How do you get the Minecraft code?

I would like to rewrite something in Minecraft code, how do I get it?

Not at all, because Minecraft is not open source.

You can "change" the code via detours. However, where change is the wrong word.

The detours would be mods. You can write your own mods with the help of libraries. Simply go to the Internet afterwards 😉

What exactly do you want to change? If necessary, someone can help you directly with what you want to do.

Which version?

With MCP (Mod Coder Pack) you can get the source code and edit it.

For newer versions there's MCP Reborn from Hexeption:

And do you think hacked clients don't exist? XD

Thanks!
