
|
|
- Keyboard and mouse input without events
|
|
- Well integrated with the Go standard library
|
|
- Use `"image"` package for loading pictures
|
|
- Use `"time"` package for measuring delta time and FPS
|
|
- Use `"image/color"` for colors, or use Pixel's own `color.Color` format, which supports easy
|
|
multiplication and a few mor features
|
|
- Pixel uses `float64` throughout the library, compatible with `"math"` package
|
|
- Geometry transformations with
|
|
[Matrix](https://github.com/faiface/pixel/wiki/Moving,-scaling-and-rotating-with-Matrix)
|
|
- Moving, scaling, rotating
|
|
- Easy camera implementation
|
|
- Off-screen drawing to Canvas or any other target (Batch, IMDraw, ...)
|
|
- Fully garbage collected, no `Close` or `Dispose` methods
|
|
- Full [Porter-Duff](http://ssp.impulsetrain.com/porterduff.html) composition, which enables
|
|
- 2D lighting
|
|
- Cutting holes into objects
|
|
- Much more...
|
|
- Pixel let's you draw stuff and do your job, it doesn't impose any particular style or paradigm
|
|
- Platform and backend independent [core](https://godoc.org/github.com/faiface/pixel)
|
|
- Core Target/Triangles/Picture pattern makes it easy to create new drawing targets that do
|
|
arbitrarily crazy stuff (e.g. graphical effects)
|
|
- Small codebase, ~5K lines of code, together with the backend
|
|
[glhf](https://github.com/faiface/glhf) package
|
|
|
|
## Missing features
|
|
|
|
Pixel is in development and still missing few critical features. Here're the most critical ones.
|
|
|
|
- Audio
|
|
- Drawing text
|
|
- Antialiasing (filtering is supported, though)
|
|
- Better support for Hi-DPI displays
|
|
- More advanced graphical effects (e.g. blur)
|
|
|
|
**Implementing these features will get us to the 1.0 release.** Contribute, so that it's as soon as
|
|
possible!
|
|
|
|
## Requirements
|
|
|
|
[PixelGL](https://godoc.org/github.com/faiface/pixel/pixelgl) backend uses OpenGL to render
|
|
graphics. Because of that, OpenGL development libraries are needed for compilation. The dependencies
|
|
are same as for [GLFW](https://github.com/go-gl/glfw).
|
|
|
|
- On macOS, you need Xcode or Command Line Tools for Xcode (`xcode-select --install`) for required
|
|
headers and libraries.
|
|
- On Ubuntu/Debian-like Linux distributions, you need `libgl1-mesa-dev` and `xorg-dev` packages.
|
|
- On CentOS/Fedora-like Linux distributions, you need `libX11-devel libXcursor-devel libXrandr-devel
|
|
libXinerama-devel mesa-libGL-devel libXi-devel` packages.
|
|
- See [here](http://www.glfw.org/docs/latest/compile.html#compile_deps) for full details.
