Particle Spiral effects

Can you explain how to use the particle spiral effects such as the following link :

Can you give the steps in detail?
I am still confused by the explanation

what dont u understand? Just make a prefab from a particle emitter (legacy) which has a particle renderer and optional a particle animator attached, then crate a empty GO in ur scenen, put the spiral-script on the empty GO and drag ur particleprefab in the slot provided by the script. Then have fun experimentign with the values to get something nice (this can take some time)… hope this helps!

thank you… i’ll try it… if there is I’m confused, I will ask again

Remember to add Component>Effect>LegacyParticles…

I got caught out just adding a particle system and got the same error :wink:
