A spatial search μlibrary powered by GameplayKit 👾
Welcome to Sight, a Swift spatial search μlibrary. Its primary goal is to extend Apple's
Sight helps you quickly determine which object is closest to a given position.
This is done via a
Region instance, which represents the space where all the objects are positioned in.
import Sight // Define a region with bounds and search radius. let region = Region<String>( minBounds: SIMD2(x: 0, y: 0), maxBounds: SIMD2(x: 1, y: 1), searchRadius: 0.3 ) // Place objects in the region. region.add("A", at: SIMD2(x: 0, y: 0.1)) region.add("B", at: SIMD2(x: 0.5, y: 0)) region.add("C", at: SIMD2(x: 0, y: 0.8)) // Find the closest object to any position. region.closestValue(to: SIMD2(x: 0.5, y: 0.2)) // "B" region.closestValue(to: SIMD2(x: 1, y: 0)) // nil
Region is optimized for spatial searches, this is why during its initialization both search radius and its bounds are required.
