IsYielding()

bool UInkThread::IsYielding

(

)

Checks if the thread is stopped.

Return values

true	if the thread currently waiting to resume

Return Value

OnChoice()

void UInkThread::OnChoice

(

const TArray< UInkChoice * > &

choices

)

triggered when reached a choice point.

Parameters

choices

possible branches to choose from, in order to continue

OnLineWritten()

void UInkThread::OnLineWritten	(	const FString &	line,
		const UTagList *	tags )

triggered if a new line of context is available

Parameters

line	text of new line
tags	tags associated with this line

Event OnLineWritten

Line

Tags

OnShutdown()

void UInkThread::OnShutdown

(

)

triggered when the thread reached the end of context

AInkRuntime::StartExisting()

Event OnShutdown

OnStartup()

void UInkThread::OnStartup

(

)

triggered after initializing the runner

Event OnStartup

OnTag()

void UInkThread::OnTag

(

const FString &

tag_name

)

triggered when a tag is encountered

Parameters

tag_name

the tag found

Event OnTag

Tag name

PickChoice()

bool UInkThread::PickChoice

(

int

index

)

picks a choice to continue with

See also

UInkChoice::GetIndex()

Return values

false

if the index is out of range

Return Value

RegisterExternalEvent()

void UInkThread::RegisterExternalEvent	(	const FString &	functionName,
		const FExternalFunctionVoidDelegate &	function,
		bool	lookaheadSafe = false )

RegisterExternalFunction()

void UInkThread::RegisterExternalFunction	(	const FString &	functionName,
		const FExternalFunctionDelegate &	function,
		bool	lookaheadSafe = false )

register a external function.

A function provides a return value

RegisterTagFunction()

void UInkThread::RegisterTagFunction	(	FName	functionName,

Register a callback for a named "tag function".

Resume()

void UInkThread::Resume

(

)

Resumes yielded thread.

See also

Yield()

Resume

Target

Stop()

void UInkThread::Stop

(

)

Kills thread at next possible moment.

Stop

Target

Yield()

void UInkThread::Yield

(

)

Yields the thread immediately.

This will stop the execution (after finishing the current line). until Resume() is called.

Yield() and Resume() working with a reference counter. therefore a thread can be yield multiple times, and must then be resumed the same amount.
