Problem with debugger or with the script? I can't tell

I'm trying to write an attack routine for a character. It certainly works as intended, but the problem is that the first time I launch the debugger after opening Unity it glitches out and doesn't work as it's suppose to:

This is what it looks like the first time it's run after launching Unity:


And this is what it looks like every time after so long as I don't close Unity:



As you can see, the code DOES do what it's suppose to, but only under specific circumstances. The problem is that I can't find out what those circumstances actually are and how to fix them. If it helps, this is the attack script:

Code (csharp):

1.  
2. protected override void attack()
3.     {
4.         if (comboAttack == 0 && anim.IsPlaying("Melee_attack3") == false)
5.         {
6.             anim.GetClip("Melee_attack").wrapMode = WrapMode.Once;
7.             anim.Play("Melee_attack");
8.             comboAttack++;
9.         }
10.         else if (comboAttack == 1 && anim.IsPlaying("Melee_attack") == false)
11.         {
12.             anim.GetClip("Melee_attack2").wrapMode = WrapMode.Once;
13.             anim.Play("Melee_attack2");
14.             comboAttack++;
15.         }
16.         else if (comboAttack == 2 && anim.IsPlaying("Melee_attack2") == false)
17.         {
18.             anim.GetClip("Melee_attack3").wrapMode = WrapMode.Once;
19.             anim.Play("Melee_attack3");
20.             comboAttack = 0;
21.         }
22.     }

So is the problem the code or is it the debugger? and if it's the latter, will the problem manifest if run on a final build?

 

Falcoshin, there is not enough here for us to figure out whats going on.

 

What more do you need exactly?
