Golang New Examples

Example #1

File: bomberman.go Project: nkts/golang-devops-stuff

func (b *Bomberman) manageBombs() {
	timeBombs := map[string]*timebomb.TimeBomb{}

	for {
		select {
		case container := <-b.strap:
			if container.GraceTime() == 0 {
				continue
			}

			bomb := timebomb.New(
				container.GraceTime(),
				func() {
					b.detonate(container)
					b.defuse <- container.Handle()
				},
			)

			timeBombs[container.Handle()] = bomb

			bomb.Strap()

		case handle := <-b.pause:
			bomb, found := timeBombs[handle]
			if !found {
				continue
			}

			bomb.Pause()

		case handle := <-b.unpause:
			bomb, found := timeBombs[handle]
			if !found {
				continue
			}

			bomb.Unpause()

		case handle := <-b.defuse:
			bomb, found := timeBombs[handle]
			if !found {

			}

			bomb.Defuse()

			delete(timeBombs, handle)
