示例1: Arbitrary
//Executes various different heightmap forming functions at random
public static Heightmap Arbitrary(SortedList<double, Action> functions, int iterations = 10000, Func<int, bool> StepCallback = null)
{
//Want to make sure that they're sorted in descending order and normalized.
double total = functions.Aggregate<KeyValuePair<double, Action>, double>(0, (current, next) => current + next.Key);
var actionsSorted = (from kvp in functions select new {Key = kvp.Key/total,
Value = kvp.Value}).OrderBy((x)=>x.Key);
List<int> actionsDone = new List<int>(functions.Count);
for (int i = 0; i < functions.Count; i++)
{
actionsDone.Add(0);
}
for (int i = 0; i < iterations; i++)
{
//try to "roll under" the key value; we perform the first action whose key + cumulative value is higher than this value.
double randomValue = rand.NextDouble();
double cumulativeValue = 0;
for(int j = 0; j < actionsSorted.Count(); j++)
{
var kvp = actionsSorted.ElementAt(j);
cumulativeValue += kvp.Key;
if (randomValue < cumulativeValue)

if (StepCallback != null)
