# What is Distant Horizons?
Distant Horizons is a mod which implements a [Level of Detail](https://en.wikipedia.org/wiki/Level_of_detail_(computer_graphics)) system to Minecraft.\
This allows for far greater render distances without harming performance by gradually lowering the quality of distant terrain.
Below is a video demonstrating the system:

## Source Code Installation
### Prerequisites
* A Java Development Kit (JDK) for Java 17 (recommended) or newer.
Visit https://www.oracle.com/java/technologies/downloads/ for installers.
* Git or someway to clone git projects.
Visit https://git-scm.com/ for installers.
* (Not required) Any Java IDE with plugins that support Manifold, for example IntelliJ IDEA.
**If using IntelliJ:**
1. Install the Manifold plugin
2. Open IDEA and import the build.gradle
3. Refresh the Gradle project in IDEA if required
**If using Eclipse: (Note that Eclipse doesn't support Manifold's preprocessor!)**
1. Run the command: `./gradlew geneclipseruns`
2. Run the command: `./gradlew eclipse`
3. Make sure eclipse has the JDK 17 installed. (This is needed so that eclipse can run minecraft)
4. Import the project into eclipse
## Switching Versions
To switch between different Minecraft versions, change `mcVer=1.?` in the `gradle.properties` file.
If running in an IDE, to ensure the IDE noticed the version change, run any gradle command to refresh gradle.\
In IntelliJ, you will also need to do a gradle sync if it didn't happen automatically.
## Compiling
Prerequisites:
- JDK 17 or newer
From the File Explorer:
1. Download and extract the project zip
2. Download the core from https://gitlab.com/jeseibel/distant-horizons-core and extract into a folder called `coreSubProjects`
3. Open a terminal emulator in the project folder (On Windows you can type `cmd` in the title bar)
4. Run the commands: `./gradlew assemble` (You may need to use a `.\` on Windows)
5. Merge the jars with `./gradlew mergeJars`
6. The compiled jar file will be in the folder `Merged`
From the command line:
1. `git clone --recurse-submodules https://gitlab.com/jeseibel/distant-horizons.git`
2. `cd minecraft-lod-mod`
3. `./gradlew assemble`
4. `./gradlew mergeJars`
5. The compiled jar file will be in the folder `Merged`
Run tests with: `./gradlew test`
>Note: You can add the argument `-PmcVer=?` to tell gradle to build a selected MC version instead of having to modify the `gradle.properties` file.\
> For example: `./gradlew assemble -PmcVer=1.18.2`
## Compiling with Docker
`./compile `
You can also locally compile the DH jars without a Java environment by using Docker. Where `` is the version of Minecraft to compile for (ie `1.20.1`), or the keyword `all`. See [Versions](#minecraft-and-library-versions) for a list of all supported values.
## Other commands
`./gradlew --refresh-dependencies` to refresh local dependencies.
`./gradlew clean` to delete any compiled code.
## Note to self
The Minecraft source code is NOT added to your workspace in an editable way. Minecraft is treated like a normal Library. Sources are there for documentation and research purposes only.
Source code uses Mojang mappings & [Parchment](https://parchmentmc.org/) mappings.
To generate the source code run `./gradlew genSources`
If your IDE fails to auto-detect the source jars when browsing Minecraft classes; manually select the JAR file ending with -sources.jar when prompted by your IDE.
(In IntelliJ it's at the top where it says "choose sources" when browsing a Minecraft class)
## Other Useful commands
Run the standalone jar: `./gradlew run`
Build the standalone jar: `./gradlew core:build`
Only build Fabric: `./gradlew fabric:assemble` or `./gradlew fabric:build`
Only build Forge: `./gradlew forge:assemble` or `./gradlew forge:build`
Run the Fabric client (for debugging): `./gradlew fabric:runClient`
Run the Forge client (for debugging): `./gradlew forge:runClient`
To build all versions: `./buildAll` (all builds will end up in the `Merged` folder)
