I'm making a small java 2d game and i have followed a tutorial for collision detection. yet after implementing it into my code nothing happens when the rectangles Bound1 and PlayerR collide. I've tried following the tutorial again yet still nothing happens. No errors show up.

Thanks in Advance

PlayerR's bounds get set once and never get updated. btw, Java variable names should be in camel case and begin lower case
