Hi there,

I am trying to create some kind of assembly line. When an object falls down on a FBox, it should stay at the position where it landed.

To illustrate my Question, I altered the ContactRemove sample from the library a bit. I want the circles to stay on the black box when I move it, and not to fall down:

1. import fisica.*;
2. FWorld world;
3. FBox pala;
4. void setup() {
5.   size(400, 400);
6.   smooth();
7.   Fisica.init(this);
8.   world = new FWorld();
9.   pala = new FBox(150, 20);
10.   pala.setPosition(width/2, height - 40);
11.   pala.setStatic(true);
12.   pala.setFill(0);
13.   pala.setRestitution(0);
14.   world.add(pala);
15. }
16. void draw() {
17.   background(255);
18.   if (frameCount % 25 == 0) {
19.     FCircle b = new FCircle(30);
20.     b.setPosition(random(0+10, width-10), 50);
21.     b.setVelocity(0, 200);
22.     b.setRestitution(0);
23.     b.setNoStroke();
24.     b.setFill(200, 30, 90);
25.     world.add(b);
26.   }
27.  
28.   pala.setPosition(mouseX, height - 40);
29.  
30.   world.draw();
31.   world.step();
32. }

So is there any easy way to add some kind of Inertia? For now I'm working on a solution with FDistanceJoints when a Circle hits the Box, but it really isn't a pleasure..

Thanks in advance!!
