Functions
void	SetbSubtitlesForcedOff (bool Value)
	Flag for forcibly disabling subtitles even if you try to turn them back on they will be off.
void	SetbCanBlueprintsTickByDefault (bool Value)
	Controls whether Blueprint subclasses of actors or components can tick by default.
void	SetbOptimizeAnimBlueprintMemberVariableAccess (bool Value)
	Controls whether anim blueprint nodes that access member variables of their class directly should use the optimized path that avoids a thunk to the Blueprint VM. This will force all anim blueprints to be recompiled.
void	SetbAllowMultiThreadedAnimationUpdate (bool Value)
	Controls whether by default we allow anim blueprint graph updates to be performed on non-game threads. This enables some extra checks in the anim blueprint compiler that will warn when unsafe operations are being attempted. This will force all anim blueprints to be recompiled.
void	SetbSmoothFrameRate (bool Value)
	Whether to enable framerate smoothing.
void	SetbUseFixedFrameRate (bool Value)
	Whether to use a fixed framerate.
void	SetbSubtitlesEnabled (bool Value)
	Flag for completely disabling subtitles for localized sounds.

Detailed Description

Abstract base class of all Engine classes, responsible for management of systems critical to editor or game systems. Also defines default classes for certain engine systems.

Member Function Documentation

◆ SetbAllowMultiThreadedAnimationUpdate()

void SetbAllowMultiThreadedAnimationUpdate ( bool Value )

Controls whether by default we allow anim blueprint graph updates to be performed on non-game threads. This enables some extra checks in the anim blueprint compiler that will warn when unsafe operations are being attempted. This will force all anim blueprints to be recompiled.

◆ SetbCanBlueprintsTickByDefault()

void SetbCanBlueprintsTickByDefault ( bool Value )

Controls whether Blueprint subclasses of actors or components can tick by default.

Blueprints that derive from native C++ classes that have bCanEverTick=true will always be able to tick Blueprints that derive from exactly AActor or UActorComponent will always be able to tick Otherwise, they can tick as long as the parent doesn't have meta=(ChildCannotTick) and either bCanBlueprintsTickByDefault is true or the parent has meta=(ChildCanTick)

◆ SetbOptimizeAnimBlueprintMemberVariableAccess()

void SetbOptimizeAnimBlueprintMemberVariableAccess ( bool Value )

Controls whether anim blueprint nodes that access member variables of their class directly should use the optimized path that avoids a thunk to the Blueprint VM. This will force all anim blueprints to be recompiled.

◆ SetbSmoothFrameRate()

void SetbSmoothFrameRate ( bool Value )

Whether to enable framerate smoothing.

◆ SetbSubtitlesEnabled()

void SetbSubtitlesEnabled ( bool Value )

Flag for completely disabling subtitles for localized sounds.

◆ SetbSubtitlesForcedOff()

void SetbSubtitlesForcedOff ( bool Value )

Flag for forcibly disabling subtitles even if you try to turn them back on they will be off.

◆ SetbUseFixedFrameRate()

void SetbUseFixedFrameRate ( bool Value )

Whether to use a fixed framerate.
