Some things to note:
Netty is screwy so currently can't join single player. @cpw
Crafting has been MAJORY reworked. The current GameRegistry functions are nooped, this is IN THE WORKS.
Just need to move the recipe list to a full class registry, and then re implement the in-code recipe registration.
Also, it IS advised that modders move to JSON, because ideally we'll see a S->C recipe syncing system in 1.13
which would allow servers to have custom recipes.
OreDictionary currently 1/2 works, need to write a better algorithm for replacing ingredients.
Please be patient
Rendering:
A lot of functions got a new float parameter, this is similar to partial ticks, needs more research
Major things to note:
Class renames: https://gist.github.com/LexManos/44dd211f90f498ad4015279b103dff86
Tile Entities are now packed in the ChunkData packet.
Forge intends to work around this to better support large moded worlds, but for the time being modders should implement the new function carefully and only send what data they need to!
Minecraft's codebase now has annotations, these are directly from Mojang and should be adheared to!
Added support for package-info.java's containing @Nullable information for all MC code base.
Added detection of mods that rely on Java 8 and a graceful error screen.
The nag screen will be shown once a day. It can be disabled by editing the forge.cfg.
However it is HIGHLY recomended that user update to Java 8.
Enables mods to modify raw FOV directly.
Avoids modifier limit from FOVUpdateEvent.
Aware of blocks which are needed for fov change related with materials.
Main things of interest:
* IAnimationStateMachine - state machine for animations; can load
from json.
* AnimationTESR - automatic TESR for animated models.
* AnimationModelBase - same for entities.
* ITimeValue - time-varying value, used to control animation
parameters from code.
* TESRs can now be batched - look at TESR.renderTileEntityFast +
TE.hasFastRenderer.
* RegionRenderCache is not accessible to TESRs and other client-side
logic - MinecraftForgeClient.getRegionRenderCache.
Changes to the Model API - IModelState now works with Optional. Handling of parts of the model is not optional, and coordinate space/result interpretation is up to the caller. IModel doesn't extend IModelPart by default anymore; MapModelState uses composition to achieve previous functionality, IModelPart implementations are disjoint now. Updated perspective handing to the new API, removed IPerspectiveState (MapModelState is now the same thing). Perspective transforms for the default fluid model.
