Minecraft:Noise settings

• Spawn Target
  • The Template:Cd field has been updated to allow use of any density function, instead of just a subset of those defined within the Template:Cd field.
  • The suitability of a candidate spawn position is determined by evaluating, in some arbitrary n-dimensional space, the squared Euclidean distance to a set of target hypercubes.
  • For example, one axis might be temperature and the second erosion - and suitability determined by distance to the square between Template:Cd, Template:Cd and Template:Cd, Template:Cd. This would prefer any candidate spawn within those ranges equally, while penalizing candidate spawns very far out of that range.
  • Format: list of target hypercubes
    • Target format: map between Density Function ID and a range on that axis:
      • Range is specified as one of:
        • Float, an exact target value.
