I have set it up like this

	World->LineTraceMultiByChannel(MultiHit, StartTrace, EndTraceSpread, ECC_Visibility, Params);

	TArray<FHitResult> MultiHit;

When i hit my enemies how do i get the actors from the array so i can apply damage? This is how i did it before when i used a single line trace but i dont know how to do it with a multi trace.

	if (Hit.Actor != NULL) {
		if (Hit.GetActor()->ActorHasTag("Enemy")) {
			UE_LOG(LogTemp, Warning, TEXT("Hit"))

When dealing with arrays you will have to use a for loop to loops through the array.
