Hi,
I'm trying to create a granular effect on a 15x15 cloner grid made of 2x2 cm planes spaced 21 mm apart. I want the clones to move instantly to Y = 20000 as a Linear Field passes over them from left to right. However, I want the movement to be disordered and progressively delayed, not all clones jumping at once.

For example, as the Linear Field touches the first column, only some of the clones should move to Y20000, and the others with some delay. When it touches the second column, some of the second and some of the first should move, and so on — creating a granular and organic transition.

I tried using a Delay Effector, but when it is active, the Linear Field seems to stop working.
I can't figure out where I'm going wrong. Any help would be appreciated!

Thanks in advance,Test move.c4d

@ferdinand Thanks, Ferdinando. The code was written by the AI. Basically, I wanted a certain number of 2cm x 2cm planes to move randomly along the Y axis. My original grid contains 62,000 of them, but for convenience, the one I posted contains 150. Since my view is oriented in a certain way, as the clones move, they'll disappear from the scene, creating a sort of shimmering or swarming fade-out effect.

Hello, in theory, the Python code linked to the Python effector should randomly move the object in the cloner by 100 cm along the Y axis — why isn't it working

import c4d
import random

def main() -> bool:
    md = c4d.modules.mograph.GeGetMoData(op)
    if md is None:
        return True

    count = md.GetCount()
    matrices = md.GetArray(c4d.MODATA_MATRIX)

    # Inizializza la lista dei frame solo una volta
    if not hasattr(op, "frames"):
        random.seed(42)
        op.frames = [random.randint(0, 75) for _ in range(count)]

    fps = doc.GetFps()
    current_frame = doc.GetTime().GetFrame(fps)

    for i in range(count):
        if current_frame >= op.frames[i]:
            # Sposta il clone fuori scena (es. +100 cm su Y)
            m = matrices[i]
            m.off.y = 100
            matrices[i] = m
        else:
            # Mantieni la posizione originale (nessuna modifica)
            pass

    md.SetArray(c4d.MODATA_MATRIX, matrices, True)
    return True
