mouseButton

[brendanstuff]

from processing import *
from random import randint
x = 0
y = 0
def setup():
    size(1920,1080)
def draw():
    pass
def mousePressed():
    global x, y
    if mouseButton == LEFT:
        x += float(mouse.x - x)
        y += float(mouse.y - y)
        rect(x - 25, y - 25, 50, 50)
run()

throws us: Uncaught NameError: name 'mouseButton' is not defined on line 11

Came across this doing something my friend challenged me to do (we're both new to coding).

That example doesn't even run, as the function run() isn't defined, and neither is mouse, so that NameError can't be thrown. This program works for me:

def setup():
    size(400, 400)

def draw():
    pass

def mousePressed():
    if mouseButton == LEFT:
        rect(mouseX - 25, mouseY - 25, 50, 50)
