# Spline-Positions
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.
## Create the Position
1. Create a simple Spline using the Spline tool.\
2. Add a Firework-Position object next to the Spline.
3. In the 3D-Hierachy window drag the Spline into the Firework-Position.\
4. 
**Every stepper event, which is now applied to this position will be arranged along the spline.**
