Spawn condition

Spawn conditions are used to determine which variant to spawn. Each variant contains a list of conditions with attached priorities. The selection of a variant happens in 3 steps:

1. Each condition is evaluated. The matching condition with the highest priority determines the priority of the variant. If no condition matches the variant is discarded.
2. Of all remaining variants, all except those with the highest priority are discarded.
3. Of the remaining variants, a random variant is chosen.

Spawn conditions are specified using the following format:

• Template:Nbt: List of spawn conditions with priority
  • Template:Nbt: A single spawn condition
    • Template:Nbt: The priority of the variant if this spawn condition matches
    • Template:Nbt: Condition to match. Always matches if omitted
