LittleJS Stress Test

killedbyapixel.github.io

Tiny fast HTML5 game engine!

Even more shocking, it turns out the sprites for this PixiJS speed test are not even colored dynamically! The color is baked into the texture just contains 5 different sprites. Behold the obscene truth... 🙀

PixiJS claims "Unmatched Performance & Speed"

Ok, @pixijs.com, I accept your challenge.

200,000 sprites, under 60 fps with Pixi, over 60 fps with LittleJS. Also, the sprites are all different colors with LittleJS plus the canvas is 1080p. 🤔 #gamedev #javascript #pixijs

I've been continuing to polish LittleJS especially the example browser. It's working super nice now with many easy to follow examples. What mini game demo would you like to see next? 🚂

I just beat Blue Prince, a wonderful game if you are into puzzles, logic, and recreational math. Very well crafted and unique with a great art style. Good sense of humor also. I won't give away anything else except to say I highly recommend it! 📘💎🗝️💙

New prizes added to the jam! @github.com is back as a sponsor with 3x copilot pro for 3 months!

I love using copilot to work with #LittleJS. My new favorite agent prompt is asking it to look over my codebase for small bugs, it always finds something! 😅👍

I just finished up a game dev live stream working on LittleJS and discussing the new features. We fixed a few bugs and improved the lunar lander mini game. Planning to do these more often, at least during the game jam. 😅👍 #gamedev #littlejs

LittleJS rendering system is crazy fast. For the procedural hills in my #js13k game, I just draw a few thousand thin vertical strips. No sweat. 💪🚂

There is another LittleJS game in #JS13K and it's fantastic! 🛩️💥🐈‍⬛

Black Cat Squadron by repsej is a one button shooter based on a real WW2 secret US Navy squadron. There are 10 levels with a final boss and you can continue!
