I try to find a more compact way for creating a custom 'pixel' font (because I need to process a whole alphabet this way).

When i select a character ( c='a') I want to loop the corresponding array with the for loop. Now I have a seperate rect for each character, because I don't know how to use the value of c as the name of the array (so I can say if value of c[i][j]{}).

Is this possible?

the 'problem' part:

full code:

2. 
       c = 'a';
3.     
4.     int[][] a = {  
5.       {0,0,0,0,0}, 
6.       {0,0,0,0,0}, 
7.       {0,1,1,1,0}, 
8.       {0,0,0,0,1}, 
9.       {0,1,1,1,1}, 
10.       {1,0,0,0,1}, 
11.       {0,1,1,1,1}, 
12.       {0,0,0,0,0}, 
13.       {0,0,0,0,0}
14.     };
15. 
    
16.     int[][] b = {  
17.       {1,0,0,0,0}, 
18.       {1,0,0,0,0}, 
19.       {1,1,1,1,0}, 
20.       {1,0,0,0,1}, 
21.       {1,0,0,0,1}, 
22.       {1,0,0,0,1}, 
23.       {1,1,1,1,0}, 
24.       {0,0,0,0,0}, 
25.       {0,0,0,0,0}
26.     };
27. 
    
28.     for (int i = 0; i < 9; i++) {
29.       for (int j = 0; j < 5; j++) {
30. 
    
31.         if (c=='a') {
32.           if (a[i][j]==1) {
33.             rect(x+j*40, i*40, 20, 20);
34.           }
35.         }
36.         if (c=='b') {
37.           if (b[i][j]==1) {
38.             rect(x+j*40, i*40, 20, 20);
39.           }
40.         }
41. 
    
42.       }
43.     }

Hello,

I working on a simple program as a part of a sound-reactive installation. Every time the sound velocity is more than 5, a rectangle comes in on the right, and all other objects shift one place to the left. 

The problem: the velocity is the width/height of the rectangles. Now it affects all objects, but I only want to assign the value to the newest, so all rectangles get their own size (and stay that size). Maybe there is something wrong with void show() and I tried things with an arraylist, but I'm afraid I'm a bit lost.

This is a simplified example to make it more clear, in the real version the rectangles are characters (kind of sound-reactive newsticker).

If anyone can point me in the right direction, that would be great :-)
