EventFlow Functions

EventFlow scripts call functions implemented by the game. The function registry contains 1,255 action handlers and 959 query handlers, including functions not declared in EventFlow scripts. Actions perform work and signal completion; queries return an integer used by a Switch event.

Each entry lists the handler name or hash, supported actors, and aliases. Reconstructed name marks an inferred name; unnamed handlers are identified by their registered hash in this reference.

Actors and supported functions

The game assigns each actor a category and creates the action and query handlers supported by that category. Multiple categories can expose the same handler, so the counts below overlap.

Actor group	Script actor names	Actions	Queries
Player	Player	96	26
NPC	MainNpc, SubNpc, Npc_1 through Npc_5, and DynamicCast_* NPC bindings	346	323
EventFlowSystemActor	EventFlowSystemActor	820	611
Ftr	Ftr	16	8
SnowMan	SnowMan	3	8
GeneralObject	GeneralObject	2	6
HaniwaKun	HaniwaKun	1	1

These are function-support categories, rather than a list of individual villagers or furniture items. A script actor is bound to an actual game object when a flow runs. Names beginning with DynamicCast_ select NPC bindings dynamically; they do not introduce another function category.

An actor’s secondary name distinguishes separate bindings of the same primary actor. For example, EventFlowSystemActor[BgmActor] and EventFlowSystemActor[NetActor] share the system actor’s supported functions. The text in brackets represents the secondary name, rather than part of the primary actor name.

Names, aliases, and hashes

An event first selects an actor and an action/query entry by their local array indices in the BFEVFL. The game then resolves the name to a handler using a 32-bit MurmurHash3 hash, with seed zero. The hash in this catalog identifies the registered handler; it is separate from the event’s local function index. Actions and queries use separate registries.

EventFlow/Info/BindInfo.byml supplies aliases through ActionBindData and QueryBindData. Several names can resolve to one handler. The catalog places aliases beneath the handler name and includes them in searches. Hashes identify registered handler names; hashing an alias directly can produce a different value.

Function catalog

Select an actor group to list its supported actions and queries. Search by name, alias, hash, or behavior. Unnamed entries display their handler hash in place of a name.

Dispatcher special cases

Some action names are handled directly by the flow dispatcher, outside the action factory registry:

Name	Behavior
EventFlowActionExitFlowchart	Requests that the flowchart exit.
EventFlowActionDummy	Completes immediately.

EventFlowActionReleaseVersionFile is declared by scripts but has no matching factory-registry entry. It is excluded from the registered-handler counts above; its behavior is not specified here.
