+====== Result ======
+You have now seen how to transfer data when the ScreenHandler is opened. In the image you can see the result: The Blocks title is now the block position. Do note that this is just a demonstration,
+Setting the position as the title would be possible alot easier.
+You might wonder: Can i transfer this data again even after the Screen was opened?
+This is possible by sending custom Packets (see: [[tutorial:networking|Networking Tutorial]]) after the Screen has been opened. \\
+You might also want to have a look at the BlockEntityClientSerializable Interface from the Fabric API.
+If you only want to sync integer values you can use PropertyDelegates SEE MY NEXT TUTROIAL
