Take the main Blockland shortcut that you want to use, then click "properties".
Take note of "target", it should look something like this:
C:\Blockland\BlocklandLauncher.exe
This will be where the launcher is located. Since you said in another post that you run BL from a flash drive, move the launcher onto the flash drive. Then, change the target as such, assuming the target is F:
F:\path\of\launcher\on\drive -profilePath "F:\path\of\launcher\on\drive"
Next, run the shortcut that was just changed. This will redownload all the default files to the flash drive. Once this is complete, copy all the files from the Blockland folder in Document into the installation location of the Blockland copy on F: . This will restore all your custom settings and add-ons to this new copy.
Now, you've got a copy running from a flash drive.
You have to do the same for every shortcut for the game and leave any "-dedicated" or "-dedicatedLAN" switches there.
Once you've completed this for every shortcut that you want to, just copy the shortcuts onto the flash drive.
