JavaScript => public function GetProceduralPropertyDescriptions(): ProceduralPropertyDescription[];
C# => public ProceduralPropertyDescription[] GetProceduralPropertyDescriptions();

Description 描述

Get an array of descriptions of all the ProceduralProperties this ProceduralMaterial has.

获取这个程序材质所有属性描述的一个数组。

This can be used to build generic GUI that can be used to edit the properties of any ProceduralMaterial without knowing its properties in advance.

这可以用来构建泛型GUI，能用来编辑任意程序材质的属性，而事先不知道它的属性。

JavaScript:

var scrolling : Vector2;
var rend: Renderer;
 
 
function Start() {
	rend = GetComponent.<Renderer>();
}
 
 
function OnGUI () {
	if (rend.sharedMaterial as ProceduralMaterial) {
		// Show substance properties inside window
		var windowRect = new Rect (Screen.width-250, 30, 220, Screen.height-60);
		GUI.Window (0, windowRect, ProceduralPropertiesGUI, "Procedural Properties");
	}
}
 
 
function ProceduralPropertiesGUI (windowId : int) {	
	scrolling = GUILayout.BeginScrollView (scrolling);
 
	var substance = rend.sharedMaterial as ProceduralMaterial;
 
	// Get a list of all the Procedural properties
	var inputs = substance.GetProceduralPropertyDescriptions ();
 
	// Iterate through all the properties
	for (var i : int = 0; i < inputs.Length; i++) {
		var input = inputs[i];
 
		// Handle the different types of properties
		var type = input.type;
 
		// Show a boolean as a toggle
		if (type == ProceduralPropertyType.Boolean) {

			var oldInputBool = inputBool;

			var colorComponentAmount = (type == ProceduralPropertyType.Color3 ? 3 : 4);

				colorInput[d] = GUILayout.HorizontalSlider (colorInput[d], 0, 1);
