Class

PShape

Name

getVertex()
Examples
PShape s;

void setup() {
  size(100, 100, P2D);
  s = createShape();
  s.beginShape();
  s.vertex(0, 0);
  s.vertex(60, 0);
  s.vertex(60, 60);
  s.vertex(0, 60);
  s.endShape(CLOSE);
}

void draw() {
  translate(20, 20);
  for (int i = 0; i < s.getVertexCount(); i++) {
    PVector v = s.getVertex(i);
    v.x += random(-1, 1);
    v.y += random(-1, 1);
    s.setVertex(i, v);
  }
  shape(s);
}
Description The getVertex() method returns a PVector with the coordinates of the vertex point located at the position defined by the index parameter. This method works when shapes are created as shown in the example above, but won't work properly when a shape is defined explicitly (e.g. createShape(RECT, 20, 20, 80, 80).
Syntax
sh.getVertex(index)
sh.getVertex(index, vec)
Parameters
sh PShape: any variable of type PShape
index int: the location of the vertex
vec PVector: PVector to assign the data to
ReturnsPVector
