Constellation Draw-On

Constellation effect for 2D games: a glowing line draws through the stars and each one lights up as the pen reaches it, then the figure shines and fades. Seamless loop for skill trees and star maps.

Constellation Draw-On is an HD effect that loops seamlessly every 3 seconds, drawn on a 512 by 400 canvas. It is built from 1 particle emitter and 1 glowing stroke. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Constellation Draw-On is drawn with 1 glowing stroke, lines with a hot core and a soft glow traced along their shapes, plus 1 particle emitter. Techniques worth a look: keyframed parameters and post filters (bloom).

Every layer emits continuously and the 3 s loop closes seamlessly, so it can run for as long as you need. To recolour the line, select "Star line" and change Core and Glow; Start and End set how much of it is drawn. 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.

Step by step: Unity, Godot 4, Roblox, GameMaker, Phaser and PixiJS, Aseprite, Web games (live runtime). Drawn with additive blending: see glow effects without a black box.
