# Resource Richness Distance Multiplier
2+
3+
You're almost done mining your starting iron ore patch. You need to expand.
4+
Lucky you, right next door there is an iron ore field huge enough to support your base for the rest of your life as well as that of your grandchildren.
5+
6+
This mod adds a bit of control on just how much richer the resource patches outside the starting area are.
7+
It does not alter the placement of ores from vanilla. As such, the map preview still works.
8+
9+
If you need more control, you should stick to good ol' [RSO](https://mods.factorio.com/mod/rso-mod).

{

initialize_patch_set = initialize_patch_set,
13+
resource_autoplace_settings = resource_autoplace_settings
14+
}
15+
```
16+
17+
`initialize_patch_set` defines spots that resources can spawn on.
18+
If omitted, it doesn't initially change anything it seems.
19+
20+
However, if the `probability_expression` is changesd, the probability applies to the entire map instead of just some
21+
blobs.
22+
23+

24+
25+
```
26+
local ret =
27+
{
28+
order = order,
29+
control = autoplace_control_name,
30+
probability_expression = probability_expression,
31+
richness_expression = probability_expression * 100 -- noise.random(800) + 400
32+
}
33+
```
34+
35+
`probability_expression` is a value between 0 and 1, indicating the chance that a particular tile will have a resource
36+
to begin with. If the chance is not actually 0 or 1, but something in between, resources patches will have empty tiles
37+
scatted across them.
38+
39+
`richness_expression` returns the exact amount of ore for a particular tile. Though I'm not sure how exactly this
40+
converts to yielding resources, e.g. oil patches.
41+
- tne(10000) -> 3%
42+
- tne(100000) -> 33%
43+
- tne(1000000) -> 333%
44+
45+
Note that this value must be at least 2. The tile won't spawn if it has a richness of less than that.
46+
Though it will still show up on the preview for map generation if the value is greater than 0.
47+
Floating point numbers are floored.
48+
49+
Both these values must be noise expressions, a regular number is not enough. You can use the `tne()` that is used in
50+
this file to convert numbers "To Noise Expression"s.
51+
52+
`noise.delimit_procedure(expression)` doesn't really do anything.
53+
It only causes outputs by `dump_expression(expression)` to be trimmed as not to clutter the output with a wall of math.
54+
55+

y = noise.var("y"),
66+
amplitude = tne(8)
67+
}
68+
}
69+
```
70+
71+
`source` is the base value.
72+
73+
`amplitude` is the maximum deviation from that base value.
74+
In the above example, the effective value is in the range 2..10
75+

starting_feasibility_richness * 2 -
93+
1 * distance / starting_resource_placement_radius +

basement_value = basement_value,
97+
maximum_spot_basement_radius = tne(128) -- does making this huge make a difference?
98+
}
99+
}
100+
```
101+
102+
`density_expression` seems to practically determine the max distance at which a resource can spawn.
103+
104+
# Variables
105+
106+
The returned expressions can contain variables that will be replaced somewhere in the C++ core I assume.
107+
These can be included by calling `noise.var("variableName")`.
108+
109+
Known variables:
110+
- `x`: X coordinate in tiles on the map
111+
- `y`: Y coordinate in tiles on the map
112+
- `distance`: Distance in tiles from the center of the map
113+
- `elevation`: Height of a specific tile
114+
- `map_seed`: Seed of the map
115+
- `regular-resource-patch-set-count`: ???
116+
- `starting-resource-patch-set-count`: ???
