ParticlesStatus

Represents the current operational state of a particle emitter.

ParticlesStatus tracks whether an emitter is actively creating new particles and whether any existing particles are still visible. This is useful for:

• Determining when a particle effect has completely finished
• Optimizing update loops (skip idle emitters)
• Triggering cleanup or follow-up effects
• UI feedback about effect state

The status transitions automatically based on emission state and active particles:

• IDLE → EMITTING: When emission starts
• EMITTING → SPREADING: When emission stops but particles remain
• EMITTING → IDLE: When emission stops and no particles exist
• SPREADING → IDLE: When all particles have expired

// Wait for explosion to finish before removing
emitter.explode(50);
emitter.onStatusChange(null, (status) -> {
    if (status == IDLE) {
        emitter.destroy();
    }
});

// Check if effect is active
if (emitter.status != IDLE) {
    // Effect is still visible
}

IDLE #

IDLE

No activity - not emitting and no particles visible.

This is the default state and indicates the emitter is completely inactive. No particles are being created or updated.

Common scenarios:

• Initial state before first emission
• After all particles have expired
• After calling stop() with no remaining particles

EMITTING #

EMITTING

Actively creating new particles.

The emitter is currently generating particles, either through:

• Continuous emission via emitContinuously()
• In progress burst via explode()
• Manual emission via emitParticle()

There are usually visible particles in this state, though it's possible to be EMITTING with no visible particles if they have very short or zero lifespans.

SPREADING #

SPREADING

Not emitting new particles, but existing particles are still animating.

The emitter has stopped creating new particles but previously emitted particles are still visible and updating. This state continues until all particles have expired or been removed.

Common scenarios:

• After calling stop() with particles still alive
• After a burst completes with long-lived particles
• After continuous emission ends
