Hi,
I am a bit lost:
I have written a custom editor which draws a serializable property sp, but all values I assign to sp vanish on play. Importantly, the serialized property is drawn with two nested custom property drawers.
- I have added
sp.Update()andsp.ApplyModifiedProperties()before and after modifying the serialized property sp in the editor script - The custom editor script includes
EditorUtility.SetDirty(t)at the end as well asUndo.RecordObject(t, "xxx")on the target object t.
What could go wrong here?
Any help would be very much appreachiated!
The screenshot shows the custon editor. If I click play, the fields “nuts”, “berries” (…) disappear. Anything else that is not part of the seralized property stays.
Code for the custom editor
[CustomEditor(typeof(StimulusManager))]
public class StimulusManagerEditor : Editor
{
void OnEnable()
{
_target = (StimulusManager) target;
_targetSerial = new SerializedObject(target);
}
public override void OnInspectorGUI()
{
// save changes from the editor in the game
_targetSerial.Update();
Undo.RecordObject(_target, "Define stimulus");
// Draw the nested property field
_featuresProperty = _targetSerial.FindProperty("NestedFeatures.Array.data[0]"); //Get the property
EditorGUILayout.PropertyField(_featuresProperty, true); //draw the property
// Keep changes
_targetSerial.ApplyModifiedProperties();
EditorUtility.SetDirty(_target);
EditorApplication.update.Invoke();
}
The custom property drawer is this
using UnityEngine;
using UnityEditor;
[CustomPropertyDrawer (typeof (NestedFeature))]
public class NestedFeatureDrawer : PropertyDrawer
{
public override void OnGUI (Rect position, SerializedProperty property, GUIContent label)
{
SerializedProperty FeaturesProperty = property.FindPropertyRelative("Features");
EditorGUI.BeginProperty(position, label, property);
var indent = EditorGUI.indentLevel; //store old indent
EditorGUI.indentLevel = 0; //new indent
// HERE SOMETHING GOES WRONG, THE CONTENT OF THIS PART VANISHES ON PLAY
for (int j=0; j < FeaturesProperty.arraySize; j++)
{
EditorGUILayout.PropertyField(FeaturesProperty.GetArrayElementAtIndex(j), GUIContent.none, true);
}
EditorGUI.indentLevel = indent; //reset indent
EditorGUI.EndProperty();
}
}
