Lightweight Java Game Library

LWJGL ( is a Java library that enables cross-platform access to popular native APIs useful in the development of graphics (OpenGL/Vulkan), audio (OpenAL) and parallel computing (OpenCL) applications. This access is direct and high-performance, yet also wrapped in a type-safe and user-friendly layer, appropriate for the Java ecosystem. LWJGL is an enabling technology and provides low-level access. It is not a framework and does not provide higher-level utilities than what the native libraries expose. As such, novice programmers are encouraged to try one of the frameworks or game engines that make use of LWJGL, before working directly with the library. If you'd like to contribute, see doc/README for a quick overview of the project structure, installation instructions and configuration options. As of version 3.4.0 and JDK 25, LWJGL supports the FFM API and is fully functional when running with --sun-misc-unsafe-memory-access=deny . See the FFM documentation for details. The build configurator generates Maven & Gradle declarations that can be added to existing projects. This is the easiest way to use LWJGL while developing. To compile and run an LWJGL application, the base and natives JAR files of the core module and each binding used should be added to the classpath. LWJGL extracts the natives to a temporary folder and loads them automatically, so no further configuration is necessary. If more customization is required (e.g. when creating a platform-specific installer) the natives may be extracted manually and loaded via java.library.path . See the Configuration class for more options. For migrating LWJGL 2 code to LWJGL 3, see the Migration Guide. LWJGLX/debug is a Java Agent that will automatically detect a lot of these issues. It can also generate a trace log that's useful when reporting issues to LWJGL. When asking for help or when you suspect a bug in LWJGL, preparing an MVCE (Minimal, Complete, and Verifiable example) that reproduces the issue will improve the chances of a quick and useful response.
