Set Actor Location not working, but working only when I am in Air!

[bennur_1206]

Set Actor Location only happens in air (example jump), not when I am walking on ground.

I am using Gameplay Ability System (I hate it) and sending target data to “blink” to:

void UGA_BLINK::perform_ability(const FGameplayAbilitySpecHandle Handle, const FGameplayAbilityActorInfo * ActorInfo, const FGameplayAbilityActivationInfo ActivationInfo, const FGameplayEventData * TriggerEventData)
{
	if (!(ActorInfo->AvatarActor.Get())) return;

	AActor * avatar_actor_ = ActorInfo->AvatarActor.Get();

	// Server: Receive Target Data from client
	// if (ActorInfo->IsNetAuthority())
	if (HasAuthority(&ActivationInfo))
	{
		if (ActorInfo->IsLocallyControlled())
		{
			avatar_actor_->SetActorLocation(
				get_target_data(avatar_actor_).Location
			);

			EndAbility(Handle, ActorInfo, ActivationInfo, true, false);
			return;
		}

		ActorInfo->AbilitySystemComponent.Get()
			->AbilityTargetDataSetDelegate(
				Handle,
				ActivationInfo.GetActivationPredictionKey()
			)
				.AddLambda(		// Binding Listener handler
					[this, avatar_actor_, Handle, ActorInfo, ActivationInfo]
						(const FGameplayAbilityTargetDataHandle& Data, FGameplayTag Tag)
					{
						if (!(
							// Data.IsValid(0) && 
							Data.Get(0) && 
							Data.Get(0)->GetHitResult()
						))
						{
							CancelAbility(Handle, ActorInfo, ActivationInfo, true);
							return;
						}

						GEngine->AddOnScreenDebugMessage(
							-1,
							5.0f,
							FColor::Emerald,
							FString::Printf(
								TEXT("BLINK >>> %s: Moving %s to %s"),
								HasAuthority(&ActivationInfo) ? TEXT("SERVER") : TEXT("CLIENT"),
								*avatar_actor_->GetName(),
								*Data.Get(0)->GetHitResult()->Location.ToString()
							)
						);

						// Set Actor Location
						avatar_actor_->SetActorLocation(Data.Get(0)->GetHitResult()->Location);

						EndAbility(Handle, ActorInfo, ActivationInfo, true, false);
					}
				);
	}
	else
	{
		// Client/Server: Send Target Data to server
		FScopedPredictionWindow ScopedPrediction(ActorInfo->AbilitySystemComponent.Get());

		FGameplayAbilityTargetDataHandle DataHandle;
		FGameplayAbilityTargetData_SingleTargetHit * Data = new FGameplayAbilityTargetData_SingleTargetHit();
		Data->HitResult = get_target_data(avatar_actor_);
		DataHandle.Add(Data);

		GEngine->AddOnScreenDebugMessage(
			-1,
			5.0f,
			FColor::Emerald,
			FString::Printf(
				TEXT("BLINK >>> %s: sending target location"),
				HasAuthority(&ActivationInfo) ? TEXT("SERVER") : TEXT("CLIENT")
			)
		);

		ActorInfo->AbilitySystemComponent.Get()
			->ServerSetReplicatedTargetData(
				Handle,
				ActivationInfo.GetActivationPredictionKey(),
				DataHandle,
				TriggerEventData->EventTag,
				ActorInfo->AbilitySystemComponent.Get()->ScopedPredictionKey
			);

		EndAbility(Handle, ActorInfo, ActivationInfo, true, false);
	}
}

The client sends data to server. But the client only blinks to location when in Air!

Same thing with the server, where I am not listening for target data and simply setting Actor Location. Server only sets actor location when in Air.

What am I doing wrong? Please help!

Ok, it is now working! I used draw debug to see where the hit location was.

Turns out, when actor landed, the debug collision drew around the actor, with start-end locations being actor - Camera range location.

So when character landed, the capsule trace updated the hit location to actor location due to camera trace collision with the ground!
