Examples

    PVector v1, v2;

    void setup() {
      smooth();
      noLoop();
      v1 = new PVector(40, 20, 0);
      v2 = new PVector(25, 50, 0);
    }

    void draw() {
      ellipse(v1.x, v1.y, 12, 12);
      ellipse(v2.x, v2.y, 12, 12);
      v2.add(v1);
      ellipse(v2.x, v2.y, 24, 24);
    }

    PVector v;

    void setup() {
      smooth();
      noLoop();
      v = new PVector(40, 20, 0);
    }

    void draw() {
      ellipse(v.x, v.y, 12, 12);
      ellipse(25, 50, 12, 12);
      v.add(25, 50, 0);
      ellipse(v.x, v.y, 24, 24);
    }

    PVector v1, v2;

    void setup() {
      smooth();
      noLoop();
      v1 = new PVector(40, 20, 0);
      v2 = new PVector(25, 50, 0);
    }

    void draw() {
      ellipse(v1.x, v1.y, 12, 12);
      ellipse(v2.x, v2.y, 12, 12);
      PVector v3 = PVector.add(v1, v2);
      ellipse(v3.x, v3.y, 24, 24);
    }

Description | Adds x, y, and z components to a vector, adds one vector to another, or adds two independent vectors together. The version of the method that adds two vectors together is a static method and returns a PVector, the others have no return value -- they act directly on the vector. See the examples for more context.

Syntax

    vec.add(x, y, z)
    vec.add(v)
    PVector.add(v1, v2)

Parameters

vec | any variable of type PVector
x | float: the x component of the vector
y | float: the y component of the vector
z | float: the z component of the vector
v | PVector: the x, y, and z components of a PVector object
v1 | PVector: the x, y, and z components of a PVector object
v2 | PVector: the x, y, and z components of a PVector object
vec | any variable of type PVector

Returns | None or PVector
Usage | Web & Application
