# Scrawl-canvas v8 - Particles test 004

## Emit particles along the length of a path

#### Test purpose

- Create a Bezier entity along which the Emitter can generate particles, together with user-controlled Wheel entitys to shape the curve.
- Create a particle world object, a Star entity, and a particle Emitter entity using them.
- Check that the Emitter entity generates particles along the entire length of the Bezier curve.
- Create additional, non-user-interactive shape-based entitys (Line, Oval); clone the Emitter entity (and its artefact), assigning each to the new entitys.
- Check that the cloned Emitter entity generate particles along the entire length of the Line and Oval paths.

Touch test: should work as expected. Known issue: moving the pins is inconsistent (because pins are too small on device screens?)
