This release fixes some bugs.
Update 1.11 added new features that can be useful when migrating a world to Minecraft 1.16. Here is a document with some tips and tricks regarding 1.16.
Details:
- Fixed a bug where filtering for chunks containing air wouldn't work correctly
- Fixed a bug where
LOCALAPPDATA
on Windows was divided into two paths because it was using the same code used for Linux that divided environment variables containing multiple paths into their individual pieces. - Updated entity mappings to include new entities added in recent snapshots
- Updated installation instructions to include a Java version check in the console.
"Requirements":
- Either:
- 64bit JRE 8+, you can get it from HERE
- A Minecraft Java Edition installation
- A computer
- At least 6 GB of RAM. If lower, more RAM has to manually be assigned to the JVM using the
-Xmx
argument. Assigning 4 GB is recommended.
- At least 6 GB of RAM. If lower, more RAM has to manually be assigned to the JVM using the
- A brain
What works on most systems
Most likely, .jar
files are associated with java on your computer, it should therefore launch by simply double clicking the file (or however your OS is configured to open files using your mouse or keyboard). If not, you can try java -jar mcaselector-1.12.3.jar
from your console. If this doesn't work, you might want to look into how to modify the PATH
variable on your system to tell your system that java is an executable program.
If you have Minecraft Java Edition installed
Minecraft Java Edition comes with a JRE that you can use to start the MCA Selector, so there is no need to install another version of Java on your system.
For Windows:
- Hold
Shift
and Right-click on an empty space and selectOpen PowerShell window here
(Open Command window here
on Windows 8 and earlier). - Type
C:\Program Files (x86)\Minecraft\runtime\jre-x64\bin\java -jar
, then drag and drop themcaselector-1.12.3.jar into the console
and pressEnter
.
For MacOS:
- Press
Cmd+Space
, typeTerminal
and pressEnter
. - Type
~/Library/Application\ Support/minecraft/runtime/jre-x64/jre.bundle/Contents/Home/bin/java -jar
(with a space at the end), then drag and drop themcaselector-1.12.3.jar
into the console and pressEnter
.
WARNING: For MacOS 10.14+ (Mojave) It is NOT recommended to use the JRE provided by Minecraft (1.8.0_74), because it contains a severe bug that causes JavaFX applications to crash when they lose focus while a dialog window (such as the save-file-dialog) is open (see the bug report here). This bug has been fixed in Java 1.8.0_201 and above.
If you receive a JavaFX error
"When I run mcaselector-1.12.3.jar
, an error dialog appears that looks like this:"
Open the console or terminal on your OS.
For Windows:
- Hold
Shift
and Right-click on an empty space on your desktop and selectOpen PowerShell here
(Open Command window here
on Windows 8 and earlier).
For MacOS:
- Press
Cmd+Space
, typeTerminal
and pressEnter
.
Type the command java -version
and press Enter
. If the output shows that your java command is linked to java version "1.8.0"
, you can simply run MCA Selector through the console.
For Windows and MacOS:
- Type
java -jar
(with a space at the end) and drag and drop themcaselector-1.12.3.jar
into the console and hitEnter
.
For Linux:
- Run
java -jar <path to mcaselector-1.12.3.jar
where you replace everything in<>
.
If the output shows a Java version higher than Java 8, please find and download the appropriate JavaFX version from Here. If you know what to do, do it. If you don't, follow these steps:
For Windows:
- Download "JavaFX Windows SDK" for your Java version from here.
- Unzip the
.zip
-file with your program of choice, then navigate into the unzipped folder. - Hold
Shift
and Right-click on an empty space in that folder and selectOpen PowerShell window here
(Open Command window here
on Windows 8 and earlier). Typejava --module-path
(with a space at the end), then drag and drop thelib
-folder into the console. Continue to type--add-modules ALL-MODULE-PATH -jar
(with a space at the beginning and the end), then drag and drop themcaselector-1.12.3.jar
into the console and hitEnter
.
For MacOS:
- Download "JavaFX Mac OS X SDK" for your Java version from here.
- Double-click the
.zip
-file to unpack, then navigate into the unzipped folder. - Press
Cmd+Space
, typeTerminal
and pressEnter
. Typejava --module-path
(with a space at the end), then drag and drop thelib
-folder into the console. Continue to type--add-modules ALL-MODULE-PATH -jar
(with a space at the end), then drag and drop themcaselector-1.12.3.jar
into the console and hitEnter
.
For Linux:
- Download "JavaFX Linux SDK" for your Java version from here.
- Unzip the
.zip
-file with your program of choice. - Open the command prompt and run
java --module-path <path to unzipped folder>/lib --add-modules ALL-MODULE-PATH -jar <path to mcaselector-1.12.3.jar>
where you replace everything in<>
with the appropriate paths. - Some distributions like AdoptOpenJDK (shipped with most Linux distributions) do not ship with JavaFX by default. On Debian, an open version of JavaFX is contained in the
openjfx
package. This or some other installation of JavaFX is required to run themcaselector-1.12.3.jar
.
