Animator.SetInteger not working?

Just got started with Mecanim, and it's a lot less intimidating then I originally thought. The first problem I encountered here is with this code:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class NightHawkAndo : MonoBehaviour {
5.    
6.     public PlayerController player;
7.     public float damageGiven;
8.     public float damageToPlayer;
9.     public float health;
10.     public float firerate;
11.     public float moveSpeed;
12.     public GameObject bossDoor;
13.     public bool startFight;
14.     public Animator animator;
15.  
16.     void Start() {
17.         player = GameObject.Find ("player").GetComponent<PlayerController> ();
18.         moveSpeed = 6;
19.         health = 250;
20.         firerate = 5;
21.         bossDoor = GameObject.Find ("bossDoor");
22.         bossDoor.SetActive (false);
23.         animator = GetComponent<Animator> ();
24.         startFight = true;
25.         animator.SetInteger ("bossAttack", -2);
26.     }
27.  
28.     void Update() {
29.         if(health <= 0) {
30.             Destroy (gameObject);
31.         }
32.         if (startFight) {
33.             animator.SetInteger ("bossAttack", -1);
34.             startFight = false;
35.             animator.SetInteger ("bossAttack", 0);
36.         }
37.         Debug.Log(animator.GetInteger("bossAttack"));
38.     }
39.  
40.     void OnTriggerEnter2D(Collider2D col) {
41.         if (col.tag == "Player") {
42.             player.health -= damageToPlayer;
43.         }
44.         if (col.tag == "Bullet") {
45.             health -= player.damage;
46.         }
47.     }
48. }
49.  
50.  

There's a lot going on, but my problem lies in the Update method. Despite startFight being true, the integer is never updated. It stays at 0 during the runtime. Commenting out startFight = false did not stop it from happening, the int just never updates to begin with. Can anyone explain why? Thanks!

 

Because you are immediately setting the value back to 0.

Code (csharp):

1. if (startFight) {
2.     animator.SetInteger ("bossAttack", -1);
3.     startFight = false;
4.     animator.SetInteger ("bossAttack", 0);
5. }

 

Correct, it will always be 0. You are setting it to 0 on line 35.

 

If you want the behaviour of a value that is set true then immediately reverts back to false, use a trigger.

 

Excuse the late response, but I should have clarified what I tried. I've removed and changed multiple lines, and nothing has changed the value. I obviously would have a non-functioning slice of code if it was working properly, but even if I explicitly set the value like this without the Update function:

Code (CSharp):

1. void Awake() {
2.     animator.SetInteger("bossAttack", anyNumber); //Where anyNumber is any integer
3. }

It still remains at 0. Could this require a project refresh or reinstallation?

 

Often this is caused by not actually having the proper animator controller selected. The value won't update if you aren't looking specifically at the animator controller that's attached to the object being animated.

 

This. Also check to make sure in the Animator that the parameter is spelled the same, and that it is an int and not a float or something. It won't throw errors if you set or get something that isn't there.

 

And that the variable your are using really is non zero and hasn't been overridden by the inspector settings.

 

Funnily Enough I ran into the same problem when setting animator values in start. They Seemed to always be 0. I've worked around it using a small delay when setting them in start.

 

Exactly!

 

When you programatically set the animator I believe you need to wait a frame to set the value.

Code (CSharp):

1.  
2.                             modelAnimator.runtimeAnimatorController = previewController;
3.                             StartCoroutine(SetIntegers());
4.  
5.                             IEnumerator SetIntegers()
6.                             {
7.                                 yield return null;
8.                                 modelAnimator.SetInteger(nameof(EAttackType), (int)attackType);
9.                                 modelAnimator.SetInteger(nameof(EMoveType), (int)moveType);
10.  
11.                             }
