Spider Swarm

Black spiders pour in from every side of a stone floor and skitter across it in stop-start dashes with scuttling legs, keeping apart as they swarm. A seamless top-down 2D swarm loop for dungeons and horror games.

Spider Swarm is an HD effect that loops seamlessly every 4 seconds, drawn on a 384 by 384 canvas. It is built from 3 particle emitters.

HOW IT'S MADE

Spider Swarm is a compact effect made from 2 particle emitters. Techniques worth a look: particles that push each other apart, flipbook sprites and post filters (vignette). A scene layer (ground or a prop) shows in the studio for context and stays out of every export.

Every layer emits continuously and the 4 s loop closes seamlessly, so it can run for as long as you need. To change its colour, select "Spiders" in the studio and edit Colour A and Colour B. Size on the same layer sets how big its particles are.

Layers, in draw order

USING IT IN YOUR GAME

Phaser, PixiJS
The PNG sheet is a plain grid of frames that both can slice. A TexturePacker JSON atlas comes with a plan, from the studio.
Unity
Import the PNG sheet as a Sprite with Mode set to Multiple and slice it, or open the effect in the studio for a ready-made grid.
Godot 4, GameMaker, Aseprite
Open it in the studio and pick your engine in Export: with a plan, it writes the files that engine imports.
Web and chat
The GIF plays anywhere; the APNG keeps soft edges on any background.
