walls.onEnterFrame = function() {  
with (\_root.circle) {  
if (Key.isDown(Key.DOWN)) {  
\_y += 1;  
}  
if (Key.isDown(Key.UP)) {  
\_y -= 1;  
}  
if (Key.isDown(Key.LEFT)) {  
\_x -= 1;  
}  
if (Key.isDown(Key.RIGHT)) {  
\_x += 1;  
}  
if (this.hitTest(getBounds(\_root).xMax, \_y, true)) {  
\_x -= 1;  
}  
if (this.hitTest(getBounds(\_root).xMin, \_y, true)) {  
\_x += 1;  
}  
if (this.hitTest(\_x, getBounds(\_root).yMax, true)) {  
\_y -= 1;  
}  
if (this.hitTest(\_x, getBounds(\_root).yMin, true)) {  
\_y += 1;  
}  
}  
};

Can anyone explain to me how that all works exactly? Like the !\_root. and the stand-alone \_y, \_x, and \_root? And if you feel empowered try giving the getBounds explanation a shot please.  
I want to break free :jailbreak of my current stupidity on this subject and not stay in my stupid cage :jail:
