Functions

Private angleRight

angleRight(v: VectorLike): number

- Defined in functions.ts:81
Find angle (in radians) between vector and right vector, [1, 0].

Parameters
- v: VectorLike
  
  Target vector
Returns number

Angle in radians

Private cross

cross(a: VectorLike, b: VectorLike): number

- Defined in functions.ts:71
Find the cross product between two 2d vectors.

Parameters
- a: VectorLike
  
  Left operand
- b: VectorLike
  
  Right operand
Returns number

Signed area of the parallellogram defined by v1 and v2

Private lerpRot

lerpRot(a: any, b: any, n: number, target?: any): Vector2

- Defined in functions.ts:113
Rotates a vector, v1, towards a second vector, v2, based on a factor, n. An n-value of 0.5, will return a vector with rotation in between v1 and v2.

Parameters
- a: any
  
  Vector to interpolate from
- b: any
  
  Vector to interpolate to
- n: number
  
  Value between 0 - 1 used for interpolation
- Default value target: any = a
  
  Target for storing the results (Default: a)
Returns Vector2

Interpolated vector

Private rotate

rotate(v: Vector2, rad: number, target: Vector2): Vector2

- Defined in functions.ts:14
Rotate vector by a given amount of radians.

Parameters
- v: Vector2
  
  Vector to rotate
- rad: number
  
  Angle in radians
- target: Vector2
  
  Target for storing the results
Returns Vector2

- Defined in functions.ts:44
Flip/Rotate vector by 180 degrees.

Parameters
- v: Vector2
  
  Vector to rotate
- target: Vector2
  
  Target for storing the results
Returns Vector2
