Transform

Transform

Class representing a Transform. A Transform holds all the spacial information about an object (ex. position, rotating, size, etc.).

For performance reasons the transform also stores a list of corners to be able to quickly apply intersection testing.

Constructor

public Transform

new Transform(pos, size, angle)

Constructs a new Transform object.

Parameters

•  pos: Vector – The initial position of the transform.

•  size: Vector – The initial size of the transform.

•  angle: number – The initial angle of the transform.
