Adding New Block Types To The Block Mining Simulation Game

[00:00:00]So, for today's video, it's finally time to do a little bit of work again on the block mining simulation game. Back about a month ago or so, I had a customer who purchased a few custom block types in my block mining simulation game. And as of today, I have yet to add those. So, I think it's finally time to fulfill the customer's request. And in addition, I also have a little bit of work that I did when I was still back in Ontario that is currently not merged into the public branch. So, I'll also do that today. And since I haven't worked on this project or thought about it at all in a couple months now, this will also be a good refresher for me. And looking over these commits now, I completely forgot what I was planning to do next.

[00:00:39]So, I got those changes merged in. And it looks like the last thing that I was working on was this uh debug user interface for testing my uh generic scroll bar user interface feature. So the idea here is that scroll bars are a uh very common user interface feature and I want to make it so that I can implement the scroll bar feature once uh and then just kind of generically inherit this in a number of classes and get that behavior automatically as long as I specify um the width and the height of the object and have some kind of callback for what happens when you actually trigger a scroll event. So, here are the new custom block types that were purchased by the customer. And here is my ad hoc list of names and values that I keep around in a text file. And so, I'll just uh take these pieces of information and manually add those to the source code of the game. And it is on my to-do list to come up with a automated process for adding these new block types. But so far, I haven't actually had to add enough of these manually yet to justify automating the entire process. Okay, so those new block types have now been added to the manifest file. Now I just have to add them to the help menu and also to the chunk initializer code so that they actually uh spawn and show up in the world. And for reference, this is currently where that manifest file that I was just editing is stored. Okay, now we'll edit the block skins file so that these blocks will actually show up in the world and in the help menu. So I have added these four lines to the block skins class and this defines how to map those classes to uh actual characters that get displayed on screen. And those unic code characters there are different than the ones that I listed before because I actually forgot that in Java strings you have to use the uh two byte surrogate pairs for the more wide emoji characters. And down just a little bit in the same file, I have added these four lines. And these lines will control what shows up in the help menu for the description for these block types. And now we'll edit this file, which controls which block types show up in the world.

[00:02:44]Okay, those four lines there should make it so that those new block types actually spawn into the world now. And it looks like I forgot to create the underlying class type for each block type. And at the moment, these individual block type classes are basically just placeholders and they're pretty much all identical and just copied and pasted. Okay, this time it actually worked perfectly and compiled except for one small little thing where um this unicode character I actually got the value that's commented out there from Google's AI overview and uh apparently it's uh not correct. It shows up as an invalid unicode character on my machine. And here are the four new custom block types showing up in the help menu. So the next thing that we have to do is play the game a little bit and make sure that those blocks actually spawn in the world and that you can mine them. Okay, so I think we've successfully mined everything. We've got some azurite and we've got some coupite and borite and some dioptase. So I think that's good to merge into the master branch and push that publicly. Okay. And those changes have now been pushed publicly. And that's how you add a new block type to the block mining simulation game.
