go-game

Now working with ebiten v2!

See go-game-old for the previous version.

Install dependancies

Install those:

• Golang
• Git
• GitHub Desktop

Run in a terminal:

go get github.com/hajimehoshi/ebiten
go get -u github.com/dave/wasmgo
##(not useful/working?) go get -u github.com/gopherjs/gopherwasm

You may also need those dependancies on Linux:

# on redhat-like distrib (e.g. Fedora)
sudo dnf install libXcursor-devel libXinerama-devel libXi-devel
# on debian-like (NOT TESTED)
sudo apt-get install libXcursor-dev libXinerama-dev libXi-dev

go get github.com/golang/freetype/truetype
go get golang.org/x/image/font

Run as an application

Debug

# install the debugger
go get -u github.com/go-delve/delve/cmd/dlv # if you want the dlv debugger
go build github.com/go-delve/delve/cmd/dlv # and put ./dlv into your $PATH

cd ./src/ludumdare44
dlv debug

(dlv) continue
(dlv) quit

Or press F5 while in Atom on the main.go file tab, and select config "Debug" (AFAIK, must have been run in the console once before that.)

Build on Windows

# version depending of the data/ directory
cd src\ludumdare44 && go build -tags USE_WINSYSTEMMETRICS && ludumdare44.exe

# self-contained version
go build -o ./release/ludumdare44.exe -tags "USE_SELFCONTAINED_MODE USE_WINSYSTEMMETRICS" ./src/ludumdare44 && .\release\ludumdare44.exe

Build on Linux

# version depending of the data/ directory
cd ./src/ludumdare44 && go build && ./ludumdare44

# self-contained version
go build -o ./release/ludumdare44 -tags USE_SELFCONTAINED_MODE ./src/ludumdare44 && ./release/ludumdare44

Build as a web page

More info

Build as a web page (new)

# on linux:
GOOS=js GOARCH=wasm go build -tags USE_SELFCONTAINED_MODE -o ./web_release/test.wasm ./src/ludumdare44
firefox web_release

# on windows:
set GOOS=js
set GOARCH=wasm
go build -tags USE_SELFCONTAINED_MODE -o ./web_release/test.wasm ./src/ludumdare44

• To make it work on recent versions of Firefox (at least on local tests), you need to access about:config in the URL and set privacy.file_unique_origin to false. (Reset it to true when you have finished testing.)
• Click on wasm_exec.html
• Click on Play!
• Wait a minute

Build as a web page (old - not working)

cd ./src/ludumdare44
go build github.com/dave/wasmgo
wasmgo serve -f "-tags USE_SELFCONTAINED_MODE"
# While it is running, open Firefox to the url: http://localhost:8080/

Or Build as a web page, directly with editable code: (Warning: Not working, play.jsgo.io services have been shut down, so it does not work any more.) First commit on a public repository (e.g. https://github.com/phrounz/go-game ) and then: Play - Compile - Run

To make generate_data_go.pl work (to regenerate pictures for self-contained mode)

On Windows

• Install Strawberry Perl
• Install ImageMagick
• hack $IMAGEMAGICK_CMD_LINE_UTILITY in the source code

cd ./src/ludumdare44
go get https://github.com/hajimehoshi/file2byteslice
go build https://github.com/hajimehoshi/file2byteslice
perl generate_data_go.pl

On Linux

• Perl should already be installed
• Install ImageMagick

# on redhat-like distrib (e.g. Fedora)
dnf install ImageMagick

• hack $IMAGEMAGICK_CMD_LINE_UTILITY in the source code, replace by 'magick'
• get file2byteslice

cd ./src/ludumdare44
go get https://github.com/hajimehoshi/file2byteslice
go build https://github.com/hajimehoshi/file2byteslice
perl generate_data_go.pl

Install a full Atom environment to develop:

Install Atom.

Install Atom packages with Ctrl+, -> Install:

go-plus
minimap

Reminder: on Atom, Ctrl+Shift+M show preview for .md files like this one.
