Conditional Overlay

• Id: moderner_beta:conditional_overlay
• Inputs: parent
• Uses seed: depends on supplied predicates
• Added in: 3.0.0

The Conditional Overlay layer allows for biomes matching a predicate to be replaced with a certain layer target while biomes that don't match the predicate are replaced with a different target. This layer is analogous to an if-else statement or a ternary expression.

Properties

• predicate
  • Type: biome-predicate
  • Default: required
  • Description: The predicate to compare biomes to.
• onMatch
  • Type: layer-target
  • Default: required
  • Description: The target to apply if the predicate is satisfied.
• otherwise
  • Type: layer-target
  • Default: required
  • Description: The target to apply if the predicate is not satisfied.

Example

Conditional overlay layers are used for placing mushroom islands in oceans.
