### Summary
Adds `XInRangeByDistance` and `XInBoundsByDistance` methods to `Map.cs`:
**Item Distance Enumeration:**
```cs
ItemDistanceEnumerable<Item> GetItemsInRangeByDistance(Point3D p);
ItemDistanceEnumerable<Item> GetItemsInRangeByDistance(Point3D p, int range);
ItemDistanceEnumerable<T> GetItemsInRangeByDistance<T>(Point3D p) where T : Item;
ItemDistanceEnumerable<T> GetItemsInRangeByDistance<T>(Point3D p, int range) where T : Item;
ItemDistanceEnumerable<Item> GetItemsInRangeByDistance(Point2D p);
ItemDistanceEnumerable<Item> GetItemsInRangeByDistance(Point2D p, int range);
ItemDistanceEnumerable<T> GetItemsInRangeByDistance<T>(Point2D p) where T : Item;
ItemDistanceEnumerable<T> GetItemsInRangeByDistance<T>(Point2D p, int range) where T : Item;
ItemDistanceEnumerable<Item> GetItemsInRangeByDistance(int x, int y, int range);
ItemDistanceEnumerable<T> GetItemsInRangeByDistance<T>(int x, int y, int range) where T : Item;
ItemDistanceEnumerable<Item> GetItemsInBoundsByDistance(Rectangle2D bounds, , bool makeBoundsInclusive = false);
ItemDistanceEnumerable<T> GetItemsInBoundsByDistance<T>(Rectangle2D bounds, bool makeBoundsInclusive = false) where T : Item;
```
**Mobile Distance Enumeration:**
```cs
MobileDistanceEnumerable<Mobile> GetMobilesInRangeByDistance(Point3D p);
MobileDistanceEnumerable<Mobile> GetMobilesInRangeByDistance(Point3D p, int range);
MobileDistanceEnumerable<T> GetMobilesInRangeByDistance<T>(Point3D p) where T : Mobile;
MobileDistanceEnumerable<T> GetMobilesInRangeByDistance<T>(Point3D p, int range) where T : Mobile;
MobileDistanceEnumerable<Mobile> GetMobilesInRangeByDistance(Point2D p);
MobileDistanceEnumerable<Mobile> GetMobilesInRangeByDistance(Point2D p, int range);
MobileDistanceEnumerable<T> GetMobilesInRangeByDistance<T>(Point2D p) where T : Mobile;
MobileDistanceEnumerable<T> GetMobilesInRangeByDistance<T>(Point2D p, int range) where T : Mobile;
MobileDistanceEnumerable<Mobile> GetMobilesInRangeByDistance(int x, int y, int range);
MobileDistanceEnumerable<T> GetMobilesInRangeByDistance<T>(int x, int y, int range) where T : Mobile;
MobileDistanceEnumerable<Mobile> GetMobilesInBoundsByDistance(Rectangle2D bounds, bool makeBoundsInclusive = false);
MobileDistanceEnumerable<T> GetMobilesInBoundsByDistance<T>(Rectangle2D bounds, bool makeBoundsInclusive = false) where T : Mobile;
```
**Client Distance Enumeration:**
```cs
ClientDistanceEnumerable GetClientsInRangeByDistance(Point3D p);
ClientDistanceEnumerable GetClientsInRangeByDistance(Point3D p, int range);
ClientDistanceEnumerable GetClientsInRangeByDistance(Point2D p);
ClientDistanceEnumerable GetClientsInRangeByDistance(Point2D p, int range);
ClientDistanceEnumerable GetClientsInRangeByDistance(int x, int y, int range);
ClientDistanceEnumerable GetClientsInBoundsByDistance(Rectangle2D bounds, bool makeBoundsInclusive = false);
```
**Example Usage:**
How to use `minDistance` to terminate early when all subsequent mobiles in the iteration will be at an increasing min distance.
```csharp
var playerLocation = player.Location;
const int maxRange = 100;
const int maxMobiles = 12;
var closestMobiles = new SortedSet<Mobile>(Comparer<Mobile>.Create((x, y) =>
{
var distX = x.GetDistanceToSqrt(playerLocation);
var distY = y.GetDistanceToSqrt(playerLocation);
int result = distX.CompareTo(distY);
if (result == 0)
{
result = (x?.Serial ?? Serial.MinusOne).CompareTo(y?.Serial ?? Serial.MinusOne);
}
return result;
}));
int lastMinDistance = 0;
foreach (var (mobile, minDistance) in map.GetMobilesInRangeByDistance(playerLocation, maxRange))
{
// Stop if we have enough and distance starts increasing
if (closestMobiles.Count >= maxMobiles && minDistance > lastMinDistance)
{
break;
}
closestMobiles.Add(mobile);
lastMinDistance = minDistance;
}
// Results are already ordered by proximity
foreach (var mobile in closestMobiles)
{
var actualDistance = mobile.GetDistanceToSqrt(playerLocation);
Console.WriteLine($"{mobile.Name}: ActualDist={actualDistance:F2}");
}
```
