Py5Shape.get_vertex()

Py5Shape.get_vertex()#

The get_vertex() method returns a Py5Vector with the coordinates of the vertex point located at the position defined by the index parameter.

Examples#

def setup():
    global s
    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 get_vertex() method returns a Py5Vector 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, but won’t work properly when a shape is defined explicitly (e.g. create_shape(RECT, 20, 20, 80, 80).

Underlying Processing method: PShape.getVertex

Signatures#

get_vertex(
    index: int,  # vertex index
    /,
) -> Py5Vector

get_vertex(
    index: int,  # vertex index
    vec: Py5Vector,  # target object to place vertex coordinates into
    /,
) -> Py5Vector
