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

- Defined in node_modules/@tawaship/box2dweb-module/types/box2dweb.d.ts:749
The default constructor does nothing (for performance).

Parameters
- pos: b2Vec2
  
  Position
- r: b2Mat22
  
  Rotation
Returns b2Transform

Properties

R

Transform rotation.

position

position: b2Vec2

Transform position.
