Problem for making a circle follow another...

Basicly, I need to math for a circle following another circle...no idea how to do that. I do scripts, but I'm not to great in math (well, math I haven't yet learned). If anyone can help please do so...(this is for...gah can't say....)

Just set the x and y the following circle is drawn to, to a certain point in the other circle and you're probably all set, you could make the one spin in the other too that way for snazzy 3dish effects.

Yes, but the reason I asked for the actually mathematical stuff is because its for a projectile. A magic, more exact, you played SC before? Well, if so, have you seen the reaver bullets? Basicly it makes a really cool effect with trailing circles, and it gave me a great idea...only problem is, I don't know how to do it. Bleh, I guess I will ask my math teacher or something...

Vector -

Mathematics.
A quantity, such as velocity, completely specified by a magnitude and a direction.
A one-dimensional array.
An element of a vector space.

Magnitude -

Mathematics.
A number assigned to a quantity so that it may be compared with other quantities.
A property that can be described by a real number, such as the volume of a sphere or the length of a vector.

Eh, now I need to decypher the meanings, althought I think I get it...

But, you gave me annoying math terms, when I've said math vocab is worthless...guess you have just proven me wrong. Damn that math vocab...

Like what do you mean by magnitude ?

You could solve it by using angles in the movement and make the following circle use the opposite angle, the angle minus pi.

But I just remembered it won't work because using that method you can only make straight lines. :(
