Class b2Transform

constructor

• new b2Transform(pos: b2Vec2, r: b2Mat22): b2Transform

• The default constructor does nothing (for performance).

  Parameters

  • pos: b2Vec2

    Position
  • r: b2Mat22

    Rotation

  Returns b2Transform

position

R

GetAngle

• GetAngle(): number

• Calculate the angle that the rotation matrix represents.

  Returns number

  Rotation matrix angle.

Initialize

• Initialize(pos: b2Vec2, r: b2Mat22): void

• Initialize using a position vector and rotation matrix.

  Parameters

  • pos: b2Vec2

    Position
  • r: b2Mat22

    Rotation

  Returns void

Set

• Set(x: b2Transform): void

• Sets the transfrom from a transfrom.

  Parameters

  • x: b2Transform

    Transform to copy values from.

  Returns void

SetIdentity

• SetIdentity(): void

• Set this to the identity transform.

  Returns void
