I am also sorry to state that 1.4 will be the last 1.7.10 update for this mod. 1.7 has had a great run, but I need 1.8 for certain features to work, plus tutorials for 1.7 are diminishing in number (from being "updated").
Things so far have been good. Post 1.8 actually made some things easy, such as rotation.
As for inventories, I have no clue whether or not I can get them working. Basically, I am working off of pure deduction, as I can no longer find ANY info beyond the basics, blocks, items, etc., as any 'advanced modding' is pre-1.8, which is basically becoming irrelevant to me. I think I can succeed, but don't hold your breath.
Note: Some current blocks will NOT be compatible with the new ones, as the TileEntities are changing. I may also be moving this over to the completed mods, as inventories are the ONLY thing holding me back.
Although this reply is somewhat late, due to me not hovering around here like I used to, I figured I might as well say it.
In reality, I stopped updating this mod for three reasons: Life, Plagiarism, and Convenience.
On the convenience side of things, I basically had no idea what I was doing. Essentially, I was looking at other people's code to see how they did something, like inventories, and making my own spin on that. There aren't too many tutorials that go in-depth about the more complex Minecraft things -I remember how it took me months to figure out how to properly rotate a block- and I really hated being forced to look at the source code just to do simple things. Since I was still in school, I didn't have much spare time to take Java lessons; and in all honesty, I hate the language anyways. And no, I'm not a C++ advocate. I also hate C++.
Then there was plagiarism. I don't know if it was honestly him/her stealing my ideas or not, but a certain someone who's mod is more popular than mine kept adding features to his mod that I was going to add to mine. That got real old real fast after he added a fish tank.
And then life. About two years before I graduated, I realized that I was wasting my time playing Minecraft instead of more productive things. I had been playing on my favorite server, "Happy Valley", and I was basically the only one there 90% of the time, until one day I remembered what my father said about people he knew wasting their lives on games. I then decided I needed to change, and I swapped over to watching anime as my main hobby. I figured I was better off with something I get tired of more easily than focusing on the more-addictive sandbox game.
And that's pretty much it. I honestly don't think I'll be updating this mod until such a time as I have nothing more productive to do. You may see a 1.24 version, but don't hold your breath.
