I can get this vector stuff to work, going from moving a vector to making a vector bounce is a huge gap and I dont know how to get across.
Code:
// Declair Objects
Ball = {};
Wall = {};
// Balls First Point
Ball.p0 = {x:100, y:100};
// Wall First and Second Points
Wall.p0 = {x:380, y:120};
Wall.p1 = {x:380, y:200};
// Direction Components
Ball.vx = 1;
Ball.vy = 0;
Wall.vx = Wall.p1.x-Wall.p0.x;
Wall.vy = Wall.p1.y-Wall.p0.y;
// Main Function
onEnterFrame = function () {
	// Move the MC MainBall to the current Ball vector
	MainBall._x = Ball.p0.x;
	MainBall._y = Ball.p0.y;
	// Calculate the end point using the Direction Components
	Ball.p1 = {};
	Ball.p1.x = Ball.p0.x+Ball.vx;
	Ball.p1.y = Ball.p0.y+Ball.vy;
	// Make the first vector equal to the second vector
	Ball.p0 = Ball.p1;
	// Left Hand Norma of Wall
	Wall.lx = Wall.vy;
	Wall.ly = -Wall.vx;
	// Dot Producted Between ball and wall
	dp1 = Ball.vx*Wall.vx+Ball.vy*Wall.vy;
	// projection of movement vector on the v2:
	proj1.vx = dp1*Wall.dx;
	proj1.vy = dp1*Wall.dy;
	//reversing projection on the normal:
	proj2.vx *= -1;
	proj2.vy *= -1;
	//finding new movement vector by adding up projections:
	Ball.vx = proj1.vx+proj2.vx;
	Ball.vy = proj1.vy+proj2.vy;
       // The rest of the code just changes the direction componeants
       // and resets the vector to the oposite side if it goes out of the stage.
}
That is what i have, i have been trying to follow tony's tute's, the first bit is heeps easy to follow wen well writting, but the whole bonce thing i dont get, it explains everything and how it works but I dont understand how the code does what it does. I downloaded the souce and its nothing like the stuff on his site so i found no use to it at all, is the code on his site just to show how stuff works and not actualy making the ball bounce?

Can some one have a look over my code and tell me what I have done and what needs to be done.

The italic code is the most recent stuff i added, once i added it my vector no longer moves.

Cheers
