Frost Screen Edge

Frost creeps in from the screen edges: branching frost veins grow inward, a rime crust and a pale blue vignette close in and flakes sparkle, then it thaws. Loops, for cold damage, frozen status and winter menus.

Frost Screen Edge is an HD effect that loops seamlessly every 4 seconds, drawn on a 512 by 512 canvas. It is built from 4 particle emitters and 10 lightning bolts.

Free download with a transparent background, cropped to the effect, 120 frames at 30 fps. Use it in commercial games, no credit needed.

Licence: use it in any project, including paid commercial games such as a game sold on Steam. There is no per-project licence to buy and no credit needed. Terms.

Roblox: the download is a flipbook for a ParticleEmitter. Set FlipbookLayout to Grid8x8, FlipbookMode to OneShot and Lifetime to 4, then emit one particle per cycle. Roblox setup.

HOW IT'S MADE

Frost Screen Edge gets its crackle from 10 lightning bolts (a new jagged path on every strike), backed by 4 particle emitters. Techniques worth a look: keyframed parameters and post filters (vignette and bloom).

It loops seamlessly every 4 s, and 2 of its layers fire in bursts, so it pulses instead of flowing evenly. Start times are staggered from 0 s to 0.35 s, so the layers arrive one after another. To recolour the lightning, select "Frost Vein" and change Core and Glow; Strike every sets how often it fires.

Layers, in draw order

  1. Rime CrustparticlesOne burst of 56 smoke puffs around a box outline at 0.15 s. They grow as they age. Colours range between white and pale blue.
  2. Rime EdgeparticlesOne burst of 44 smoke puffs around a box outline at 0.15 s. They grow as they age. Colours range between white and pale blue.
  3. Frost Vein, Frost Vein, Frost Vein +3lightning / additiveA lightning bolt striking sideways every 4 s. It forks into branches.
  4. Frost Vein, Frost Veinlightning / additiveA lightning bolt striking downward every 4 s. It forks into branches.
  5. Frost Vein, Frost Veinlightning / additiveA lightning bolt striking upward every 4 s. It forks into branches.
  6. Edge FlakesparticlesA stream of snowflakes around a box outline, its rate keyframed over the loop. They grow as they age. Colours range between white and pale blue.
  7. Glintsparticles / additiveA stream of stars around a box outline, its rate keyframed over the loop. They swell and then shrink away. Colours range between white and pale cyan.

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.
