The known issues are:
This is not a full game. It was never designed to be. This is meant to be a some what complete inventory system for exiting or new projects. I had to draw a line at some point in order to focus on what I was trying to achieve.
The line I choose was the point at which the code path starts to branch to other areas. Such as animation, physics, FX, audio, story exc. When I reach that point I try to decouple that code and put it in the 'demo' area. This can leave the demo feeling unfinished. For example in the demo at time of writing when an item is selected it does not appear in the the characters hand. The where's and how's of how to attach the weapon or tool to your players avatar are myriad. its not practical to code for all of them. So I leave the code open for you the developer to continue as makes sense for the project at hand.
That said there are still some issues that I know of and hope to fix soon.
Mining. It's does what it says on the box. However its a bit janky due to the way I have tied it to the animations. its at that point where it's crossing the line of what is and isn't part if the inventory system. I believe I can rain it in eventually.
Documentation: It does exist. I am the only person working on this and that's the boring part game dev. Plus I kept changing things so much it was hard to keep track. So I end up just adding comments to the code to explain everything. I promise I will work on some guides and videos to show you how to deploy this.
Dropped object TTL and durability. Durability kind of got forgotten about a while ago. I could not work out how to make it consistent and persistent when items where being moved around, used, dropped and picked up. I have since worked this out and this issue should 'fade' away as I go through the item catalogs and code to apply the update.
Hopefully there are no more major issues to be found. If you do find any issues please let me know and I will address them as soon as possible.
