Hi there! I have a question about how to save some images.
What I'm trying is that every time the user presses Ctrl + S to save the image processing save with name image-0001.png and then when the user presses again  Ctrl + S image-0002.png. How do I can do this?
I'm using the code below and what happens with this is that the image is saved with the number of the frame:

1. 
   boolean[] keys = new boolean[526];
   boolean checkKey(int k)
   {
     if (keys.length >= k) {
       return keys[k];
     }
     return false;
   }
   
   void keyPressed() {
   
     keys[keyCode] = true;
     println(KeyEvent.getKeyText(keyCode));
     if (checkKey(CONTROL) && checkKey(KeyEvent.VK_S)) {
       println("CTRL+S");
       saveFrame("Block_Mania-####.png");
     }
   }
