Editor.CreateEditor

Parameters

Description

Make a custom editor for targetObject or targetObjects.

By default an appropriate editor is chosen that has a matching CustomEditor attribute. If an editorType is specified, an editor of that type is created instead. Use this if you have created multiple custom editors where each editor shows different properties of the object. Returns NULL if objects are of different types or if no approprate editor was found.

Consider a script WaypointPathEditor for editing the Transforms of a wayPoint array.

import System.Linq;

@CustomEditor (WaypointPath)
class WaypointPathEditor extends Editor {
	
	var currentTransformEditor;
	var waypoints : Transform[];
	var selectedTransform :Transform;
	var optionsList : String[];
	var index = 0;
	var myWayPath : WaypointPath; 

	function GetWaypoints () {
		var myWayPath = target as WaypointPath;
		
		// Gets only the valid objects from WaypointPath
		if (myWayPath.wayPointArray != null) {
			waypoints = myWayPath.wayPointArray.Where (function(obj) { return obj != null; }).ToArray ();
			optionsList = waypoints.Select (function(obj, index){index.ToString () + ". " + obj.name;}).ToArray ();	
		}	
	}
	
	function OnInspectorGUI () {
		GetWaypoints ();
		DrawDefaultInspector ();
		EditorGUILayout.Space ();
		EditorGUI.BeginChangeCheck ();
		
		if (optionsList != null)
			index = EditorGUILayout.Popup ("Select Waypoint", index, optionsList);
		
		if (EditorGUI.EndChangeCheck ()) {
			var tmpEditor;
			if (index < waypoints.Length) {
				selectedTransform = waypoints[index];

				//Creates an Editor for selected Component from a Popup
				tmpEditor = Editor.CreateEditor (selectedTransform);
			} else {
				selectedTransform = null;
			}
			
			// If there isn't a Transform currently selected then destroy the existing editor
			if (currentTransformEditor != null) {
				DestroyImmediate (currentTransformEditor);
			}
			
			currentTransformEditor = tmpEditor;
		}

		//Shows the created Editor beneath CustomEditor
		if (currentTransformEditor != null && selectedTransform != null) {
			currentTransformEditor.OnInspectorGUI ();
		}
	}
}

And the script attached to a waypath GameObject:

//WaypointPath.js
// This is not an editor script.
var wayPointArray : Transform[];
