Adds a vertex to a custom shape.

`vertex()`

sets the coordinates of vertices drawn between the beginShape() and endShape() functions.

The first two parameters, `x`

and `y`

, set the x- and y-coordinates of the vertex.

The third parameter, `z`

, is optional. It sets the z-coordinate of the vertex in WebGL mode. By default, `z`

is 0.

The fourth and fifth parameters, `u`

and `v`

, are also optional. They set the u- and v-coordinates for the vertex’s texture when used with endShape(). By default, `u`

and `v`

are both 0.

## Examples

## Syntax

`vertex(x, y)`

`vertex(x, y, [z])`

`vertex(x, y, [z], [u], [v])`

## Parameters

x

Number:

x-coordinate of the vertex.

y

Number:

y-coordinate of the vertex.

z

Number:

z-coordinate of the vertex. Defaults to 0.

u

Number:

u-coordinate of the vertex's texture. Defaults to 0.

v

Number:

v-coordinate of the vertex's texture. Defaults to 0.
