The CinemachineImpulseDefinition can not work for private field with SerializeField.

I use the CinemachineImpulseDefinition in my own script to simulate the camera shake.
I write it like this:

Code (CSharp):

1.  
2. [SerializeField]
3. [CinemachineImpulseDefinitionProperty]
4. public CinemachineImpulseDefinition impulseDefinition =
5.     new CinemachineImpulseDefinition();
6.  

I want to change the public to private, because there is no need to access the impulseDefinition outside, but the editor inspector show a lot of error when I switch to private field.

I see the EmbeddedAssetPropertyDrawer.cs may not support the private field:

Code (CSharp):

1.  
2. Type EmbeddedAssetType(SerializedProperty property)
3. {
4.     Type type = property.serializedObject.targetObject.GetType();
5.     var a = property.propertyPath.Split('.');
6.     for (int i = 0; i < a.Length; ++i)
7.         type = type.GetField(a[i]).FieldType;
8.         return type;
9. }
10.  

It use GetField but it may not work with private field.
