Can anyone tell me how to install the chatbot library, I have installed Eliza previously but the chatbot download does not seem to be in the library format.

camera movement altering transformations

I have written a program that builds a cube out of multiple boxes.
Another box impacts on the cube and causes the boxes to spread.

This code works fine as long as you don't move the camera but if I rotate the camera in any way while the box is impacting with the cube the boxes redraw in very strange places. If the camera is moved after the impact there is no problem.

I have tried OCD and PeasyCam but they both seem to have the same problem - is this a modelX problem?
1. import processing.opengl.*;
3. import peasy.*;
4. PeasyCam cam;
6. PVector v1,v2,v3;
7. //moving box position
8. float boxposition =-40;
9. //sets size of cube
10. int gridsize = 9;
11. //create array for cube
12. float[][]pntArray = new float[gridsize*gridsize*gridsize][3];
15. void setup(){
16. size(640, 800,OPENGL);
17. stroke(0);
19. //populate the cube array
20. int m = 0;
21. for(int i = 0; i<pow(gridsize, 3); i++){
22. pntArray[i][0] = (floor(i/(pow(gridsize, 2))))*10;
23. pntArray[i][2] = (i%gridsize)*10;
24. if(pntArray[i][2]==(gridsize-1)*10){
25. m+=1;
26. }
27. if(m==gridsize){
28. m=0;
29. }
30. pntArray[i][1] = m*10;
31. }
33. cam = new PeasyCam(this, 500);
34. cam.setMinimumDistance(250);

46. // move box
47. pushMatrix();
48. translate( v2.x,v2.y,v2.z);
49. fill(0,255,0);
50. box(10);
51. popMatrix();
53. //scroll through boxes in cube
54. for(int i = 0; i<pntArray.length; i++){
56. // set v1 to current cube section
57. PVector v1 = new PVector( pntArray[i][0], pntArray[i][1], pntArray[i][2]);
59. //clacuate distance between moving box and cube section
60. float d = PVector.dist(v1, v2);
62. fill(255);
63. //if block is close
64. if(d <20){
65. // create new vector v3 between moving box and cube section
66. PVector v3 = PVector.sub(v1, v2 );
68. // lengthen the vector to create impact
69. v3.mult(1.03);
71. // draw the new impacted section
72. pushMatrix();
73. translate(v2.x,v2.y,v2.z);

85. else{
86. //draw cube sections that are unaffected
