We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: TBD -- Update: Fri 10/20 11pm UTC - We have encountered some unexpected issues. Our staff is working around the clock to complete this process as quickly as possible. Thank you for your patience.
Tutorials/Update LWJGL (Legacy)
|This tutorial contains content that is no longer applicable to current versions of the game.
The launcher is capable of automatically updating LWJGL, and the most recent version is currently used.
What is LWJGL?[edit | edit source]
LWJGL is the LightWeight Java Game Library. Essentially, it is what Minecraft uses for graphics, sound, and input. The latest version of LWJGL is 3.0.
Prior to release 1.6, Minecraft used LWJGL 2.4.2. Minecraft 1.8.1 currently uses LWJGL 2.9.2, and the launcher is able to automatically update it to newer versions, making the steps in this guide unnecessary. Updating to LWJGL 3.0 requires non-negligible code changes and is outside of the scope of this tutorial.
Why update?[edit | edit source]
- Updating will fix some input bugs where keys seem to get stuck if you click at the same time. It also removes the "ghost" mouse pointer clicking.
- Some users report a performance increase upon updating.
- This can also potentially fix some issues regarding sound not working/cutting out.
- It has been reported to fix intermittent crashes on Windows.
- It has also been known to resolve the "cannot get JAWT interface" error for Mac users using Java 7.
- Some Linux distributions, such as openSUSE, require LWJGL to be updated before Minecraft can even run. Trying to run Minecraft without updating LWJGL may create a black screen upon loading. If you cannot play Minecraft on your Linux distribution, chances are that this is the problem.
Where to download[edit | edit source]
Select the latest stable release and download the lwjgl-X.X.X.zip. You should also backup your .minecraft folder before following the steps below. As a last resort, you can use the Minecraft Launcher's Force Update option to reset the files.
Notes[edit | edit source]
- With 2.8.1, on most 64 bit computers, the lwjgl64.dll update will cause a black screen crash. You can revert to the backup version you have saved if needed.
- Again on several 64 bit computers, the OpenAL64.dll update can cause a sound glitch that makes bursting sounds. Keep a backup in case you need to rollback.
- Version 2.8.5 generally breaks shift-clicking; 2.8.4 and 2.9.0 do not. You can change the url in your browser to access 2.8.4 or 2.9.0 rather than 2.8.5.
- LWJGL 2.8.5 has a bug which sends a false signal that the user released all currently pressed keyboard keys when a mouse button is pressed. That means that your building will be significantly slower. Do not update to this version if this bothers you.
- This bug seems to be fixed when playing in fullscreen mode (Default F11), or updating to LWJGL 2.9.0.
What to replace[edit | edit source]
In the lwjgl-X.X.X.zip, there should be two folders, named jar and natives. You should replace the files in .minecraft/bin and .minecraft/bin/natives with the versions from the .zip.
The .minecraft folder's location varies by operating system.
All operating systems[edit | edit source]
You should replace these files in .minecraft/bin/
Windows[edit | edit source]
You should replace these files in .minecraft\bin\natives\
*This needs updating. The current version of LWJGL (3.0 and higher) doesnt use the same natives set.
Mac[edit | edit source]
You should replace these files in minecraft/bin/natives/
- For this one, create a copy of openal.dylib, then rename it to libopenal.dylib
GNU/Linux[edit | edit source]
You should replace these files in .minecraft/bin/natives/
Alternatively, a user may install the "liblwjgl-java" package and its dependencies via a package manager. On Debian-like systems (Ubuntu, Mint, etc.) a potential root-user command line would be:
apt-get install liblwjgl-java
