@Baconman321 World generation is great! Just need to fix the fact that you can walk through half slabs. Also, it may be a good idea to draw text to the canvas instead of in HTML elements because it's faster. Or at least disable highlighting for a better user experience. Just add another canvas right on top of the other one. All of the DOM events will go right through to the lower canvas. And what 3D rendering library are you using? I am using ThreeJS.
@Battledash2 Read 5 minutes of this and you will immediately change your mind. CSS transformations are way to laggy to do anything, there are way less resources than WebGL, and it is a lot harder to make a game with it. Here is a simple version of Minecraft that I made using ThreeJS and here is something to help with animations.
I am planning on making my own multiplayer game and have a question;
are you handling user input client-side or server-side? When a player presses "W" for example, is it processed on their computer, or is it sent to the server for processing?
@JULIODIAZ1 Usually seeds are only used to create worlds, not the other way around. Think of seeds like a hashing algorithm, they can not be reversed. Also, I don't think there is any way to store 3 dimensional block positions in any better overall way than 3 dimensional arrays. Some may be more efficient, but the current way can be used easier in most cases.
