AActor::SetActorHiddenInGame

function Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: virtualUFUNCTIONBlueprintCallable

Description

Hides or shows the actor and all of its components in the game world. Does not affect collision or tick — a hidden actor still receives ticks and collides normally unless you also disable those.

Signature

virtual void SetActorHiddenInGame(bool bNewHidden)

Parameters

Name	Type	Description	Default
bNewHidden	bool	Whether to hide the actor and all its components.	—

Return Type

void

Caveats & Gotchas

• Hidden actors still tick and collide. If you want to fully deactivate an actor, also call SetActorEnableCollision(false) and SetActorTickEnabled(false).
• This sets bHidden on the actor. Individual components can override visibility independently via USceneComponent::SetVisibility.
• Does not affect visibility in the editor viewport — use SetIsTemporarilyHiddenInEditor for that.

Example

Hide and disable an actor C++

// Hide visually and disable collision, but keep ticking
SetActorHiddenInGame(true);
SetActorEnableCollision(false);
