[Free Release][Open Source] PojavLauncher - Minecraft: Java Edition launcher for iOS

2 weeks ago, I got Minecraft: Java Edition works on my iPhone. Now I finished this with all of necessary features:

  • Login with Mojang (might not work), Microsoft (not tested) or offline.
  • Minecraft 1.14+ are playable.
  • Multiplayer and joining servers works.
  • Audio works (need enable ringer).
  • Bedrock-like gestures: click to hotbar slot to switch to; click to place block (trigger right mouse); hold and move to destroy blocks (trigger hold left mouse), but attacking entites is left mouse, so not same as Bedrock.
  • Hold screen on UI will hold the left mouse, so it can also used for moving the scroll bar.
  • On-screen control buttons.
    Also, Fabric and OptiFine works.

Some known limitations:

  • Forge and Fabric API won't work, possibility caused by unsupported Java version 16.
  • Hotbar might not work on some devices(?).

Not tested:

  • Microsoft login.
  • Realms was not tested.

Get v1.0 release here.
Source code: https://github.com/PojavLauncherTeam/PojavLauncher_iOS

Also, I might considering put this up on a repository.
Big thanks to u/T0XicGreif3r - Procursus, who ported OpenJDK to iOS to make this possible and contributors of this project.

UPDATE: Here is instruction installing Fabric and Sodium, OptiFine.

EDIT: a typo; fix text formatting

Supercharge your FPS in Minecraft Java (OpenGL) by replacing the garbage renderer with Sodium or Optifine. 37 fps -> Over 600 fps @ 3440x1440 with 32 Chunks.

I made a post the other day about Optifine and mentioned Sodium in it. However that was before I knew there was a more experimental version of Sodium which runs way better.

Here was my original testing:

16 Chunks Default ~141fps

32 Chunks Default ~37fps

26 Chunks Optifine ~382fps

32 Chunks Optifine ~252fps

40 Chunks Optifine ~140fps

I also did some tests with Sodium 0.1.0 which while better than native were far behind Optifine

16 Chunks Sodium ~219fps

26 Chunks Sodium ~99fps

32 Chunks Sodium ~69fps

A few people in the comments mentioned the new version of Sodium with its OpenGL 4.3 renderer was much better, and /u/pajicadvance23 linked me to a compiled version of it on github here. You'll also need to install fabric and you might want to install fabric api as well.

It runs much better after you set the settings to use the 4.3 renderer

16 Chunks Sodium 4.3 - Over 900 fps

26 Chunks Sodium 4.3 - Over 700 fps

32 Chunks Sodium 4.3 - Over 600 fps

32 Chunks Sodium 3.0 - ~69fps -- Just for reference its still same as previous 0.1.0 build

Now you can see that my GPU is still not being fully utilized, but its clear that there are major issues with Minecraft's code code, which is often called out by developers when looking at some other mods that help with optimizations

So there you have it, replace the poor performance from the default minecraft engine and get up to 16x performance just by fixing its rendering pipeline.

Older post here which includes info on how to install Optifine: https://www.reddit.com/r/Amd/comments/l7ak6a/minecraft_players_make_sure_to_use_optifine_or/

Edit: Wow thanks for all the support guys, glad its helping people out! :)

Disable Auto Jump by Default on Java

Pretty simple, really. We use keyboards... with a space key... to jump... while playing on a computer set up... You know, the systems that run Java? I can promise you that anyone playing Java who needs auto jump is in the minority.

The entirety of the people I play with all get extremely frustrated when switching between 1.8 and the versions with auto jump (1.10+ I think) because every time they need to go in and disable the feature...

And although there are many ways to get around this with managing game instances and launcher profiles (I have a dozen different launcher profiles just so I can ensure that the settings I prefer are always set to the exact numbers I like them at), it's far easier to just have the feature disabled by default!

Also, if this is listed in the "frequently posted suggestions" list, why isn't it done yet? It's been 3 years! The only logical conclusion is that nobody has suggested this idea ever considering how easy it is to disable a feature like this.

It is literally as easy as having the default generated options.txt file have this:

autoJump:true

Changed to this:

autoJump:false

By the way, this setting doesn't require any digging at all. It is located on the second line in the options.txt file.

Finally made my first Java program!

In college, I was introduced to coding through MATLAB and fell in love. Telling a computer to do all the hard work for you? Yes! But once I graduated and started working, I didn't have the time to continue learning. Then, Covid happened and I found myself without a job and decided that I finally have the time to learn a skill I'm so fond of. I tried learning Java through Codecademy and just didn't feel like I learned anything, so I bought Head First to try to actually learn some theory. After chapter 6 I still felt like I wasn't learning HOW to code, so I went to kattis for some prompts to test out if I even knew anything. To my surprise I was able to write my first ever Java program!

Even though it's a 29 line code that calculates distance given speed and time, this is great motivation to keep doing what I'm doing!

Thank you to the community for motivating me whenever I'm sitting around browsing Reddit. Anytime I see a success story of someone earning a job from being self-taught, it motivates me to put in even an hour at a time to work towards my goal.

Minecraft Java Edition 1.16.5 has been released!

Happy Friday! We are now releasing 1.16.5, which fixes two critical stability issues that could cause servers to crash. We are not releasing more information about these issues at this time to protect servers that have not yet updated.

This release is network compatible with 1.16.4 - this means you do not need to upgrade your game right away to play on an upgraded server. However, we highly encourage all server owners to update as soon as possible to apply the stability fixes.

Next week, we aim to release the next snapshot of Caves & Cliffs. Stay tuned!

This update can also be found on minecraft.net.

Get the Release

To install the release, open up the Minecraft Launcher and click play! Make sure your Launcher is set to the "Latest Release" option.

Cross-platform server jar:

Java 4X game available as open-source

I don't talk about my open-source project on this subreddit very much, but the code has been open for almost a year now and the game has been so well-received that I figure maybe I should remind my fellow Java developers about it.

It's a "space 4X" strategy game called "Remnants of the Precursors" which is in turn a very faithful modernization of the 1993 classic "Master of Orion".

The source code is on github at https://github.com/rayfowler/rotp-public

The game is downloadable from itch.io: https://rayfowler.itch.io/remnants-of-the-precursors

When I originally started development of this game in 2015, like most developers I hilariously assumed that I would finish it in about a year and re-use artwork from the original game or get something on the cheap. But in the process of finding an artist online, I ran into this amazing artist named Petar Penev and decided to go "all in" on this project because he was just so talented.

Like so many of you, I've learned first-hand that you can make a really good salary as a Java dev, so I self-funded this project for about 3 years until I retired in 2018 (I'm old, sue me). I was extremely lucky that a friend at my job was super well-versed in sci-fi and was actually a talented writer having to pay his way through life as a technical writer. So he has done a tremendous job with the writing in the game.

Finally, my wife is an illustrator by trade and got sick of looking at my terrible "programmer UIs" and embarked on a several-year effort to remake all of the UIs in the game in her spare time. This of course required a tremendous amount of re-coding on my side because I instructed her to design her UIs completely in Paintshop and then let me figure out how to implement it in Java. Sometimes I have nightmares about gradients and wake up screaming.

She also made this trailer last year for the game: https://www.youtube.com/watch?v=VusDAxLpJ9I

Once I reached "feature complete" and started an open beta last Spring, I finally opened up the source code because I thought most of the churn was done. Since then, I've enjoyed the benefits of several Java developers contributing to the project and helping improve it.

I'm not asking anyone in here to contribute. The game is basically done! But if you are curious at how the "sausage is made" for a video game that has surprisingly turned out very well, feel free to clone the repo and take a look at the code. I've never made a video game before and the source code reflects th

Seasoned java developer that wants to get into C++ seeking advice

Hello, I'm a seasoned Java (and Clojure) developer and I want to make a shift in my career. I'm a bit sick of Java projects, and I want to get into C++ so I can work on more "industrial" projects.

I'm selling myself as a Java expert (so I already know about programming, algorithms, design patterns, reusable code, testing, ...). I've reasonable knowledge of computer architecture (CPU pipelines, cache lines, filesystems, ...) and system programming (can read some asm, syscalls, heap, stack, program sections, ...). What I'm looking for is the right gateway to learn quickly modern C++.

If your are same as me, I would really love to have some feedback from you.

Do you have a curated list of reading suggestions ? I can be a famous source code, a book, or a community to follow.

My IDE is Intellij on Linux, should I switch to CLion or something else ?

Many thanks for your help.

PS : obviously typing C++ in google gives a lot of (outdated) informations. I'm asking help from humans, not an algorithm ;)

Does age matters as a software dev to live and work to Japan? 31 - European, finishes degree at 35, 1.5years java software dev experience currently.

Hi!

I was trying to google it, but unfortunately i couldn't find any useful sources. Only a gentleman from the states who was asking if he is able to move to Japan at the age of 35 as a c# developer. So don't bite my head off, if my google search was lazy :D

I am 31 and starting my Bsc(3 year) in Computer Science. Altough I am working as a dev in Java for 1.5 years now(Bootcamp Graduate). I started to learn japanese a year ago, I think I am on an N3 level and will definitely go to N2 in the 3 years period. I am going to study CS while working. Also, I will have more years of experience under my belt along with the degree.

University always starts at 4pm and finishes at 10pm. I will be working from 7am to 3.30pm. Same school curriculum as morning classes.

Can anyone tell me please, how realistic is it to move to Japan at 35/36 with 5 years of experience with a fresh degree and get a job in CS?

Thank you for your answers in advance!
