HOW IT'S MADE

Auto Collect Magnet gets its crackle from 1 lightning bolt (a new jagged path on every strike), backed by 6 particle emitters. Techniques worth a look: magnets, sprite modules, sub-emitters set off by other particles, 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. It carries little colour of its own, so it takes a tint well: select "Coins" and set Colour A and Colour B. Size on the same layer sets how big its particles are.

Layers, in draw order

  1. Field Glowsprite / additiveA placed glow. Extras: keyframed motion.
  2. Field Linesparticles / additiveA steady stream of streaks across a box. They are swallowed by a magnet at its centre and slow down with drag. Colours range between white and pale pink.
  3. Coins, GemsparticlesA steady stream of coins and gems across a box. They set off "Catch Flash" when they die, are swallowed by a magnet at its centre, spin and slow down with drag. Colour: white.

  5. Catch Flashparticles / additiveSoft glows set off by "Coins", "Notes" and "Gems". They grow as they age. Colours range between white and gold.
  6. MagnetspriteA placed image. Extras: shake and glow.
  7. Pole Sparksparticles / additiveA steady stream of streaks along a line. They fall under gravity. Colours range between white and pale pink.
  8. Pole Arclightning / additiveA lightning bolt striking sideways every 0.25 s. It forks into branches.

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.
