Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

kunpocc-quadtree

v0.1.0

Published

基于TypeScript的四叉树库

Readme

kunpocc-quadtree

NPM Version License

一个使用 TypeScript 编写的高性能、易于使用的四叉树库,专为 2D 游戏和模拟中的高效碰撞检测而设计。

✨ 特性

  • TypeScript 支持: 使用 TypeScript 编写,提供完整的类型定义。
  • 多种形状: 支持矩形 (Box)、圆形 (Circle) 和凸多边形 (Polygon)。
  • 高效查询: 通过空间划分优化查询,实现高效的碰撞检测。
  • 性能优化: 内置对象池 (ObjectPool) 以减少垃圾回收,提升性能。
  • 简洁的 API: 易于集成到现有项目中。

📦 安装

npm install kunpocc-quadtree

🚀 使用示例

创建四叉树

import { QuadTree, createCircle, createBox, createPolygon } from 'kunpocc-quadtree';

// 1. 创建四叉树
const maxDepth = 4;  // 树的最大深度
const maxShapes = 20; // 每个节点的最大形状数
const tree = new QuadTree(0, 0, 750, 1334, maxDepth, maxShapes);

创建圆形

const circle = createCircle(10, 1);

创建矩形

const box = createBox(0, 0, 100, 100, 1);

创建多边形

const polygon = createPolygon([new Vec2(0, 0), new Vec2(100, 0), new Vec2(100, 100), new Vec2(0, 100)], 1);

插入形状

tree.insert(circle);
tree.insert(box);
tree.insert(polygon);

碰撞检测

const shapes = tree.collide(shape, 1);

更新四叉树

tree.update();
