Please back up your project in a separate directory before upgrading! You will likely need to reference the pre-upgraded project during the upgrade process.
You will likely need to recreate your bootstrap, as the authoring paradigm has completely changed.
Scene Manager now forces subscenes to load synchronously, and
DontDestroyOnSceneChangeTag will now protect entities from being destroyed by
subscene unload.
This changed a bit. If you were relying on specific ordering, you might encounter a few issues. However, such issues aren’t expected to be common.
With the transition from conversion to baking, Smart Blobbers had to be completely redesigned. The new design has a steeper learning curve, but is much more flexible. In 0.5.x, there was a 1-1-1-1 correspondence between the blob type, the input type, the converter type, and the conversion system. In 0.6.x, no such correspondence exists. You can define multiple inputs for a single blob type, and have multiple baking systems work with a blob type, or make a single baking system work with multiple blob types. The new paradigm uses bakers to add input components to special baking-only entities, and then uses baking systems to compute blob assets for those entities by writing to a special component. Blob asset allocation, deduplication, and incremental tracking are handled in separate baking systems, rather than a base class.
There is also a SmartBaker type, which serves to functionally replace
IRequestBlobAssets.
Make sure to add ENABLE_TRANSFORM_V1 to your scripting defines.
Not only is there a rename, but AssociatedComponentType expects a
ComponentType now.
These have been redesigned to be fully Burst-compatible in ISystem. While the
general concept remains the same, expect breakages in many of the methods and
interfaces. In particular, it is now up to the user to track whether a
collection component is initialized.
Execute() now receives its argument as an in parameter.
Multiple colliders on a single Game Object are supported (excluding convex meshes) and will be combined into a compound collider. The enabled checkbox will exclude the component from being baked.
This type now uses a context object passed by ref rather than protected member
methods. There is a new alternative way to specify a builder using
IListenerProfileBuilder if you need to construct a profile on the fly.
Several options for defining your own custom skeleton have been removed. Some features may be added back later. Also, the skeleton definitions have been tweaked to remove unwanted bones more aggressively. A skeleton parented to a bone in another skeleton should now be possible.
There is no longer a Smart Blobber for this blob type. If you need this, please reach out to me, as I am trying to better understand use cases to design a new effective API.
Collection Components and SyncPointPlaybackSystem and a whole bunch of other
goodies are Burst-compatible thanks to the new LatiosWorldUnmanaged type.
Also, try out the new ICustomBakingBootstrap and ICustomEditorBootstrap.
There’s a new FindObjects algorithm which works like FindPairs, but for a single AABB query against a layer. It runs faster than O(n) time.
There are now new shortcut APIs for raycasting, collider-casting, and distance-testing a layer. They all make use of the new FindObjects algorithm under-the-hood.
FindPairsResult has been overhauled to provide shorter syntax for distance
queries, and expose the layers for additional FindObjects queries.
Myri has a new API for procedurally generating audio at bake time for an
AudioClipBlob without the use of an AudioClip asset. The new API lets you
generate the samples in parallel Burst-compiled jobs.
You can bake a Skinned Mesh Renderer with dynamic skeleton binding info without
baking its parent skeleton. To do this, inside a baker, call
GetComponentsInChildren<SkinnedMeshRenderer>() and then call GetEntity() on
one of the results. I want to see someone do character customization with this!
