Cannot apply indexting with [] to an expression of type "Animator"

Hi! I'm relatively new to using unity and i wanted to do an animation that plays for the player when he's walking, that being the head bobbing animation. I wanted to have the headbob keep playing when the player let's go ofthe key, but will only play until the end of the animation (AKA not loop). But i'm not sure how to do that, i tried this but it hasnt worked. instead i get "Cannot apply indexting with [] to an expression of type "Animator""

i'm not sure what i'm doing wrong since i'm very new to C# and unity, so i've come here looking for help! Much appreciated!

Error line = 22

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class HeadBobbing : MonoBehaviour
6. {
7.     public Animator Anim;
8.     void Start()
9.     {
10.         Anim = GetComponent<Animator>();
11.     }
12.  
13.     // Update is called once per frame
14.     void Update()
15.     {
16.         if (Input.GetKeyDown((KeyCode.W)))
17.         {
18.             Anim.Play("HeadBob");
19.         }
20.         else if (Input.GetKeyUp(KeyCode.W))
21.         {
22.             Anim["HeadBob"].wrapMode = WrapMode.Once;
23.             if (Anim.GetCurrentAnimatorStateInfo(0).IsName("Headbob"))
24.             {
25.                 Anim.Play("Headbob");
26.             }
27.         }
28.     }
29. }
30.  

 

So, i have no experience with the Animator class, but i looked for the docs on unity and apparently in their example they use a foreach loop, and i don't know why if you can use a foreach loop they wouldn't just make it index-able as well, but according to unity this should work...

Code (CSharp):

1. foreach (AnimationState state in Anim)
2. {
3.     state.wrapMode = state.name == "HeadBob" ? WrapMode.Once : state.wrapMode;
4. }

 

I'm getting a error that says "foreach statement cannot operate on variables of type 'Animator' because 'Animator' does not contain a public instance definition for 'GetEnumerator'

 

Oh, my bad, i was looking at the docs for Animation, not Animator. Bad news, i now very little about this, good news, i managed to find this treasure scattered in the docs of Animator and it might be useful to you.

Animator.GetCurrentAnimatorStateInfo()

but as for setting parameters on an AnamationState in an animator, while indirect, you may be able to utilize these:

Animator.SetTrigger()
and
Animator.ResetTrigger()

 

Alrighty, thanks! I'm still COMPLETELY new to C# and unity, so i'll see what i can do with that! any help is a lot =)
