Mathf.Lerp not working in the Awake function?

Hi,

I'm trying to get a blood effect for the camera every time my player is hit, by changing the material of a red colored material that's on a plane in from of the camera at run time.

My code works in the Update function, but since it has to happen every time my player is shot (which will happen a lot and in quick succession) I need the material to reset and restart after having been shot.

This is my code:

Code (CSharp):

1.   void Awake()
2.     {
3.         //time = 0;
4.         //Color c = rend.material.GetColor("_TintColor");
5.         //c = new Color(1f, 1f, 1f, 1f);
6.  
7.         StartCoroutine(BloodFx());
8. }
9.  
10.     }
11.     IEnumerator BloodFx()
12.     {
13.  
14.         yield return new WaitForSeconds(0f);
15.         Color c = rend.material.GetColor("_TintColor");
16.         c.a = Mathf.Lerp(.20f, 0.0f, Time.time);
17.         rend.material.SetColor("_TintColor", c);
18.     }

As you can see I've tried solving my problem with a coroutine that is called on Awake, but my Mathf.Lerp only works in the Update function not on Awake and only once (It doesn't reset).

Does anybody know how I could get this to work as I want it to? I'd really appreciate the help, thanks.

 

Does this compile? What is this } on line 8 for?

To get useful help, you need to post the entire script.

 

You're right, I added a bracket too many after pasting the original code by mistake. Here's the whole script. There's really nothing else there:

Code (CSharp):

1.  public Renderer rend;
2.     float time;
3.  
4.     public Material[] materials;
5.     public GameObject parent;
6.  
7.     void Awake()
8.     {
9.         //time = 0;
10.         //Color c = rend.material.GetColor("_TintColor");
11.         //c = new Color(1f, 1f, 1f, 1f);
12.         StartCoroutine(BloodFx());
13.  
14.     }
15.     IEnumerator BloodFx()
16.     {
17.  
18.         yield return new WaitForSeconds(0f);
19.         Color c = rend.material.GetColor("_TintColor");
20.         c.a = Mathf.Lerp(.20f, 0.0f, Time.time);
21.         rend.material.SetColor("_TintColor", c);
22.     }
23.     void Update()
24.     {
25.      
26.             //Color c = rend.material.GetColor("_TintColor");
27.             //c.a = Mathf.Lerp(.20f, 0.0f, Time.time);
28.             //rend.material.SetColor("_TintColor", c);
29.        
30.      
31.      
32.         //time += 0.08f * Time.deltaTime;
33.         //RateOverTime = Mathf.Lerp(0f, 1f, time);
34.         //rend.materials[0].SetFloat("_Cutoff", RateOverTime);
35.  
36.  
37.  
38.     }
39. }
