Java Vector Nexus Engine

Modern, modular 2D game engine with a lightweight scene graph, simple physics, a custom DSL (JES) for content, and a JavaFX Editor for iteration.

• Modules: core, swing, fx, scripting, runtime, editor
• Rendering backends: Swing (swing) and JavaFX (fx)
• Scene editor: Open a JES file, preview, select entities, tweak properties live

Quick Start

Prereqs: JDK 17+, Gradle (wrapper included).

Run Editor

./gradlew :editor:run

Modules

• core: scene graph (Scene2DBase, Entity2D), components (Panel2D, Label2D, Sprite2D), physics (RigidBody2D, PhysicsWorld2D)
• swing: Swing implementation of Blitter2D
• fx: JavaFX implementation FxBlitter2D and app launcher helpers
• scripting: JES tokenizer, parser, AST, and loader → builds JesScene2D
• runtime: command-line runner (loads JES with --jes, selects UI via --ui)
• editor: JavaFX### Editor
• JavaFX-based scene preview
• Entity selection and property inspection
• Scene Graph panel for named entity navigation
• Inspector panels for all component types
  • Label2D: text, size, bold, align, color
  • Sprite2D: image path, size, alpha, origin
  • Panel2D: dimensions
  • PhysicsBody2D: mass, restitution
• Canvas picking for all entity types
• Hot reload supportation
