So I have a class dealing with buttons and I have an array of rectangles containing 2 individual rectangular shapes. Now when I make a variable which retrieves say the 0th index of the array it will give me a nullpointerexception I have been scratching my head over this I have clearly declared and initialised the array and made it the appropriate size for 2 rectangles to be contained and have assigned these to the indexes. I must be missing something really small which I can't seem to figure out.
Below I have put the relevant code for this:
public class MenuButton {
private int height;
private int width;
private float positionX;
private float positionY;
//private ArrayList<Rectangle> rects;
private Rectangle rects[];
private Rectangle play;
private Rectangle touchToPlay;
private boolean isTouched;
public MenuButton(int height, int width, float positionX, float positionY){
this.height = height;
this.width = width;
this.positionX = positionX;
this.positionY = positionY;
isTouched = false;
Rectangle rects[] = new Rectangle[2];
play = new Rectangle(positionX, positionY, width, height);
touchToPlay = new Rectangle(positionX, positionY, width, height);
//can clean this up by introducing initButtons() to assign buttons to
//indexes of the array
rects[0] = play;
rects[1] = touchToPlay;
}
public boolean isClicked(int index,float screenX, float screenY){
//ERROR IS BELOW THIS LINE
Rectangle rect = rects[0];
return rect.contains(screenX, screenY);
}
Youre shadowing the variable rects. Replace
Rectangle rects[] = new Rectangle[2];
with
rects = new Rectangle[2];
