Change SpriteRenderer Color Using Script

I am trying to change the color of a sprite. I do not know if this matters, but it is animated and the child of another object. I am able to kind of sort of change the color but something is not right. I have tried a few things guided by threads I found in the forums, but it still is not 100% correct.

I want to change the color to one of three based on a condition; yellow, orange, red. To do this I created some private variables including their alpha.

Code (CSharp):

1. private Color shieldYellow = new Color(Color.yellow.r, Color.yellow.g, Color.yellow.b, 125.0f);
2.     private Color shieldOrange = new Color(255.0f, 153.0f, 51.0f, 125.0f);
3.     private Color sheildRed = new Color(Color.red.r, Color.red.g, Color.red.b, 125.0f);

When I play the game and the conditions are met the colors does change. For Yellow and Red the alpha value is ignored and gets set to 255. For Orange everything is ignored and the normal white color of the original sprite is displayed.

 

You need to post relevant code.

I will post the code where I set the spriterenderer's color to one of my colors as soon as I can; I am back at work.

 

Here is the code for the Shield class.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Shield : MonoBehaviour
5. {
6.     public int initialHitPoints = 30;
7.  
8.     private int hitPoints;
9.     private SpriteRenderer spriteRender;
10.     private Color shieldYellow = new Color(Color.yellow.r, Color.yellow.g, Color.yellow.b, 125.0f);
11.     private Color shieldOrange = new Color(255.0f, 153.0f, 51.0f, 125.0f);
12.     private Color sheildRed = new Color(Color.red.r, Color.red.g, Color.red.b, 125.0f);
13.    
14.     public void RefreshShield()
15.     {
16.         spriteRender = GetComponentInChildren<SpriteRenderer>();
17.         hitPoints = initialHitPoints;
18.         spriteRender.color = shieldYellow;
19.     }
20.  
21.     public virtual void CalculateHit(int amount)
22.     {
23.         hitPoints -= amount;
24.         spriteRender.color = DetermineShieldColor();
25.         if (hitPoints <= 0)
26.         {
27.             gameObject.SetActive(false);
28.         }
29.     }
30.  
31.     private Color DetermineShieldColor()
32.     {
33.         if(hitPoints < initialHitPoints && hitPoints > 10)
34.         {
35.             return shieldOrange;
36.         }
37.         if(hitPoints <= 10)
38.         {
39.             return sheildRed;
40.         }
41.         return shieldYellow;
42.     }
43. }
44.  

 

Actually, I just looked at the original post again and realized that was enough, sorry. You're treating Color like Color32 (except with floats), but they don't work the same at all.

Thank you. I thought I had looked at the Color properly but upon further investigation and reading I found what works.

Code (CSharp):

1. private Color shieldYellow = new Color(Color.yellow.r, Color.yellow.g, Color.yellow.b, .5f);
2.     private Color shieldOrange = new Color(1, .3f, .1f, .4f);
3.     private Color shieldRed = new Color(Color.red.r, Color.red.g, Color.red.b, .3f);
