Why GetOverlappingActors doesn't work

[SoTryHardyOne]

Hello. I neet to write a seeker system that must be closed inside an Actor Component. I want use the GetOverlappingActors and USphereComponent like this guy

Good way to get all actors of given type in radius around main character?

Hello, I’m trying to grab/get all of the actors (with a specific tag) around my main player character (perhaps in an array), and then select/grab/manipulate the closest actor with that given tag in C++. I don’t know if I should do this using physics/collisions with something like a simple sphere collision sweep? I also have seen the “GetAllActorsOfClass” function, but that seems a bit unnecessary for my needs. The only problem I have with sweeping a sphere shape from say above my character d…

but it doesn’t work and the array is always empty

I think I see the issue. You need to set Generate Overlap Events to true on both components that are overlapping to generate an event.

You can set it with this function:

UPrimitiveComponent::SetGenerateOverlapEvents

In my game, I cache all of the things that I want to test against before the level starts and then do a distance check over the array of actors. I find that way to be simpler.
