That's what I meant to do when I said I wanted to try Minecraft modding. A lot of (almost all) tutorials are about how to add new blocks, and new items to the game, where I just want to "simply" change the internal logic of the game (the existing content).
But it turns out that I have to know the game's internal beforehand, which is not easy. I'm still reading Mojang's spaghetti. And thanks to the decompiler, it names the variables in i,j,k, etc.
Do we have something like ghidra for Java bytecode?
