Projectile collides with Character when shooting upwards!

I forgot to mention that I was using a custom trace channel instead of the predefined ones such as “visibility”. The engine channels work fine for me at least, however using custom channels in C++ just causes the trace to return true half of the time. I do know that it is not my setting up of the channel as blueprints work flawlessly.

I took a closer look at your code. I did see you used a function “WeaponTrace” to set your hit result “Impact” instead of a one-liner trace. Could you post the WeaponTrace function here as well as your current weapon code if it’s different than your OP. If you’re using anything other than a trace by channel for a weapon, I suggest you try that out if you have not already as well.

I’m using a custom line trace channel too.

FHitResult APAWeapon::WeaponTrace(const FVector& StartPlug, const FVector& EndPlug, const TArray<AActor*>& IgnoreActors) const
{
    static FName WeaponFireTag = FName(TEXT("WeaponTrace"));

    // Perform trace to retrieve hit info
    FCollisionQueryParams TraceParams(WeaponFireTag, true, Instigator);
    TraceParams.bTraceAsyncScene = true;
    TraceParams.bReturnPhysicalMaterial = true;
    TraceParams.AddIgnoredActors(IgnoreActors);

    FHitResult Hit(ForceInit);
    GetWorld()->LineTraceSingleByChannel(Hit, StartPlug, EndPlug, COLLISION_WEAPON, TraceParams);

    return Hit;
}
