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 🙏

Extension class for UnityEngine.GameObject to handling Component

Readme

What?

  • UnityEngine.GameObject の拡張クラスです。
  • 主に GameObject に対する Component 関連の操作を拡張します。

Why?

  • 毎回 if (gameObject.GetComponent<Hoge>() != null) とか書くのが面倒だったのが発端。
  • 「未追加なら追加」的な操作も何回書いたか分からんレベルだったので、同じく拡張する。
  • AddComponent 後にインスタンスフィールドを初期化したくなる衝動に駆られることも多かったので、それも追加。

Install

$ npm install @umm/game-object-extension-component

Usage

using UnityEngine;
// ココがポイント
using GameObjectExtension;

public class Hoge : MonoBehaviour {
    
    public void Start() {
        // コンポーネントの有無をチェック
        if (this.gameObject.HasComponent<Fuga>()) {
            Debug.Log("Hoge has component: Fuga");
        }
        // AddComponent 直後 (= Awake() 直後) に呼び出される処理を記述
        this.gameObject.AddComponent<Piyo>(
            (piyoInstance) => {
                piyoInstance.isPonyo = true;
            }
        );
    }

}

public class Fuga : MonoBehaviour {
    
    public void Start() {
        Piyo piyo;
        // 未追加のハズなので、追加される
        piyo = this.gameObject.GetOrAddComponent<Piyo>();
        // 上で追加済なので、そのインスタンスを取得
        piyo = this.gameObject.GetOrAddComponent<Piyo>();
    }

}

public class Piyo : MonoBehaviour {

    public bool isPonyo = false;

}
  • GameObjectExtension namespace を using するコトで拡張が有効になります。
