1.21.4-v2.20.0

General Changes

• We're on 1.21.4. With that comes the general expected changes, like item data components.

Building Tool

• Clone: Now works across dimensions and players. You can hand another player a building tool and access their cloned region regardless of what dimension it's from.
• Added a nifty animation when the GUI opens :D

Gel Blocks

• Gel blocks have had their back end rewritten from scratch.
• Previously, Gel Blocks implemented the IStructureGel interface to hook into the various spreading mechanics, used an enum of behaviors to determine the default spreading rules, and had a block state for how far it traveld. Most of this is gone.
• Gel spreading behavior is now registered under structure_gel:gel_spread_behavior.
  • This is how gel spreads along a specific axis, or along diagonals.
• Gel spreading restrictions can be registered under structure_gel:gel_spread_restriction.
  • This is how blue gel knows not to spread into exposed areas, or how orange gel knows to stop based on the item stack count.
• The distance gel spreads is now an absolute distance to the initial source instead of traveling and counting how many were placed, and reaches a sphere shape if fully expanded.
  • This allows gel to spread more effectively in twisting hallways, and more reliably hit the corners of large rooms.
• Any block can be used as gel in a structure as long as it's added to the structure_gel:gel block tag. If the block in the tag is actually a StructureGelBlock, it can customize what it places instead of defaulting to air.

Data Handler

• Changed how registry works so that a builder is what gets registered. See implemented data handlers for reference.

Dynamic Spawner

• Changed how registry works so that a builder is what gets registered.

GelPortalBlock

• Completely rewritten. Hopefully for the last time. The GelPortalBlock class is abstract and requires the implementation of various methods to make the portal function properly (with similar behavior to a nether portal).
  • Ignition of the portal is handled by calling GelPortalBlock.tryIgnite.
  • The dimension transition screen must be registered manually.

Registries

• Added two new registries; structure_gel:gel_spread_behavior and structure_gel:gel_spread_restriction.
  • Used to control the behavior of Gel blocks. Custom values can be registered and implemented on your own custom Gel block.
• Changed the registry process of structure_gel:dynamic_spawner_type and structure_gel:data_handler_type.
  • The new registry approach instead works by registering a "factory" to create a Data Handler or Dynamic Spawner. Overall, the code is more builder-focused and simplified, with access to registry data to prepare for more registries moving to datapacks in vanilla.
  • See com.legacy.structure_gel.core.registry.SGRegistries for how to register the new data.

Registrar

• Internal changes to how data is stored. The basic rules of "don't get a value before it was registered" still applies.
• Registrar.Static now contains a Holder.Reference for the object registered.
• Registrar.Static can be created with a name only using RegistrarHandler.named(String).
  • In this case, a value must be assigned later through RegistrarHandler.addHandlerListener(Consumer<RegistrarHandler>).
  • An error will be thrown if a static registrar is created by name only and never assigned a value.
• Added updated handling for block and item registry.
• See com.legacy.structure_gel.core.registry.SGRegistries for usage.
