Strange Random Location Pattern

Development Programming & Scripting C++

I am trying to create a stream of (pseudo) random locations. I am using the FRandomStream with a seed that is incremented every time a new object is spawned. When I spawn many objects a diagonal pattern starts to emerge (see image). This makes me believe that there is some constant relation between the first and second items retrieved from the RandomStream, even though a different seed is used every time. Can someone explain me why this happens and possible provide a workaround? Thanks!

The pattern:

Here some (simplified) code I use:




for (int32 i = 0; i < 100; i++)
    {
        // Create RandomStream
        FRandomStream RandomStream;

        // Set Random stream Seed to i
        RandomStream.Initialize(i);

        // Get 2 random floats
        float randx = RandomStream.FRandRange(0.f, 100.f);
        float randy = RandomStream.FRandRange(0.f, 100.f);

        // Create a random spam locations based on the random floats
        FVector RandomSpawnLocation = FVector::FVector(randx, randy, 0.f);

        // Spawn the object
        GetWorld()->SpawnActor<T>(RandomSpawnLocation);
    }

Thank you for your time! :rolleyes:
