Particle Burst

A radial spray of short-lived particles that marks an impact or a pickup.

Examples

Captured from this page's own interactive demo below.

Overview

A particle burst spawns a handful of small, fast, short-lived particles flying radially out of a point — on a hit landing, a crate breaking, a coin being collected — arcing under light gravity and fading within a second.

It works because real collisions eject debris; even an abstract spray of squares borrows that physical cue, so the event reads as material and consequential rather than as two sprites overlapping.

It's also one of the most flexible reward signals: the same burst tuned gold and upward says 'you gained something', tuned red and outward says 'something got damaged' — direction, color, and count carry the meaning.

Best Practices

Do

✓Keep particles short-lived (0.3–1s) and let them shrink or fade out — lingering debris turns into clutter.
✓Randomize each particle's speed, size, and angle a little — a perfectly even ring reads as mechanical.
✓Add slight gravity or drag so the burst has an arc — pure linear motion looks like a diagram, not debris.

Don't

✕Don't spawn unpooled particle objects per hit — bursts are exactly the high-frequency case object pooling exists for.
✕Don't scale particle count with importance alone — 200 particles on every kill destroys both readability and the framerate budget.
✕Don't tint the burst the same color as the background or the thing it's bursting from — it should separate instantly.

Common Mistakes

⚠Emitting continuously (a rate) instead of a single burst, so the effect reads as smoke rather than impact.
⚠Forgetting Size over Lifetime / Color over Lifetime curves, leaving particles to pop out of existence at full size.
⚠Spawning the burst at the object's pivot instead of the actual contact point, so it visibly detaches from the impact.

Implementation

Paste this into your AI assistant (Cursor, Copilot, Claude) to add the effect to your project.

Prompt

Add the "Particle Burst" game-feel effect to my project: A radial spray of short-lived particles that marks an impact or a pickup.

How it works: A particle burst spawns a handful of small, fast, short-lived particles flying radially out of a point — on a hit landing, a crate breaking, a coin being collected — arcing under light gravity and fading within a second.

Guidelines:
- Keep particles short-lived (0.3–1s) and let them shrink or fade out — lingering debris turns into clutter.
- Randomize each particle's speed, size, and angle a little — a perfectly even ring reads as mechanical.
- Add slight gravity or drag so the burst has an arc — pure linear motion looks like a diagram, not debris.

Avoid:
- Don't spawn unpooled particle objects per hit — bursts are exactly the high-frequency case object pooling exists for.
- Don't scale particle count with importance alone — 200 particles on every kill destroys both readability and the framerate budget.
- Don't tint the burst the same color as the background or the thing it's bursting from — it should separate instantly.

Implement the effect in whatever engine/stack the project already uses and follow its existing code style. Wire it up where it makes sense.
