An updated documentation would be nice. The 4.9 video suggests only a few steps are needed to get it to work, but the example file characters have way more things going on. Also a chain of instructional videos that forward you to another video a minute is confusing. There should be one written or video instruction that fits the actual version that is available. Now I would like to know if
a. something went wrong while I was following this tutorial: https://.youtube.com/watch?v=XtHvfT9oZxU
b. I still have to transfer the existing code that looks important from the fps character to mine, from the example files
c. Or whether that video only is supposed to make the basic inventory screen work, without the item interaction
