creating png animation through array
Oct 14th, 2009, 6:08am  
I´m trying to make a small animation for a game using 3 pngs and looping them through an array but I can´t seem to get it to work.

CODE:

int numFrames = 3;

PImage[] images = new PImage[numFrames];

void setup(){
 size(400, 400);
 frameRate(1);
 images[0] = loadImage("0.png");
 images[1] = loadImage("1.png");
 images[2] = loadImage("2.png");
}

void draw(){

for (int i = 0; i < images.length; i++){
image(images[i], 0,0,100,100);
loop();
}


All the pics load on top of each other instead of one at a time. Any help is appriciated ^^

Some problems:
- In draw(), you load again the images (a bad idea... Smiley).
- In draw(), you don't display the images...
- And why do you use loop()?
- When you get an error, please try and show the exact message... Smiley I don't understand the one you report.

And a hint:
Don't loop in draw(), increment a (global) counter (restarting at zero after numFrames) and display the current image. draw() is a kind of loop in itself.

[EDIT] You changed the code while I was typing the answer above... So you fixed some of the problems! Good. I leave the list as it is of general interest (common gotchas).
The hint is still usable... Cheesy

I got it to work using sequencing Smiley thank you for the tips.


CODE:
frame = (frame+1) % numFrames;

that solved it Cheesy
