Hello,

 

I'm having problems trying to reach a variable set inside a Class, here is my code:

1.  
2. //declaration of object
3. Colores unColor;
4.  
5. void setup()
6. {
7. size(100, 300);
8. smooth();
9. frameRate(60);
10. background(226,225,215);
11. noFill();
12.  
13. // building array of colors
14. Colores colores = new Colores();
15. colores.buildColorTable();
16.  
17. //creation of object
18. unColor = new Colores();
19.  
20. //prints result
21. println(unColor.devuelveColor());
22.  
23. }
24.  
25.  
26. //----------- Class Colores -------->
27. public class Colores {
28. color elcolor;
29. PImage imagenDelMarActual;
30. int numColors = 100;
31. color[] coloress = new color[numColors];
32. int puntoX=100;
33. int puntoY=50;
34.  
35. Colores() {
36. imagenDelMarActual = loadImage("elmar.jpg");
37. }
38.  
39. void buildColorTable() {
40.  
41. elcolor = imagenDelMarActual.get(100,300);
42. float elrojo = red(elcolor);
43. float elverde = green(elcolor);
44. float elazul = blue(elcolor);
45. coloress[1] = color(117, 144, 173);
46. coloress[2] = color(82, 112, 138);
47. coloress[3] = color(82, 12, 18);
48. }
49.  
50. // the problem is here it returns 0 and not the color value
51. color devuelveColor() {
52. return coloress[2];
53.  
54. }
55. }

 

Can anyone tell me why devuelveColor() is returning 0?

I don’t really understand how to declare global variables inside a Class

It’s possible to declare a variable inside a class and get the data in another class?

I hope that my English is clear enough ; )

Thanks in advance!
