Can you control the rarity/randomness of a certain terrain definition (i.e. gold mines/hexes higher rarity).
Am I missing it or can I suggest this feature? Maybe an upper/lower limit for types?

I haven't seen anything like that in it, but you can script your own procedural generator:
1) In CameraController.cs at line 140 you would replace the World.GetInstance().Initialize(); line with the call to your generator.
2) Your generator would work something like this:
// Get the world engine and tell it we are preparing to generate
World world = World.instance;
world.status = HoneyFramework.World.Status.Preparation;
// Refresh terrain definitions
TerrainDefinition.ReloadDefinitions();
// Clear out the old hex data
world.hexes = new Dictionary<Vector3i, Hex>();
// Get the hexes we are going to populate
List<Vector3i> rangeHexes = HexNeighbors.GetRange(new Vector3i(), world.hexRadius);
int terrainCount = TerrainDefinition.definitions.Count;
if (terrainCount < 1)
{
Debug.LogError("No terrain definitions to use!");
return;
}
// Add the hex data
Hex hex;
MHTerrain td;
foreach (Vector3i v in rangeHexes)
{
hex = new Hex();
hex.orderPosition = Random.Range(0f, 1f);
hex.rotationAngle = Random.Range(0f, 360f);
// Just grab the first non-sea terrain type
td = MHTerrain.list.First(t => t.seaType == false);
hex.terrainType = TerrainDefinition.definitions.First(t => t.source.OID == td.OID);
hex.position = v;
World.instance.ReadyToPolishHex(hex);
world.hexes.Add(v, hex);
}
RiverFactory.CreateRivers(this, hexRadius);
// Force terrain redraw
for (int x = -world.chunkRadius; x <= world.chunkRadius; x++)
for (int y = -world.chunkRadius; y <= world.chunkRadius; y++)
{
world.PrepareChunkData(new Vector2i(x, y));
}
// Update the status to show the engine is generating the terrain
world.status = HoneyFramework.World.Status.TerrainGeneration;

Nice-yeah. After digging around a bit, I can see how that could be updated to accommodate that.
I've already been modifying TerrainDefinition to allow Lakes and such as well.
Thanks!

Note that if you want to have nice lakes maybe you dont want to have beach around them. You should then play with "SEA" tag. Its used by World Oven to extend sand from under water to nearby areas. You may want to add LAKE tag which would have benefit of the sea tag in most cases but will not get render way in oven .

My first pass was an inverted mountain [pic], which clearly isn't going to work as is.  If it were tagged sea, would the rivers try to end in it as well? As you can see from the pic ![]() they ignore them as normal terrain. I guess I should dig into what the world oven does with sea tags.   |

look in RiverFactory for this line:
if (!world.hexes.ContainsKey(v) || world.hexes[v].terrainType.source.typeList.Contains( GoogleFu.Tags.rowIds.TAG_SEA))

If anyone's interested, I got this working. I used Tango's snippet to create a new "InitializeWithWeight()" method. After adding the weight INT to the MHTerrain data and exposing it in the inspector, I run through the weights (below). I also added a new GUI button to use the weighted init method, so I could tweak the values to my liking. I intend to generate at run time. public void InitializeWithWeight()
{
// Get the world engine and tell it we are preparing to generate
World world = World.instance;
World.status = HoneyFramework.World.Status.Preparation;
// Refresh terrain definitions
TerrainDefinition.ReloadDefinitions();
// Clear out the old hex data
world.hexes = new Dictionary<Vector3i, Hex>();
// Get the hexes we are going to populate
List<Vector3i> rangeHexes = HexNeighbors.GetRange(new Vector3i(), world.hexRadius);
int terrainCount = TerrainDefinition.definitions.Count;
if (terrainCount < 1)
{
Debug.LogError("No terrain definitions to use!");
return;
}
// calculate the total weight of rarity
int totalWeight = MHTerrain.list.Sum(t => t.mode == MHTerrain.Mode.normal ? t.weight : 0);
int weight;
// Add the hex data
Hex hex;
MHTerrain td;
foreach (Vector3i v in rangeHexes)
{
hex = new Hex();
hex.orderPosition = UnityEngine.Random.Range(0f, 1f);
hex.rotationAngle = UnityEngine.Random.Range(0f, 360f);
// Just grab the first non-sea terrain type (but overwrite with rarity)
td = MHTerrain.list.First(t => t.isSeaType == false);
// value to look for
weight = Random.Range(0, totalWeight);
// updated weight value as we iterate through potential matches
int newWeight = 0;
// find the terrain whose range fits within that amount
foreach (MHTerrain terrain in MHTerrain.list)
{
if (terrain.mode != MHTerrain.Mode.normal) continue;
newWeight += terrain.weight;
if (weight <= newWeight)
{
td = terrain;
break;
}
}
hex.terrainType = TerrainDefinition.definitions.First(t => t.source.OID == td.OID);
hex.position = v;
HexWorld.instance.ReadyToPolishHex(hex);
world.hexes.Add(v, hex);
}
RiverFactory.CreateRivers(this, hexRadius);
// Force terrain redraw
for (int x = -world.chunkRadius; x <= world.chunkRadius; x++)
for (int y = -world.chunkRadius; y <= world.chunkRadius; y++)
{
world.PrepareChunkData(new Vector2i(x, y));
}
// Update the status to show the engine is generating the terrain
HexWorld.status = HoneyFramework.HexWorld.Status.TerrainGeneration;
}Haven't looked into getting the rivers to run into the lakes yet. Thanks guys!  |

How did you manage to disable the borders of the hex. I cant find that line.
