Hello,

I scripted a walker path using a class. So points are aggregating randomly on the w, y and z directions.

Then I would like to add a line between them (pt1 to pt2, pt2 to pt3, etc.).

So I added a definition for the line.

But it seems that the script doens’t recognize the variables defined just before, in the def point and def step.

So, I tried to return the values, but it doesn’t work. I really don’t know what to do now.

I putted in comment the part that doesn’t work.

Thank you for your help!

```
import rhinoscriptsyntax as rs
import random as r
import math as m
r.seed(1)
time = 100
class Aggregation:
def __init__(self):
self.x = 0
self.y = 0
self.z = 0
def point(self):
shape = rs.AddPoint(self.x, self.y, self.z)
return shape
def step(self):
stepX = r.uniform(-1,1)
stepY = r.uniform(-1,1)
stepZ = r.uniform(-1,1)
self.x += stepX
self.y += stepY
self.z += stepZ
"""return self.x
return self.y
return self.z
return stepX
return stepY
return stepZ
def line(self):
shape1 = (self.x, self.y, self.z)
shape2 = (stepX, stepY, stepZ)
lineShape = rs.AddLine(shape1, shape2)
return lineShape"""
a = Aggregation()
pList = []
for t in range(time):
a.step()
pList.append(a.point())
#pList.append(a.line())
a = pList
