It extends the normal view distance without sacrificing server performance using asynchronous player processing, direct chunk reading from disk, and caching of chunk data. ## Features - Asynchronous fast player ticking on networking threads - Reads chunks directly from disk without loading them - Optimized chunk state tracking and chunk iteration - Configurable chunk data caching for fast access - Configurable limitations for chunk sending and chunk generation - Per-dimension configuration options - Lightweight anti-xray support for extended chunks

Example: Loading speed for a view distance of 127 chunks

The screenshot below was taken at `0 2250 0` in the end dimension with a view distance of 127 chunks (with fog disabled). On an AMD Ryzen 7 5800X, all visible chunks were transmitted to the client in about 12 seconds after having joined the server with a cold cache and in about 9 seconds with a warm cache.

### Supported Software | Minecraft Version | Paper | |-------------------|-------| | 26.3.x | ✅ | | 26.2.x | ✅ | | 26.1.x | ✅ | | 1.21.11 | ✅ | | 1.21.10 | ✅ | | 1.21.9 | ✅ | | 1.21.8 | ✅ | | 1.21.7 | ✅ | | 1.21.6 | ✅ | | 1.21.5 | ✅ | | 1.21.4 | ✅ | | 1.21.3 | ✅ | | 1.21.1 | ✅ | ## Usage On Paper servers, place the jar file in your `plugins` directory and restart your server. By default, BetterView will configure a view distance of 32 chunks for each dimension. ### Configuration On the first start, this plugin will automatically create a configuration file. If using Paper it will be created at `plugins/BetterView/config.yml`. In there, you are able to configure the following options: - `config-version`: Don't touch this - `integrated-server-render-distance`: Only relevant for singleplayer worlds, this allows replacing the render distance of the integrated server as BetterView would otherwise have no effect (default: `-1`, disabled) - `global`: - `enabled`: Whether to enable or disable the entire plugin/mod (default: `true`) - `chunk-generation-limit`: How many new chunks can be generated globally in one tick (default: `3`) - `chunk-send-limit`: The maximum amount of chunks sent to a player in a tick (default: `3`) - `dimensions`: - `` (e.g. `minecraft:overworld`): - `enabled`: Whether to enable or disable the plugin/mod for this dimension (default: `true`) - `chunk-generation-limit`: How many new chunks can be generated for this level in one tick (default: `2`) - `chunk-queue-size`: How many chunks can be queued per player at once (default: `16`) - `view-distance`: The maximum extended view distance for this dimension (default: `32`) - `cache-duration`: The cache duration for how long extended chunks should be kept in memory (default: `PT5M`, 5 minutes) - Make sure to adjust the cache duration based on what you use your server for; for e.g. static lobby servers, you can use a longer cache duration than for dynamic SMP servers. If the cache duration is too high, chunks will display outdated content after e.g. a rejoin. - `anti-xray`: - Be aware that this plugin implements a lightweight version of anti-xray, which doesn't check if a block is exposed to air or not. This means that every engine-mode other than `HIDE` will probably not look very good. - `enabled`: Whether anti-xray will be enabled or disabled in this world (default: `false`) - `engine-mode`: Engine modes of anti-xray, either `HIDE`, `OBFUSCATE`, or `OBFUSCATE_LAYER` (default: `HIDE`) - `hidden-blocks`: The list of blocks to hide/obfuscate (default: all ores and all base blocks of dimensions) - `chunk-batches`: - Chunk batches are used to ensure the client/internet of players doesn't get overwhelmed by too many chunks being sent at once. If enabled, BetterView sends a chunk batch and waits for the player to acknowledge they received the full chunk batch. Only then the next batch of chunks will be sent. \ A side effect of this will be that players with good connectivity but high latency will receive chunks at a much slower rate than possible. \ *Note: chunk batches may be sent across multiple ticks.* - `enabled`: Whether chunk batches are enabled or disabled in this dimension (default: `true`) - `chunks-per-batch`: The amount of chunks in a single batch (default: `12`) - `prepare-chunks-while-waiting`: Whether BetterView should continue preparing chunks while waiting for acknowledgement of previous batch (default: `true`) - `batch-timeout`: The amount of time without a chunk being sent after which a batch expires (default: `PT5S`) - `batch-wait-timeout`: The timeout after which BetterView automatically marks the batch as done, even without a player response (default: `PT30S`) Feel free to play around with the chunk generations and chunk sending limits for an optimal experience on your server setup. ## API Usage Maven Repository: `https://repo.minceraft.dev/releases/` \ Maven Artifact: `dev.booky.betterview:betterview-api:2.2.1` \ Javadoc: https://repo.minceraft.dev/javadoc/releases/dev/booky/betterview/betterview-api/2.2.1

Example for Paper

```java // get the BetterView API instance using Bukkit's ServicesManager // this is the only difference between using the API on paper and fabric BvManager bvManager = Bukkit.getServicesManager().load(BvManager.class); if (bvManager == null) { throw new IllegalStateException("Failed to load BetterView API"); } // invalidate chunk cache at 0 0 in the overworld BvLevel overworld = bvManager.getLevel(Key.key(Key.MINECRAFT_NAMESPACE, "overworld")); overworld.invalidateChunkCache(0, 0); // refresh the chunk for all players in the overworld for (BvPlayer player : overworld.getPlayers()) { // (switch to proper thread for thread-safety) player.getExecutor().execute(() -> { if (!player.isActive() || player.getLevel() != overworld) { // player isn't active or isn't in overworld - maybe they have switched // dimensions in the short time it took for this code to run? return; } // ensure BetterView actually "owns" the chunk at 0 0 if (player.getChunkLifecycle(0, 0).isOwned()) { // finally, queue the chunk to be refreshed! player.refreshChunk(0, 0); } }); } ```

Please note that the API is still work in progress. Please be sure to post suggestions, enhancements or any other ideas on our [Discord](https://discord.gg/zC8xjtSPKC) or in the issue tracker. ## Building 1. Clone the project (`git clone https://github.com/MinceraftMC/BetterView.git`) 2. Go to the cloned directory (`cd BetterView`) 3. Build the jar files (`./gradlew build` on Linux/MacOS, just `gradlew build` on Windows) The jar files can be found in the `build` → `libs` directory. ### Contributing If you want to contribute to BetterView, feel free to fork the repository and create a pull request. Please make sure to follow the code style and conventions used in the project. If you have any questions or need help, feel free to ask in our [Discord](https://discord.gg/zC8xjtSPKC). You can test your changes by running `./gradlew :paper:runServer`. This will start a local server with the compiled plugin automatically installed, ready for debugging in your IDE.
