The game I am developing is in which you defend the Cell from the Viruses, and I need the sprites to have a MouseListener for when the mouse clicks on that sprite, it will get destroyed, and I cannot figure out how to get the location of the mouse and apply it to the sprite.

Basically, I need to grab the location of the mouse and the sprite, and when the user clicks it will reset the sprite.

I have tried to do debugging with this, so like if the mouse hovers the location of the sprite it will print a message "Hovering" but it just doesn't work.

For my update method, I added:

if(MouseInfo.getPointerInfo().getLocation() == this.getLocation()) System.out.println("SAME LOCATION");

I even got it to print out the location of the sprite and the mouse, and I aligned them both to 0,0 and it still didn't work.

How do I check if the location of the mouse is the same as a sprite, and then print out a message to the console?


If I understand your approach and problem correctly, you should use the following algorithm:

Obtain the minimum and maximum coordinates of the sprite.
Obtain the position of the mouse pointer.
Test both axes within a range.

The first requires the dimensions of the sprite and it's position. Let's say its position is relative to the top-left of the sprite. Pseudo-code would look like this (my Java is rusty):

int minx = this.getPosition().x();
int miny = this.getPosition().y();
int maxx = minx + this.getWidth();
int maxy = miny + this.getHeight();

int mousex = MouseInfo.getPointerInfo().getLocation().x();
int mousey = MouseInfo.getPointerInfo().getLocation().y();

if ((mousex >= minx && mousex <= maxx) && (mousey >= miny && mousey <= maxy) {
    System.out.println("Clicked on the sprite.");
    // Some reset code.
  • \$\begingroup\$ Yes this does work, thank you for that! The only error that occurs is that the mouse gets the screen locations, and not the JFrame locations. How would I add into the method to get the literal location on the screen? \$\endgroup\$ – Shzylo Oct 1 '13 at 22:04
