		return e.Get(TYPE.Box).(Box)
	},

	SolidBox: func(e *goecs.Entity) SolidBox {

Get a geometry component

var TYPE = types{
	Box:      goecs.NewComponentType(),
	SolidBox: goecs.NewComponentType(),
	Line:     goecs.NewComponentType(),
}

TYPE hold the goecs.ComponentType for our shapes components

Types

type Box

type Box struct {
	Size      geometry.Size // The box size
	Scale     float32       // The box scale
	Thickness int32         // Thickness of the line
}

Box is a rectangular outline that we could draw in a geometry.Point with a color.Solid

func (Box) Contains

func (b Box) Contains(at geometry.Point, point geometry.Point) bool

Contains return if a box at a geometry.Point contains a point

func (Box) GetReactAt

func (b Box) GetReactAt(at geometry.Point) geometry.Rect

GetReactAt return return a geometry.Rect at a given point

func (Box) Type

func (b Box) Type() goecs.ComponentType

Type return this goecs.ComponentType

type Line

type Line struct {
	To        geometry.Point // To where the line goes
	Thickness float32        // Thickness of the line
}

Line is a component that represent a line

func (Line) Type

func (l Line) Type() goecs.ComponentType

Type return this goecs.ComponentType

type SolidBox

type SolidBox struct {
	Size  geometry.Size // The box size
	Scale float32       // The box scale
}

SolidBox is a rectangular shape that we could draw in a geometry.Point with a color.Solid or color.Gradient

func (SolidBox) Contains

func (b SolidBox) Contains(at geometry.Point, point geometry.Point) bool

Contains return if a box at a geometry.Point contains a point

func (SolidBox) Type

func (b SolidBox) Type() goecs.ComponentType

Type return this goecs.ComponentType
