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.

i cannot get over the fact that at some point anyone may have interacted with a mob named FatSnail

1:53 "nearly unplayable" I play with that kind of lag daily

That poor villager at 14:20 is getting an autopsy while he's still alive....

In most video games, seeing these sort of debug tools is normal. I never once thought about Minecraft having them for some reason but there is something special about seeing it done in Minecraft. It's like the inner workings of my favorite video game have always been a secret up until now. Super cool! Thank you!

a couple months ago while poking around with modding i ran into the disabled debug renderers! i had thought to myself "this would make a really good video", but never ended up making it. this goes above and beyond, i love all the information in this. i am simply fascinated :O

9:27 This is not a discontinued feature. It's simply not shipped.
They use ProGuard, which will strip out unused code. That code is probably controlled by a value in the constants file.
ProGuard will see that this code can never run since nothing can change that variable (except someone modifying the code), so it removes it.

Game tests, not unit tests - these are way too interconnected to be considered units. Good work piecing stuff together!

Your test failed because you tested for the powder snow immediately, and it doesn't appear until the game has actually ticked. Also, seeing game tests written with those mappings is extremely cursed 😄

[JonathanDavidsonn]

Just as aa heads up, the unit test isn't performed by a human, it's often ran automatically when developers submit their work. It's a way to make sure your changes don't break a certain expectation of a unit test.

I just realised something: Almost all new mobs now use the brain system (1.16+ mobs) meanwhile the older ones don't (like the pig or the horse)

The glow squid was added in 1.17 but that is basically a re skin of the squid (which was added in Minecraft alpha)

This is really interesting! I especially love how the test command utilizes colored beacons to tell you if it was successful as well as "printing" the error message on a lectern. Such an out-of-the-box and hilarious way of displaying that!

I remember that during the last Minecraft Live, they talked about how they created new developer tools to make features. While they didn't specify if they were internal or external, it'd be cool if these were some of them.

Also, it's interesting how all of the mobs with special "brain" AI were introduced starting from 2019.

I love how you can see how the code improved like how a spawner isn‘t a structure but everything else is. Really interesting to see differences between mojangs and microsofts work

[immuno]

I love how when a test passes, there is a little smiley face

huh I didn't know bees followed warrior cat naming conventions :p

You missed one of the more interesting developer commands: /chase. It allows you to sync two or more clients from the same or different machines and when you move on the "lead" client the "following" clients will move the same way. It was added in 1.18 to help test worldgen changes.

22:00 ohh that explains 1 glitch in bedrock were a shipwreck can spawn super high in the air

[NRGJobro]

I have a 1.19.60 dev version of Bedrock edition and it has an Imgui window with 100x more features. It’s got a ton of cool stuff

[wishntt]

i fucking love squares that have eight sides

[theyoutubeplague]

14:43 this villager doesn't remember the last time he slept... same

[Tsunamicat]

This is actually really cool. Im gonna install it so my friends think i’m smart when i randomly turn stuff on and off and see the green boxes
