Coin Stack Growing: Gold coins drop one by one onto a growing stack, each landing with a sparkle and a click ring, then the full stack is collected in a gold poof.

Coin Stack Growing

Gold coins drop one by one onto a growing stack, each landing with a sparkle and a click ring, then the full stack is collected in a gold poof. A seamless loop for idle income and savings.

Coin Stack Growing is an HD effect that loops seamlessly every 2.6 seconds, drawn on a 512 by 512 canvas. It is built from 6 particle emitters and 1 glowing stroke. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Coin Stack Growing stacks 6 particle emitters, each with its own job. Techniques worth a look: glowing strokes traced along shapes, particles stretched along their motion, keyframed parameters and post filters (bloom).

It loops seamlessly every 2.6 s, and 5 of its layers fire in bursts, so it pulses instead of flowing evenly. Start times are staggered from 0 s to 2.25 s, so the layers arrive one after another. To change its colour, select "Collect Flash" in the studio and edit Colour A and Colour B. Size on the same layer sets how big its particles are. 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.
