I need help please.

 

if you remove line 50, does it work then?

Code (CSharp):

1. pistol1 = GetComponent<Animator>();

 

If I remove line 50, the animation not working. What i want is to make recoil.

 

As the error says, Attach a Animator component to the 'muzzle' GameObject

 

When Attach a Animator, animation not working.

 

I fixed
