Syntax

class FAssetTypeActions_Base : public IAssetTypeActions

Remarks

A base class for all AssetTypeActions. Provides helper functions useful for many types. Deriving from this class is optional.

Functions

	Name	Description
void	CreateUniqueAssetName ( const FString& InBasePackageName, const FString& InSuffix, FString& OutPackageName, FString& OutAssetName )	Creates a unique package and asset name taking the form InBasePackageName+InSuffix
FString	DumpAssetToTempFile ( UObject* Asset )	Util for dumping an asset to a temporary text file. Returns absolute filename to temp file
TArray< T &#...	GetTypedObjectPtrs ( const TArray< UObject* >& InO... )
TArray< TWea...	GetTypedWeakObjectPtrs ( const TArray< UObject* >& InO... )	Helper function to convert the input for GetActions to a list that can be used for delegates

Overridden from IAssetTypeActions

	Name	Description
bool	AssetsActivatedOverride ( const TArray< UObject* >& InO..., EAssetTypeActivationMethod::Type Ac... )	Allows overriding asset activation to perform asset type specific activation for the supplied assets.
void	BuildBackendFilter ( FARFilter& InFilter )	Builds the filter for this class
bool	CanFilter()	Returns true if this class can be used as a filter in the content browser
bool	CanLocalize()	Returns true if this class can be localized
bool	CanMerge()	Returns true if this class can be merged (either manually or automatically)
void	GetActions ( const TArray< UObject* >& InO..., FMenuBuilder& MenuBuilder )	Generates a menubuilder for the specified objects.
void	GetActions ( const TArray< UObject* >& InO..., FToolMenuSection& Section )	Generates a menu section for the specified objects.
FText	GetAssetDescription ( const FAssetData& AssetData )	Returns additional tooltip information for the specified asset, if it has any (otherwise return the null widget)
EThumbnailPr...	GetDefaultThumbnailPrimitiveType ( UObject* Asset )	Returns the default thumbnail type that should be rendered when rendering primitive shapes.
FText	GetDisplayNameFromAssetData ( const FAssetData& AssetData )	Optionally gets a class display name for this asset (otherwise, returns empty text (e.g. `FText::GetEmpty()_)
FString	GetObjectDisplayName ( UObject* Object )	Returns the display name for that object.
void	GetResolvedSourceFilePaths ( const TArray< UObject* >& Typ..., TArray< FString >& OutSourceFilePa... )	Collects the resolved source paths for the imported assets
void	GetSourceFileLabels ( const TArray< UObject* >& Typ..., TArray< FString >& OutSourceFileLa... )	Collects the source file labels for the imported assets
const TArray...	GetSubMenus()	Returns array of sub-menu names that this asset type is parented under in the Asset Creation Context Menu.
UThumbnailIn...	GetThumbnailInfo ( UObject* Asset )	Returns the thumbnail info for the specified asset, if it has one.
TSharedPtr< ...	GetThumbnailOverlay ( const FAssetData& AssetData )	Optionally returns a custom widget to overlay on top of this assets' thumbnail
TArray< FAss...	GetValidAssetsForPreviewOrEdit ( TArrayView< const FAssetData > InAs..., bool bIsPreview )	Returns the set of asset data that is valid to load.
bool	HasActions ( const TArray< UObject* >& InO... )	Returns true if this class can supply actions for InObjects.
bool	IsImportedAsset()	Returns whether the asset was imported from an external source
bool	IsSupported()	Is this asset type supported in the current session?
void	Merge ( UObject* InObject )	Begins a merge operation for InObject (automatically determines remote/base versions needed to resolve)
void	Merge ( UObject* BaseAsset, UObject* RemoteAsset, UObject* LocalAsset, const FOnMergeResolved& Resolution... )	Begins a merge between the specified assets
void	OpenAssetEditor ( const TArray< UObject* >& InO..., TSharedPtr< class IToolkitHost > Ed... )	Opens the asset editor for the specified objects.
void	PerformAssetDiff ( UObject* OldAsset, UObject* NewAsset, const FRevisionInfo& OldRevision, const FRevisionInfo& NewRevision )	Performs asset-specific diff on the supplied asset
void	SetSupported ( bool bInSupported )	Sets whether or not this asset type is a supported type for this editor session.
bool	ShouldForceWorldCentric()

Deprecated Functions

		Name	Description
	void	AssetsActivated ( const TArray< UObject* >& InO..., EAssetTypeActivationMethod::Type Ac... )	Use AssetsActivatedOverride instead to provide any non-default behavior. Using AssetsActivatedOverride, you no longer need a call to FAssetTypeActions_Base::AssetsActivated.
