Skyblock is an unofficial game mode for Minecraft that was established in 2011. It was originally a challenge map that contained a single tree, a chest with supplies, and a small cube of dirt, and the player was expected to survive using the resources they had and their knowledge of the game.

Now, Skyblock is one of the most popular game modes (following Survival and Creative), spawning thousands of different varieties and twists to pull in new players and sell the idea of a challenge that can be enjoyed with friends.

IridiumSkyblock, as with all of Iridium Development's software, aims to deliver a premium image, streamlining the setup process and eliminating the headache of having to figure out the details, while also proving to be extremely configurable to create an unparalleled experience.

Every aspect of the plugin has been carefully crafted to suit the server's needs, and between the extensive GUI customization and plethora of extra options, server owners can rest easy knowing that there's a Skyblock plugin out there that fits their needs. It's this one, if you were wondering.

Features

  • An easy to use GUI, fully customizable and ready for players the moment you install the plugin.
  • A server shop that's easy to use and configure, has both buy and sell features, and allows you to run commands on purchase.
  • A mission system with tiered missions and mission tracking that updates automatically.
  • A bank system that supports multiple different currencies, and EXP storage.
  • A scoreboard that ranks available islands by either island experience or block value.
  • Team-based cooperative play, complete with permission management and a shared bank for all players of the same island.
  • Enhancements that make gameplay more interesting; between boosters for temporary improvements to help with specific tasks and upgrades that give fun advantages, players will become and remain engaged.
  • A border around every island, and the color can be customized by the player.
  • Islands generate in all three dimensions, complete with their own schematics, can be configured.
  • SQLite support.

> - Fixed the Trusts GUI to correctly display trusts.
> - Fixed an issue where the plugin would crash violently when reloading the config.
> - Added deserialization to the config, allowing all recognized XMaterial names for items.

> - Fixed an issue where offline players would not have their inventory wiped on island delete / regen.
> - Added spawnOnIsland to have players respawn on their islands.
> - Added INTERACT permission to fix item frames and signs not being protected by permissions.
> - Re-implemented the ability for players to click with Island Crystals to deposit them into the bank.
> - Fixed the flight enhancement staying enabled outside the player's island.
> - Added a check for if the player is in a gamemode that allows flight natively.

### *Translation*

### *Placeholders*

> - /is cleardata <table> (team) (--skip-confirm) - allows administrators to clear specific data from the database without having to maually edit the tables (which can be dangerous). Has a confirmation dialogue that can and will be skipped when not run as a player. **DESTRUCTIVE**.
> - Updated Commands:
> - /is info (--get-location) - added an arugment to get info for the island at your location.
> - /is bank & /is experience can now be run from the console.

### *Support*

> - In order for the terrain generators to work with island regen, a copy of each IridiumSkyblock world is saved in IridiumSkyblock/regenWorlds and they are loaded at runtime.
> - Configuration files are now less finicky, and will attempt to fix themselves before wiping.
> - Fixed an issue where an invalid configuration may result in a stack overflow error and disable the plugin.

### *Code*

> - Added getIslandViaPlayer(Player) API method.
> - Created SupportManager to manage supporting classes, which includes StackerSupport, SpawnerSupport, and SpawnSupport interfaces.

# Beta Information

## Known issues

> - The world generator does not load correctly on versions 1.13 - 1.16.5. This is because we use the shouldGenerateDecorations() method that was introduced in Spigot's 1.17 world generation API update. There are plans to address this.
> - /is cleardata will likely produce SQL errors - this does not appear to be an issue with the command itself, nor affect functionality.

### Since 4.1.0 BETA 4

> - 1.20.6 support
> - 1.21.4 support
> - /is cleardata <table> (team) (--skip-confirm)` - allows administrators to clear specific data from the database without having to maually edit the tables (which can be dangerous). Has a confirmation dialogue that can and will be skipped when not run as a player. **DESTRUCTIVE**.
> - Updated shadow plugin to fork.
> - Updated XSeries methods.
> - Fixed placeholder rounding issues.
> - Added database locking (prevents race conditions).
> - Fixed swapped placeholders.
> - Fixed an issue where the plugin would incorrectly report an invalid generator type.
> - Fixed an issue where the plugin was not tracking Y movement.
> - Fixed an issue where the plugin was tracking Z more than X coordinate movement.
> - Configuration files are now less finicky, and will attempt to fix themselves before re-loading the default.
> - Fixed an issue where an invalid configuration may result in a stack overflow error and disable the plugin.

## Known Issues
  • Stacked blocks and spawners are acting a lil strange, but they're mostly sorted out. If it takes more than five minutes for the database to update, that means its bugged.
### Since 4.0.10 BETA 2
  • Island regeneration should no longer throw an error if a world is disabled.
  • Upgrades and boosters should no longer break the plugin when maxed out.
  • Stacked blocks and spawners from supported plugins should no longer disappear from the database when the island is unloaded.
  • Spawn support was updated, including spawnOnIsland, which means we should be able to support more spawn plugins! Let us know in #suggestions-skyblock if there's one you'd like to see.
  • Block values are back, and this time, you can see how many of each block are on an island! This should use the same exact config file from v3, but you may need to adjust the inventory size in inventories.yml (for v3 parity, use 18).
  • spawnerEnhancement received a small rework, so now your spawners can get a bigger and better boost (and have support for the aforementioned stackers). However, this may break your current configuration. You'll want to add spawnMultiplier under spawnCount for each level you have (and set it to 1 for default).
  • /is info received a small upgrade - you can now use /is info location to get the island info for the island you're standing on (if any).
  • A new permission, INTERACT, has been added, and will fix the problem with signs and item frames. Players can no longer take items out of item frames, either.
  • Visitor placeholders are now available, and the placeholders for enhancements has been changed from upgrades/boosters to enhancements for consistency.
