# 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. <br>
|
|
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:<platform>:<latest-release-version'
|
|
}
|
|
```
|
|
|
|
Gradle (Kotlin DSL):
|
|
```kotlin
|
|
repositories {
|
|
maven(url = "https://jitpack.io")
|
|
}
|
|
|
|
dependencies {
|
|
implementation("com.github.Tofaa2.EntityLib:<platform>:<latest-release-version>")
|
|
}
|
|
```
|
|
|
|
Maven:
|
|
```xml
|
|
<dependency>
|
|
<groupId>com.github.Tofaa2.EntityLib</groupId>
|
|
<artifactId>(platform)</artifactId>
|
|
<version>(latest-release-version)</version>
|
|
</dependency>
|
|
```
|
|
|
|
## 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.
|
|
- [x] WrapperEntities must seamlessly send packet updates to viewers, currently they are not.
|
|
- [x] Add support for more actions using WrapperEntities.
|
|
- [x] More javadocs.
|
|
- [x] Make ObjectData actually useful.
|
|
- [ ] Multi-version support, currently only 1.18+ is stable.
|
|
- [ ] Make class names match the protocol specified names.
|
|
|

### 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
