Energy Outline Aura

Energy outline aura effect for 2D games: a crackling electric outline hugs the character sprite while bright arcs race around it and sparks rise. Works on any sprite. Seamless loop.

Energy Outline Aura is an HD effect that loops seamlessly every 2 seconds, drawn on a 320 by 320 canvas. It is built from 1 particle emitter and 4 glowing strokes. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Energy Outline Aura is drawn with 4 glowing strokes, lines with a hot core and a soft glow traced along their shapes, plus 1 particle emitter. Techniques worth a look: particles stretched along their motion and post filters (bloom).

Every layer emits continuously and the 2 s loop closes seamlessly, so it can run for as long as you need. To recolour the line, select "Outer halo" and change Core and Glow; Start and End set how much of it is drawn. To see it on your own character, press Use my sprite in the studio: every layer follows the new sprite. The colour swatches by the downloads recolour every layer at once.

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.
Blend mode
This effect is made of light. For the same glow in your game, draw the sprite with additive blending, or export it on black from the studio for additive shaders.
