Access Color Adjustment hue shift per script

Hello, I am trying to add a script to my game that changes the hueshift of my color adjustment post processing effect +1 F per second. So the whole game changes color the whole time.

How exactly do I access this via code?

What I currently have:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Rendering;
5. using UnityEngine.Rendering.Universal;
6.  
7. public class AllColorShift : MonoBehaviour
8. {  
9.     public volume myvolume;
10.  
11.     void Update()
12.     {
13.         ColorAdjusment CA;
14.         if(volume.profile.tryGet<ColorAdjusment>(out CA))
15.         {
16.             CA.hueshift.
17.         }
18.     }
19. }
20.  

Please help me.

 

The new post processing system is really finicky for this kind of real-time updating, but give something like this a try:

Code (csharp):

1.  
2.    public Volume volume;
3.    public float timeScale = 1f;
4.  
5.    private ColorAdjustments colorAdjustments;
6.    private VolumeParameter<float> hueShift = new VolumeParameter<float>();
7.  
8.    void Start()
9.    {
10.        volume.profile.TryGet<ColorAdjustments>(out colorAdjustments);
11.  
12.        if(colorAdjustments == null)
13.            Debug.LogError("No ColorAdjustments found on profile");
14.  
15.    }
16.  
17.    void Update()
18.    {
19.        if(colorAdjustments == null)
20.            return;
21.  
22.        hueShift.value = -180f + Mathf.PingPong(Time.time * timeScale, 360f);
23.  
24.        colorAdjustments.hueShift.SetValue(hueShift);
25.    }
26.  

I typed it here so no guarantees it works or is typo-free, but it should get you started.

 

Thank you for your reply. I changed the code a little without error but also without it working.

The code currently sets the hueshift value to the first float, to say, the -180 (in my case the 0), but it does not update it. It just stays there.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Rendering;
5. using UnityEngine.Rendering.HighDefinition;
6.  
7. public class AllColorShift : MonoBehaviour
8. {
9.    public Volume volume;
10.    public float timeScale = 1f;
11.    private VolumeParameter<float> hueShift = new VolumeParameter<float>();
12.    public ColorAdjustments CA;
13.  
14.    void Start()
15.    {
16.  
17.        volume.profile.TryGet<ColorAdjustments>(out CA);
18.        if(CA == null)
19.            Debug.LogError("No ColorAdjustments found on profile");
20.    }
21.    void Update()
22.    {
23.        if(CA == null)
24.        {
25.             return;
26.        }
27.  
28.        hueShift.value = 0 + Mathf.PingPong(timeScale * Time.deltaTime, 360f);
29.        CA.hueShift.SetValue(hueShift);
30.    }
31. }

 

The Mathf.PingPong in your version doesn't have a growing value, so it's going to be static. If you want it to bounce between 0 and 180 only, not -180 to 180, then use:

hueShift.value = Mathf.PingPong(Time.time * timeScale, 180f);

Otherwise the code is working fine from what I can tell, just tested it in 2019.4 LTS.

 

Thank you a ton for your help, it works now.
