The condition placement modifier tests a placement condition to see if the placed feature should be placed at its current position.

{
  "type": "lithostitched:condition",
  "condition": {
    "type": "lithostitched:sample_density",
    "density_function": "minecraft:overworld/ridges",
    "min_inclusive": -0.3,
    "max_inclusive": 0.3
  }
}

The noise_slope placement modifier is a more configurable version of the noise_based_count placement modifier. The number of placements is defined as ceil(noise output * slope) + offset.

{
  "type": "lithostitched:noise_slope",
  "noise": "minecraft:surface",
  "slope": 5,
  "offset": 2,
  "xz_scale": 0.5,
  "y_scale": 0
}

• noise: The noise key, referencing a file in the worldgen/noise folder.
• slope: The number to multiply the noise by.
• offset: The number to offset the sloped number by.
• xz_scale: The scale of the noise on the x and z axes.
• y_scale: The scale of the noise on the y axis.

The offset placement modifier is a more configurable version of vanilla's random_offset placement modifier.

{
  "type": "lithostitched:offset",
  "x_offset": 0,
  "y_offset": {
    "type": "minecraft:uniform",
    "min_inclusive": 2,
    "max_inclusive": 4
  },
  "z_offset": 2
}

All offset fields are optional int providers and will default to 0.
