Hi! I would like to know how can I change an image every 5 minutes (like a screensaver). Can I use "minute()" ?

What I want to do :

int m = minute();
for(m=0,m<5,m++){
// Here I load an image.
}

Is this code right?

Thanks !

Bas' version works great.

One thing you want to consider though, is to keep your code scalable. You should try to make your program work for 3 but also for 300 images, without the need to rewrite many lines of code.

Here's my approach:

Code:

// set how many images you want to cycle
int maxImages = 3; 

PImage img; 
int num = 1; 

void setup() { 
  size(100,100); 
} 

void draw() { 

  img = loadImage("image"+num+".gif");
  image(img, 0, 0);
  
  num++;  
  if (num > maxImages) {
    num = 1;
  } 

  delay(1000*60*5);  
} 
 

Something that might not be too great, is that all images are loaded again and again, as opposed to once in Bas' version. But since you only refresh every 5 minutes, this is hardly going to be processor intensive.

cheers,

Code:

loadImage("image"+num+".gif"); 

results to: image1.gif, image2.gif,  image3.gif, and so on...

Sort your images and give them all same name, but with a uniqe accending number. The file extension must also be the same.


Good optimization dek.

Actually, I think that reloading the images is a great solution for large slide shows, where precision timing isn't required.

By only keeping one image in memory instead of 300 or 3000 you would save considerable amounts of memory.
