access a shader property from C#

Hey guys,

can anyone tell me how i can access these from C#?:

Code (csharp):

1. Properties {
2.         _Seed ("Seed", Range(0.0,1.0)) = 0.5
3.        
4.         _NoiseScale1 ("Noise Scale", Float) = 1
5.         _NoiseTexture1 ("Noise Texture", 2D) = "white" {}
6.         _RampTexture ("Ramp Texture", 2D) = "white" {}
7.         _BandFilter ("Band Filter", Range(0.0,1.0)) = 0.5
8.         _BandWidth ("Band Width", Range(0.0,1.0)) = 0.5
9. }

I want to access the "Seed" properties 'n such.
any hints are welcome.

thanks

 

You do that through the GetXXX functions of the Material class ( http://unity3d.com/support/documentation/ScriptReference/Material.html ) in this case GetFloat

 

Code (csharp):

1. Debug.Log(planet.renderer.material.GetFloat("Seed"));

returns an error, even if i log HasProperty("Seed") i get false, for some wierd reason,

but if i log planet.renderer.material.name, i get the right name of the shader.
Any ideas?

 

what about _Seed?

 

arghs - thank you

 

hahaha that was funny

 

logged in just say that was funny and thanks for the answer too

 

SOLVED - See next post..

Hi All, struggling a little with updating the "Clip" value at run time.

I am trying to change clip value over time, however i am not getting any issues except the clip value never changes.
i watch the debug of the float change fine as expected, but not updating the shader.

for sure i am doing something wrong, i went to the script reference to re-check that the enum property.clip is correct and it takes a float, and it does, but somehow it is never passed on.

If i manually drag the slider back and forth it does what i expect.

Any ideas.


Screenshot:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using AmazingAssets.AdvancedDissolve;
5. using UnityEngine.Rendering;
6.  
7. public class DissolveThisStuff : MonoBehaviour
8. {
9.     private float time;
10.     public float targetTimeDissolve = 10f;
11.     public float targetValue = 1f;
12.     private Material LocalMaterial;
13.  
14.  
15.     private void OnEnable()
16.     {
17.         LocalMaterial = GetComponent<Material>();
18.         AdvancedDissolveKeywords.SetKeyword(LocalMaterial, AdvancedDissolveKeywords.CutoutStandardSource.TwoCustomMaps, true);
19.     }
20.  
21.     private void Update()
22.     {
23.         time += Time.deltaTime;
24.         float value = Mathf.Lerp(0, targetValue, time / targetTimeDissolve);
25.         Debug.Log(value);
26.  
27.         AdvancedDissolveProperties.Cutout.Standard.UpdateLocalProperty(
28.             LocalMaterial,
29.             AdvancedDissolveProperties.Cutout.Standard.Property.Clip,
30.             value);    
31.     }
32.  
33. }

 

Okey... UPDATE.. got it working as i wanted to..

Changed script from above..

17.     {
18.         thisRender = GetComponent<Renderer>();
19.         LocalMaterial = thisRender.material;
20.     }

22.     private void Update()
23.     {
24.         time += Time.deltaTime;
25.         float value = Mathf.Lerp(0, targetValue, time / targetTimeDissolve);

29.             LocalMaterial,
30.             AdvancedDissolveProperties.Cutout.Standard.Property.Clip,
31.             value);    
32.     }
