It’s a micro-optimization, but it also isn’t hard to use in any way, so it’s probably a gain.

I’ve set up a file that just caches all Animator hashes used in the game, which looks like:

```auto
public static class AnimatorNames {
    public static int Attack = Animator.StringToHash("Attack");
    public static int Idle = Animator.StringToHash("Idle");
    //etc
}

```

Which means that instead of doing `myAnimator.SetTrigger("Attack");`, I do `myAnimator.SetTrigger(AnimatorNames.Attack);`.

This has the added benefit of having a centralized place where all strings used are listed, meaning that if you’re looking at an AnimatorController and are wondering where it’s triggers and bools are used, you have a single place to check.[/Code]
