# EntityLib EntityLib is a PacketEvents addon that provides an abstraction over raw entity data and packets to make it easier to work with entities as a whole. Currently, EntityLib is only stable for 1.18+, but it will support all versions that PacketEvents supports in the future.
For general support and reports of bugs, join the [Discord](https://discord.gg/jawR25hrSK) server. Gradle (Groovy DSL): ```groovy //https://jitpack.io/#Tofaa2/EntityLib/ repositories { maven { url 'https://jitpack.io' } } dependencies { implementation 'com.github.Tofaa2.EntityLib:::") } ``` Maven: ```xml com.github.Tofaa2.EntityLib (platform) (latest-release-version) ``` ## NOTE: EntityLib does not provide packet-events as a dependency, you must have it in your classpath already. EntityLib will also stay at the latest packet-events version at all times ## Features - Full EntityMeta support - Creation of WrapperEntities - Keeping track of entities. ## Usage For more realistic examples, please take a look at the `test-plugin` module. It has an example `Bukkit` plugin that uses EntityLib. Examples below show usage of the spigot module of entity lib, but the usage is the same for all platforms. ### Using the EntityMeta api ```java class Example { public static void main(String[] args) { PacketEventsAPI api = ;// create PacketEventsAPI instance SpigotEntityLibPlatform platform = new SpigotEntityLibPlatform(this); APIConfig settings = new APIConfig(PacketEvents.getAPI()) .debugMode() .tickTickables() .trackPlatformEntities() .usePlatformLogger(); EntityLib.init(platform, settings); // Making a random entity using packet events raw, i strongly recommend using the EntityLib#createEntity method instead int entityID = 1; WrapperPlayServerSpawnEntity packet = new WrapperPlayServerSpawnEntity(constructor args); EntityMeta meta = EntityMeta.createMeta(entityId, EntityType); // You can cast the meta to the correct type depending on the entity type PigMeta pigMeta = (PigMeta) meta; // Once you're done modifying the meta accordingly, you can convert it to a packet, and send it to whoever you want for them to see the changes. WrapperPlayServerEntityMetadata metaPacket = meta.createPacket(); User.sendPacket(metaPacket); } } ``` ### Creating a WrapperEntity ```java import com.github.retrooper.packetevents.protocol.world.Location; class Example { public static void main(String[] args) { PacketEventsAPI api = ;// create PacketEventsAPI instance SpigotEntityLibPlatform platform = new SpigotEntityLibPlatform(this); APIConfig settings = new APIConfig(PacketEvents.getAPI()) .debugMode() .tickTickables() .trackPlatformEntities() .usePlatformLogger(); EntityLib.init(platform, settings); WrapperEntity entity = EntityLib..getApi().createEntity(UUID, EntityType); // optional uuid and entity id // You can keep track of the entity yourself or store its entityId or uuid and fetch it using EntityLib.getApi().getEntity(UUID or entityId) // Entities also have access to the EntityMeta api, the EntityMeta api can be used seperately from wrapper entities but also can be used together EntityMeta meta = entity.getEntityMeta(); // Depending on the entity type, you can safely cast the meta to the correct type PigMeta meta1 = (PigMeta) meta; // If the entity type is EntityTypes.PIG // adding a viewer to the entity can be done before or after spawn, doesnt matter entity.addViewer(User); // UUID also applicable entity.removeViewer(User); // UUID also applicable entity.spawn(Location); // Spawns the entity at the given location entity.remove(); // Removes the entity from the world entity.rotateHead(float yaw, float pitch); // Rotates the head of the entity entity.teleport(Location); // Teleports the entity to the given location. // If the entityId provider for WrapperEntities is not working for you or needs changing, you can get it from EntityLib#getEntityIdProvider() // You can also set it to a custom provider if needed by calling EntityLib#setEntityIdProvider(EntityIdProvider) int randomEntityId = EntityLib.getPlatform().getEntityIdProvider().provide(); } } ``` ### TODO: Once this list is complete, i will release a stable version of the library. - [ ] Implement checks for each EntityMeta to make sure the version specific data is correct. - [ ] Verify all the EntityMeta packets are working correctly. - [ ] WrapperEntities must seamlessly send packet updates to viewers, currently they are not. - [ ] Add support for more actions using WrapperEntities. - [ ] More javadocs. - [x] Make ObjectData actually useful. - [ ] Multi-version support, currently only 1.18+ is stable. - [ ] Make class names match the protocol specified names. - [ ] Ideally, refactor the API to use a custom world that stores the entities, rather than one big map. This way we can access other data aswell from the world. This also requires me writing some other platform implementations by default. ### Credits - PacketEvents for providing the API and retrooper being a cool guy in general - Minestom certain mappings were taken from Minestom cause i have not slept in 4 days and it was faster
