Multiple instance of AI script only move one Game Object.

I have this problem when I have two Game Objects with the same Enemy script. They both call the Move function but only one object moves accordingly.

Code (CSharp):

You have the NavMeshAgent and a GameObject defined as "static" so there is only 1 of them. If you remove the "static" keyword I think that will make it so your script works as you would like it to.

 

Thanks that worked. I originally had a static method, that is why they were static.
