Island++

The mod is a fork of Trident and extends it with many additional features, focused on fishing. Its modules report calculations that depend on the current spot, tides, upgrades, augments and supplies, and they work in grotto spots as well. Each module can be read in a compact base view, which gives a short overview, or an expanded view on the right, where dropdowns open detailed breakdowns. Players on the MCC Island server use it to keep track of their fishing gear: a colour-coded bait line, remaining supplies, augment uses and maximum remaining counts, overclock levels and the active overclocks and augments equipped.

Other additions include a rarity overlay that outlines items behind them, blueprint indicators that show ownership status with a diamond icon for blueprints the player owns, a focus mode that pushes the game countdown to the front of the screen, and a kill feed in the style of competitive shooters. The config is built with Yet Another Config Lib, and Fabric Language Kotlin is required.

Island++ is open source under the GNU Lesser General Public License v3.0 only. It is published for Fabric only, with a single game version, 1.21.8, and the latest file, 1.4.1, dates from 2025-10-08. Installing it is needed on the client alone, since the server does not need it.
