What Minecraft Looks Like for a Mojang Dev

These secret Minecraft features for Mojang developers are so secret that I had to make a mod to enable them. I do not work at Mojang nor am I affiliated with them.

  1. I recall watching a talk by a Minecraft developer where they described some of the rendering optimizations. One of the optimizations they made was to precalculate what sides of a chunk section have a line of sight into the neighboring chunk section. That way they can cull any chunk sections that don't have a clear path from where the player is at. Presumably the F3-E SectionPaths and F3-V SectionVisibility is for debugging that.

  2. oh my god. are you serious? the reason my game lags as if i were playing online in singleplay, is because the game is literally simulating an online connection while not being online? id assume any desyncs caused by frame lag caused by memory overload are what causes that, considering how memory intensive minecraft gets. it literally lags and "loses packets" from itself. wow

  3. 4:15 Hey Minecraft bedrock edition actually has that test command without enabling developer hidden stuff how I found it is I was just testing some commands and found gametest that does the same as that command

  4. For those wondering, "Smart Cull" is the game only rendering blocks that you can see, and even on those, only the faces of the block you can see. Turning it off impacts performance because now it's rendering EVERYTHING

  5. 4:20, it's not so of unit tests, more of integration tests, units are for literally one feature, so for example block of grass and what it can do, not piston + grass

  6. a while back before hardcore was in bedrock, texture pack creators could turn on a button on the gui that would allow you to play in hardcore.
