Types

type Contact

type Contact struct {
	Point  math32.Vector3
	Normal math32.Vector3
	Depth  float32
}

Contact describes a contact point, normal, and depth.

type Matrix

type Matrix [][]bool

Matrix is a triangular collision matrix indicating which pairs of bodies are colliding.

func NewMatrix

func NewMatrix() Matrix

NewMatrix creates and returns a pointer to a new collision Matrix.

func (*Matrix) Get

func (m *Matrix) Get(i, j int) bool

Get returns whether i and j are colliding.

func (*Matrix) Reset

func (m *Matrix) Reset()

Reset clears all values.

func (*Matrix) Set

func (m *Matrix) Set(i, j int, val bool)

Set sets whether i and j are colliding.
