Thread: Auto Updater Best Yet v1.1

basically instead of zipping your cache you can use this to generate a xml whitch you upload to your webserver aswell as your open cache and it will check the crc32 to the client cache files and if there outdated it will update them aswell as sprites ect and once the cache files are downloaded the client starts first time without a restart

in action:


Updates:
11/03/2011 - Added download speed updated Updater.java
13/03/2011 - The gui now does not show unless there are updates
14/03/2011 - Fixed up updater not downloading stuff in subfolders
14/03/2011 - Fixed download speed
14/03/2011 - Fixed crc genertator should fix all path errors
28/01/2014 - Removed uid.dat from getting added to patch.xml and also any files containing .java, .class or .jar
Patch Generator (this is not for the client):
dont put this in the cache directory just set the path to it and run it then go there to get patch.xml
or it will just add the classes and the batch to the update
