Visual Effect Graph

Hey Folks,

i am trying to access via c# the exposed parameters of the visual effects graph. But i don`t know how to access them. There is only verly little documentation for it. What i actually want to do is to control an "exposed" float via Script. I have enabled the "expose" option in the graph for an float, but can`t find the variable. The script is attached to the gameobject where the visual effect object is attached to.

Thanks for any help!

Any help is appreciated!

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.VFX;
5. using UnityEditor.VFX;
6. using UnityEditor.Experimental.Rendering.HDPipeline;
7. using UnityEditor.VFX.UI;
8.  
9. public class particleMainScript : MonoBehaviour
10.  
11. {
12.     UnityEngine.Experimental.VFX.VisualEffect visualEffect;
13.     float exposedParameter;
14.     void Start()
15.     {
16.         visualEffect = this.GetComponent<UnityEngine.Experimental.VFX.VisualEffect>();
17.         // exposedParameter = visualEffect. -> what to insert here to access the expoosed parameter?
18.     }
19.     void Update()
20.     {
21.         if (Input.GetKey("down")){
22.             visualEffect.Stop();
23.         }
24.         else
25.         {
26.             visualEffect.Play();
27.         }
28.     }
29. }

 

Ok, found it out.

You have to write:

Code (CSharp):

1. visualEffect.SetFloat("parameter", 0);
2.  

"parameter" is your name of the exposed parameter

 

I love you.

How did you find this out?
