Functions

func Distance

func Distance(x, y *Vec3) float64

func MNaN32

func MNaN32() float32

Types

type Transform

type Transform struct {
	Position Vec3 `db:"position" json:"position"`
	Rotation Vec3 `db:"rotation" json:"rotation"`
	Scale    Vec3 `db:"scale" json:"scale"`
}

Transform represent a transformation for an object in 3D space.

func (Transform) MarshalMUS

func (v Transform) MarshalMUS(buf []byte) int

MarshalMUS fills buf with the MUS encoding of v.

func (Transform) SizeMUS

func (v Transform) SizeMUS() int

SizeMUS returns the size of the MUS-encoded v.

func (*Transform) UnmarshalMUS

func (v *Transform) UnmarshalMUS(buf []byte) (int, error)

UnmarshalMUS parses the MUS-encoded buf, and sets the result to *v.

type TransformNoScale

type TransformNoScale struct {
	Position Vec3 `db:"position" json:"position"`
	Rotation Vec3 `db:"rotation" json:"rotation"`
}

TransformNoScale represents a transformation for an object in 3D space that has no scale. For example, users don't have a scale in the current system.

func (*TransformNoScale) Copy

func (t *TransformNoScale) Copy() TransformNoScale

func (*TransformNoScale) CopyToBuffer

func (t *TransformNoScale) CopyToBuffer(b []byte) error

func (TransformNoScale) MarshalMUS

func (v TransformNoScale) MarshalMUS(buf []byte) int

MarshalMUS fills buf with the MUS encoding of v.

func (TransformNoScale) SizeMUS

func (v TransformNoScale) SizeMUS() int

SizeMUS returns the size of the MUS-encoded v.

func (*TransformNoScale) UnmarshalMUS

func (v *TransformNoScale) UnmarshalMUS(buf []byte) (int, error)

UnmarshalMUS parses the MUS-encoded buf, and sets the result to *v.

type Vec3

type Vec3 struct {
	X float32 `json:"x" db:"x"`
	Y float32 `json:"y" db:"y"`
	Z float32 `json:"z" db:"z"`
}

Vec3 is a three dimensional vector.

	Y float64 `json:"y" db:"y"`
	Z float64 `json:"z" db:"z"`
}

func (Vec3f64) MarshalMUS

func (v Vec3f64) MarshalMUS(buf []byte) int

MarshalMUS fills buf with the MUS encoding of v.

func (Vec3f64) SizeMUS

func (v Vec3f64) SizeMUS() int
