Xpresso. Cloner objects disappearance

#1

I have a simulation where the cloner objects fly to the attractor, surrounded by the collider body.
And it is possible to create a scene with Xpresso where indexed cloner objects one by one disappear (scale from 1 to 0) when they collide with the collider?
I’m bad with Xpresso, I will be glad if someone can create the scene.
I tried to do a trick with the plain and field where the scale of the clones is changed to 0, but it does not work always properly.
