How do I spawn a sprite continuously behind my hero sprite

I am in the process of creating my first game using C2. Please let me know how to do the following things in C2

1. When my hero moves in any direction, I want some other sprite to follow him, (spawn another sprite just behind the hero continuously) creating a path behind the my hero.

2. When my hero collide with the spawned sprite, it should bounce back or stay still

Hoping for your expert advice at the earliest

thanks in advance

Here is a basic example:
