Sleep Status Effect

A sleep status on a character: soft Z letters drift up one after another while a calm night aura breathes, dream stars twinkle and a sleepy bubble swells and pops. Loops seamlessly.

Sleep Status Effect is an HD effect that loops seamlessly every 2.4 seconds, drawn on a 320 by 320 canvas. It is built from 7 particle emitters and 4 text layers. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Sleep Status Effect stacks 7 particle emitters, each with its own job. Techniques worth a look: styled text animated letter by letter, keyframed parameters and post filters (bloom and vignette).

It loops seamlessly every 2.4 s, and one layer fires in bursts, so it pulses instead of flowing evenly. Start times are staggered from 0 s to 2.28 s, so the layers arrive one after another. To change the words, select "Z z1" and edit Text; Font and the fill colours restyle it. The colour swatches by the downloads recolour every layer at once.

Layers, in draw order

  1. Night Aura, Floor Glowparticles / additiveA single long-lived particle that stays for the whole loop.
  2. Z z1, Z z2, Z z3 +1textThe words "Z" in Luckiest Guy. Its letters pop in one after another. At the end they fade away.
  3. Sleep Bubble, Bubble Fillparticles / additiveA single long-lived particle that stays for the whole loop. It swells and then shrinks away.
  4. Bubble Popparticles / additiveOne burst of 10 soft glows from a ring at 2.28 s. They fall under gravity. Colours range between white and pale blue.
  5. Dream Starsparticles / additiveA steady stream of image sprites across a box. They sway from side to side. Colours range between pale gold and pale blue.
  6. Night Motesparticles / additiveA steady stream of soft glows across a box. They sway from side to side. Colours range between white and pale 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.
