The type or namespace 'blabla' could not be found

Hello everyone !

I was making a camera script (2018.2.0f2). When i made a unity update (2018.3.1f1), the script has now errors like : the type or namespace ‘PropretyDrawer’ and ‘SerializedProprety’ could not be found.

Here’s my script :

 using UnityEngine;
 using UnityEditor;
 using System.Collections.Generic;
 
 
 
 [CustomPropertyDrawer(typeof(TagSelectorAttribute))]
 public class TagSelectorPropertyDrawer : PropertyDrawer
 {
 
     public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
     {
         if (property.propertyType == SerializedPropertyType.String)
         {
             EditorGUI.BeginProperty(position, label, property);
 
             var attrib = this.attribute as TagSelectorAttribute;
 
             if (attrib.UseDefaultTagFieldDrawer)
             {
                 property.stringValue = EditorGUI.TagField(position, label, property.stringValue);
             }
             else
             {
                 //generate the taglist + custom tags
                 List<string> tagList = new List<string>();
                 tagList.Add("<NoTag>");
                 tagList.AddRange(UnityEditorInternal.InternalEditorUtility.tags);
                 string propertyString = property.stringValue;
                 int index = -1;
                 if(propertyString =="")
                 {
                     //The tag is empty
                     index = 0; //first index is the special <notag> entry
                 }
                 else
                 {
                     //check if there is an entry that matches the entry and get the index
                     //we skip index 0 as that is a special custom case
                     for (int i = 1; i < tagList.Count; i++)
                     {
                         if (tagList *== propertyString)*

{
index = i;
break;
}
}
}

//Draw the popup box with the current selected index
index = EditorGUI.Popup(position, label.text, index, tagList.ToArray());

//Adjust the actual string value of the property based on the selection
if(index==0)
{
property.stringValue = “”;
}
else if (index >= 1)
{
property.stringValue = tagList[index];
}
else
{
property.stringValue = “”;
}
}

EditorGUI.EndProperty();
}
else
{
EditorGUI.PropertyField(position, property, label);
}
}
}
Can someone help me ?
Thanks

This is not a camera script but an editor script. It has to be placed in an editor folder. You probably have it outside an editor folder.
