Fix a.. well I guess bug in Body::copy() in that angular velocities, and also kinematic/surface velocities were not copied over as well.

Also an internal change which should see a 5mb memory usage decrease in all cases where a Space is used, and a further 5mb memory usage decrease whenever that Space happens to use the default DYNAMIC_AABB_TREE broadphase type. In testing with the pyramid stress test, fps has not been affected by these changes.

Also a new demo DynamicDestruction

Fixed a 'crazy' memory bug, which in for example the stress pyramid demo would cause +1mb/s increases in memory usage (eventually reclaimed by GC, but still crazy considering nape at this point is not allocating any memory at all)

The cause of the bug, was a hack I was using to get around an old haxe bug to do with Math.POSITIVE_INFINITY not mapping correctly when nape was compiled to a .swc and I got aruond it use the rather hacky: cast(untyped __global__["Number"].POSITIVE_INFINITY, Float) which works perfectly fine and should be mapped by haxe at compile time into the same thing as Number.POSITIVE_INFINITY would be in as3... and yet for some reason was causing the CRAZY memory usage when being accesses thousands of times per frame.

Anyways, the haxe bug it seems has been resolved since so i could go back to native infinity, and all is well now with stress pyramid demo showing a very flat memory usage graph.

m8.1

To abide by GPL strictness, convex_decomposition and monotone_decomposition algorithms and related internal algorithms are removed from nape.

Until I can produce replacements, the demos using these algorithms have also been removed and I ask that no-one uses older versions of nape (or atleast not with a public-release unless they wish to open source their work). *SIGH* Sad

Licenses are being added to all old versions of nape using the derivatives of CGAL.

8.2

Monotone, Convex (and also Triangular) decompositions re-introduced into nape, no more ties to CGAL and their GPL licensing. phew.

Also fixed a minor bug with Body::graphic with respect to assigning non flash displayobjects, and to do with graphicUpdate being in general, called twice per-step rather than once.

Also fixed a minor bug in GeomPoly::clear.

Also all demoes using the convex decompositions are back online again and functioning.

Should see another 10mb (roughly) memory decrease at runtime now, and also removed a non-critical assertion from the innards of the Dynamic AABB broadphase which won't really effect people except for using the assert builds, or having slightly less computation when it does occur in the debug/release builds (which to this point would have ignored the assertion and carried on doing nothing but duplicate work in this instance).

Big changes!

After a lot of work removing all inlining from nape, then optimising re-adding inlining until performance was comparable with before. We now have much smaller binary sizes, and also much faster iOS export times from AS3.

m9.1

Version change is related more to the new way in which nape libs are released/downloaded than actual changes to features.

Now, you will notice that when downloading nape libs (AS3 libs) that there are drop-down boxes to select what version + revision + build you want and a download button. I've also removed the haxe lib options, since using haxelib is just 'easier', if anyone really wants to use -swf-lib still they can unzip the .swc as you normally would.

What actually happens now with the downloads is that the build is compiled+cached on the server side, not on my computer anymore Razz

----------

Fixed issue to do with type-checking of Vector<Vec2> in such places as Polygon constructor so that it should work now Razz

Not bothered with a haxelib release as haxe users have no changes.

For AS3 iOS users, i've included a workaround for adobe's iOS bug which seems to be working in testing; please test as well and check if it's working now.

For the curious the workaround consists of:

static var log:Bool; //<---
static function theeffectedfunction(..) {
   ...
   log = ret; //<---
   return ret;
}

hahahahahaha.

I've added a fairly long (yet extremely brief to what can really be said to cover 'everything' in detail) overfiew of nape's core functionality to the documentation:

http://deltaluca.me.uk/docnew/docs/Overview.html

The only thing not covered at all are the geometric utilities.

Remove debug views from non-flash/nme builds.

Add Vec3.get(...) and Vec3::dispose() for object pooling alla Vec2's which are used internally in all cases now so that impulse query methods won't explode with object allocations Smile

For those of you that are interested, I direct you to a new nape module which is stable, but could be extended (hint, hint those that are saavy) to be more optimised and general purpose. https://github.com/deltaluca/nape-symbolic which comes together with a new download target (HaXe externs) which can be used to generate an AS3 .swc for this module which will link with nape at load-time meaning it can be a very small .swc

A few minor changes made internally which should not have effected anything, changes needed to allow creation of new module.

nape-hacks

New module providing stable, but technically hacky features to nape; at present forced-sleeping of objects, and ability to add already sleeping objects to a space.

For example check https://github.com/deltaluca/nape-hacks/tree/master/test

nape-symbolic

Updated (from haxelib will have to remove, then install as i've not done a new version) to change package name to nape.symbolic

----------------------------------

Changes have been made on the server for downloads with modules now available for on-demand compilation and download with the most suitable version of the specific module chosen with respect to the selected nape version with only available modules for a version listed Smile

Hopefully there's no bugs there, let me know if there's any problem with the download menu.

Hopefully I can also work on getting documentatino for the modules along side nape's documentation as well as demos.

Consider this a rare update during my exam period ;p

Polygon::localCOM is now mutable, and added Space::interactionType : Shape->Shape->InteractionType to determine what interaction type would be computed between the two given shapes (check doc for full description). Docs also updated w.r.t methods like shapesInBody on Space to clarify the purely geometric use of the input Shape/Body in the functions.

)

# Fixed small bug in Polygon, wherein should the first vertex be a collinear vertex it was previously not being culled.
# Fixed small bug in Vec2::rotate() not invlidating the structure (reported symptom being Ray directino not able to be rotated).
# Fixed lots of typos in Documentation
# Added Body::interactingBodies : ?InteractionType -> BodyList to gather all bodies interacting with 'this' body for the given interactino type.
# Added Body::connectedBodies : BodyList to gather all bodies 'connected' to the body by constraints that are part of the space.
# Modified Body::constraints so that it tracks all constraints in space linked to body, not just active ones.
# Added Body::graphicOffset : Vec2 and Body::graphicAngleOffset : Float to facilitate offset-graphics without needing to use graphicUpdate.

Milestone 10.1

!!! BREAKING CHANGES !!!

Milestone 10.1 introduces big changes to the callback system, massively increasing it's expressiveness and modularity.

Note that these changes break backwards compatibility with Milestone 9.1

API documentation and Overview doc file have been updated, as well as demos and for PhysicsEditor users, I've passed updated plugins to the author so I would expect them to be available shortly.

I have tested these new extensions a lot, but it is possible there may still be some issues that I have not found so 'please' test and post a message on the forum if you find something that you think may be a bug!

-------------

Quick overview of changes made:

Instead of having a single CbType on an object, there is now a list of CbTypes on objects; think of this as being akin to implementing multiple interfaces in AS3/Haxe.

Instead of a listener taking a CbType (or for interactions; pairs of CbTypes) listeners will now take what is called an OptionType which represents two lists of CbTypes - an includes list, and an excludes list - such that a given object's cbTypes list will match against the option if it shares an element with the includes list, but does not share an element with the excludes list.

Additionally the restriction that in any given instance there must be only one choice of listener has been removed, and an additional property added to listeners as an integer precedence value (default to 0) which induces an ordering when there are multiple valid listeners.

Additionally all objects now receive a default CbType in their cbTypes list. For Body's this is CbType.ANY_BODY, similarly for Shape,Compound,Constraint. In this way, we can take a listener to act on 'any' Body, by having CbType.ANY_BODY in the includes list of the OptionType. We can also have a listener act on 'any' Body 'except for' a given type of Body by decorating those special bodies with another CbType, and including that CbType in the excludes list of the OptionType.

Listener constructors take a dynamic value, which is either a CbType, list of CbType's or an OptionType so that these two examples could be done like:

new BodyListener(CbEvent.SLEEP, CbType.ANY_BODY, ...);
new BodyListener(CbEvent.SLEEP, CbType.ANY_BODY.except(otherCbTypes), ...);

Check API docs for more information regarding OptionType and new methods on CbType's.

Minor non-critical bug fixed (only manifestde itself in an assertion on assert builds, with silent, non-optimal (but coherent) behavour in debug/release) To do with removing objects making use of callbacks when listeners exist between pairs of equal callback sets.

Fixed a more major bug which has actually existed for a long time, and would previously have resulted in some silent (but coherent) errors, and with new callback system manifested in critical errors. To do with waking a sleeping object outside of space.step() (aka, changing position, velocity etc) when such an action would cause an end to an interaction which previously would have gone uncaught.

(More loss of backwards compatability (minor))

CbType/OptionType exclude/include methods changed to 'excluding' and 'including' due to problems in AS3 with include being a keyword.

Fixed small bug that Listener::event would be (on getter) returning null if event was CbEvent.ONGOING

Fixed small internal assertbuilt-only non-critical bug in removing objects with cb types Wink

Some minor (breaking) changes to GeomPoly in return types/values of various methods like push/pop/erase to return the 'this' GeomPoly for chainable operations.

Mat23::inverse_transform changed to Mat23::inverseTransform (fits rest of API better).

Mat23.scale(sx, sy) now has sy no longer optional. Two reasons:
It was assumed that the default value would be NaN, but this is only true for flash.
With changes to be made in Haxe 3.0, marking sy as optional without a default value
would make it be boxed as an object (with default null) which would not be wanted.

Not a big change really Razz

Simple internal change fixes bug with sharing CbTypes amongst multiple concurrent Spaces
if that is the sort of thing you want to do mr LongAnimals.

Simplex fix for Vec2.weak/get to correctly reset internal immutable field, thanks gypsy!

Started transitioning for Haxe v3, removing ? decorations from types where no longer
appropriate.

Bug fix in triangular and convex decomposition routines.

Effected the (breaking) change for userData.
For those that did not read the proposal userData has been changed from a field of type Dynamic (* in AS3) that you can assign any value to, into a lazily constructed object of type Dynamic<Dynamic> (Also * in AS3), which you cannot assign to directly, but instead create a named field of meaning that as long as you use unique names, you essentially have infinite userData fields now.

// before
obj.userData = x;
trace(obj.userData);

// now
obj.userData.x = x;
trace(obj.userData.x);
obj.userData = x; //ERROR

As a general update on development; I'm spending time at present on a private branch moving all of nape documentation into inline documentation in the code so that Haxe users will when finished immediately get code hints with documentation in IDE's. I will also be changing the online documentation to a form generated via the inline code docs and will be looking into how best to compile asdoc .xml's that can be embedded in the AS3 .swcs so that AS3 users can also benefit from this change.

I apologise for the number of breaking changes (however little) that have occured recently! Whilst adding these inline code docs I have found some more places where i will be breaking compatability in future (only name changes so far so that camelCase is used consistently instead of a mix of camelCase and camel_case)

r7... again (For some reason it overwrote the previous r7.. not sure why but nevermind)

# Some minor bug fixes.
(SweepAndPrune broadphase + empty space queries)
(Internal minor fixes)

# Work-around for adobe-iOS exporter bugs affecting ongoing callbacks (thanks dmeville)

# Optimisation for BitmapDebug:
If you are using BitmapDebug 'as well as' another library that makes use of Alchemy memory, then you should now call BitmapDebug::prepare() before performing sets of actions that use the bitmap debug object in anyway to switch the alchemy context to the bitmap debug object. (Before every operation switched the context, but seems flash has no short-cut for checking that the context you switch to is not already the current context and was using some crazy cpu from profiler).

# Simple internal optimisation for the additional logic that sits beside colisino detectino phase.

# Fix bug in GeomPoly::cut()

# Fix bug in removing all vertices from a Polygon, and in accessing the vertices of a polygon in a particular manner when
there are collinear vertices (which are removed automatically).

'very' minor update to the present version to solve an AS3 issue with nape-hacks being broken for most recent versions.

No change has occured for haxe users and no haxelib release was made.
