    DoUncover string = "uncover"
)

type API ¶

API is an interface for APIs communicating with the backend.

type API interface {
    HostAPI()
}

func NewGraphQlAPI ¶

func NewGraphQlAPI(field *Playground) (API, error)

NewGraphQlAPI creates a new GraphQLAPI

type Guess ¶

Guess represents the probability that a cell contains a bomb. The Probability should have a value between 0.0 and 1.0.

type Guess struct {
    X           int
    Y           int
    Probability float32

    Action string
}

type Playground ¶

Playground contains the a slice of rows of the field.

type Playground struct {
    Rows []Row
    Win  bool
    // contains filtered or unexported fields
}

p := NewPlayground()
_ = p.Init(5, 5, 0)
p.placeBomb(3, 3)
p.placeBomb(4, 3)
p.placeBomb(3, 4)
p.Uncover(0, 0)
p.flagsLeft++
p.ToggleFlag(4, 4)
fmt.Println(p.ToString())

func NewPlayground ¶

func NewPlayground() *Playground

NewPlayground generates a new Playground

func (*Playground) InRange ¶

func (field *Playground) InRange(x, y int) bool

InRange checks whether the given coordinates are inside the playground. If the position is inside the playground true is returned, otherwise false.

func (*Playground) Init ¶

func (field *Playground) Init(sizeX, sizeY, bombs int) error

Init a new playground with the given size. The size of the playground gets passed to the method.

func (*Playground) ToString ¶

func (field *Playground) ToString() string

ToString generates a string representation of the playground.

func (*Playground) ToggleFlag ¶

func (field *Playground) ToggleFlag(x, y int)

ToggleFlag either sets or unsets a flag.

func (*Playground) Uncover ¶

func (field *Playground) Uncover(x, y int)

Uncover uncovers the field at the given position and sets the CloseBombs variable so it gets visible in the UI

type Position ¶

Position contains all required information about the representing position on the playground.

type Position struct {
    Uncovered         bool
    BombBackend       bool
    Bomb              bool
    Flagged           bool
    CloseBombsBackend int
    CloseBombs        int
    // contains filtered or unexported fields
}

type Row ¶

Row contains a slice of positions.

type Row struct {
    Fields []Position
}
