PImage - Array reverse

Processing Coding Questions

Hi Guys, I have a little troubleshooting with a PImage…
The code works but i really wonder how to change the direction of the pictures.
Starting mouseY on top with numb 22 going down to 0.
( I just managed to start the array with 0 going down to 22 ).
Since i tried the whole day to find the solution, i hope you could help me:

PImage[] images;
int numImg = 22;




void setup() {

  background(255);
  size(944, 944);
  images = new PImage [numImg]; 

  for (int a=0; a<numImg; a++) {
    images[a] = loadImage("smile-" + a +".png" );
  }
}

void draw() {
  background(255);
  int imgNr = int(map(mouseY, 0, width, 0, numImg));
  translate(width/2, height/2);
  imageMode(CENTER);
  image(images[imgNr], 0, 0);
}

//All the best Iheartart

please format your code posting by pasting it into the

</> code button

of the editor header menu ( context name: Preformatted text )
it looks like
```
type or paste code here
```

also can use the ``` manually above and below your code.

thank you.

if you ask about the load Image sequence?

for (int a=0; a<numImg; a++) {

did you try ?

for (int a=numImg-1; a>=0; a--) {

Sorry, didn´t knew it.
The animation works with your variable aswell but it didn´t change the direction of the sequenz.

no problem, please edit your first post now. ( not make an new post for it )

please more detail about your question,

for (int a=0; a<numImg; a++) {
images[a] = loadImage(“smile-” + a +".png" );
}

possibly

for (int a=0; a<numImg; a++) {
images[numImg-1-a] = loadImage(“smile-” + a +".png" );
}

I see, its the double subtraction whitch changes the direction, right ?
