Assigning properties (via enums) to an array value

Hi All

I have a camera manager script that is just a simple public array that functions as per normal - I type in the size of the array in the inspector, then I can drag and drop the camera objects to the list.

However, is it possible to somehow introduce an enum dropdown to each of these cameras?

So, the workflow would be I type in how many cameras (the size of the array) into the inspector, then I drag and drop the cameras, and then each camera in the inspector also has a dropdown where I can specify an additional property per camera.

My simple knowledge of scripting tells me this isn't really possible in a simple way like I envisage, however i'd like to hear some thoughts about possible ways this could be implemented - I'm not asking for code, just general guidance so I can figure it out for myself.

Thanks

 

Try to use an array of class.

 

It sounds like you are after something like this:

Code (csharp):

1.  
2. // Assets/CameraEntry.cs
3. using UnityEngine;
4.  
5. public enum YourEnum {
6.     A,
7.     B,
8.     C
9. }
10.  
11. [System.Serializable]
12. public sealed class CameraEntry {
13.     public Camera camera;
14.     public YourEnum yourEnum;
15. }
16.  
17. // Assets/YourBehaviour.cs
18. using UnityEngine;
19. using System.Collections.Generic;
20.  
21. public class YourBehaviour : MonoBehaviour {
22.     public List<CameraEntry> entries = new List<CameraEntry>();
23. }
24.  

The default inspector requires that you expand items in order to specify camera and your enum value, but you could create a custom property drawer for a more appropriate inspector interface:

Code (csharp):

1.  
2. // Assets/Editor/CameraEntryPropertyDrawer.cs
3. using UnityEngine;
4. using UnityEditor;
5.  
6. [CustomPropertyDrawer(typeof(CameraEntry))]
7. public class CameraEntryPropertyDrawer : PropertyDrawer {
8.     public override void OnGUI(Rect position, SerializedProperty property, GUIContent label) {
9.         var propCamera = property.FindProperty("camera");
10.         var propYourEnum = property.FindProperty("yourEnum");
11.  
12.         // Draw camera field.
13.         position.width /= 2;
14.         EditorGUI.PropertyField(position, propCamera, GUIContent.none);
15.  
16.         // Draw enum field.
17.         position.x = position.xMax;
18.         EditorGUI.PropertyField(position, propYourEnum, GUIContent.none);
19.     }
20. }
21.  

If you want your list to be reorderable then you might want to consider using our open source control:

Disclaimer: None of the above has been tested, but hopefully it will help. Let me know if you have any trouble with these snippets and I will take a closer look for you

 

Thanks, I'll check that out.

 

Thanks a lot numberkruncher, you've given me a lot to digest and learn! Much appreciated.
