If you want to fire many shells along a line, you can create many firework-positions and arrange them on a line. However, this will create many timeline tracks and events, which also has a higher performance impact. In this case it is better to use a Spline instead of a single Firework-Position.&#x20;

## Create the Position

1. Create a simple Spline using the Spline tool.\ <img src="https://4198123652-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MhIYO0xEuDDA2b69m5L%2Fuploads%2FAciYitn1ICxinGCMctUx%2Fimage.png?alt=media&#x26;token=6bea5608-a912-4585-93d6-a1a3339c9bb2" alt="" data-size="original">
2. Add a Firework-Position object next to the Spline.&#x20;
3. In the 3D-Hierachy window drag the Spline into the Firework-Position.\

**Every stepper event, which is now applied to this position will be arranged along the spline.**
