Vertical Slabs Everywhere
by jrh
Vertical Slabs Everywhere gives every slab that other installed mods register a vertical variant, using the same mechanism as Quark's vertical slabs.
What it does
Installed mods that register wood, stone and brick slabs each receive a matching vertical slab. The mod scans the block registry at load time and creates a vertical variant for each slab that has no counterpart yet, so it fills only the gaps the other mods leave. Vanilla slabs are skipped because Quark already covers them, and a check against the actual vanilla block list keeps them out of the scan.
Vertical variants inherit their models from a parent and get display names that follow Quark's naming convention. Blockstates and models are generated at runtime, and loot tables double drops. Two crafting recipes convert a slab into a vertical slab and back, and a per-mod configuration file controls which slab families receive a vertical variant. Moonlight Lib is used for the late-registration hook, the same mechanism the Vertical Slabs Compat mod uses for the whole modded registry.
Installation needs NeoForge for 1.21.1, Moonlight Lib, Quark and Zeta. The mod is released under the MIT License and is open source. Every player and the server need a copy of the mod.
Key features
Automatic vertical slabs
Each slab registered by another installed mod gains a vertical variant at load time, with no manual setup.
Gap filling
Blocks already provided by another mod are not duplicated, so only missing vertical slabs are added.
Per-mod configuration
Each source mod can be enabled or disabled individually, with a setting for whether crafting recipes are added.
Vanilla slab handling
Genuine vanilla slabs are skipped, since Quark already provides their vertical versions.
