    I'd like to be able to create a slider for controlling variables in the editor - like the specular value on glossy shaders. Using the method that's in the shader source doesn't seem to work in js. How would I go about this?

    Thanks!

    This should do what you want:

    Code (csharp):
    1. //keep our own copy of shininess so we aren't always reading from the material
    2. private var shininess : float;
    3.  
    4. function Awake() {
    5.     //initialize shininess from material
    6.     shininess = renderer.material.GetFloat("_Shininess");
    7. }
    8.  
    9. function OnGUI() {
    10.     //get a new shininess out of a slider
    11.     shininess = GUI.HorizontalSlider(new Rect(10, 10, 100, 20), shininess, 0.01, 1.0);
    12.     //assign the shininess to the material
    13.     renderer.material.SetFloat( "_Shininess", shininess );
    14. }

    Ah, looking at my post I could have been more clear - what I'd like to achieve is a slider in the inspector (supplanting type fields), rather than a GUI solution.

    You'd nee to create your own custom inspector for that (that is, extend the editor rather than setting up parameters on your game object).

    This is possible in 2.1, however since custom inspectors are not officially supported, your code might very well break after the next release of unity.
