Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

BP to C++ Fire Projectile Using LookAtRotation

Hey guys so this is my code. Basically I'm just trying to fire a projectile so it goes to the center of the screen. As far as I can tell this should be working because it Compiles just fine and everything, but when I go to fire my weapon the ball only fires in one direction and I logged out the Rotation, and the Rotation never changes. It doesn't matter what direction I'm facing or if the LineTrace hits anything or not. Any ideas would be greatly appreciated.

include "Kismet/KismetMathLibrary.h"

 Void AActor:OnFire();
 Float Distance = 10000.0f;
 FHitResult Hit;
 FVector Start = FirstPersonCameraComponent->GetComponentLocation();
 FVector End = Start + (FirstPersonCameraComponent->GetForwardVector()* Distance);
 FRotator SpawnRotation = UKismetMathLibrary::FindLookatRotation(FP_MuzzleLocation->GetComponentLocation(), Hit.TraceEnd);
 FVector SpawnLocation = FP_MuzzleLocation ->GetComponentLocation() + SpawnRotation.RotateVector(GunOffset);
  FActorSpawnParameters ActorSpawnParams;
 ActorSpawnParams.SpawnCollisionHandlingOveride = ESpawnActorCollisionHandlingMethod::AdjustIfPossibleButDontSpawnIfColliding;
 World->SpawnActor<AFirstPersonProjectile>(ProjectileClass, SpawnLocation, SpawnRotation, ActorSpawnParams);
