Try to set the sprite on the course with the same slope as the line.  Like if the 
slope of the line you want him to follow is 1/2, you could start the sprite at the 
start of the line and move its x 2 spots and its y one, depending on the slope of 
the line.

To figure slope:  

(y of start point - y of end point)
(x of start point - x of end point)


To get the fractional portion of this right, you may not be able to do it on the 
computer; rather on paper or calculator that can give fractional answers.

This is the simpliest way to accomplish this.  Granted there are many more, but 
this is the simpliest.
