Function Documentation

ComponentTypeCouldHaveUVs()

bool ToolBuilderUtil::ComponentTypeCouldHaveUVs

(

const UActorComponent &

Component

)

Determine if component support UVs.

CountActors()

int32 ToolBuilderUtil::CountActors	(	const FToolBuilderState &	InputState,
		const TFunction< bool(AActor *)> &	Predicate
	)

Count number of selected Actors that pass predicate.

CountComponents()

int ToolBuilderUtil::CountComponents	(	const FToolBuilderState &	InputState,
		const TFunction< bool(UActorComponent *)> &	Predicate
	)

Count number of selected components that pass predicate. If Component selection is not empty, returns that count, otherwise counts in all selected Actors

CountSelectedActorsOfType()

template<typename ActorType >

int ToolBuilderUtil::CountSelectedActorsOfType

(

const FToolBuilderState &

InputState

)

Count number of selected Actors of given type.

CountSelectedComponentsOfType()

template<typename ComponentType >

int ToolBuilderUtil::CountSelectedComponentsOfType

(

const FToolBuilderState &

InputState

)

Count number of components of given type. If Component selection is not empty, returns that count, otherwise counts in all selected Actors

EnumerateComponents()

void ToolBuilderUtil::EnumerateComponents	(	const FToolBuilderState &	InputState,
		TFunctionRef< void(UActorComponent *)>	ComponentFunc
	)

FindAllActors()

TArray< AActor * > ToolBuilderUtil::FindAllActors	(	const FToolBuilderState &	InputState,
		const TFunction< bool(AActor *)> &	Predicate
	)

First all Actors that pass predicate. Searches Actors selection list.

FindAllComponents()

TArray< UActorComponent * > ToolBuilderUtil::FindAllComponents	(	const FToolBuilderState &	InputState,
		const TFunction< bool(UActorComponent *)> &	Predicate
	)

First all components that passes predicate. Searches Components selection list first, then all Actors

FindFirstActor()

AActor * ToolBuilderUtil::FindFirstActor	(	const FToolBuilderState &	InputState,
		const TFunction< bool(AActor *)> &	Predicate
	)

First first available Actor that passes predicate. Searches Actors selection list.

FindFirstActorOfType()

template<typename ActorType >

ActorType * ToolBuilderUtil::FindFirstActorOfType

(

const FToolBuilderState &

InputState

)

Find first first available Actor of given type, or return nullptr if not found

FindFirstComponent()

UActorComponent * ToolBuilderUtil::FindFirstComponent	(	const FToolBuilderState &	InputState,
		const TFunction< bool(UActorComponent *)> &	Predicate
	)

First first available component that passes predicate. Searches Components selection list first, then all Actors

FindFirstComponentOfType()

template<typename ComponentType >

ComponentType * ToolBuilderUtil::FindFirstComponentOfType

(

const FToolBuilderState &

InputState

)

First first available component of given type. Searches Components selection list first, then all Actors

IsVolume()

bool ToolBuilderUtil::IsVolume

(

const UActorComponent &

Component

)

Determine if component is a volume or not.
