== What is LWJGL? ==
|
|
[[wikipedia:LWJGL|LWJGL]] is the '''L'''ight'''W'''eight '''J'''ava '''G'''ame '''L'''ibrary. LWJGL provides Minecraft with access to [[w:OpenGL|OpenGL]] for graphics, [[w:OpenAL|OpenAL]] for sound and [[w:GLFW|GLFW]] for window and input management. The Minecraft launcher automatically updates to the latest version of '''LWJGL'''.
|
|
|
|
== Why update? ==
|
|
* 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 ==
|
|
|
|

|
|
|
|
Select the latest stable release and download the lwjgl-X.Y.Z.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 ===
|
|
* 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 {{key|F11}}), or updating to LWJGL 2.9.0.
|
|
|
|
== What to replace ==
|
|
|
|
In the lwjgl-X.Y.Z.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 ===
|
|
You should replace these files '''in .minecraft/bin/'''
|
|
* Jinput.jar
|
|
* Lwjgl.jar
|
|
* Lwjgl_util.jar
|
|
|
|
=== Windows ===
|
|
You should replace these files '''in .minecraft\bin\natives\'''
|
|
* jinput-dx8.dll
|
|
* jinput-dx8_64.dll
|
|
* jinput-raw.dll
|
|
* jinput-raw_64.dll
|
|
* lwjgl.dll
|
|
* lwjgl64.dll
|
|
* OpenAL32.dll
|
|
* OpenAL64.dll
|
|
<nowiki>*</nowiki>This needs updating. The current version of LWJGL (3.2 and higher) doesn't use the same natives set.
|
|
|
|
=== Mac ===
|
|
You should replace these files '''in minecraft/bin/natives/'''
|
|
* libjinput-osx.jnilib
|
|
* liblwjgl.jnilib
|
|
* openal.dylib
|
|
* libopenal.dylib
|
|
** For this one, create a copy of openal.dylib, then rename it to libopenal.dylib
|
|
|
|
=== GNU/Linux ===
|
|
You should replace these files '''in .minecraft/bin/natives/'''
|
|
* libjinput-linux.so
|
|
* libjinput-linux64.so
|
|
* liblwjgl.so
|
|
* liblwjgl64.so
|
|
* libopenal.so
|
|
* libopenal64.so
|
|
|
|
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
