a ball i made, was simply created using box's some are rotated to become slopes.

i then created a path, i did this by using a line tool and created the direction on whihc the ball will travel.

once i had finished this, i then made a sphere (ball) and clicking animation...constraints...path constraints. clicked the line.

i changed the time line to 500 frames rather then 100, i also had to increase the speed to x4 as it was to slow.

brief

The brief sounds interestings, and the fact tht theres no time limit for the clip is good. all the fable stories are very short so they will only be a few seconds long anyway.
