    Methods

    isParallel
    (
    • v2
    • tolerance
    )
    Boolean

    Defined in lib/p5.play.js:373

    Ask whether a vector is parallel to this one.

    Parameters:

    • v2 p5.Vector
    • [tolerance] Number optional
      • margin of error for comparisons, comes into play when comparing rotated vectors. For example, we want <1, 0> to be parallel to <0, 1>.rot(Math.PI/2) but float imprecision can get in the way of that.

    Returns:

    Boolean
    transform
    (
    • transform
    )
    p5.Vector

    Defined in lib/p5.play.js:6378

    Transforms this vector by a 2D transformation matrix.

    Parameters:

    Returns:

    p5.Vector:

    this, after the change

    Static Methods

    p5.Vector.project
    (
    • a
    • b
    )
    p5.Vector

    Defined in lib/p5.play.js:358

    Projects a vector onto the line parallel to a second vector, giving a third vector which is the orthogonal projection of that vector onto the line.

    Parameters:

    • a p5.Vector
      • vector being projected
    • b p5.Vector
      • vector defining the projection target line.

    Returns:

    p5.Vector:

    projection of a onto the line parallel to b.

    p5.Vector.transform
    (
    • v
    • t
    )
    p5.Vector

    Defined in lib/p5.play.js:6364

    Applies a 2D transformation matrix (using homogeneous coordinates, so 3x3) to a Vector2 (<x, y, 1>) and returns a new vector2.

    Parameters:

    Returns:

    p5.Vector:

    a new vector
