Install
Caution: Ebitengine on FreeBSD is not tested well by the author.
Desktop Environment
Ebitengine requires X Window system and you need to install a window manager like GNOME3. See the official manual. Note that you also need to do pkg install xorg
.
Installing Go
Install Go on your machine. Ebitengine requires Go 1.15 or later.
Note that you do NOT need a C compiler for Ebitengine on Windows.
Installing a C compiler
A C compiler is required as Ebitengine uses not only Go but also C.
On the latest macOS, just type clang
on your terminal and a dialog would appear if you don't have clang compiler. Follow the instruction to install it.
You might find the following error when executing clang.
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
In this case, run xcode-select --install
and install commandline tools.
Use your distribution's package manager. For example, Ubuntu can use apt
.
apt install gcc
Use pkg
.
pkg install clang
Installing dependencies
Debian / Ubuntu
sudo apt install libc6-dev libglu1-mesa-dev libgl1-mesa-dev libxcursor-dev libxi-dev libxinerama-dev libxrandr-dev libxxf86vm-dev libasound2-dev pkg-config
Fedora
sudo dnf install mesa-libGLU-devel mesa-libGLES-devel libXrandr-devel libXcursor-devel libXinerama-devel libXi-devel libXxf86vm-devel alsa-lib-devel pkg-config
Solus
sudo eopkg install libglu-devel libx11-devel libxrandr-devel libxinerama-devel libxcursor-devel libxi-devel libxxf86vm-devel alsa-lib-devel pkg-config
Arch
sudo pacman -S mesa libxrandr libxcursor libxinerama libxi pkg-config
Alpine
sudo apk add alsa-lib-dev libx11-dev libxrandr-dev libxcursor-dev libxinerama-dev libxi-dev mesa-dev pkgconf
pkg install alsa-lib libxcursor libxi libxinerama libxrandr mesa-libs pkgconf
Confirming your environment
You can check whether you have a correct environment by executing an example:
go run -tags=example github.com/hajimehoshi/ebiten/v2/examples/rotate@latest
Note that -tags=example
is needed to execute the examples as the Ebitengine example packages require the build tag.
If you see this window with a rotating Gophers image, congratulations! You have a correct environment to use Ebitengine!
Running a program with Ebitengine
Ebitengine can be used as a usual Go library. Go command automatically installs Ebitengine when your program uses Ebitengine.
First, create your local module.
# Create a directory for your game.
mkdir yourgame
cd yourgame
# Initialize go.mod by `go mod init`.
go mod init github.com/yourname/yourgame
Use URL for your module name like github.com/yourname/yourgame
. Actually, any module name like example.com/m
is fine as long as you don't plan to share this publicly. You can change the module name anytime later.
Add main.go
with this content:
Run go mod tidy
to add dependencies to your go.mod
:
go mod tidy
Finally, run go run
to execute your program.
go run .
You will be able to see a window with a message:
