# timeStep

The amount of time the simulation advances each time step, in seconds.

## Declaration

```swift
var timeStep: Float { get set }
```

## Discussion

Discussion A smaller number means more time steps are computed each frame, leading to higher simulation accuracy but also higher computation load. Must be positive.
