Struct ShapeRegistry 

pub struct ShapeRegistry {
    shapes: Vec<VoxelShape>,
    allows_registering: bool,
}

Registry for VoxelShapes.

Shapes are registered once and referenced by ShapeId. This allows deduplication of shapes and compact storage of shape references.

Vanilla shapes are registered at startup. Plugins can register additional shapes for custom blocks.

Fields

shapes: Vec<VoxelShape>

allows_registering: bool
