This is the last tutorial on using the UIToolkit as Unity as announced the new GUI coming this year. I do not want to create my GUIs with this system, and then have to spend more time later on down the road redoing them when Unity comes out with their system. So I will wait and see when Unity comes out with it, what one I like better and use it. So in this video, I am just going to finish up adding the event for the inventory slots, and show how we can get a unique identifier for what button was pressed. If you wish to continue using the UIToolkit, this should be enough to get you going on implementing it in to the game. I am going to include the scripts in a folder along with the download for the people that have purchased the scripts, but keep in mind that I am not going to be doing any further development with them until I see what Unity has to off.
