When doing time based animation, do you just set a rate at which an object moves, or is there some other way of doing it?

newPos += (velocity * deltaTime);

That''s what i do...
Everything are vectors. velocity is in points/s. deltaTime are seconds elapsed since the last frame.

That is one way of doing it. You can also do the keyframing method, where you have a set start position and a set ending position, and the time you want to take between them. Then, each frame, you decide where the object should be depending on how much time has passed.
