UAssetManager::LoadPrimaryAssetsWithType

function Engine Since unknown

#include "Engine/AssetManager.h"

Access: public Specifiers: virtual

Description

Loads every primary asset registered under a given type and bundle set, useful for bulk-loading a whole asset category such as during cooking or level warm-up.

Caveats & Gotchas

• Loads every asset currently registered under that type, which can pull in an uncontrolled amount of memory if the type contains many assets — prefer LoadPrimaryAssets with an explicit list for user-facing content.
• Only picks up assets that have already been scanned into the directory; assets registered dynamically afterward are not included in this call.

Signature

virtual TSharedPtr<FStreamableHandle> LoadPrimaryAssetsWithType(
	FPrimaryAssetType PrimaryAssetType,
	const TArray<FName>& LoadBundles = TArray<FName>(),
	FStreamableDelegate DelegateToCall = FStreamableDelegate(),
	TAsyncLoadPriority Priority = FStreamableManager::DefaultAsyncLoadPriority,
	UE::FSourceLocation Location = UE::FSourceLocation::Current());

Parameters

Name	Type	Description	Default
PrimaryAssetType	FPrimaryAssetType	The primary asset type whose registered assets should all be loaded.	—
LoadBundles	const TArray<FName>&	Bundles to load for each asset in addition to its default state.	TArray<FName>()
DelegateToCall	FStreamableDelegate	Delegate invoked on completion.	FStreamableDelegate()
Priority	TAsyncLoadPriority	Async loading priority for the request.	FStreamableManager::DefaultAsyncLoadPriority
Location	UE::FSourceLocation	Call-site source location captured for streaming diagnostics; not meant to be passed explicitly.	UE::FSourceLocation::Current()

Return Type

TSharedPtr<FStreamableHandle>

Example

	FPrimaryAssetType("Map"),
