Functions

func DrawNumber

func DrawNumber(bg *ebiten.Image, x, y, width float64, n int)

func Intersect

func Intersect(s *Sphere, e *Explosion) bool

Return true if a speger and explosion touch

Types

type Explosion

type Explosion struct {
	// contains filtered or unexported fields
}

Increase an explosion

type Sphere

type Sphere struct {
	// contains filtered or unexported fields
}

Basic game object, will essentially render as just a circle

func NewSphere

func NewSphere(w, h float64) *Sphere

Create a new sphere, in a random place, with random colours and a random direction of movement.

func TestSphere

func TestSphere(w, h float64, ix int) *Sphere

Create a test sphere

func (*Sphere) Draw

func (s *Sphere) Draw(t *ebiten.Image)

Render a sphere onto the game display

func (*Sphere) Explode

func (s *Sphere) Explode() *Explosion

Turn a sphere into an explosion.

func (*Sphere) Step

func (s *Sphere) Step(w, h float64)

Advance a sphere one step, bouncing against the borders if necessary.
