AActor::CreateComponentFromTemplateData

function Engine Since 4.15

#include "GameFramework/Actor.h"

Access: public

Description

Creates a component instance from pre-cooked serialized data, allowing Blueprint component construction to bypass the more expensive template duplication path used in the editor.

Caveats & Gotchas

• This fast path is only valid in cooked builds; in non-cooked (editor) builds the engine falls back to CreateComponentFromTemplate automatically.
• The FBlueprintCookedComponentInstancingData struct is generated by the Blueprint compiler at cook time — never construct one manually; incorrect data will silently produce a broken component.

Signature

ENGINE_API UActorComponent* CreateComponentFromTemplateData(const struct FBlueprintCookedComponentInstancingData* TemplateData, const FName InName = NAME_None);

Parameters

Name	Type	Description	Default
TemplateData	const struct FBlueprintCookedComponentInstancingData*	Pre-cooked instancing data generated at cook time to fast-path component creation.	—
InName	const FName	Desired name for the new component instance.	NAME_None

Return Type

UActorComponent*

Example

Called automatically by the Blueprint VM at runtime C++

// This is called by Blueprint construction script machinery.
// You will not call it directly in game code.
// Understanding when it runs:
// - Editor builds: CreateComponentFromTemplate is used instead
// - Cooked builds: this function is called for faster spawn times
