VoxelForge is a Unity capstone project focused on building the core systems behind a Minecraft-style voxel sandbox game.
This project is not trying to become a Minecraft replacement, competitor, or commercial clone. It is a learning-focused prototype designed to recreate the foundational technical ideas behind block-based sandbox games: chunked terrain, voxel data storage, procedural generation, optimized mesh creation, and basic block interaction.
The goal of VoxelForge is to demonstrate how a voxel engine works from the ground up using Unity and C#.
Instead of creating every block as a separate GameObject, the world is stored as voxel data and rendered through optimized chunk meshes. This makes the project more focused on real engine architecture rather than simple block placement.
- Minecraft-style first-person block interaction
- Chunk-based world structure
- Procedural terrain generation
- Optimized voxel mesh generation
- Face culling to avoid rendering hidden block faces
- Single mesh per chunk for better performance
- Texture atlas support for block textures
- Basic block breaking and placement
- Expandable block type system
- Foundation for future features like caves, trees, saving/loading, and inventory
VoxelForge is built around performance-aware voxel engine design.
Key technical ideas include:
- Storing voxel data in 1D arrays for better memory layout
- Generating chunk meshes manually
- Rendering only visible block faces
- Using a single material and texture atlas
- Managing active chunks around the player
- Supporting cross-chunk block checks for clean chunk borders
- Updating nearby chunk meshes when edge blocks are changed
- Voxel constants
- Block type IDs
- Basic chunk data
- Mesh generation
- Flat test terrain
- Multiple chunks
- Chunk coordinate system
- Player-based chunk loading
- Global block lookup
- Perlin noise terrain height
- Grass, dirt, stone, and bedrock layers
- Basic terrain variation
- Raycast-based block breaking
- Raycast-based block placement
- Mesh updates after block changes
- Neighbor chunk updates at chunk borders
- Simple trees
- Caves
- Hotbar UI
- Basic inventory
- Save/load system
- Day/night cycle
- Unity
- C#
- Universal Render Pipeline
- Procedural mesh generation
- Texture atlas workflow
- Git and GitHub for version control
This project is being developed as a capstone project for a Unity course.
The main purpose is to learn and demonstrate:
- Unity scripting
- C# architecture
- Procedural generation
- Mesh construction
- Data-oriented thinking
- Runtime optimization
- Game system organization
- GitHub project management
VoxelForge focuses on the engine core first.
This project does not currently aim to include:
- Multiplayer
- Redstone-like systems
- Advanced AI mobs
- Infinite world saving
- Complex crafting
- Commercial release systems
Those features may be explored later, but the priority is to build a solid voxel engine foundation first.
