Serialized script asset turns into blank default asset

Questions & Answers

I’m doing a test to see if I can create an asset instance of a script that I can drag into an object inspector, but afterward it just turns into a blank “default asset”

ScriptableObject script:

public class CF_Constant : ScriptableObject
{
  public Color value = new Color (1f, 1f, 1f, 1f);
  public Color getValue (float t){ return value; }
}

I turn it into an asset using this script:

static void createConstantCF()
{
  CF_Constant c = ScriptableObject.CreateInstance("CF_Constant") as CF_Constant;
  string path = AssetDatabase.GenerateUniqueAssetPath("Assets/New Constant CF");
  AssetDatabase.CreateAsset(c, path);
  AssetDatabase.SaveAssets();
  EditorUtility.FocusProjectWindow();
  Selection.activeObject = c;
}

and have a custom inspector for it:

public override void OnInspectorGUI()
{
  CF_Constant _target = target as CF_Constant;
  _target.value = EditorGUILayout.ColorField("Color", _target.value);
}

This works and shows a “CF_Constant (Script)” in the inspector with the custom inspector showing the color property.

The problem is, as soon as I click on anything else, even if I click the newly created asset, it turns into a blank “default asset” and it could not be dragged into a

_target.customColor = EditorGUILayout.ObjectField("Color", _target.customColor, typeof(CF_Constant)) as CF_Constant;

inspector code.

Am I missing something? Or is this just not possible to do?
I’m using Unity 3.3 for a test bed.

Problem solved.
The extension of the asset need to be .asset.

string path = AssetDatabase.GenerateUniqueAssetPath("Assets/New Constant CF.asset");
