Enumeration Type Documentation

EDynamicResolutionStatus

enum class EDynamicResolutionStatus

strong

Status of dynamic resolution that depends on project setting cvar, game user settings, and pause

Enumerator
Unsupported
Disabled
Paused
Enabled
DebugForceEnabled

EFullyLoadPackageType

enum EFullyLoadPackageType : int

Enumerates types of fully loaded packages.

Enumerator
FULLYLOAD_Map	Load the packages when the map in Tag is loaded.
FULLYLOAD_Game_PreLoadClass	Load the packages before the game class in Tag is loaded. The Game name MUST be specified in the URL (game=Package.GameName). Useful for loading packages needed to load the game type (a DLC game type, for instance).
FULLYLOAD_Game_PostLoadClass	Load the packages after the game class in Tag is loaded. Will work no matter how game is specified in UWorld::SetGameMode. Useful for modifying shipping gametypes by loading more packages (mutators, for instance).
FULLYLOAD_Always	Fully load the package as long as the DLC is loaded.
FULLYLOAD_Mutator	Load the package for a mutator that is active.
FULLYLOAD_MAX

EGarbageCollectionType

enum class EGarbageCollectionType

strong

Type of UObject purge type to be performed by the engine

Enumerator
None
Incremental
Full

EGetWorldErrorMode

enum class EGetWorldErrorMode

strong

Enumerator
ReturnNull

Assert

ETransitionType

enum class ETransitionType : uint8

strong

Enumerates transition types.

Enumerator
