Hi folks,

I was wondering how to keep the code active, so to say.

Means that it does not only initialize but is active every frame.

I just want a random movement over time for one particle.

Here is the Code (sorry it's in german for personal learning purposes)

import c4d
import random

stepSize = 5
tp.AllocParticles(1)

v_vector = c4d.Vector()

v_vector.x = float(0)
v_vector.y = float(0)
v_vector.z = float(0)

z=0

def haupt(z,v_vector) :
  while z<10000 :
      direction = random.randrange (0,8,1)
      zufallsrichtung (direction)
      tp.SetPosition(0, v_vector)
      z += 1
      print direction
  return direction

def zufallsrichtung (direction) :

if direction == 0:  # Norden
      v_vector.y += stepSize

elif direction == 1: # Nordost
      v_vector.x += stepSize
      v_vector.y += stepSize
   
  elif direction == 2: # Ost
      v_vector.x += stepSize

elif direction == 3: # Südost
      v_vector.x += stepSize
      v_vector.y -= stepSize

elif direction == 4: # Süd
        v_vector.y += stepSize

elif direction == 5: # Südwest
      v_vector.x -= stepSize
      v_vector.y -= stepSize

elif direction == 6: # West
        v_vector.x -= stepSize;

elif direction == 7: # Nordwest
        v_vector.x -= stepSize;
        v_vector.y += stepSize;

def main() :
  pass

haupt(z,v_vector)

Hope someone can help me out of this tiny problem
