Projectile doesn't go towards crosshair's direction!

Yes it’s impossible. Please think about it… The red line and the yellow line. Where do they intersect? Right, at ONE location. That means that only at ONE location your bullet would actually impact under your crosshair. In all the other infinite other points of your yellow line that represents the camera view and thus also the red dot, the bullet would NOT impact under it.

Oh I finally got that. So the intersection point between the yellow and red line is always the same. I got it.

However, this basically is the second half of the LineTrace Method, where you determine what your Character is aiming at by that lineTrace and then you can draw this yellow line from your muzzle to your desired impact location.

Okay now that I got that, I can go further.

This is the code I made, following my logic AND your suggestions

	FVector CameraLoc;
	FRotator CameraRot;
	MyOwner->GetActorEyesViewPoint(CameraLoc, CameraRot);

	FHitResult Hit;
	GetWorld()->LineTraceSingleByChannel(Hit, CameraLoc, CameraLoc + (CameraRot.Vector() * 9000), COLLISION_WEAPON);

	FVector AimDir;

	if (Hit.bBlockingHit)
	{
		AimDir = Hit.Location - MyOwner->GetMesh()->GetSocketLocation((FName("WeaponSocket")));
		AimDir.Normalize();
	}

        else
        {
             // in this case, AimDir is undefined!
        }

	FTransform SpawnTM(MyOwner->GetMesh()->GetSocketLocation((FName("WeaponSocket"))));

	AProjectile* Projectile = Cast<AProjectile>(UGameplayStatics::BeginDeferredActorSpawnFromClass(this, ProjectileClass, SpawnTM));

	if (Projectile)
	{
		Projectile->Instigator = Instigator;
		Projectile->SetOwner(this);
		Projectile->InitVelocity(AimDir);

		UGameplayStatics::FinishSpawningActor(Projectile, SpawnTM);
	}

What’s the problem with this code?**

#1
The projectile doesn’t go forward. It goes backwards, in the opposite direction rather than where I aimed!

Yes, I made sure I shot something within 9000 centimeters…

#2 - (this is secondary for now, the bug num#1 is the most intimidating for now!)
AimDir, as you said, CAN be undefined if nothing is hit by the LineTrace. How do I make my projectile start and go towards my crosshair, even if I aimed at the sky?
