Can't setTrigger() for another GameObject

I have a Game Controller on a Game Controller object and I want to setTrigger(); on the players (another object) animator to trigger his animation. This doesn't work. The following is my code:

Code (CSharp):

1. public class buttonSwap : MonoBehaviour
2. {
3.     [SerializeField]
4.     private GameObject player;
5.     private Animator playerAnim;
6.  
7.  
8.     private void Awake()
9.     {
10.         playerAnim = player.GetComponent<Animator>();
11.     }
12.  
13.     // Start is called before the first frame update
14.     void Start()
15.     {
16.         playerAnim.SetTrigger("keyPressShape");
17.     }
18.  
19.     // Update is called once per frame
20.     void Update()
21.     {
22.         if (Input.GetButtonDown("Fire1"))
23.         {
24.             playerAnim.SetTrigger("keyPressShape");
25.         }
26.     }

 

- you don't need the line 4
- drag and drop your player in the Player Anim slot (it will hook up the Animator)
- you don't need the line 10
- are you sure you call the trigger "keyPressShape"? Exactly this? Can you give us a screenshot of your param tab in the animator?
