Hi folks,

new to developping in Processing. Coming from full procedural environments, not quite used to OOP. Aaaaanyway.

I get an ArrayIndexOutOfBoundsException: 2 when interpreting this piece of code (sorry it's 91 lines long). The error occurs on line 57 as soon as I try to assign a value to a cell of the array:

1. // Declaring letter points matrix array
2. float[][][] let_mtrx = new float[2][2][1];
3. // General text angle
4. float ngl = 33.333;
5. 
   
6. // Letter dimensions
7. float let_w = 64;
8. float let_h = 96;
9. 
   
10. // Finding the angles of the letter's diagonals afer ngl, let_w and let_h
    
11. float let_ngl_1 = (atan(let_h/let_w))+ngl;
12. float let_ngl_2 = (PI-let_ngl_1)+ngl;
13. float let_ngl_3 = (PI+let_ngl_1)+ngl;
14. float let_ngl_4 = (PI*2-let_ngl_1)+ngl;
15. 
    
16. // Finding the angles of the letter's orthogonals afer ngl
    
17. float let_ngl_ortho_1 = ngl;
18. float let_ngl_ortho_2 = ngl+PI/2;
19. float let_ngl_ortho_3 = ngl+PI;
20. float let_ngl_ortho_4 = ngl+PI*1.5;
21. 
    
22. // Finding the different lengths from center (horizontal, vertical and diagonal)

I guess my array syntax is bad? Ideas anyone? Thx!
