Uniform movement

Sorry if this has been asked before.

How do you make it so that when an object moves, the player will move with it? Is this possible?

Like say I just took a 5x5 from PHX and attached some thrusters to make a moving platform. As it is now, the platform will move and I will slide off of it. I want to make it so I move right along with it, if possible.

Hao?

For thanks, you can see Steam create a time warp on my computer:

EDIT: O dang sorry. Its slightly in the wrong section. Can a mod plz move this? ._.

If you mean be able to stand on it like normal ground, but while it’s moving, you can’t. Your best bet is to just go with the age old method of welding a seat to it.
