Please format your code properly (including the indentations and removing unnecessary empty lines...) and actually show the error and where it is. $code

idk why its so small

Pobiega•5d ago

and what exactly are lines 18 and 19? the error indicates you are trying to access transform statically, but I can't see any code that actually does that

ReadableOP•5d ago

It’s at the shoot function

ero•5d ago

Gun isn't a Component or a MonoBehaviour, so it doesn't know of a transform member. it tries to access transform from the Weapon class that Gun is nested in. but since accessing transform (which is an instance member) requires a valid instance of Component to be present (which would be this in Weapon), you cannot access that member. what you probably wanted to do is class Gun : Weapon, like you did below with class Throw : Weapon but you should not be nesting classes in this way in the first place
