Emerald Magic Portal

Magic portal effect for 2D games: a ring of emerald energy smoke whirls around a dark gateway while sparks orbit it. Seamless loop, place it on any wall or floor.

Emerald Magic Portal is an HD effect that loops seamlessly every 3 seconds, drawn on a 448 by 448 canvas. It is built from 1 simulated smoke and fire layer and 3 particle emitters. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Emerald Magic Portal is built around a fluid simulation of fire and smoke on a grid, with 3 particle emitters on top. Techniques worth a look: particles feeding the fluid, a vortex, magnets, particles stretched along their motion 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 change the flame colour, select "Portal smoke" and edit Fire colours; Smoke colour sets the smoke. The colour swatches by the downloads recolour every layer at once.

Layers, in draw order

  1. Flashparticles / additiveA single long-lived particle that stays for the whole loop. It grows as it ages.
  2. Portal smokefluidSimulated fire and smoke from a ring. "Energy streams" feed it. It turns in a vortex.
  3. Energy streamsparticles / additiveA steady stream of soft glows from a ring. They swirl around a vortex and feed smoke and heat into the fluid. Colours range between orange and gold.
  4. Motesparticles / additiveA steady stream of streaks from a ring. They swirl around a vortex and are pulled toward a magnet. Colours range between pale teal and teal.

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.
