⭐ Starfoge: A multiplayer pixel art & animation studio that runs in your browser.

Day three, and it finally draws! The whole toolbox landed with six drawing tools and keyboard shortcuts already known by pixel artists. Yesterday’s 37 green tests are 117 today.

Today i want to deep dive in one of the questions i had: why fast strokes come out dotted. The browser only tells the page where the mouse is once per screen frame (~60fps), but a hand can cross half the canvas between two of those reports and a quick zigzag would become a trail of separated dots.

The fix comes in two layers:
First, the browser actually keeps the positions it skipped and hands them back in a bundle with each event, so I ask for those in-between samples.
Second, even those have gaps when the gesture is really fast, so between every pair of samples I draw a tiny line using Bresenham algorithm, the same grid walker my line tool uses, it steps from one pixel to a touching neighbor and can’t skip a cell by construction. So every stroke you see is secretly dozens of tiny straight lines, stitched end to end.

Tomorrow i will start landing Layers to our studio. Thanks for reading and see you on the next devlog :D
