hello,

like this....

[not tested]

• you could also use an arraylist instead of array
• you could also use a String and just add the latest input (like this:  input+=key; )

1. String [] input = new String [20];
2. int counter = 0;
3. 
   
4. void draw() {
5. 
   
6. fill (255,2,2);
7. if (input[0] != null )   
8.      text(input[0],20,20);
9. 
   
10. fill (2,2,255);
11. if (input[1] != null )   
12.      text(input[1],40,20);
13. 
    
14. // etc.
15. // .............// or use a for loop later
    
16. 
    
17. if (keyPressed) {
18.     input[counter] = key;
19.     counter++;
20. } // if
21. 
    
22. } // func

this works but is much more complicate than expected..... 

since the speed of blinking is diffrent, each letter brings its own
timer and two colors....    

1. //
2. char  [] input = new char [20];
3. color [] inputColors = new color [input.length];
4. color [] inputColors2 = new color [input.length];
5. int   [] timer   = new int  [input.length];
6. int   [] delayTime = new int  [input.length];
7. boolean[] brightColors   = new boolean  [input.length];
8. //
9. int counter = 0;
10. //
11. //
12. void setup()
13. {
14.   size (880, 880 );
15.   textSize(34);
16.   for (int i = 0 ; i < input.length; i++) {
17.     inputColors[i] = color (random(0, 255), random(0, 255), random(0, 255));
18.     inputColors2[i] = color (random(0, 255), random(0, 255), random(0, 255));
19.     delayTime [i] = int( random (100, 5000));
20.   }
21. }
22. //
23. void draw() {
24.   background (111);
25.   for (int i = 0 ; i < input.length; i++) {
26.     if ((timer[i]+ delayTime [i] )<millis()) {
27.       brightColors[i]=!brightColors[i];
28.       timer[i]=millis();
29.     }
30.     if (brightColors[i])
31.       fill ( inputColors[i] );
32.     else
33.       fill ( inputColors2[i] );
34.     if (!(trim(str(input[i])).equals("")))  
35.       text(input[i], 22*i+11, 40);
36.   } // for
37. } // func
38. //
39. void keyReleased () {
40.   if (counter < input.length) {
41.     input[counter] = key;
42.     counter++;
43.   } // if
44. }

Hi,

new version

you can now even use RETURN

inputColors2 and inputColors are the two colors he toggles between.
I set one to black now, one to white.

He toggles between them depending on brightColors:

1.     if (brightColors[i])
2.       fill ( inputColors[i] );
3.     else
4.       fill ( inputColors2[i] );

entire sketch - see bold for what's new :

1. //
2. char  [] input = new char [520];  // that was too small !!!!!!!!!!!!!!!!!!!!
   
3. color [] inputColors = new color [input.length];
4. color [] inputColors2 = new color [input.length];
5. int   [] timer   = new int  [input.length];
6. int   [] delayTime = new int  [input.length];
7. boolean[] brightColors   = new boolean  [input.length];
8. //
9. int counter = 0;
10. //
11. //
12. void setup()
13. {
14.   size (880, 880 );
15.   textSize(34);
16.   for (int i = 0 ; i < input.length; i++) {
17.     inputColors[i] =  color (255);  // white  // color (random(0, 255), random(0, 255), random(0, 255));
18.     inputColors2[i] = color (0);    // black  // color (random(0, 255), random(0, 255), random(0, 255));
19.     delayTime [i] = int( random (100, 5000));
20.   }
21. }
22. //
23. void draw() {
24.   background (111);
25.   int h = 40; // y / line number
26.   int a = 10; // x       22*i+10;
27.   for (int i = 0 ; i < input.length; i++) {
28.     if ((timer[i]+ delayTime [i] )<millis()) {
29.       brightColors[i]=!brightColors[i];
30.       timer[i]=millis();
31.     }
32.     if (brightColors[i])
33.       fill ( inputColors[i] );
34.     else
35.       fill ( inputColors2[i] );
36.   
    
37.     if (input[i]== ENTER || input[i] == RETURN) {
38.       // new line
39.       a=10;
40.       h = h+40; // y-value / line
41.     }
42.     else if (!(trim(str(input[i])).equals(""))) { 
43.       text(input[i], a, h);
44.     }
45.     a=a+22; // x-value
46.     if (a > width-30) {
47.       // new line
48.       a = 10;
49.       h = h+40; // y-value / line
50.     }
51.   } // for
52. } // func
53. //
54. 
    
55. void keyReleased () {
56.   if (counter < input.length) {
57.     input[counter] = key;
58.     counter++;
59.   } // if
60. }
61. //

Thanks a lot !
