How to display GUI components like UnityEvent, Color Gradient etc. for Custom Inspector?

Hi guys,

While it's very easy to get UnityEvent or Gradient variables being displayed in inspectors for MonoDevelop scripts, it's quite hard to get it on the custom inspector without using base.OnInspectorGUI (which is not what I want).

Any ideas?

Thanks in advance!

 

EditorGUI.PropertyField (or EditorGUILayout.PropertyField).

Code (csharp):

1. public MyScript : MonoBehaviour {
2.     Color myColor;
3. }

Code (csharp):

1. [CustomEditor(typeof(MyScript))]
2. public class MyScriptEditor : Editor {
3.     public override void OnInspectorGUI() {
4.         EditorGUILayout.PropertyField(serializedObject.FindProperty("myColor"));
5.     }
6. }

 

Thanks! However, I have the following problem.

I have a list within a list with a custom defined class. So it goes like this:

LIST1:
- Variable 1
- Variable 2
- LIST2:
- Variable 3
- GradientVar

Variable properties are based on those two LISTS' index number, so the variable itself doesn't remain the same, it's value always changes.

How do I get Gradient Variable 1 be edited by the PropertyField? I tried doing something like this:

Code (CSharp):

1. EditorGUILayout.PropertyField("LIST1[indexNumber].LIST2[indexNumber].GradientVar");

And obviously, it didn't work.

Thanks in advance

 

A SerializedProperty (as returned by serializedObject.FindProperty) can represent an array such as your LIST1. To iterate through it, use GetEnumerator() and MoveNext(). There's a good explanation with code examples on Hamaluik.com.

However, maybe it would be easier to just use property attributes in your MonoBehaviour definition and forgo the custom inspector. Something like:

Code (csharp):

1. [Serializable]
2. public MyGradientData {
3.     public bool variable3;
4.  
5.     [CustomGradient]
6.     public Gradient gradientVar;
7. }
8.  
9. [Serializable]
10. public MyMainData {
11.     public bool variable1;
12.     public bool variable2;
13.     public MyGradientData[] list2;
14. }
15.  
16. public MyScript : MonoBehaviour {
17.     public MyMainData[] list1;
18. }

You'd need to define the custom property attribute "CustomGradient" as described in the Property Drawers manual section.
