What happened to delay

StereoFrog

My head just hurts. If you do this it doesn't work right it just stuck until all letters are displayed and if you remove "while" it still doesn't work also x=1; is done so to test if in second draw re-run it works. You can actually fix this if you like moving entire app to side cuz when mouse holding app touches side of screen app works for that moment and it can't be still.

Chrisir

all drawing operations done within draw() are cumulated, and only the end result is displayed when draw() exits. So, actually, you paint each image in sequence, one over the others, then you display the end result, the last image.

if(x==1)
text("H",0,32);
if(x==2)
text("e",32,32);
if(x==3)
text("l",64,32);
if(x==4)
text("l",96,32);
if(x==5)
text("o",128,32);
if(x==6)
text("!",160,32);
 x=x+1;
  delay(1000);

Moral of the story don't try shortcuts just go longer way (>_<). Also thanks mate.

Delay is not recommended anyway

Instead build a timer and increase x when the is met (every second)

@StereoFrog -- Or use the built-in frameRate() to set the draw speed and the built-in frameCount as the timer.

You could use an array of chars or a String to do this:

char[] cs = {'H', 'e', 'l', 'l', 'o', '!'};
String s = "Hello!";

void setup() {
  size(300, 100);
  textSize(32);
  frameRate(1); // draw ~1/sec
}
void draw() {
  background(0);

  // draw characters
  for (int i=(frameCount-1)%cs.length; i>=0; i--) {
    text(cs[i], 32*i, 32);
  }

  // draw string
  text(s.substring(0, frameCount%(s.length()+1)), 0, 96);
}
