bspkrs' WorldStateCheckpoints mod for Minecraft (my fork/rework of MightyPork's discontinued Checkpoints Backup Mod). Allows you to save/load SSP world backups in-game. This repo contains source files for Forge (dependant on bspkrsCore).

The Java JDK is used to compile WorldStateCheckpoints.

1. Download and install the Java JDK.
   • Windows/Mac download link. Scroll down, accept the Oracle Binary Code License Agreement for Java SE, and download it (if you have a 64-bit OS, please download the 64-bit version).
   • Linux: Installation methods for certain popular flavors of Linux are listed below. If your distribution is not listed, follow the instructions specific to your package manager or install it manually here.
     • Gentoo: emerge dev-java/oracle-jdk-bin
     • Archlinux: pacman -S jdk7-openjdk
     • Ubuntu/Debian: apt-get install openjdk-7-jdk
     • Fedora: yum install java-1.7.0-openjdk
2. Set up the environment.
   • Windows: Set environment variables for the JDK.
     1. Go to Control Panel\System and Security\System, and click on Advanced System Settings on the left-hand side.
     2. Click on Environment Variables.
     3. Under System Variables, click New.
     4. For Variable Name, input JAVA_HOME.
     5. For Variable Value, input something similar to C:\Program Files\Java\jdk1.7.0_45 exactly as shown (or wherever your Java JDK installation is), and click Ok.
     6. Scroll down to a variable named Path, and double-click on it.
     7. Append ;%JAVA_HOME%\bin EXACTLY AS SHOWN and click Ok. Make sure the location is correct; double-check just to make sure.
3. Open up your command line and run javac. If it spews out a bunch of possible options and the usage, then you're good to go. If not try the steps again.

Gradle is used to execute the various build tasks when compiling WorldStateCheckpoints.

1. Download and install Gradle.
   • Windows/Mac download link. You only need the binaries, but choose whatever flavor you want.
     • Unzip the package and put it wherever you want, eg C:\Gradle.
   • Linux: Installation methods for certain popular flavors of Linux are listed below. If your distribution is not listed, follow the instructions specific to your package manager or install it manually here.
     • Gentoo: emerge dev-java/gradle-bin
     • Archlinux: You'll have to install it from the AUR.
     • Ubuntu/Debian: apt-get install gradle
     • Fedora: Install Gradle manually from its website (see above), as Fedora ships a "broken" version of Gradle. Use yum install gradle only if you know what you're doing.
2. Set up the environment.
   • Windows: Set environment variables for Gradle.
     1. Go back to Environment Variables and then create a new system variable.
     2. For Variable Name, input GRADLE_HOME.
     3. For Variable Value, input something similar to C:\Gradle-1.10 exactly as shown (or wherever your Gradle installation is), and click Ok.
     4. Scroll down to Path again, and append ;%GRADLE_HOME%\bin EXACTLY AS SHOWN and click Ok. Once again, double-check the location.
3. Open up your command line and run gradle. If it says "Welcome to Gradle [version].", then you're good to go. If not try the steps again.

Git is used to clone WorldStateCheckpoints and update your local copy.

1. Download and install Git here.
2. Optional Download and install a Git GUI client, such as Github for Windows/Mac, SmartGitHg, TortoiseGit, etc. A nice list is available here.

This section assumes that you're using the command-line version of Git.

1. Open up your command line.
2. Navigate to a place where you want to download WorldStateCheckpoints's source (eg C:\Development\Github\Minecraft\) by executing cd [folder location]. This location is known as mcdev from now on.
3. Execute git clone [email protected]:bspkrs/WorldStateCheckpoints.git. This will download WorldStateCheckpoints's source into mcdev.
4. Right now, you should have a directory that looks something like:

mcdev
\-WorldStateCheckpoints
    \-WorldStateCheckpoints's files (should have build.gradle)

1. Execute gradle setupDecompWorkspace. This sets up Forge and downloads the necessary libraries to build WorldStateCheckpoints. This might take some time, be patient.
   • You will generally only have to do this once until the Forge version in build.properties changes.
2. Execute gradle build. If you did everything right, BUILD SUCCESSFUL will be displayed after it finishes. This should be relatively quick.
   • If you see BUILD FAILED, check the error output (it should be right around BUILD FAILED), fix everything (if possible), and try again.
3. Go to mcdev\WorldStateCheckpoints\build\libs.
   • You should see a .jar file named [#.#.#]WorldStateCheckpoints-<version>.jar.
4. Copy the jar into your Minecraft mods folder, and you are done!

In order to get the most up-to-date builds, you'll have to periodically update your local repository.

1. Open up your command line.
2. Navigate to mcdev in the console.
3. Make sure you have not made any changes to the local repository, or else there might be issues with Git.
   • If you have, try reverting them to the status that they were when you last updated your repository.
4. Execute git pull master. This pulls all commits from the official repository that do not yet exist on your local repository and updates it.

So you found a bug in the code? Think you can make it more efficient? Want to help in general? Great!

1. If you haven't already, create a GitHub account.
2. Click the Fork icon located at the top-right of this page (below your username).
3. Make the changes that you want to and commit them.
   • If you're making changes locally, you'll have to do git add -A, git commit and git push in your command line.
4. Click Pull Request at the right-hand side of the gray bar directly below your fork's name.
5. Click Click to create a pull request for this comparison, enter your pull request title, and create a detailed description explaining what you changed.
6. Click Send pull request, and wait for feedback!

Crashing? Have a suggestion? Found a bug? Create an issue now!

1. Make sure your issue hasn't already been answered or fixed. Also think about whether your issue is a valid one before submitting it.
