Go Pixel Snake

Go Pixel Snake is a weekend project to create a Snake game in Go, using the Pixel game library.

Install

Build from source

The Pixel game engine uses an Opengl back-end which requires platform specific dependencies for compilation. You will have to install these dependencies on your system first.

Go Pixel Snake uses the go dep tool to manage its own dependencies.

go get github.com/golang/dep
go get github.com/benjmarshall/gopixelsnake
cd $GOPATH/src/github.com/benjmarshall/gopixelsnake
dep ensure
go install

Pre-built

Alternatively download one of the pre-built binaries from the releases page.

Bugs

There are probably many bugs in here. If you spot something major please submit an issue.

tickerMultiplex causes 100% CPU usage

Hi! Cool game and thanks for using my lib ;)

However, your game consumer much more CPU than required and the reason is the tickerMultiplex function:

func tickerMultiplex(out chan<- time.Time, tickerIn <-chan time.Time, startIn <-chan time.Time) {
	for true {
		select {
		case t := <-tickerIn:
			out <- t
		case t, ok := <-startIn:
			if !ok {
				return
			}
			out <- t
		default:
		}
	}
}

Due to the default: branch, this for loop spins furiously. Removing the default branch fixes the problem (the select will wait for either of the channels in such case, consuming no CPU).
