Help with a processing project

in Programming Questions • 4 months ago

I'm trying to create a button that is the first Image of a sequence of 8, when the Image is clicked it will play through the sequence once.

As of right now I have a rectangle as the place holder, Could anybody help me over this hurdle ?

float x = 400;

float y = 100;

float w = 30;

float h = 30;

float ranNum;

int ranNumRound;

PImage img;

void setup(){

size(800,500);

background(255);

stroke(0);

}

void draw(){

fill(0);

rect(x,y,w,h);

}

void mousePressed(){

if(mouseX>x && mouseX <x+w && mouseY>y && mouseY <y+h){

ranNum = random(9);

ranNumRound = round(ranNum);

println(ranNumRound);

img = loadImage("images/pic"+ ranNumRound +".gif");

tint(200,200,100,50);

image(img,random(width),random(height),img.width,img.height);

}

Unless you have thousands of images, it's better to load all of them upfront within setup()!

For that, create an Array w/ length enough to store all of your images.

Here's an example of it. I can't run it for I don't have your files:

final static short NUM_IMAGES = 8;
final PImage[] imgs = new PImage[NUM_IMAGES];

final static String FILE_NAME = "pic", FILE_EXT = ".gif";

final static short X = 400, Y = 100, W = 30, H = 30;

void setup() {
  size(800, 500);
  noLoop();

  loadImages();
}

void draw() {
  background(0);

  final int idx = frameCount % NUM_IMAGES;

  image(imgs[idx], X, Y);
}

void mousePressed() {
  redraw();
}

void loadImages() {
  final String path = dataPath(FILE_NAME);

  for (int i = 0; i != NUM_IMAGES; ++i)
    imgs[i] = loadImage(path + i + FILE_EXT);
}
