Need an algorithm for a simple problem!!

I need some kinda algorithm for this problem. I have x1 and x2 and between them is a rope. Look at this picture to give you a better idea: I have tried to solve it by subtracting an acceleration in the beginning and end like this: ..... . . . . . . . . . . . ..... and then lowering it in the same way, but I haven't succeeded. I just need a for-loop or something that would first lower the points. Let's say we have 50 for(i=0;i<50;i++) { point[i].x = ????? point[i].y = ????? } And I can't make it like: k=20; point[1].y+=k; k--; point[2].y+=point[1].y+k; k--; point[3].y+=point[2].y+k; because then there will be less points in the beginning and there will be holes between the "balls" that the rope is made of(fig. 4). How would you do it. Pleease help, it has been bothering me for days /MindWipe "If it doesn't fit, force it; if it breaks, it needed replacement anyway."

One method that would look real nice is called Verlet integration (search on Verlet and Hitman) which was used in the Hitman engine. There is a nice paper out there that tells you how to do it, the method is almost trivial to implement and produces quite nice physics results - and is esp good for strings.

- L = PI / (number of points-1).

Just a quick thing, if the # of points is variable then make sure it''s not zero otherwise you might get a divide by zero error.
