Description
Returns a randomly selected element from an array.
RandomFrom returns a randomly selected element from the array passed as the AValues argument. In C++, AValues_Size is the index of the last array element (one less than the number of elements.)
To initialize the random number generator, add a single call Randomize or assign a value to the RandSeed variable before making any calls to RandomFrom.
