Hello,
I am trying to create a program that displays 6 rectangles, that change color when clicked. I have succeeded in drawing the rectangles, and the program responds when you click, but it changes the color of all of the rectangles. I am not sure how to get the program working properly. In the code I have included, I have the program set to change color when the upper left rectangle is pressed. Any advice would be much appreciated!
1. int width = 640;
2. int height = 480;
3. float red_channel = 255;
4. float green_channel = 255;
5. float blue_channel = 255;
7. void setup()
8. {
9. size(width, height);
10. }
12. void draw() {
14. rect(0, 0, width/3, height/2);
15. rect((width/3), 0, width/3, height/2);
16. rect(width-width/3, 0, width/3, height/2);
17. rect(0, height/2, width/3, height/2);
18. rect(width/3, height/2, width/3, height/2);
19. rect(width-width/3, height/2, width/3, height/2);
20. }
23. void mouseClicked()
24. {
25. if(mouseX < width/3 && mouseY < height/2)
26. {
27. red_channel = random(0, 255);
28. green_channel = random(0, 255);
29. blue_channel = random(0, 255);
31. fill(red_channel, green_channel, blue_channel);
32. rect(0, 0, width/3, height/2);
33. }
34. }
Thanks,

Trevor
