# numParticlesToEmit

The number of particles the emitter should emit before stopping.

## Declaration

```swift
var numParticlesToEmit: Int { get set }
```

## Mentioned in

Creating Particle Effects

## Discussion

Discussion The default value is 0, which indicates that emitter creates an endless stream of particles. If a non-zero value is provided, then the emitter stops generating particles after it has created the specified number of particles.
