Questions & Answers

I started following this tutorial on youtube and I got to a point where their is just one error from stopping me. Then I researched it a lot of people had this problem but so I found a completed version of the script that was released online I tested it out and I still get the single error.

//my error
Assets/my menu/FOLLOW ME/MYGUI/MyGui.cs(13,22): error CS0246: The type or namespace name `Item’ could not be found. Are you missing a using directive or an assembly reference?

The error is telling you that you don’t have a class called Item anywhere. Your inventory is, essentially, made up of a list of Items, but you haven’t defined what an Item is! (Or at least it hasn’t been defined in this script). :slight_smile: Check and see if there was anything more to the tutorial; you need to have an Item class for this script to work.
