Dear all,
I'm having a problem writing my first class, I'm new to processing and I can't understand what I'm doing wrong.

This is what I want to do with my object
2. import processing.pdf.*;
4. PShape jup01;
5. float bx;
6. float by;
7. float bs = 50;
8. boolean bover = false;
9. boolean locked = false;
10. boolean attivo = false;
11. boolean record;
12. float bdifx = 0.0;
13. float bdify = 0.0;
14. float a = 0.0;
15. float s = 0.0;
16. int value = 0;
19. void setup() {
20. size(800, 500);
21. bx = 20;
22. by = 20;
23. smooth();
24. jup01 = loadShape("jup01.svg");
25. println(mouseX);
26. }
28. void draw(){
29. background(255);
30. if(record) {
31. beginRaw(PDF, "jupiter.pdf");
32. }
33. if (mouseX > bx && mouseX < bx+bs &&
34. mouseY > by && mouseY < by+bs) {
35. bover = true;
36. }
37. else {
38. bover = false;
39. }
40. //shape(jup01,bx,by,bs,bs);
41. scala();
42. stampa();
43. if(record) {
44. endRaw();
45. record = false;
46. }
47. }
49. void mousePressed() {
50. if(bover) {
51. locked = true;
52. } else {
53. locked = false;
54. }
55. bdifx = mouseX-bx;
56. bdify = mouseY-by;
57. }
58. void mouseDragged() {
59. if(locked) {
60. bx = mouseX-bdifx;
61. by = mouseY-bdify;
62. }
63. }
65. void mouseReleased() {
66. locked = false;
67. }
69. void keyPressed() {
70. if (key == CODED) {
71. if (keyCode == CONTROL) {
72. attivo = true;
73. }
74. } else {
75. attivo = false;
76. }
77. }
79. void keyReleased() {
80. if (value == 0) {
81. attivo = false;
82. } else {
83. value = 0;
84. }
85. }
87. void scala(){
88. if(attivo&locked) {
89. float zoom = mouseX-bx;
90. if(zoom > 50){
91. bs=zoom;
92. }
93. else {
94. bs=50;
95. }
96. shape(jup01,bx,by,bs,bs);
97. }
98. else {
99. shape(jup01,bx,by,bs,bs);
100. }
101. }
103. void stampa(){
104. if(keyPressed) {
105. if (key == 'P' || key == 'p') {
106. record = true;
107. } }}
And this is what I've done since now.. I can create the objects but they are not doing what I want.
2. icona icona1;
3. icona icona2;
5. void setup() {
6. size(800, 500);
7. smooth();
8. icona1 = new icona (loadShape("jup01.svg"),10.,10.,50.);
9. icona2 = new icona (loadShape("jup02.svg"),10.,50.,50.);
10. }
12. void draw(){
13. background(255);
14. icona1.display();
15. icona2.display();
16. }
18. class icona {
19. PShape jup_icona;
20. float bx;
21. float by;
22. float bs = 50;
23. boolean bover = false;
24. boolean locked = false;
25. boolean attivo = false;
26. boolean record;
27. float bdifx = 0.0;
28. float bdify = 0.0;
29. float a = 0.0;
30. float s = 0.0;
31. float value;
32. char nome;
34. icona(PShape tempnome,float tempbx, float tempby, float tempbs){
35. jup_icona=tempnome;
36. bx=tempbx;
37. by=tempby;
38. bs=tempbs;
39. }
41. void display(){
42. if (mouseX > bx && mouseX < bx+bs &&
43. mouseY > by && mouseY < by+bs) {
44. bover = true;
45. }
46. else {
47. bover = false;
48. }
49. if(attivo&locked) {
50. float zoom = mouseX-bx;
51. if(zoom > 50){
52. bs=zoom;
53. }
54. else {
55. bs=50;
56. }
57. shape(jup_icona,bx,by,bs,bs);
58. }
59. else {
60. shape(jup_icona,bx,by,bs,bs);
61. }
62. }
64. void mousePressed() {
65. if(bover) {
66. locked = true;
67. } else {
68. locked = false;
69. }
70. bdifx = mouseX-bx;
71. bdify = mouseY-by;
72. }
73. void mouseDragged() {
74. if(locked) {
75. bx = mouseX-bdifx;
76. by = mouseY-bdify;
77. }
78. }
80. boolean mouseReleased() {
81. return locked = false;
82. }
84. void keyPressed() {
85. if (key == CODED) {
86. if (keyCode == CONTROL) {
87. attivo = true;
88. }
89. } else {
90. attivo = false;
91. }
92. }
94. void keyReleased() {
95. if (value == 0) {
96. attivo = false;
97. } else {
98. value = 0;
99. }
100. }
102. }
Any suggestion?

Thank you very much!
