I just released FloodFill2D: a lightweight TypeScript utility for flood fill on 2D grids. Useful for tilemaps, match-3 games, region detection and more. Demo: triqui.github.io/floodfill2d/de… GitHub: github.com/triqui/floodfi…

Clean, fully paginated level selection system built in Phaser 4 with TypeScript, featuring horizontal drag, direction-aware snap, mouse wheel and event-driven thumbnails. Complete source code available for download, ready to use and extend bit.ly/46vzOp8

HTML5 platformer engine inspired by "Be Brave, Barb", built without physics. Hero walks along a perimeter, switches between four gravity directions, and reattaches to surfaces using CCD, driven by pure geometry. Phaser 4 + TypeScript source code available bit.ly/4aAeeAO

@guidorosso @rive_app @contra I must give it a try

Rift Rider is a game built entirely in @rive_app by Fernanda Marques in just 6 days. One of the winners of our recent Scripting Challenge with @contra.

A dense grid hides simple shapes. This JavaScript example uses a greedy algorithm to extract the true external perimeter from binary grid data, collapsing hundreds of cells into a geometric outline. Then,rendering, collision and movement, becomes simpler - bit.ly/4tl30ZF

A Tiled collision layer is just a dense grid of cells. By applying greedy rectangle merging, that grid can be reduced to a small set of non-overlapping rectanglesthat are far cheaper to use at runtime. Full JavaScript example available with source code bit.ly/3NReu6Z

Greedy rectangle merging is a practical way to simplify dense binary grids into a small set of axis-aligned rectangles. By making local decisions and never backtracking, the same area can be represented with far fewer geometric primitives. JS source code: bit.ly/4qG5kbW

Gravity-rotating movement system built with Phaser 4 and TypeScript, where a character walks around floating terrain by dynamically reassigning gravity instead of falling off edges. Full project available for free at bit.ly/4bIHI1C

@nezavami Thanks!! It’s nice to refresh the old concepts once in a while. Tomorrow I’m uploading a Phaser tutorial, then it’s back to pure JavaScript.

@triqui I just want to say that I really appreciate your later articles explaining fundamental concepts (such as PRNG) using pure JavaScript without any libraries. Excellent work!

QuadTrees organize space instead of objects, allowing spatial queries to skip irrelevant areas with a single check. This makes proximity searches and collision detection far more efficient in games and interactive applications. Interactive example at bit.ly/4jKRFh6

How many of you?

Randomness is rarely truly random in games. This post explains how Mulberry32 turns a single seed into a fully reproducible sequence of values, with a minimal JavaScript demo and real-world videogame applications bit.ly/3L6svNj

Running modern text-to-speech models locally on Windows is anything but trivial. This guide walks through a clean Chatterbox Turbo setup, from Python and virtual environments to PyTorch pitfalls, showing how to get reliable audio output without guesswork - bit.ly/4qOaouJ

I strongly agree. Remember: if you can do something with vibe coding, then ANYONE can do the same thing with vibe coding. Do you really want to be just one more in the crowd?

@guidorosso Just sent a message

Looking for a few indie devs to push what’s possible with Rive Scripting 🚀 UI, games, companion apps, full experiences, or any weird interactive idea you’ve been itching to build. If you love mixing design, animation, and code (and maybe have a soft spot for Flash), DM me.

Real-Time vs Delayed Keyboard Input in JavaScript. Learn to use keyup and keydown events together with requestAnimationFrame to simulate a keyboard input delay. Video tutorial: youtube.com/watch?v=HouoBw… (please subscribe to my newborn YT) Blog post: bit.ly/489ITEb

Build a fully 3D Wheel of Fortune using only HTML, CSS and JavaScript, with pure geometry and a few transforms. Watch it spin in real 3D and see how a handful of divs can create a smooth, random wheel animation. Source: bit.ly/47imLbr Video: youtube.com/watch?v=16O4aN…

@KenneyNL @SketchUp Great job 💪🏼💪🏼

Yesterday I spent an hour with my girlfriend teaching her how 3D model (using @SketchUp), she made a lamp! So proud 🫠 You should all encourage her!

@VoidmawGames I liked it, I reviewed it for an Italian magazine thegamesmachine.it/katanaut-pc/ka…

Hi, I’m Eugene. I finished my first game, Katanaut. It hit 52k wishlists in 10 months… and I released it between Silksong and Hades 2. Average peak players: 11. AMA.

Use named functions for clarity and debugging. Use arrow functions for coincise callbacks and functional patterns. Use anonymous functions only when needed, otherwise prefer arrow.
