Record Class SpawnData.MobCost

java.lang.Object
java.lang.Record
cz.jeme.bestium.api.inject.biome.SpawnData.MobCost
Record Components:
charge - how much charge this mob contributes to the spawn area
energyBudget - maximum total charge a spawn location can tolerate before blocking the spawn
Enclosing class:
SpawnData
public static record SpawnData.MobCost(double charge, double energyBudget) extends Record
Represents additional spawn constraints introduced in Minecraft 1.16 ("The Nether Update"). Mob cost prevents entities from spawning too close to each other by assigning a charge and an energy budget.

Each mob contributes its charge to nearby blocks (scaled by distance). When a new mob tries to spawn, the cumulative charge of surrounding entities is calculated. If the total exceeds the energyBudget, the mob is not allowed to spawn. This creates natural spacing between mobs.

For example, in vanilla Minecraft, endermen in warped forests use mob costs to spawn less densely.
