on page 179 of the book,
I add an audio source to the BobbleMarine-body
then add lines to the gun script.
when running the game I get
MissingComponentException: There is no ‘AudioSource’ attached to the “SpaceMarine” game object, but a script is trying to access it.
You probably need to add an AudioSource to the game object “SpaceMarine”. Or your script needs to check if the component is attached before using it.
