Important Pure Functional Optimization

Previously, due to my lack of imagination, looking up entities required 3 map look-ups. With the new optimization, only a single look-up is needed, enhancing Nu's baseline performance and scalability significantly.

And that's about it for this release!

Changes in detail -

Using Vmap in Effect. 6dd85cb
Important and significant optimization of Entity updates. a7b29e9

Upgrade to F# 4.0 / .NET 4.6, optimized scalability with persistent hash maps.

Some breaking changes, but likely none any end-user will notice.

Most importantly, (==) was changed from meaning reference equality to just a faster version of equality. If you use this, update your usage appropriately!

Now using a Name type to represent simulant names.

Addresses now use Names rather than NameKeys or strings.

Refactored to using pure ADT-style in Nu.

This is mostly done for my own agenda of fulfilling my thesis of using abstract data types to build sophisticated software.

This release was for me; you'll find nothing interesting in the change list unless you're a maintainer.

Added ability to disable RigidBody facet physics.

An oversight on my part not having done this earlier!

Several bug fixes and MountFacet.

Also includes Relation type that enables relative Addressing.

Effect system is still a WIP.

Changes -

Engine refactoring for additional efficiency and flexibility.

The main breaking changes here is the replacement of the GetRenderDescriptors EntityDispatcher signature with Actualize. Additionally, you may prefer to subscribe to local Update events for simulants now using the syntax (Events.Update ->- entity).

This release paves the way for implement an advanced effects / animation / movie authoring system in Nu, so please pardon the dust!

Additionally, there were some very important bug fixes.

Data format change and Critical Fixes

So, as it turned out my little sexpr syntax used for value notation Nu's serialization format was not usable beyond its intended purpose. That was fine, until it wasn't.

Since I found out it's just going to be too difficult to write an importer for an existing animation package, and not likely very usable, I decided to use said syntax to enable encoding effects in the upcoming Effect system.

What I found out very quickly, however, was that the syntax was too hard to use for this purpose.

So rather than adding an additional syntax (and make everyone's lives worse forever), I decided to fix up the existing syntax. So now instead of specifying a collision expression like this -

[PolygonShape | [0, 0 | 5, 5 | 0, 5] | 0, 0]]

we do the following -

[BodyPolygon [[0 0] [5 5] [0 5]] [0 0]]

• which removes the | that are, in most cases, lexically redundant.

Also, you'll notice that the name of the physic body shape types have changed.

So, if you've got a lot of data, you're going to have to convert it in order to get it to work with the new system. Fortunately, the conversion process is straight-forward. But because this is a data-breaking change, I've ticked the minor version number.

Additionally, there were some critical bug fixes.

Here are the changes in detail -

Added purer reactive programming model with OptSpecialization field.

To enable purer Petricek-style programming with Nu, I needed to add a field called OptSpecialization. This allows simulants (other than Game) to be specialized a step further than what's specified by the dispatcher type. Unfortunately, this implies rather a few breaking changes in the simulant creation functions. When you update your calls, make ABSOLUTELY SURE the parameters are in the order they're supposed to be, as there has also been some shuffling of them.

Here are the changes in detail -

Moved Prime operators to their own file. 4d3f631
Changed API of nearly all Simulant creation functions. BREAKING CHANGES 4d3c164

Small API clean up.

Haven't really done much but cleaned up the API a bit. This version sees the removal of the Nu.init () function from the public API since it's now called by the engine automatically.

Also, in an effort to support the best value semantics for Nu's World type, there is now a World.empty value that can be built upon. Not a useful detail for most users, but helps to keep the engine's design on a lofty track.

Gave more value-style semantics to World. Removed Nu.init () BREAKING CHANGE 0d9a936
More work on making World a value. b2dcda9
