Making something move relative to something else, but slower/shorter ?

Question

I have 2 objects, they both rotate the exact same, and can move in 3d space.

The 2nd object however, I want to move as well as the 1st object, but 1/100th or 1000th the speed, etc. So, can I just give Rigidbody B, Rigidbody A's velocity, or magnitude or something, divided by my movement speed ratio?

Sure, why not? Make a script and attach this to your 2nd object. Assign a public variable to let your 2nd object script reference 1st object's rigidbody. Then in Update() write this single line : gameObject.rigidbody.velocity = firstObject.rigidbody.velocity * ratio;

Now it will follow the first object at its speed.

Ah good. I wasn't sure if i could multiply/divide velocity, since its a vector4. will give it a try!

It is Vector3.

Just to keep you clear, a vector3 is a form of matrix so multiplications are limited but for integers and floats, which are simple scale calculations. For example, (a,b,c)*x == (ax,bx,cx).
