Hello, i am having problems with updating old plugin from 1.7.10 to 1.11. The problem is about the Custom Entities that are correctly registered and they even spawn, but the problem starts when i implements custom interface for much more control above entity bahaviour. This is class of an Custom Skeleton. Code (Text): public class CustomSkeleton extends EntitySkeleton implements ICustomEntity { private GBrain brain; private GEntityDefinition definition; private boolean sunBurn = true; public CustomSkeleton(World world) { super(world); } /** * * ** * CUSTOMIZED * * this part is totally new * ** * * **/ @Override public CraftEntity getBukkitEntity() { /*if (this.bukkitEntity == null) { this.bukkitEntity = new CraftCustomSkeleton(this.world.getServer(), this); } TODO May add With class */ return this.bukkitEntity; } @Override public GBrain getBrain() { return this.brain; } @Override public void setBrain(GBrain brain) { if (brain == null) return; clearPathfinders(); this.brain = brain.clone(); this.brain.connectToBody(this, this.goalSelector, this.targetSelector); this.brain.uploadConsciousness(); } @Override public void clearPathfinders() { PathFinder.clearPathFinders(this); } @Override public GEntityDefinition getDefinition() { return definition; } @Override public void setDefinition(GEntityDefinition definition) { this.definition = definition; } @Override public boolean getSunBurn() { return sunBurn; } @Override public void setSunBurn(boolean flag) { sunBurn = flag; } If i try spawn him without implementing the inteface its work with no problems. This is the interface. Code (Text): public interface ICustomEntity { public GBrain getBrain(); public void setBrain(GBrain brain); public void clearPathfinders(); public GEntityDefinition getDefinition(); public void setDefinition(GEntityDefinition definition); public boolean getSunBurn(); public void setSunBurn(boolean flag); } This is used to spawn an entity in world. Code (Text): net.minecraft.server.v1_11_R1.Entity entity = (net.minecraft.server.v1_11_R1.Entity) ReflectionUtils.getConstructor(entityClass, World.class).newInstance(nmsWorld); entity.setLocation(x,y,z,yaw,pitch); nmsWorld.addEntity(entity, CreatureSpawnEvent.SpawnReason.CUSTOM); Can anyone please help me ? Thanks for help, HamAndRock.
And the problem is exactly what? all i could recognize is that you have a problem with your interface but you haven't mentioned any errors or similar.
Sorry, for late answear the problem occurs when i try to add entity to the nmsWorld. It throws Nullpointer Exception. If i dont implement the interdace it works without problems, but i need to implement it.
This occurs only when i implement the interface to the custom entity class.
