iTween: How to animate other shader-color values besides the main Color?


is it possible with iTween to tween other Shader-color values like "_SpecColor" or "_ReflectColor" or any custom shader values? The current tween parameters like "ColorFrom/ColorTo/ColorUpdate" only edit the MainColor..

For example i use Ani.Mate for tweening like this (but would love to use iTween only):

 meshArray.renderer.sharedMaterial.SetColor("_SpecColor", Color.red);

Thanks for any help on that.

I don't know if this is still needed, but I've searched in many places and didn't find an answer.

You need to change the iTweenScript to be able to handle this. Is a small change, just add "_TintColor" to the NamedValueColor enum. It should be like this:

 public enum NamedValueColor{
         /// <summary>
         /// The main color of a material. Used by default and not required for Color methods to work in iTween.
         /// </summary>
         /// <summary>
         /// The specular color of a material (used in specular/glossy/vertexlit shaders).
         /// </summary>
         /// <summary>
         /// The emissive color of a material (used in vertexlit shaders).
         /// </summary>
         /// <summary>
         /// The reflection color of the material (used in reflective shaders).
         /// </summary>

After that, just use ColorTo normally:

 iTween.ColorTo(gameObject,{"a": 0.3,"time":1,"namedcolorvalue": "_TintColor", "loopType":"pingPong", "easeType":"easeInOutQuad", "includeChildren":true});

I've forgot to remember you, you need to change "_TintColor" for whenever value you like!

Hey everyone, thanks in advance for all the help.

This seems to address exactly what I am having trouble with, the only issue is that I am using the iTween Visual Editor and am not able to use ColorTo as referenced above. Im not a programmer, so the Visual Editor has been great for creating all the animated color shifts, I just cant get it to change my particle colors.

Do you know how I can add _TintColor to the iTweenEvent script so that I can change the Tint Color of Particles using the iTween Visual Editor rather than calling it from a script? Ive been digging around in all the iTween scripts to no avail.

Thanks, Austinj

Thank you thank you thank you tiagomelobr. That's exactly what I needed (modifying the NamedValueColor enum).
