load image progression
Nov 20^th, 2007, 10:07pm

this is veeeery simple, but it would help me to understand how this works..

i am trying to load and display a series of images that i have in the sketch book, their names are: 1.jpg, 2.jpg, 3.jpg...

i want to load and display them one by one, by clicking the mouse... but this is not working...??

PImage a;
void setup(){
size(1200,900);
a = loadImage("1.jpg"); // Load the images into the program
image(a, 0, 0, width, height);
noLoop();
}
for(int p=1; p<100; p=p+1) {
}
void mouseClicked(){
String r=p+".jpg";
PImage b;
b = loadImage(r); // Load the images into the program
image(b, 0, 0, width, height);
}

try this!

Code:


PImage a;
int p = 0; //initialize a counter
int numberOfImages = 3; //total number of images in the folder

void setup(){
  size(1200,900);
  a = loadImage("1.jpg"); // Load the images into the program
  image(a, 0, 0);
}

void draw() {
}

void mouseClicked(){
  p+=1; //add to the counter
  String r = ((p%numberOfImages) +1) + ".jpg"; //the p%numberOfImages loops through your images (1,2,3... 1,2,3, etc)
  a = loadImage(r); // Load the images into the program
  image(a, 0, 0);
}

The for loop in your code does nothing.
Also in order to detect the mouse clicks, you can't use noLoop().. but you can keep the draw() empty.
