After the 2D level editor, I wanted to explore creating scenes in three dimensions. The result is a Java application built with libGDX, using OpenGL to render the scene.
The look is deliberately retro. The project focuses on connecting editing tools to the data that describes a level.
Working with documents
- New document: opens a wizard for creating a level.
- Load: selects an existing document.
- Save: writes changes to disk.
- Undo and redo: moves backwards and forwards through editing changes.
The parts of a scene
- Blocks: chooses the geometry and textures for each block’s faces.
- Entities: adds models in
.g3dbformat, with rotation and scale settings. - Decals: places flat elements in 3D space, facing the camera to create a 2.5D appearance.
- Environment: configures ambient lighting, point lights, and the background or skybox.
- Tools: groups utilities such as event-zone creation and street generation.
The source shows how these options fit into a scene-authoring tool.
