Class | PVector
Name | ### mult()
Examples |
    PVector v;

    void setup() {
      noLoop();
      v = new PVector(5, 10, 0);
    }

    void draw() {
      ellipse(v.x, v.y, 12, 12);
      v.mult(6);
      ellipse(v.x, v.y, 24, 24);
    }
    PVector v1;

    void setup() {
      noLoop();
      v1 = new PVector(5, 10, 0);
    }

    void draw() {
      ellipse(v1.x, v1.y, 12, 12);
      PVector v2 = PVector.mult(v1, 6);
      ellipse(v2.x, v2.y, 24, 24);
    }
Description | Multiplies a vector by a scalar. The version of the method that uses a float acts directly on the vector upon which it is called (as in the first example above). The versions that receive both a PVector and a float as arguments are static methods, and each returns a new PVector that is the result of the multiplication operation. Both examples above produce the same visual output.
Syntax |
    .mult(n)
    .mult(v, n)
    .mult(v, n, target)
Parameters |
n | float: the number to multiply with the vector
v | PVector: the vector to multiply by the scalar
target | PVector: PVector in which to store the result
Returns | PVector
