def setup():

    s = py5.create_shape()
    s.begin_shape()
    s.vertex(0, 0)
    s.vertex(60, 0)
    s.vertex(60, 60)
    s.vertex(0, 60)
    s.end_shape(py5.CLOSE)


def draw():
    py5.translate(20, 20)
    for i in range(0, s.get_vertex_count()):
        v = s.get_vertex(i)
        v.x += py5.random(-1, 1)
        v.y += py5.random(-1, 1)
        s.set_vertex(i, v)

    py5.shape(s)

Description

The set_vertex() 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, but won’t work properly when a shape is defined explicitly (e.g. create_shape(RECT, 20, 20, 80, 80).

Underlying Processing method: PShape.setVertex

Syntax

set_vertex(index: int, vec: Py5Vector, /) -> None
set_vertex(index: int, x: float, y: float, /) -> None
set_vertex(index: int, x: float, y: float, z: float, /) -> None

Parameters

  • index: int - the location of the vertex

  • vec: Py5Vector - the vector to define the x, y, z coordinates

  • x: float - the x value for the vertex

  • y: float - the y value for the vertex

  • z: float - the z value for the vertex
