Updating Collision?

So I just finished all the beginner tutorials and decided to do some experimenting on my own. I copied Hello Collision (https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:beginner:hello_collision) and tacked on some code to simpleUpdate() that would translate both the player and rootNode scene only to find that the collision was left behind. How do I go about updating the collision (preferably in a fast and resource efficient way)? Any suggestions, simpler tutorials or keywords on the subject that I could look up would be great.

Also being new to the forum how do I uncheck the “This is a support topic” when submitting a post, I don’t want to be a nuisance to the developers.

What do you mean “left behind” ?

As for the support thing, I think you can edit it after submitting it.

How are you translating it? unless its kinematic you should translate/apply forces/walk direction to the physics controls not the spatial
