Class

PShape

Name

setVertex()

Examples
PShape s;

void setup() {
  size(100, 100);
  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 setVertex() method defines 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.setVertex(index, x, y)
sh.setVertex(index, x, y, z)
sh.setVertex(index, vec)
Parameters
sh PShape: any variable of type PShape
index int: the location of the vertex
x float: the x value for the vertex
y float: the y value for the vertex
z float: the z value for the vertex
vec PVector: the PVector to define the x, y, z coordinates
Returnsvoid
