# emitter::continuous

Continuously emit particles at a fixed rate.

## Declaration

```swift
void emitter::continuous(float rate, float maxBurst)
```

## Parameters

- `rate`: Number of particles per second to emit. If this value results in a fractional number of particles to emit in a given frame, the remainder will be carried into the next frame.
- `maxBurst`: Maximum number of particles to emit in a single frame.
