Subject: [PATCH] Add SentientNPC Interface to Entities
|
|
|
|
Used to determine ACTUAL Living NPC's. Spigot mistakenly inversed the conditions for LivingEntity, and
|
|
used LivingEntity for Insentient Entities, and named the actual EntityLiving class EntityInsentient.
|
|
|
|
This should of all been inversed on the implementation side. To make matters worse, Spigot never
|
|
exposed the differentiator that there are entities with AI that are not sentient/alive such as
|
|
Armor stands and Players are the only things that do not implement the REAL EntityLiving class (named Insentient internally)
|
|
|
|
This interface lets you identify NPC entities capable of sentience, and able to move about and react to the world.
