The code:

 print(wep == null);
print("inside method: " + wep.weaponName); //this line prints the correct value. It also returns a null reference exception.

The output:

2 print lines, 3 debug lines and an error… its not null… and then suddenly it is. Needless to say, I’m pretty stumped here. Any help? Thanks

It’s pretty obvious that this code is running twice. You probably have two copies of this script in your scene.

@PraetorBlue Thanks for the reply, I hadn’t considered that. Oops. I’ll post later on the results of checking that.
