Question by oliver-jones · Jun 02, 2015 at 10:22 PM · buglist

Odd Behaviour with Lists (Collections.Generic) - Bug?

Okay, this is really odd, and I can't figure it out at all. I'm assuming it's a bug somewhere within Unity. But check this out:

I have two lists:

 var ProfileUsername     : List.<String>;
 var ProfileSubtext        : List.<String>;


I then have this function that creates a new profile, it just adds new entires into the list:

 public function AddNewProfile(){
 
     print("[PROFILE] Add new profile");
 
     ProfileUsername.Add("New Name");
     ProfileSubtext.Add("Subtext tag");
 
     print("Username Count: " + ProfileUsername.Count);
 }    

Whats weird is that is puts both 'New Name' and 'Subtext tag' into my ProfileUsername, and ProfileSubtext:

alt text

How is this happening? My print 'Username Count' also returns a count of 2 entries .

UPDATE

In fact, it adds it to all my List variables within my script.

I just run the code you have above and it seems to work just fine. Only difference is that I have my start function calling AddNewProfile()

 class TryThis extends MonoBehaviour{
     var ProfileUsername : List.<String>;
     var ProfileSubtext : List.<String>;
     
     function Start () {
         AddNewProfile();
     }
 
      public function AddNewProfile(){
      
          print("[PROFILE] Add new profile");
      
          ProfileUsername.Add("New Name");
          ProfileSubtext.Add("Subtext tag");
      
          print("Username Count: " + ProfileUsername.Count);
      } 
  }

There's a possibility that some other scripts in your project might be doing this.
