[Guide] Portable Minecraft

Redisle

Im not an active member on this forum but I do play Minecraft on a server with some friends and I just cooked this up and thought it may be useful to someone here.

Basically the computers in college don't have java installed and are completely locked down and I wanted to be able to play Minecraft in college. Probably a terrible idea but anyway.

If your computer has java installed you can probably just run the normal exe regardless (or use the website) but this is useful for those without java, usually in colleges/workplaces/libraries etc. Obviously it won’t run on everything, you do need a certain minimum spec.



Firstly you are going to need a flash drive. Faster the better as minecraft makes a lot of use of the disk. The other option is to setup as below then package to an rar file or similar and extract to local hard disk to run. Should work either way.

Firstly open up your flash drive and create the following folders:

X:\Minecraft
X:\Minecraft\Data
X:\Minecraft\jar

X:\ = Whatever drive letter windows assigns to your flash drive.

Next you need to download Portable Java.
Run the installer and follow the prompts. Set the install path to X:\Minecraft\Java.

When that’s done download the Minecraft.jar file under Linux/Other
and place it in X:\Minecraft\jar.

Now you need to create a batch file to launch minecraft. Create a new text document and enter the following:

set APPDATA=\Minecraft\Data
 
Minecraft\Java\bin\Java.exe -jar Minecraft\jar\Minecraft.jar

This sets the working folder to the Data folder on your flashdrive instead of the local AppData folder and then launches the Minecraft.jar file using java.exe.

Save your text file as minecraft.bat and place it in the root of your flash drive. You may need to turn off the “Hide extensions of known file types” option in folder view options to do this properly.

Now launch minecraft using your batch file and you should be good to go. At this point if you login it should download the game files to the Data folder on the flash drive and if you attempt to play at a computer where you can’t access the server you can play offline just fine.

Hope it’s of use to someone.

That dosent include Java. I specifically said this is for situations where Java is not installed to the local machine and you don't have install rights....

Just so you know, the link to Portable Java has a fullstop at the end.

Great guide though!

Not sure how to edit posts but my previous post means that the link is invalid.

If your using Linux, it's already portable.
