Transmute Core API

The Java API gives your game a fixed timestep loop, pixel rendering, and a small set of services. A game is a TransmuteCore subclass: initialize resources, update logic, and render through Manager.

No server, API key, or network connection is needed at runtime. The reference below describes the public authoring surface; generate complete Javadocs with ./gradlew :transmute-core:javadoc.

Source and compatibility

The source is the authority for signatures. Browse core source or generate Javadocs. Published engine coordinates and CLI release tags have separate version histories; use the version your game was tested against.
