The technology underlying the modern optical computer mouse is known as digital image correlation, a technology pioneered by the defense industry for tracking military targets. S5085 optical sensor IC die (CMOS sensor + driver) Other manufacturers soon followed Microsoft's lead using components manufactured by the HP spin-off Agilent Technologies, and over the next several years mechanical mice became obsolete. It worked on almost any surface, and represented a welcome improvement over mechanical mice, which would pick up dirt, track capriciously, invite rough handling, and need to be taken apart and cleaned frequently. The first commercially available, modern optical computer mice were the Microsoft IntelliMouse with IntelliEye and IntelliMouse Explorer, introduced in 1999 using technology developed by Hewlett-Packard. A surface-independent coherent light optical mouse design was patented by Stephen B. This advance enabled the mouse to detect relative motion on a wide variety of surfaces, translating the movement of the mouse into the movement of the cursor and eliminating the need for a special mouse-pad.
As computing power grew cheaper, it became possible to embed more powerful special-purpose image-processing chips in the mouse itself. Modern surface-independent optical mice work by using an optoelectronic sensor (essentially, a tiny low-resolution video camera) to take successive images of the surface on which the mouse operates.

Lyon of Xerox, used a 16-pixel visible-light image sensor with integrated motion detection on the same n‑type ( 5 µm) MOS integrated circuit chip, and tracked the motion of light dots in a dark field of a printed paper or similar mouse pad. Predictive algorithms in the CPU of the mouse calculated the speed and direction over the grid. One of these, invented by Steve Kirsch of MIT and Mouse Systems Corporation, used an infrared LED and a four-quadrant infrared sensor to detect grid lines printed with infrared absorbing ink on a special metallic surface. The first two optical mice, first demonstrated by two independent inventors in December 1980, had different basic designs:

you could put code there that puts the cars back in starting position to start a new race.An early Xerox optical mouse chip, before the development of the inverted packaging design of Williams and Cherry At the bottom i put a little something that resets the boolean if the mouse is clicked. Setting the bool to true if distance is smaller than 60 and then, at the top of the draw-loop calling gameOver() if the boolean is true and returning afterwards (which causes the draw-loop to end executing there and not running all of the below game-code). Solved your question by introducing a boolean to keep track of gameOver-state. Hi, I took the liberty of cleaning up your code a little bit.

If the GameOver screen comes up and then if you move the mouse it goes back into the game because of the mouseX. I'm doing the GameOver Screen of my game and I ran into a problem.
