ReplayMod

A Minecraft mod to record game sessions and replay them afterwards from any perspective.

Building

Make sure your sub-projects are up-to-date: git submodule update --init --recursive

For compiling 1.7.10, you must run ./gradlew :jGui:1.7.10:setupDecompWorkspace :1.7.10:setupDecompWorkspace once after the initial clone. This may take quite some time.

No IDE

You can build the mod by running ./gradlew build (or just ./gradlew shadowJar). You can then find the final jar files in versions/$MCVERSION/build/libs/. You can also build single versions by running ./gradlew :1.8:build (or just ./gradlew :1.8:shadowJar) (builds the MC 1.8 version).

IntelliJ

Ensure you have at least IDEA 2020.1. Build the mod via Gradle as explained above at least once (./gradlew compileJava should be sufficient). This will ensure that the sources for all MC versions are generated. Then import the Gradle project from within IDEA: File -> Open -> build.gradle -> Open as Project Finally configure IDEA to build everything by itself instead of delegating it to Gradle (cause that is slow): File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle -> Build and run using: IntelliJ IDEA

Development

Branches

Loosely based on this branching model with stable instead of master.

TL;DR: Main development happens on the develop branch, snapshots are built from this branch. The stable branch contains the most recent release.

The master branch is solely to be used for the version.json file that contains a list of all versions used by the clients to check for updates of this mod.

The Preprocessor

To support multiple Minecraft versions with the ReplayMod, a JCP-inspired preprocessor is used. It has by now acquired a lot more sophisticated features to make it as noninvasive as possible. Please read the preprocessor's README to understand how it works.

Versioning

The ReplayMod uses the versioning scheme outlined here with three changes:

  • No MAJORAPI, the ReplayMod does not provide any external API
  • "Updating to a new Minecraft version" should not increment MAJORMOD, we maintain one version of the ReplayMod for each version of Minecraft and all these versions share the same feature set (and most bugs). We therefore try to keep the version name the same for all of them (with the exception of MCVERSION of course). This also means that the "Multiple Minecraft Version" section does not apply.
  • For pre-releases the shorter -bX is used instead of -betaX

When a new version is (pre-)release, a new commit modifying the version.txt file should be added and the versions.json file in the master branch should be updated. To simplify this process the gradle task doRelease can be used: ./gradlew -PreleaseVersion=2.0.0-rc1 doRelease. It will create the commit and update the version.json accordingly.

Care should be taken that the updated version.json is not pushed before a jar file is available on the download page (or Jenkins) as it will inform the users of the update.

Bugs

GitHub should generally be used to report bugs.

In the past, bugs were tracked via Bugzilla, so bug numbers in commits prior to 2020 such as (fixes #42) generally referred to Bugzilla unless noted otherwise.
