    Tiled

    Tiled

    Flexible level editor

    ...Tilesets can be modified at any time. Tiled is a general purpose tile map editor for all tile-based games, such as RPGs, platformers or Breakout clones. Tiled was originally written in Java. In 2008, work began to develop a faster, better looking, and easier-to-use version of Tiled based on the Qt framework. This decision was made as the Qt framework has a greater feature set than is offered by the standard Java libraries. Before you can compile Tiled, you must ensure the Qt (>= 5.6) development libraries have been installed as well as the Qbs build tool.

    Kotlin Symbol Processing API

    KSP is Kotlin’s lightweight, idiomatic alternative to Java annotation processing that gives compile-time access to Kotlin program structure. Rather than forcing Kotlin through Java’s annotation APIs, it exposes Kotlin-first symbols—classes, functions, properties, types—so processors can generate code efficiently. The design dramatically reduces incremental build overhead by operating directly on symbols without compiling stubs, which speeds up large multi-module projects.
