Simple Editor Script

Does anyone know how I can execute the AddWaypoint() from line 37 in the PathTool script? I can execute the CreateNewPath() on line 14 easily. But can't figure out how to execute from inside the OnScene() method.

My spawner script:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class Spawner : MonoBehaviour
4. {
5.     public void CreateNewPath() { // Do stuff }
6.  
7.     public void AddWaypoint(Vector3 position, Quaternion rotation) { // Do more stuff }
8. }

My editor script to add 2 buttons to my spawner script:

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3.  
4. [CustomEditor(typeof(Spawner))]
5. public class PathTool : Editor
6. {
7.     public override void OnInspectorGUI()
8.     {
9.         DrawDefaultInspector();
10.         Spawner spawner = (Spawner)target;
11.  
12.         if (GUILayout.Button("Create New Path"))
13.         {
14.             spawner.CreateNewPath();
15.  
16.             SceneView.duringSceneGui -= OnScene;
17.             SceneView.duringSceneGui += OnScene;
18.         }
19.  
20.         if (GUILayout.Button("Finish Adding Waypoints"))
21.         {
22.             SceneView.duringSceneGui -= OnScene;
23.         }
24.     }
25.  
26.     private static void OnScene(SceneView sceneview)
27.     {
28.         HandleUtility.AddDefaultControl(GUIUtility.GetControlID(FocusType.Passive));
29.         if (Event.current.type == EventType.MouseDown)
30.         {
31.             Vector2 mousePosition = Event.current.mousePosition;
32.             Ray ray = HandleUtility.GUIPointToWorldRay(mousePosition);
33.  
34.             RaycastHit hit;
35.             if (Physics.Raycast(ray, out hit, 10000f))
36.             {
37.                 // How to reach AddWaypoint() from here?
38.             }
39.         }
40.     }
41. }

 

You can use Static variable to do that, just store the spawner in a static variable, something like this:

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. [CustomEditor(typeof(Spawner))]
4. public class PathTool : Editor
5. {
6.    
7.     private static Spawner spawner;
8.    
9.     public override void OnInspectorGUI()
10.     {
11.         DrawDefaultInspector();
12.         spawner = (Spawner)target;
13.         if (GUILayout.Button("Create New Path"))
14.         {
15.             spawner.CreateNewPath();
16.             SceneView.duringSceneGui -= OnScene;
17.             SceneView.duringSceneGui += OnScene;
18.         }
19.         if (GUILayout.Button("Finish Adding Waypoints"))
20.         {
21.             SceneView.duringSceneGui -= OnScene;
22.         }
23.     }
24.     private static void OnScene(SceneView sceneview)
25.     {
26.         HandleUtility.AddDefaultControl(GUIUtility.GetControlID(FocusType.Passive));
27.         if (Event.current.type == EventType.MouseDown)
28.         {
29.             Vector2 mousePosition = Event.current.mousePosition;
30.             Ray ray = HandleUtility.GUIPointToWorldRay(mousePosition);
31.             RaycastHit hit;
32.             if (Physics.Raycast(ray, out hit, 10000f))
33.             {
34.                 // How to reach AddWaypoint() from here?
35.                 // Here is how to reach AddWaypoint()
36.                 if (spawner != null) {
37.                     // Here you have full access to Spawner methods and properties.
38.                 }
39.             }
40.         }
41.     }
42.    
43. }

Hope this helps.
Regards.

 

Perfect thanks. It worked!
