Iskandert's Library
by Unfamily
Iskandert's Library is a NeoForge library mod that supplies reusable functions to other projects by Iskandert's Team, and it is required by two catalog mods.
What it does
The library gathers building blocks used across Iskandert's Team projects, focused on practical gameplay systems such as structures, stages, markers, shops and teams, along with developer utilities and parsing helpers. Iskandert's Utilities and Colossal Reactors depend on it, so both need it installed on the same side.
Structures are defined through JSON files that are discovered when the game loads and registered at runtime. A placement engine then places them in the world, applying validation, property rules and optional behaviors, and a lightweight per-player history supports undo. Currency balances and team grouping are also handled here, and an explosion routine runs progressively over time to limit lag.
Key features
Structure placement engine
Places structures in the world after validating them, applying their properties and optional behaviors.
Runtime structure definitions
Structures are read from external JSON files and registered at runtime, with pattern keys and overwrite rules.
Per-player undo history
Each player's placements are recorded so that they can be reverted, without a large storage cost.
Stage registry
A generic registry gates content and tracks progression across different scopes.
Teams and balances
Players can be grouped into teams that share currency balances stored by the library.
Developer marker rendering
Helpers draw markers over areas, selections and scans to make debugging and automation easier.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.

Use cases
Building structures from JSON

Debugging world areas
Developers can render markers and scans on screen to inspect selected regions during testing.
Who it’s for: Mod developers building on Iskandert's Team projects, and players who use Iskandert's Utilities or Colossal Reactors, which require it.
