Public Variables Not Displaying In The Inspector

Hi, The error is telling you that the class either does not derive from MonoBehaviour or the name of the class is not the same as the file name. So your public variables aon't show unless the two above conditions are met. ie:

     // this class is derived from (is a sub class of) MonoBehaviour
     // Unity needs this for a class to be added to a GameObject
     public class MyScriptClass : MonoBehaviour
     {
         public string myVariable = "My Variable";
     }
 
     // the above code should also be contained in a file called MyScriptClass.cs
