1) How do I make a button or any sort of thing (MCs etc) activate (go to the next frame or wtv) by just touching it with the mouse, without needing to click it?

2) How do I make a button that activates when a movieclip touches it?

For example, a game where you are a person collecting an object using your arrow keys.. When the MC touches the button/MC/whatever it could be, the next scene/frame plays.

THANKS...
