Minecraft source code download When you download Minecraft, you get its code, obscured and then compiled into Java byte code. It is technically readable if one simply decompresses the game files, but the raw byte code is very difficult to understand.

If you download Forge MDK and follow its instructions, it will decompress and obfuscate most of Minecraft’s code, making it easier to read. This mod is the result of an utterly hard effort by the Coder Pack (MCP) team. You can then browse with your favorite IDE; I have mostly used Eclipse.

Since it’s decompiled, it has relatively few comments (the ones that do exist are added by the deobfuscation process) and is only guaranteed to be functionally equivalent to what the Minecraft developers actually typed out (since the compilation introduced some stylistic Simplified options, and removed ambiguity (class, method, and field names).

In addition, the code you see as part of the Forge MDK includes a number of tweaks, additional methods, etc. created by Forge to make modding easier and more stable.

Is the Minecraft code open source

This is surprisingly not a yes-no question.

The Java version of Minecraft is legally closed-source, and it is obscured before compilation, with all names (methods, classes, etc.) being changed to unusable names that do not provide meaning. Instead of something like Block.getRenderLayer() you can have something like Q.func_12345_a() .

However, the modding community dismantled Minecraft (easy) and created deobfuscation mapping to make it easier to move from obscure names to readable ones (not so easy). So it’s practically open source; With just a little effort you can start reading how the code works.

It’s probably not what the developers actually typed – some changes from the code being compiled and then decompiled – but it’s good enough to work.

This being the case, Microsoft/Mojang recently began releasing official deobfuscation mappings for the Java version. Ironically, the modding community has rejected these, as they come with restrictive legal terms that may affect redistribution of mods, whereas the community’s own ad-hoc mappings do not have that problem.

The Bedrock version of Minecraft is completely closed-source. It’s a lot more difficult to decompile C++ than Java, and nobody with Java really bothered to try to start modding on those versions.

Either way, source visibility should not be confused with a free license. Minecraft is obviously not freely licensed, and most mod developers will stop talking to you if you start talking about cracking or pirating the game instead of just changing things up for fun.

Why does Minecraft run on Java?

Minecraft is written in Java because it began as a toy project by Marcus “Notch” Persson, who loved writing things in Java.

It continued to be written in Java as it was easier than a rewrite and would not be bad on Linux and Mac players.

It eventually found a parallel C++ codebase, the “Bedrock” codebase, to support iOS, and that codebase was used for other console versions and the Windows 10 version, especially since it was legally a separate game.

Could sell DLC. The Java version was originally sold with the promise that its purchase included all future game content, so the Java version could not sell DLC.

Is there a way to get the Minecraft Java edition full source code?

Yes. Get hired by Microsoft/Mojang in a programming role, and I’m sure you’ll have access to the full source code. Otherwise, no, Minecraft is a closed source piece of software.

However, you can get closer. Java is relatively easy to decompile, and then a competent programmer can work their way around the next hurdle, which is obscure before even compiling Minecraft, turning class and member names into meaningless things, hence Block. Is Air Instead of something like you’ you have something like m.func_12345_a.

The modding community has developed a set of mappings to decode useful names, and in recent times Microsoft/Mojang have released an official set of fuzzy mappings – which practically no one uses because they are in the community Mappings come with more legal risks than they do. ,

Download Minecraft, a development kit for a modelloader, and you can get (most) of the game’s code decompiled and deobfuscated. This is sometimes stylistically awkward (because some programming style is lost upon compilation), and the variable names are usually unusable, but you can get close to the full source code.

Oh, a caveat: the Minecraft modding community will almost never help you with attempts to “crack” the game and remove its authentication system and such for piracy purposes.

We stay within the goal of adding and changing the content of the game and the technical challenges surrounding it.

How do you code Minecraft?

Without mods:

You can design computers using redstone including logic gates that allow for some shockingly complex behavior. Programs can be hardcoded into logic gates creating a circuit that does one thing or you can create a dynamically controlled system that will allow you to enter various inputs as a button press.

With mods:

Open Computer and Computercraft are both available to allow programming. Computercraft in particular has some great intermod options, including RadNet. Although I have OpenComputer on my current modpack, I usually use Computercraft.

Computercraft mainly introduces computers and turtles. Computers are stationary and can be connected to peripherals, including screens and modems. Turtles are the real excitement because they are essentially one block big robot.

They can be equipped with any number of diamond tools and can be taught to use them using codes. Their fuel is configurable but is coal or other burnable blocks by default.

In Computercraft you can program using Lua. You can load in programs that you wrote on desktop or type them in using the Dos-like interface.

I still haven’t done everything with this mod because the possibilities are so wide.

You can also program your own mods using existing modding APIs. It requires learning Java and the kinds of things that mods can do in Minecraft. It is also possible to join an existing mod team or to update a dead mod to current versions.

The current version of most mods runs almost a year behind the release, and a large amount of the challenge is about making the mod compatible with other mods.

Hopefully this led to some ideas for programming projects in this huge sandbox game. I love how Minecraft promotes coders and computer science enthusiasts like me so much. There are mods and many small easter eggs within the core game that will inspire users to think like a programmer.
