As a software engineer and board game enthusiast, I wanted to solve a common problem in our office: organizing our weekly board game nights. While we had a regular schedule (Friday afternoons), we needed a better way to:

Remind people about the upcoming session
Suggest games to play
Get quick feedback on game preferences

This led me to create a Slack bot that would handle these tasks automatically. In this post, I’ll share my journey of building this bot using TypeScript, Slack’s Web API, and GitHub Actions.

In this article, I’ll walk through how culling works in PixiJS v8, highlight some nuances, and share my personal insights on its usage.

It is a common scenario to have dynamic information within an animation, such as UI with dynamic text or a character holding different items. In such cases, we may want to add a child Pixi object (such as BitmapText, Sprite, Container, or even another Spine) to a slot of a Spine animation and have it follow the slot’s transformation during the animation.

Transitioning from Unity to Pixi.js, one noticeable absence was the sliced sprites, especially when working on resizable UI elements like progress bars. Thankfully, Pixi.js offers a comparable component known as NineSlicePlane, which resembles Unity’s sliced sprites in function. Although there are few resources and examples available for NineSlicePlane, this article aims to delve deeper into its behavior and outline how it aligns with my expectations.

I’ve been developing a casual game where each level is designed and saved as a prefab. While it works fine in the Editor, it causes severe performance issues in mobile devices, especially Android. The game freezes for over 10 seconds whenever a level is loaded. To solve this problem, we decided to optimize the game by converting all the level prefabs into scenes. This allows us to utilize Unity’s addictive scene loading, which also enables us to show loading progress.

You’re probably familiar with house ads (or cross-promotion ads) in mobile games. Famous game publishers like Vodoo use house ads extensively to cross-promo their products. While you can put the house ads locally and pre-built them in the apps, having a server to serve the API and assets can give you live control of the ads. You can also use this as app event notices, to gives dynamic information and interaction with your users. This article will walk you through how to create the API calls with Laravel step-by-step.
