UE5 - Shuffle an Array Using RandomStream
RandomStream is a super useful tool in Unreal Engine for generating reproducible random numbers from a single seed. But it doesn't come out of the box with a way to shuffle an array (or vector, or other random-access container). Here I show how to adapt it to the C++11 Uniform Random Bit Generator named requirement so that it can be used directly with C++11's std::shuffle algorithm. Hope you enjoy weeds, because we'll be diving into some.
