resource (possibly infinite) with multiple possible results

[slay_mithos]

Hello,

I am trying to make a resource, based on infinite oil spawn, that can be mined by normal miners, and would each time output one result out off a list of 5.

Here is the my definition, using Dytech gems as results (but could be anything, really).

code

Code: Select all

data:extend(
{
	{
    type = "resource",
    name = "gems-test",
    icon = "__base__/graphics/icons/crude-oil.png",
    flags = {"placeable-neutral"},
    --category = "basic-fluid",
    order="a-b-a",
    infinite = true,
    minimum = 1,
    normal = 100,
    minable =
    {
      hardness = 0.5,
      mining_time = 10,
      results =
      {
        {
          name = "ruby-ore",
          amount_min = 0,
          amount_max = 1,
          probability =0.1
        },
        {
          name = "sapphire-ore",
          amount_min = 0,
          amount_max = 1,
          probability = 0.1
        },
        {
          name = "emerald-ore",
          amount_min = 0,
          amount_max = 1,
          probability = 0.1
        },
        {
          name = "topaz-ore",
          amount_min = 0,
          amount_max = 1,
          probability = 0.1
        },
        {
          name = "diamond-ore",
          amount_min = 0,
          amount_max = 1,
          probability = 0.1
        }
      }
    },
    collision_box = {{ -1.4, -1.4}, {1.4, 1.4}},
    selection_box = {{ -0.5, -0.5}, {0.5, 0.5}},
    autoplace =
    {
      control = "gems",
      sharpness = 1,
      max_probability = 0.04,
      richness_multiplier = 1,
      richness_base = 1,
      size_control_multiplier = 0.06,
      peaks =
      {
        {
          influence = 0.1
        },
        {
          influence = 0.105,
          starting_area_weight_optimal = 1,
          starting_area_weight_range = 0,
          starting_area_weight_max_range = 2,
        },
        {
          influence = 0.67,
          noise_layer = "gems",
          noise_octaves_difference = -2.7,
          noise_persistence = 0.3
        }
      }
    },
    stage_counts = {0},
    stages =
    {
      filename = "__base__/graphics/entity/crude-oil/crude-oil.png",
      priority = "extra-high",
      frame_width = 75,
      frame_height = 61,
      frame_count = 4,
      direction_count = 1
    },
    map_color = {r=0, g=1, b=0},
    map_grid = false
  },
})

My problem is that it will pick one output, output tons of it in front of my burner mining drill, on a belt, but never inside a chest.

What I wanted to do is that each cycle would output one and only one piece of only one of the 5 types.

It might be me not thinking it right, misusing the 'infinite' spawns, or even misusing the multiple results, so I wanted to ask for advices from people knowing their stuff better than I do.

this is multiple results bug, so devs must pay attention to this.

[AlexPhoenix]

i'll post it to bug section.

[Dysoch]

also when its working correctly, you have a bug

all the chances to get the ores combined are 0.5 (they need to be 1!)
so changing all to 0.2 would fix it

[slay_mithos]

Ah, no, this was a test to check if it fixed the problem.

In fact, the probability does not have to be 1 in total, because the engine will call the RAND function for each entry separately, meaning that the 'probability' is not a randomization between the results.

i think

Code: Select all

        {
          name = "ruby-ore",
          amount_min = 1,
          amount_max = 1,
          probability =0.1
        }

can work(or use 1-2)

[slay_mithos]

It's still not as I would, because making the yield 100% and the total probabilities to 1 doesn't always give me one result, and I am pretty sure I also got a few times with 2 at once.

Either way, it's still good enough to "solve" the gems generation problem that DyTech has been suffering from, and that became game crippling with 0.9.2.

Many thanks Alex.
