Josh Morony has been making Phaser content for years and is currently working on a really interesting-looking bushcraft survival game. In a recent video dev log he explains how he managed to achieve perfectly smooth camera scrolling, while still maintaining the pixel art effect he wanted for his game. We know this is something lots of other Phaser devs aim to achieve, so please watch his video for details!
"I'm building a 2D bushcraft pixel art survival game, and this month I discovered an easy fix to some huge problems I've been having, and also spent a lot of time improving the controls and interactions in the game."
