To click on an actor you can use the GetHusResultUnderCursor() function inside the player controller

AActor* AAnswerhubProject::GetActorFromMouse()
{
	//Get a reference to the player controller
	APlayerController* pc = GetWorld()->GetFirstPlayerController();

	FHitResult hit;

	//Attempt to hit an object underneath the mouse cursor with the Trace Collision Channel. 
	pc->GetHitResultUnderCursor(ECC_GameTraceChannel1, true, hit);

	return hit.GetActor();
}

Once you get the clicked actor you can call your function.

Usage example:

AYourActorClass * clickedActor = Cast<AYourActorClass>(GetActorFromCursor());

if(IsValid(clickedActor))
{
	clickedActor->YourFunction();
}

That should do the trick.

Good luck.
