About this project
What does Sky Dimensions add?
SkyDimensions
A NeoForge 1.21.x addon mod for Skyblock Builder that separates the spawn island into its own dedicated dimension.
Compatible with Sky GUIs.
What It Does
In vanilla Skyblock Builder, the spawn island and player team islands all exist in the same overworld dimension. SkyDimensions changes this by:
- Registering a new void dimension (
skydimensions:spawn) using SB'sskyblockbuilder:noise_basedchunk generator - Redirecting SB's spawn location to this new dimension, so new/teamless players arrive on a spawn island in a separate world
- Keeping team islands in the overworld — when players create or join a team, SB places their island in the overworld as usual
- Applying safe-zone rules to the spawn dimension (no mobs, no damage, no hunger, etc)
Players use the same commands as always — /skyblock spawn, /skyblock home, /skyblock create, etc. If Sky GUIs is installed, using /sky gui opens the team GUI exactly as before. The only difference is that the spawn island is in its own clean dimension.
Dependencies
- Skyblock Builder (Required)
- LibX (Required)
- Sky GUIs (Compatible but not required)
Spawn Protection
Spawn protection is handled by Skyblock Builder's own config. Configure in config/skyblockbuilder/spawn.json5:
- Set
spawnProtectionRadiusto the number of chunks to protect (default0= no protection) - Customize
spawnProtectionEventsto control what is blocked (damage, block breaking, mob spawning, etc.)
SkyDimensions extends SB's protection to the spawn dimension automatically.
For Pack Developers
SkyDimensions is designed to work out of the box. The spawn dimension is fully customizable via datapacks. Override the dimension JSON and dimension type JSON in your pack's data/skydimensions/ folder. For reference on how this works Skyblock Builder Wiki
The spawn island template can be customized via Skyblock Builder as shown here
