Push and pull object

Hello, I’m looking to create a box i can push and pull for my 3D side scroller game - i have found lots of tutorials online for this but they only work in first person games. Has anyone got any advice for this? or have done it before.
cheers

I would have the player push a button or something to go into push/pull mode, when this happens you can attach the object to a socket on the player. But there are a lot of other ways to do it too.
