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), and therefore has no return value. The versions that receive both a PVector and a float as arugments 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
Returnsvoid or PVector
