looping/useing delay() as framerate
Jun 1st, 2005, 4:07pm  
I got known the delay function, which is better I suppose than changing the framerate in the setup? I managed to trigger it once, but how can I loop it?
-
And I tried to understand this piece of code works but I dont get it. Can somebody help? I am really bad in maths.. and logical operations..

void draw(){
 image(images[frame], 0, 0);
 frame++;
 if (frame > end){
   frame = start;
 }
}

I want to randomize the play of the pics but, didnt managed it to work yet..

---
below the whole script.

int numFrames = 63;
int frame = 0;
int start = 0;
int end = 1;

PImage[] images = new PImage[numFrames];

void setup(){

 size(1000, 768);
 framerate(30);
 
 for(int i=0; i<numFrames; i++) {
   String imageName = "kk00" + ((i < 10) ? "0" : "") + i + ".gif";
   images[i] = loadImage(imageName);
 }


}

void draw(){
 image(images[frame], 0, 0);
 frame++;
 if (frame > end){
   frame = start;
 }
}

void keyPressed(){
 //play sequence 1 when "1" is pressed
 //play sequence 2 when "2","3","4" is pressed
 switch(key){
 case '1':
   start = 0;
   end = 1;
   break;
 case '2':
   start = 3;
   end = 5;
   break;
 case '3':
   start = 5;
   end = 7;
   break;
 case '4':
   start = 9;
   end = 11;
   break;
 case '5':
   start = 13;
   end = 19;
   break;
 case '6':
   start = 20;
   end = 30;
   break;
 case '7':
   start = 31;
   end = 34;
   break;
 case '8':
   start = 35;
   end = 40;
   break;
case '9':
   start = 41;
   end = 44;
   break;
case '0':
   start = 45;
   end = 55;
   break;
 case 'o':
   start = 56;
   end = 62;
   break;
    case 'p':
   start = 2;
   end = 3;
   break;
    case 'l':
   start = 4;
   end = 62;
   break;
   case 'ö':
   delay(440);  
   break;
   case 'ä':
   delay(4040);  
   break;
 }
}

if you want a random image displayer with frames:

Code:

void draw()
{
 image(images[(int)random(0,numFrames)],0,0);
 delay(300);
}


the way you've coded it, is for displaying animations or straight forward slideshows..

oo thank u!
so how could I switch between the two options?
I mean the random mode and the normal mode.

Code:

boolean randomizer = false;

void draw(){
  if(!randomizer){
   image(images[frame], 0, 0);  
   frame++;  
   if (frame > end){  
     frame = start;  
   }
  }else{
   image(images[(int)random(0,numFrames)],0,0);
  }
  delay(300);  // have this here if you want delay on both straight forward and random, or move it one line up if you just want it on the random one..
}

void keyPressed()
{
switch(key){  
 case ' ':
 randomizer = !randomizer;
 break;
}
}
