I want to have a bunch of blocks fall from the sky like rain then stack up when they hit the floor of the stage. anyone know how I would go about this?

I’m going to start by creating the blocks and then jamming them into an array from there i can control their falling speed but I don’t know where to start as far as the collision detection. I was initially thinking of using a hit test to stop the blocks when they hit each other but quickly realized that if they hit each other mid flight they would stop where they were
