Pixel Art Treasure Chest Open

Pixel art treasure chest opening: the chest rattles, the lid flies open in a burst of god rays and coins and gems pop out, bounce and glint before it settles. Use it for loot drops, reward screens and chest unlocks in RPGs, roguelites and dungeon crawlers.

Pixel Art Treasure Chest Open is a pixel art effect that loops seamlessly every 3 seconds, drawn on a 384 by 336 canvas at 3x pixels. It is built from 12 particle emitters and 9 glowing strokes. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Pixel Art Treasure Chest Open is drawn with 9 glowing strokes, lines with a hot core and a soft glow traced along their shapes, plus 12 particle emitters. Techniques worth a look: sub-emitters set off by other particles, collisions and keyframed parameters. 2 scene layers (ground and props) show in the studio for context and stay out of every export.

It loops seamlessly every 3 s, and 8 of its layers fire in bursts, so it pulses instead of flowing evenly. Start times are staggered from 0 s to 0.53 s, so the layers arrive one after another. To recolour the line, select "Release ring far" and change Core and Glow; Start and End set how much of it is drawn. Pixel size in the Pixel art panel sets how chunky it looks. The colour swatches by the downloads recolour every layer at once.

  5. God ray, God ray, God ray +4stroke / additiveA glowing line traced along a path. Its start and end are keyframed, so it writes itself on and off. It wobbles like unstable energy. It flickers like a failing neon tube.
  6. Coins backparticlesOne burst of 9 dots along a line at 0.49 s. They set off "Coin glint" on impact, fall under gravity, bounce when they hit something and swell and then shrink away. Colour: gold.
  7. Gems blueparticlesOne burst of 3 shards along a line at 0.51 s. They leave "Gem glint" behind them, fall under gravity, bounce when they hit something and swell and then shrink away. Colours range between cyan and blue.

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.
