when i run my code, why does the ellipse/circle not show up

Question

from math import sin
from processing import *

X = 30
Y = 30
delay = 16
radius = 30

def setup():
    strokeWeight(10)
    frameRate(20)
    size(500,500)

def sircle():
    global X, Y, radius
    background(100)
    fill(0,121,184)
    stroke(255)
    fc = environment.frameCount

    X += (mouse.x-X)/delay;
    Y += (mouse.y-Y)/delay;

    radius = radius + sin(fc / 4)

draw = sircle
run()

for some reason run() only creates the background. does anybody know how to call the function for sircle()?

Answer 1

I think the OP is referring this code

where it does seem correct that draw is being assigned the function variable sircle. Besides, its not like sircle() is returning anything that can be assigned to draw

Looking at the example code in the link I shared above, you need a line like

ellipse(X,Y,radius,radius)

at the end of your sircle function
