Generate random number in Python Scripting

[Grzegorz Krzemien]

Hello,

It's my first post here, so please be gentle 🙂

I wanted to create my first script in Vectorworks using Python, simple Random Walker like this:
 

import random

size = 50
posX = 0
posY = 0
steps = 100

for i in range(steps):
    vs.Rect(posX, posY, posX + size, posY + size)
    r = random(4)
    if r == 0:
        posX += size
        posY += size
    if r == 1:
        posX -= size
        posY += size
    if r == 2:
        posX -= size
        posY -= size
    if r == 3:
        posX += size
        posY -= size

How can I create random int number in range 0 - 3 (0, 1, 2, 3).  Same code runs in processing.

There is this method in python, but it does not work in Vectorworks.

 randrange ([start,] stop [,step])

Thanks for any help!

Hello,

maybe you simply forgaot the "namespace" try this:

 

import random
print ( random.randrange (0, 500, 3) )

Maybe this will help - you need to use "random.randrange(value)"

 

import random

size = 50
posX = 0
posY = 0
steps = 100

for i in range(steps):
    vs.Rect(posX, posY, posX + size, posY + size)
    r = random.randrange(4) #corrected to include namespace
    if r == 0:
        posX += size
        posY += size
    if r == 1:
        posX -= size
        posY += size
    if r == 2:
        posX -= size
        posY -= size
    if r == 3:
        posX += size
        posY -= size

Thank you you PatW and Marissa, it's working now 🙂
