🌴 Sapling Block

Sapling Block grows through stage levels on random ticks and eventually generates a full tree — either from a configured feature or from a worldgen structure. Growth only happens within a light range — between light_requirement (low, default 9) and max_light_requirement (high, default 15).

Bone meal advances one stage immediately (bypassing the light check). Whether the bone meal "succeeds" for particle effects depends on bone_meal_success_chance — the stage still advances regardless.

Example

blocks:
  default:palm_sapling:
    behavior:
      type: sapling_block
      feature: default:palm_tree                # the configured feature to generate when fully grown (required unless structure is set)
      # structure: default:palm_grove           # alternative: generate a registered structure instead
      light_requirement: 9                      # minimum light to grow (default 9)
      max_light_requirement: 15                 # maximum light to grow (default 15)
      grow_speed: 0.7                           # chance per random tick to advance a stage (default ~0.143)
      bone_meal_success_chance: 0.45            # chance bone meal triggers success particles (default 0.45)

feature vs structure

The two are mutually exclusive — set only one. feature takes a configured feature id (single feature placement, e.g. one tree). structure takes a structure id from the minecraft:structure registry (vanilla, datapack, or plugin-registered) and places that structure at the sapling's position — useful for groves or other builds assembled from structure templates. When structure is set, feature is ignored.

tip

The more stage values a sapling has, the longer its required growth time — each stage needs its own random tick.
