//3e. Center the bitmap so that its mid point is 0,0 matrix.translate(-_radius, -_radius); //3f. Rotate the bitmap 280 degrees (the value of _rotation) matrix.rotate(_rotation * Math.PI / 180); //4.

Add a bevel and drop shadow filter to the planet var planetFilters:Array = new Array(); planetFilters = planetShape.filters; planetFilters.push ( new BevelFilter ( 4, 135, 0xFFFFFF, 0.50, 0x000000, 0.50, 4, 4 ) ); planetFilters.push(new DropShadowFilter(4, 135, 0x000000, 0.35, 4, 4)); planetShape.filters = planetFilters; } As you can see, it s a lot of code, but you do have very fine control over how the image is displayed.

The magnitude (m) of a vector tells you how long the vector is. It s the distance between point A and point B. m = Math.sqrt(vx * vx + vy * vy); This is formula is the Pythagorean theorem.

Left and right normals
Normals are vectors that are exactly perpendicular (at 90 degrees) to the main vector. Find the left normal (lx) like this: lx = vy; ly = -vx; Find the right normal (rx) like this: rx = -vy; ry = vx; The left and right normals start at the base of the main vector and extend outward. That means that their start points (point A) will always be the same as the main vector s start point. You can find their point B coordinates like this: leftNormal.b.x = v1.a.x + lx; leftNormal.b.y = v1.a.y + ly; rightNormal.b.x = v1.a.x + rx; rightNormal.b.y = v1.a.y + ry;
Normalized vectors (unit vectors)
Unit vectors are the smallest size that a vector can be, while still retaining the vector s direction. Normalized unit vectors are represented by the variable names dx and dy. Find them like this: dx = vx / m; dy = vy / m;

Scaling vectors
If you have a unit vector, you can scale it to any size. Multiply the dx and dy values by any amount. scaledVector_Vx = dx * multiplier; scaledVector_Vy = dy * multiplier;
Gravity
To create a gravity effect between a spaceship and a round planet, follow this procedure:
1. Create a vector between the ship and the planet with values that are updated each
frame. shipToPlanet_Vx = planet.x spaceShip.x; shipToPlanet_Vy = planet.y spaceShip.y;
2. Find its unit vector.
m = Math.sqrt ( shipToPlanet_Vx * shipToPlanet_Vx + shipToPlanet_Vy * shipToPlanet_Vy ); shipToPlanet_Dx = shipToPlanet_Vx / m; shipToPlanet_Dy = shipToPlanet_Vy / m;
3. Create a gravity vector by scaling the ship-to-planet vector with a small number, like 0.1.
gravity_Vx = shipToPlanet_Dx * 0.1; gravity_Vy = shipToPlanet_Dy * 0.1;
4. Assign the gravity vector to the ship s vx and vy velocity values.
spaceShip.vx += gravity_Vx; spaceShip.vy += gravity_Vy;
5. For gravity that weakens as the objects move farther apart, add mass to the equation.
planetMass = 5; shipMass = 1; gravity_Vx = shipToPlanet_Dx * (planetMass * shipMass) / m; gravity_Vy = shipToPlanet_Dy * (planetMass * shipMass) / m;
Dot product
The dot product tells you whether vectors are pointing in the same direction. dp = v1.vx * v2.dx + v1.vy * v2.dy; If the dot product is positive, the vectors point in the same direction. If it s negative, they point in opposite directions.
Projection
A vector s projection is the shadow of the vector on another vector. The projection is itself a new vector. First, find the dot product of the vector you want to project (v1) and the vector that will be the surface for the projection (v2). dp = v1.vx * v2.dx + v1.vy * v2.dy; Next, multiply the dot product by the surface vector s (v2 s) dx and dy values. projection_Vx = dotProduct * projection_Vy = dotProduct * v2.dx; v2.dy;
