the frictional force in a collision like this is what causes the change in angular velocity;
the angular velocity also effects the frictional force; and the frictional force will also incur a change in linear velocity.

I'm dividing by the mass since i described it as being the force that was proportional:

F = kf(x), so the acceleration would be a = k/mf(x)

Ofcourse, in the case of gravity; k would also be dependant on m and would work out as being being invariable with respect to m :P

your engine considers only the velocities of the objects, you need to modify it to handle acceleration aswell, if you cannot do that; then you need to go learn some basic physics first ;)

if you want to follow physical models of such things, then you will have a force of gravity that is inversely proportional to the distance between the centre of masses squared in the direction of the other body for all gravity wells or whatever it is you're calling them, and for air resistance, a force in direction opposite that of motion proportional to the velocity squared.

let dx,dy denote the vector from an object to a gravity well, the acceleration experianced is given by
ax = dx*dl;
ay = dy*dl;
where
dl = K/m*(dx*dx+dy*dy)^(-3/2)
and K is a constant and m is the mass of the object

let vx,vy denote the velocity vector of an object, the resistance to motion will be given by the acceleration
ax = vx*dl;
ay = vy*dl;
where
dl = -K/m*sqrt(vx*vx+vy*vy)
and K is a constant and m is the mass of the object

Note also that this is a general transformation into a 2d basis defined by R B and P.
In an isometric projection, it will degenerate: in this case Ry = By, and Rx = -Bx; but it doesn't matter since it is all calculated once for matrix values. Just to mention that R and B may be any vectors that are not colinear and this will still work :P

Basicly, you have your tile coordinate system (space) in which (0,0) refers to top left of tiles, and (x,y) refers to the top-left of the tile in the y'th row and x'th collumn

You then have the projected space which is the result of transforming the tile coordinate system so that it is in screen coordinates for rendering basicly.

You can see the two spaces in the flash, and how moving mouse around in the bottom right one displays the position in tile-space and vice-versa. The top left is moved and scaled so that it isn't super tiny as it would be if represented properly in screen space (Since without scaling and moving it, the tile-space image would only cover an 8x8pixel area at top left of screen)

Link to Flash

You can also see the two transformation matrices, T is the one that goes from tile space to projected space, and T^-1 is the other way round.

R refers to the value of the red vector in the projected space, and B the value of the blue vector in the projected space with P being the coordinate of the origin in projected space.

You can see how going from a position of (x,y) in tile space, gives you a position in the projected screen space of (P + xR + yB) and that is the basis of the transformations:

Letting the values of P R and B be represented as Px,Py Rx,Ry Bx,By the two transformations become the matrices

= [Rx Bx Px]
T = [Ry By Py]
= [0 0 1 ]

-1 [a b c]
T = [d e f]
= [0 0 1]

where you can calculate the values for T^-1 as:

var idet:Number = 1/(Rx*By-Bx*Ry);
var a:Number = By*idet;
var b:Number = -Bx*idet;
var c:Number = (Bx*Py-By*Px)*idet;
var d:Number = -Ry*idet;
var e:Number = Rx*idet;
var f:Number = (Ry*Px-Rx*Py)*idet;

and hence you're two transformations on the vector (x,y,1) as being

//From tile to projected
var x2:Number = Rx*x+Bx*y+Px;
var y2:Number = Ry*x+By*y+Py;

//From projected to tile
var x2:Number = a*x+b*y+c;
var y2:Number = d*x+e*y+f;

if you project mouse coordinate into tile space, and take the integer part; you will have the indices relating to which tile it is on: so if the coordinate of mouse in tile space is

(12.68,7.18) the tile it is over is in the 7th row, and 12th collumn

that system does not have 4 solutions, none of those 4 points you highlight are solutions; a solution to a system of linear equations is one in which all equations are satisfied, in your example there, for each of your proposed solutions only two out of 4 equations are satisfied.

it is IMPOSSIBLE for a system of linear equations to have anything other than zero, one or infinitely many solutions.

It is imposible for a system of linear equations to have anything other than a single solution, no solution or infinitely many solutions.

I don't not not concur.

For backface culling you needn't even have the normal or points translated to camera space, nevermind 2d space, it can be done all in world space.

Given a surface normal N and a point P (any point on the surface's plane even, needn't be on the surface itself!) and a camera position C, you have

(C-P).N > 0 (or conversely, (P-C).N < 0)

if that is satisfied, then it is front facing (0 is perpendincular and also excluded from front-face test since it would be redundant to render it) so really, after doing frustum culling, you then perform this front-face test, and if it is front-facing, proceed to transform into camera space and do whatever else you need to do to render it.

Which you aren't actually using at all.

You're code is kind of the equivalent of giving someone directions to town, and then simply tell them to go around a roundabout 100 times then stop.

I'm not going to tell you how to fix your code, because it is a horrible method of doing what you are intending; to iterate over clips in this manner, when generating the clips you should be storing them an array to be iterated over; it's much cleaner, better practice, and also runs faster.

I got a 3 on my first try of that colour thing :)

The only utilities flash provides for collision detection is bounding box intersection tests, and a point in graphic intersection test, you've encountered first; the second;

AS1/2 hitTest(x,y,true);
AS3 hitTestPoint(x,y,true);

the boolean states you want to test against the shape of the graphic as opposed to it's bounding box.

AS provides no alternative utilities for intersection tests; you need to build them yourself if you want anything more complex, if you want more information, ask; i can't be bothered to start ranting if it's to no end.
