[SOLVED]Color Hue Changing(RGB Values) Of Sprite Using C# Script Code?

Hi,

Making some progress...

How would we modify a sprite's RGB values using C# script code?
(color hue change I mean)

Let us know, thanks!

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. static class visualsCoreGlobal
6. {
7.     public static Sprite[] Sprites;
8.     public static GameObject[] SpriteGOs;
9.     public static SpriteRenderer[] SpriteRenderers;
10.  
11.     public static int LoadSprite(int index, string fileName)
12.     {
13.         Sprites[index] = Resources.Load<Sprite>(fileName);
14.         SpriteGOs[index] = new GameObject("Sprites[index]");
15.         SpriteRenderers[index] = SpriteGOs[index].AddComponent<SpriteRenderer>();
16.         SpriteRenderers[index].sprite = Sprites[index];
17.  
18.         return (1);
19.     }
20.  
21.     public static int LoadAllSprites()
22.     {
23.         Sprites = new Sprite[1300];
24.         SpriteGOs = new GameObject[1300];
25.         SpriteRenderers = new SpriteRenderer[1300];
26.  
27.         LoadSprite(0, "Sprites/BG_ScreenFade");
28.  
29.         LoadSprite(1, "Sprites/TS_Logo");
30.  
31.  
32.         return (1);
33.     }
34.  
35.     public static int DrawSprite(int spriteIndex, float screenX, float screenY, float screenZ, float scaleX, float scaleY, float rotation)
36.     {
37.         float xPos = (SpriteRenderers[spriteIndex].bounds.size.x) / (640.0f/screenX);
38.         float yPos = (SpriteRenderers[spriteIndex].bounds.size.y) / (360.0f/screenY);
39.         SpriteRenderers[spriteIndex].transform.localPosition = new Vector3(xPos, yPos, screenZ);
40.  
41.         SpriteRenderers[spriteIndex].transform.localScale = new Vector3(scaleX, scaleY, 1.0f);
42.  
43.         SpriteRenderers[spriteIndex].transform.Rotate(Vector3.forward * rotation);
44.  
45.  
46.         return (1);
47.     }
48. }
49.  
50. public class visualsCore : MonoBehaviour
51. {
52.     // Start is called before the first frame update
53.     void Start()
54.     {
55.        
56.     }
57.  
58.     // Update is called once per frame
59.     void Update()
60.     {
61.        
62.     }
63. }
64.  

 

Sprites cannot change hue. SpriteRenderers can be set to any arbitrary multiplicative hue.

You should familiarize yourself with the SpriteRenderer documentation.

https://docs.unity3d.com/ScriptReference/SpriteRenderer.html

You will notice a field that looks a lot like

.color

 

Got it working, thanks!

SpriteRenderers[spriteIndex].color = new Vector4(red, green, blue, alpha);
