    • harvest

      public void harvest(net.minecraft.world.level.Level world, net.minecraft.world.level.BlockGetter chunkCache, net.minecraft.core.BlockPos pos, net.minecraft.world.level.block.state.BlockState state, IDrone drone)
      Should actually harvest the block. Usually this is just a matter of breaking the block, but you can override this for custom behavior.
      Parameters:
      world - the world
      chunkCache - Use preferably methods from this cache as it's generally quicker than accessing via 'world'. The cache has access to the chunks that are accessed by the Drone current program, so as long as only the y pos is varied of the supplied pos, you are good. If not, use 'world'.
      pos - the block's position
      state - the blockstate at the position
      drone - the drone doing the harvesting

    • harvestAndReplant

      public boolean harvestAndReplant(net.minecraft.world.level.Level world, net.minecraft.world.level.BlockGetter chunkCache, net.minecraft.core.BlockPos pos, net.minecraft.world.level.block.state.BlockState state, IDrone drone)
      Should harvest the block (drop items), and replant the plant if applicable. For example, for crops it should reset the growth stage to 0.
      Parameters:
      world - the world
      chunkCache - Use preferably methods from this cache as it's generally quicker than accessing via 'world'. The cache has access to the chunks that are accessed by the Drone current program, so as long as only the y pos is varied of the supplied pos, you are good. If not, use 'world'.
      pos - the block's position
      state - the blockstate at the position
      drone - the drone doing the harvesting
      Returns:
      true if the replanting succeeded (and the hoe the Drone carries needs to be damaged). If nothing needed to be replanted return false.

    • canHarvest

      public abstract boolean canHarvest(net.minecraft.world.level.Level world, net.minecraft.world.level.BlockGetter chunkCache, net.minecraft.core.BlockPos pos, net.minecraft.world.level.block.state.BlockState state, IDrone drone)
      Determines if the currently checked block can be harvested.
      Parameters:
      world - the world
      chunkCache - Use preferably methods from this cache as it's generally quicker than accessing via 'world'. The cache has access to the chunks that are accessed by the Drone current program, so as long as only the y pos is varied of the supplied pos, you are good. If not, use 'world'.
      pos - the blockpos to be checked
      state - the blockstate
      drone - the drone
      Returns:
      true if the block can be harvested, false if not.

    • addFilterItems

      public List<net.minecraft.world.item.ItemStack> addFilterItems(net.minecraft.world.level.Level world, net.minecraft.world.level.BlockGetter chunkCache, net.minecraft.core.BlockPos pos, net.minecraft.world.level.block.state.BlockState state, IDrone drone)
      Should add the items the connected item filters in the Harvest puzzle piece in the Programmer can use to determine if a block should be harvested. Called after canHarvest(Level, BlockGetter, BlockPos, BlockState, IDrone), when that method returns true
      Parameters:
      world - the world
      chunkCache - Use preferably methods from this cache as it's generally quicker than accessing via 'world'. The cache has access to the chunks that are accessed by the Drone current program, so as long as only the y pos is varied of the supplied pos, you are good. If not, use 'world'.
      pos - the blockpos
      state - the blockstate
      drone - the drone
