You know how there is an option to put an object "behind" everything in pivot? When do you decide if the thing is in-front or behind the stickman?

if everything is black, it won't matter to someone watching the animation.
if theres different colored objects, then it's going to matter what's in front and what's in back.

It's easiest to decide after you've animated, otherwise the dots of the thing you're putting it behind will take priority over the thing you're trying to animate and everything will be buggered up.
