A Voxelize world handles the chunk loading and rendering, as well as any 3D objects. This class extends the ThreeJS Scene class. This means that you can add any ThreeJS objects to the world, and they will be rendered. The world also implements NetIntercept, which means it intercepts chunk-related packets from the server and constructs chunk meshes from them. You can optionally disable this by setting shouldGenerateChunkMeshes to false in the options.

There are a couple components that are by default created by the world that holds data:

World.registry: A block registry that handles block textures and block instances.
World.chunks: A chunk manager that stores all the chunks in the world.
World.physics: A physics engine that handles voxel AABB physics simulation of client-side physics.
World.loader: An asset loader that handles loading textures and other assets.
World.sky: A sky that can render the sky and the sun.
World.clouds: A clouds that renders the cubical clouds.

One thing to keep in mind that there are no specific setters like setVoxelByVoxel or setVoxelRotationByVoxel. This is because, instead, you should use updateVoxel and updateVoxels to update voxels.

Example

const world = new VOXELIZE.World();

// Update the voxel at `(0, 0, 0)` to a voxel type `12` in the world across the network.
world.updateVoxel(0, 0, 0, 12)

// Register the interceptor with the network.
network.register(world);

// Register an image to block sides.
world.applyBlockTexture("Test", VOXELIZE.ALL_FACES, "https://example.com/test.png");

// Update the world every frame.
world.update(controls.position);
