NPC Logics
The logic pertaining to the initialization, behaviors, and maintenance of NPC characters (pinatas, helpers, etc.)
APooledCharacter
APooledCharacter is mainly responsible for handling the pooling logic for the characters that use it and properly handle instances that aren't pooled.
Inherits from class: ACharacter
Implements interfaces: IPoolable, IEventListener
Important Variables to Know
This isn' all of the variables that are present but are some that are very important to the APooledCharacter's functionality:
int64 SoulID: A unique identifier for an NPC. This number is used to find the correct data associated with that NPC, so if you give the APooledCharacter a SoulID number, you will always get that "soul" (if it exists). Think of it like the equivalent of an American Social Security Number.
int32 DefinitionID: The order that the DefinitionData is in its corresponding database. It refers to general information about an NPC type, but not to a specific instance of that type (that would be SoulID). Think about this as the "species" that the APooledCharacter will become.
bool bIsUsed: Is this instance of APooledCharacter currently in use? Unused instances can be given the data needed to become an NPC while not overriding an instance that's already in use.
bool bUsingPooledMethod: Determines whether or not this instance of APooledCharacter is actually part of a pool. Instances that are in a pool are re-used so that we don't have to constantly create and destroy APooledCharacter instances, which can boggle down performance if left unchecked.
Initialise (yes, we know it's misspelled here)
At this level the initialize function is a lightweight function; all it does is sets the value of the APooledCharacter's soul and DefinitionDataID (as seen in Initialise_Implementation). The child blueprints need to use the NPCType variable to find the correct definition database that the DefinitionDataID references. When overriding this function in blueprint, ensure that it has a call to its parent function so that the variables are properly set.
SetUsed
SetUsed tells the APooledCharacter instance whether or not it is being used. If the instance is part of a pool, it enables/disables the ActorTick, collision, and visibility, then either begins or ends using the APooledCharacter (more on that later). If the APooledCharacter is NOT part of a pool, then it either begins using the instance or destroys it.
