Lerpz tutorial page 22

I’m new to unity and particle systems, and I’m not sure how to handle the changes in the unity particle system since the creation of the tutorial. How should I compensate for the changes in unity since the tutorial? Help is appreciated.

The problem is that I don’t know how to remake the jet stream. I will try learn the shuriken system then do it myself though , thanks. However, now the game scene wont load! Not sure whats wrong but i’ve restarted my machine and re-imported everything and it still wont load. Is this a common problem? I don’t know what to do!
