supergrid-bindings v0.2.10

supergrid

supergrid: An extremely optimized (safe) spatial hash grid.

This project was bootstrapped by create-neon.

Installing supergrid

Installing supergrid requires a supported version of Node and Rust.

You can install the project with npm. In the project directory, run:

$ npm install

This fully installs the project, including installing any dependencies and running the build.

Building supergrid

If you have already installed the project and only want to run the build, run:

$ npm run build -- --release

This command uses the cargo-cp-artifact utility to run the Rust build and copy the built library into ./index.node.

Example

const Grid = require('supergrid-bindings');
let grid = new Grid(1024, 7); // Hash table size of 1,024,000, with a cell size of 128x128

grid.insert({
    // IDs MUST BE UNIQUE
    id: 0,
    x: 50,
    y: 50,
    width: 100,
    height: 100,
});
grid.insert({
    id: 1,
    x: 300,
    y: 300,
    width: 20,
    height: 20,
});

let intersectingIDs = grid.query({
    x: 0,
    y: 0,
    width: 500,
    height: 500,
});
console.log(intersectingIDs); // [0, 1]
