AActor::ShouldTickIfViewportsOnly
#include "GameFramework/Actor.h"
Access: public
Specifiers: virtualENGINE_API
Description
Returns whether this actor should tick in editor viewports (TickType == LEVELTICK_ViewportsOnly). Override and return true to enable editor-time previews that require a tick.
Caveats & Gotchas
- • The default implementation returns false for regular actors, so Tick() is not called in the editor unless you override this. Actors like camera preview actors override it to return true.
- • Even when this returns true, ticking in viewports still respects bCanEverTick and tick enable state — it is an additional gate, not a full bypass.
- • This is only relevant in editor contexts. In a shipping build, TickType never equals LEVELTICK_ViewportsOnly.
