Portable FTB

[T3amTact1cal]

So I'm trying to put FTB on my flashdrive so I could play it in programming class because I have so much spare time in it. So I know how to set up normal MC to play off your flashdrive. The reason I need to run it off my flashdrive is that my school monitors pretty much everything we download and If I do download FTB I can get suspended for couple days. I'v been playing Normal MC off my flashdrive and gave it to plenty other classmates and none of us got caught yet, so I think we are good to go. I tried to set up the main file from the launcher to make it in my flashdrive but it keeps messing up, so could someone give me a tip of setting it up for my flashdrive. Thanks in advance

Copy your entire FTB file to your flash drive. So, you have your launcher and your instance file. It should work if you do that. My flashdrive has an FTB folder with my FTB_Launcher.exe and my FTBBETA folder. It works from all computers just fine.

I'm not sure how it keeps messing up, but if the above doesn't work try a .bat file.

"C:\Program Files\Java\jre6\bin\java.exe" -Xms512m -Xmx1024m -jar FTB_Launcher.jar
pause

Make sure the path to the java is correct for your school computer (they may have java 7). Also change the Xms to whatever you desire (it's your min/max memory/ram usage)

Alternatively, download MultiMC and copy your FTBBETA or Magic Pack folder (with the instimod folder & minecraft folder) to the instances folder where your MultiMC is. Then copy your MultiMC folder to your flashdrive. You should run MultiMC from your flash drive with no problems.

To further complete this, you could download Java portable (MultiMC works with it very nicely)

Java Portable Site. Looks pretty cool. I could use this to run Java 7 on my school computers instead of Java 6 then, couldn't I? Do we need the PortablApps platform for it, or can it be run by itself? It says it works best on the platform, so I'm assuming we can run it by itself.

I managed to get some form of standalone Java, it was pretty much a copy of the Java folder usually placed in progran files

Thanks for the tip. but I'v already tried using MultiMC on my flashdrive and it does work well, but I don't know If I will be able to update the MC without loosing all my stuff, and also don't know how to install oftifine for MultiMC launcher thingy.

PS: The portal java thingy, will it fully download everything needed onto the flashdrive and just run the program off it, or will it download parts of files needed when hooked up and connected to the internet.

PPS: The issue I'm getting is when I set the launcher to use the FTB files off of my flashdrive, it makes a crazy directory to somewhere else or to my flashdrive. Then it thinks downloads all the FTB files, and when I try to launch it, it just stays at the launcher screen.

MultiMC has pretty much the exact same folder setup as FTB. So the optifine would go in the instimod folder just as it would for FTB. And I'm not sure what you mean by update MC and losing your stuff.

The FTB Launcher stores login info and launcher options in "AppData\Roaming\ftblauncher" so that might be causing your issue.

Using MultiMC is a good idea. Don't update Minecraft with it though. And when the modpack you're using is updated, move the minecraft and instmods folders back where they came from, update the pack with the FTB Launcher, then move it back into the MultiMC directory. That should work fine without erasing your data.

mine stores that info in the launcher folder

edit:
