## What it is
KTX is a collection of modular Kotlin extensions for the libGDX game framework, leveraging Kotlin features like coroutines, type-safe builders, and operator overloads to improve libGDX's ergonomics. It ships as many small modules covering GUI, physics, assets, ECS, math, logging, and more, for desktop, Android, and iOS targets.

## Use cases
- write a libGDX game in Kotlin with idiomatic APIs
- build Scene2D UIs with type-safe Kotlin builders
- load game assets asynchronously with coroutines
- set up Box2D physics with Kotlin DSL
- use Ashley or Artemis ECS with Kotlin utilities
- reduce boilerplate in libGDX logging and collections

## When to choose
- you use libGDX with Kotlin and want less boilerplate
- you want modular opt-in utilities rather than a full framework rewrite
- you need coroutine-based async asset loading on libGDX

## When to avoid
- your project is pure Java on libGDX
- you use a different game engine like Godot or Unity
- you need a complete engine rather than extensions

## Facets
- artifact type: library
- maturity: active
- function: game-engine, concurrency, logging, serialization, internationalization, math, gui
- domain: cross-platform, developer-tools
- platform: jvm, cross-platform
- tags: kotlin, libgdx, kotlin-extensions, coroutines, scene2d, box2d, ecs, type-safe-builders, gamedev, modular, game-development, android, desktop, ios
