slice example via svn didn't work properly

What steps will reproduce the problem?
1. open 
http://quickb2.googlecode.com/svn/trunk/examples/qb2DemoReel/bin/qb2DemoReel.swf
2. try slice some object
3. that's it

What is the expected output? What do you see instead?
sliced object disappear, nothing falling

What version of the product are you using? On what operating system?
Win764x ie9 FP11.0.1.129

Please provide any additional information below.
from my test old example working fine
http://quickb2.dougkoellmer.com/bin/qb2DemoReel.swf

but last version 
http://quickb2.googlecode.com/svn/trunk/examples/qb2DemoReel/bin/qb2DemoReel.swf

just didn't work, i do saw some code change eg. import 
surrender.srVectorGraphics2d;

didn't digging more yet, just trying ;)

Weird collision behavior

Got this weird qb2ContactEvent results:

case #1 correct
added a tdSmartBody descendant to world in demo constructor
propelled it against another_body,
event.otherObject was another_body

case #2 weird
added a tdSmartBody descendant to world on keypress
propelled it against another_body,
event.otherObject was world
event.otherShape was properly a sshape within another_body

is it correct and i'm missing something?

Expose various queries from Box2D (raycasts, AABB, etc.)

This is mainly an API question, that is, how to expose these queries/callbacks 
intuitively using the flash events or some other means.

Please implement Ray Casting

Can't get Box2DAS.RayCast to work in QB2 world, don't really know why, so 
please make a QB2 Ray Cast as soon as possible.

Implement classes in QuickB2.stock.todo

These aren't really critical classes, but do show off very well how groups can

I simply never have and probably never will use these joints, but maybe someone 
else does and I should expose them.

Add a slice() function for all qb2Tangibles.

This function should take an amLine2d and literally slice whatever the object 
is in two.  Circle slices would be approximated by polygons.  This is pretty 
straightforward in most cases, but other cases (non-convex polygons for 
example) can get pretty hairy.  As can partial slices, where a line doesn't go 
all the way through.

Follow common naming conventions in AS3

This is a non-functional issue i stumble upon each time i re-visit your 
otherwise very good library.

Your packages begin with upper-case letters and you classes with lower-case 
letters.

I know you probably have other things on your mind, but it just looks soo 
awkward in the AS3 world.

Cache potentially performance intensive property getters like centerOfMass and bounding representations.

For now, if a user wants to repeatedly access something like centerOfMass for a 
really complicated qb2Group, the center of mass is recalculated for every call, 
when it could be cached and just invalidated the next step.

The workaround for now is to store the centerOfMass (or bounding rep) locally.  
This is best practice anyway due to function call overhead.

Protected methods instead of Private

Please change private methods to protected so one can extend them properly, ie. 
tried to extend qb2TripSensor but couldn't, and had to make a copy of it and 
modify the code in order to get it to do what I want. It would really help a 
lot.

Proof-read and add to manual.

Manual probably needs another good set of eyes on it.  There are also a few 
incomplete or missing sections.

Fix tweaked out springs.

Right now springs with really high springK can tweak out so that they never 
stop vibrating.  I'm thinking there must be some way to force a spring to stop 
if its frequency is past some threshold.  Any solution that fixes some springs 
might break others though, i.e. cause them to stop oscillating when they 
shouldn't.

Pull the Alchemy port of Box2D automagically from the git repository.

As it stands, updates to the Alchemy port of Box2D 
(https://github.com/jesses/wck/tree/master/Box2DAS/) have to be manually 
copy-pasted to QuickB2/dependencies/src, as opposed to the other dependencies 
which are pulled in with the SVN externals tag.

I'm not even sure if this is possible to do though.

How to use the WYSIWYG editor.

In the readme it says:
"Check in the examples folder to see how the whole system works with some other 
.flas."

In the examples folder I can't find any examples to explain how it works and I 
can't deduce how it works by the examples in the "qb2VisualEditorLibrary.fla" 
either. 

An example of how to create a level (for example) in the WYSIWYG editor would 
be great. Or some more documentation to better cover it.

Tire Friction

Hi dug :)

you use a single friction value for a tire. 
you should add a lateralFriction value.

so you may use "friction" for the torque force and "lateralFriction" for 
steering force.

so inside the carbody update you should have:

const tireFric:Number = tire.friction * frictionMultiplier;
var fricForce:Number = tireFric * tireLoad;

and also

const latTireFric:Number = tire.lateralFriction * frictionMultiplier;
var latFricForce:Number = latTireFric* tireLoad;


then you should change the lateral component of the tire speed

from:
    if ( force > fricForce)
    {
        tire._isSkidding = true;
        force = fricForce;
    }
to:
    if ( force > latFricForce)
    {
        tire._isSkidding = true;
        force = latFricForce;
    }


a wheel got a different friction, and generally the longitudinal << lateral.

Fix bound circle representations.

Right now bound circles are implemented (badly).  I want to use the fastest 
known algorithm for this, but it was kinda hard to implement so I never got 
around to it.

Implement Effects.

The API for effects (qb2Effect and subclasses) exists and is ready to go, but 
the classes have to actually be filled in.  This should be pretty 
straightforward.

TopDown: Lateral and Longitudinal Weight Transfer

Inside tdCarBody, when you compute the weight transfer you should clamp the 
final value.

Now:
var longTransfer:Number = vertDiff ? (zCenterOfMass / vertDiff) * totMass * 
_kinematics._longAccel : 0;
var latTransfer:Number  = horDiff  ? (zCenterOfMass / horDiff)  * totMass * 
_kinematics._latAccel  : 0;

Then you should add:
longTransfer = amUtils.constrain(longTransfer, -totMass, totMass);
latTransfer = amUtils.constrain(latTransfer, -totMass, totMass);

In this way you prevent that the car start to spin around itself, due to the 
wrong weight transfer.

Bug on TopDown CarBody code

Version: 2.0.6

File: tdCarBody.as
Line: from 286 to 302
Error type: copy/paste mistake

Actual version:

if ( !axle.numBot )
{
    axle.numBot = 1;
    axle.numBot = centroid.y - (axle.avgTop - centroid.y);
}

if ( !axle.numLeft )
{
    axle.numLeft = 1;
    axle.numLeft = centroid.x - (axle.avgRight - centroid.x);
}

if ( !axle.numRight )
{
    axle.numRight = 1;
    axle.numRight = centroid.x - (axle.avgLeft - centroid.x);
}

Corrected version:
if ( !axle.numBot )
{
    axle.numBot = 1;
    axle.avgBot= centroid.y - (axle.avgTop - centroid.y);
}

if ( !axle.numLeft )
{
    axle.numLeft = 1;
    axle.avgLeft= centroid.x - (axle.avgRight - centroid.x);
}

if ( !axle.numRight )
{
    axle.numRight = 1;
    axle.avgRight= centroid.x - (axle.avgLeft - centroid.x);
}

Implement frictionZ.

Right now the whole API is rigged up for frictionZ, but it doesn't actually do 
anything.  Implementing this will entail adding various applyForce() calls in 
qb2Body::update() and qb2Shape::update().

qb2_friend namespace access modifiers converted to public in .swc.

So if you're using the precompiled .swc for QuickB2, you get public access to 
all the behind-the-scenes stuff that is namespaced in order for "private" 
members of classes to be able to talk to each other (like the friend modifier 
in C++).  At best this horribly confuses the API, at worst it gives outside 
access to stuff that definitely should not be accessible.

Anyone know how to fix this???

Using quickb2 in Flash CS5.

I can't get CS5 to import the QuickB2.swc and when compiling from source files 
I get stuck on this:
"import cmodule.Box2D.*;" I can't find this cmodule thing.

An example or detailed instructions on how to use QuickB2 in flash cs5 would be 
great. (If it is even possible.)

Allow non-uniform stretching/skewing of circles in the visual editor.

Just like with the rectangle shape proxy, users working in a .fla should be 
able to mess with circles any way they like.  If the result is a non-circular 
shape, then it should be approximated with a polygon.

choppy movement

Hello, doug!

My car movement is very choppy, what could be the problem?
My code is slightly modified CarDriving class from example. 
I use this settings:

stage.frameRate = 61; //(100 results same result)

world.actor = addChild(new Sprite());
world.maximumRealtimeStep = 1.0 / 20.0;
world.gravity.y = 10;
world.start();

playerCar.mass = 1000;
playerCar.tractionControl = false;

Please, review my example in attachment or by this link 
http://hldm.ru/temp/car.swf.

Thank you for the engine!

Make component icons for core qb2Proxy subclasses.

This would just be a nice touch for those using the visual editor for FlashCSx. 
 If the icons clearly delineated what they represent, it could potentially 
increase work flow a lot too.

SWC not usable in FDT 4

What steps will reproduce the problem?
1.Create new project in FDT 4, or open an existing project.
2.Add QuickB2.swc to the classpath

What is the expected output? What do you see instead?

Expect SWC's contents to be browsable, and for code completion to recognise it. 
Instead, there appears to be nothing inside the SWC and FDT does not 
code-complete for any of qb2's classes.

What version of the product are you using? On what operating system?

qb2 v0.6
windows 7
fdt 4.3.1

Please provide any additional information below.

The same SWC does work in flashDevelope. (i will be sending the issue to FDT as 
well, i suspect it might have to do with being HaXe-compiled)

Have getLinearVelocityAtPnt-type functions be available when an object isn't in the world.

Right now these types of functions only work when the object is in the world, 
because the call is passed on to Box2D.  When an object isn't in the world, 
custom as3 code should handle the request.  Right now a zero-length vector is 
returned.

world.translateBy() slow

I'm creating online game where a 2D-cyclist is moving along a hand-drawn path 
(simplier version of canvasrider.com). I need to move whole world left/right so 
the cyclist remains centered. While moving world using world.translateBy()

(around 0-10fps). Is there some different way to move world with all of the 
objects inside it?

Notice: topDown Transmission

Version: 2.0.6

function: shiftToOptimalGear
line: 175

code:

var estimatedTireRotSpeed:Number = linearSpeed / _carBody.tires[0].metricRadius

you should use a driven tire. you are doing the assumption that all the tires 
has the same radius.
if I use a car with front wheel radius < rear wheel radius, and the rear wheels 
are the driven ones, that your code produce a wrong result.

(in any case, you should check if the carBody has at least 1 tire :) )
