In the project I’m working on I’m using a script almost identical to the one in the space shooter tutorial, but it doesn’t seem to create a new shot when I press Fire1. The shots in my project are empty gameobjects with particle systems as children and no other components, so it may be possible that I need a rigidbody component or a script that defines the shot’s velocity. Or maybe there’s an issue with the particle system not starting after it’s instantiated. 
Line 11. “Update” the “U” has to be capitalized.
Thanks! I actually didn’t notice that. I fixed it, but I have to wait until another script is debugged before i can test the change.
