  • Method Details

    • self

      private Block self()

    • getFriction

      default float getFriction(BlockState state, LevelReader level, BlockPos pos, @Nullable @Nullable Entity entity)
      Gets the slipperiness at the given location at the given state. Normally between 0 and 1.

      Note that entities may reduce slipperiness by a certain factor of their own; for LivingEntity, this is .91. ItemEntity uses .98, and FishingHook uses .92.

      Parameters:
      state - state of the block
      level - the level
      pos - the position in the level
      entity - the entity in question
      Returns:
      the factor by which the entity's motion should be multiplied

    • getLightEmission

      default int getLightEmission(BlockState state, BlockGetter level, BlockPos pos)
      Get a light value for this block, taking into account the given state and coordinates, normal ranges are between 0 and 15
      Parameters:
      state - The state of this block
      level - The level this block is in
      pos - The position of this block in the level, will be BlockPos.ZERO when the chunk being loaded or generated calls this to check whether it contains any light sources
      Returns:
      The light value
      Implementation Note:
      • If the given state of this block may emit light but requires position context to determine the light value, then it must return a non-zero light value if (pos == BlockPos.ZERO) in order for the chunk calling this to be considered as containing light sources.
      • The given BlockGetter may be a chunk. Block, fluid or block entity accesses outside of its bounds will cause issues such as wrapping coordinates returning values from the opposing chunk edge
      • This method may be called on a worker thread and must therefore use IForgeBlockGetter.getExistingBlockEntity(BlockPos) to retrieve the BlockEntity at the given position

      explosion - The explosion instance affecting the block

    • collisionExtendsVertically

      default boolean collisionExtendsVertically(BlockState state, BlockGetter level, BlockPos pos, Entity collidingEntity)
      Determines if this block's collision box should be treated as though it can extend above its block space. Use this to replicate fence and wall behavior.

    • shouldDisplayFluidOverlay

      default boolean shouldDisplayFluidOverlay(BlockState state, BlockAndTintGetter level, BlockPos pos, FluidState fluidState)
      Called to determine whether this block should use the fluid overlay texture or flowing texture when it is placed under the fluid.

    • getToolModifiedState

      @Nullable default @Nullable BlockState getToolModifiedState(BlockState state, UseOnContext context, ToolAction toolAction, boolean simulate)
      Returns the state that this block should transform into when right-clicked by a tool. For example: Used to determine if an axe can strip, a shovel can path, or a hoe can till. Returns null if nothing should happen.
      Parameters:
      state - The current state
      context - The use on context that the action was performed in
      toolAction - The action being performed by the tool
      simulate - If true, no actions that modify the world in any way should be performed. If false, the world may be modified.
      Returns:

    • isScaffolding

      default boolean isScaffolding(BlockState state, LevelReader level, BlockPos pos, LivingEntity entity)
      Checks if a player or entity handles movement on this block like scaffolding.
      Parameters:
      state - The current state
      level - The current level
      pos - The block position in level
      entity - The entity on the scaffolding
      Returns:
      True if the block should act like scaffolding

    • canConnectRedstone

      default boolean canConnectRedstone(BlockState state, BlockGetter level, BlockPos pos, @Nullable @Nullable Direction direction)
      Whether redstone dust should visually connect to this block on a given side

      The default implementation is identical to RedStoneWireBlock#shouldConnectTo(BlockState, Direction)

      RedStoneWireBlock updates its visual connection when BlockBehaviour.BlockStateBase.updateShape(Direction, BlockState, LevelAccessor, BlockPos, BlockPos) is called, this callback is used during the evaluation of its new shape.

      Parameters:
      state - The current state
      level - The level
      pos - The block position in level
      direction - The coming direction of the redstone dust connection (with respect to the block at pos)
      Returns:
      True if redstone dust should visually connect on the side passed

      If the return value is evaluated based on level and pos (e.g. from BlockEntity), then the implementation of this block should notify its neighbors to update their shapes when necessary. Consider using BlockBehaviour.BlockStateBase.updateNeighbourShapes(LevelAccessor, BlockPos, int, int) or BlockBehaviour.BlockStateBase.updateShape(Direction, BlockState, LevelAccessor, BlockPos, BlockPos).

      Example:

      1. yourBlockState.updateNeighbourShapes(level, yourBlockPos, UPDATE_ALL);

      2. neighborState.updateShape(fromDirection, stateOfYourBlock, level, neighborBlockPos, yourBlockPos), where fromDirection is defined from the neighbor block's point of view.

    • hidesNeighborFace

      default boolean hidesNeighborFace(BlockGetter level, BlockPos pos, BlockState state, BlockState neighborState, Direction dir)
      Whether this block hides the neighbors face pointed towards by the given direction.

      This method should only be used for blocks you don't control, for your own blocks override BlockBehaviour.skipRendering(BlockState, BlockState, Direction) on the respective block instead

      WARNING: This method is likely to be called from a worker thread! If you want to retrieve a BlockEntity from the given level, make sure to use IForgeBlockGetter.getExistingBlockEntity(BlockPos) to not accidentally create a new or delete an old BlockEntity off of the main thread as this would cause a write operation to the given BlockGetter and cause a CME in the process. Any other direct or indirect write operation to the BlockGetter will have the same outcome.

      Parameters:
      level - The world
      pos - The blocks position in the world
      state - The blocks BlockState
      neighborState - The neighboring blocks BlockState
      dir - The direction towards the neighboring block

    • supportsExternalFaceHiding

      default boolean supportsExternalFaceHiding(BlockState state)
      Whether this block allows a neighboring block to hide the face of this block it touches. If this returns true, IForgeBlockState.hidesNeighborFace(BlockGetter, BlockPos, BlockState, Direction) will be called on the neighboring block.

    • onBlockStateChange

      default void onBlockStateChange(LevelReader level, BlockPos pos, BlockState oldState, BlockState newState)
      Called after the BlockState at the given BlockPos was changed and neighbors were updated. This method is called on the server and client side. Modifying the level is disallowed in this method. Useful for calculating additional data based on the new state and the neighbor's reactions to the state change.
      Parameters:
      level - The level the state was modified in
      pos - The blocks position in the level
      oldState - The previous state of the block at the given position, may be a different block than this one
      newState - The new state of the block at the given position

    • canBeHydrated

      default boolean canBeHydrated(BlockState state, BlockGetter getter, BlockPos pos, FluidState fluid, BlockPos fluidPos)
      Returns whether the block can be hydrated by a fluid.

      Hydration is an arbitrary word which depends on the block.

      • A farmland has moisture
      • A sponge can soak up the liquid
      • A coral can live
      Parameters:
      state - the state of the block being hydrated
      getter - the getter which can get the block
      pos - the position of the block being hydrated
      fluid - the state of the fluid
      fluidPos - the position of the fluid
      Returns:
      true if the block can be hydrated, false otherwise

    • getMapColor

      default MapColor getMapColor(BlockState state, BlockGetter level, BlockPos pos, MapColor defaultColor)
      Returns the MapColor shown on the map.
      Parameters:
      state - The state of this block
      level - The level this block is in
      pos - The blocks position in the level
      defaultColor - The MapColor configured for the given BlockState in the BlockBehaviour.Properties

    • getAppearance

      default BlockState getAppearance(BlockState state, BlockAndTintGetter level, BlockPos pos, Direction side, @Nullable @Nullable BlockState queryState, @Nullable @Nullable BlockPos queryPos)
      Returns the BlockState that this block reports to look like on the given side, for querying by other mods. Note: Overriding this does not change how this block renders. That must still be handled in the block's model.

      Common implementors would be covers and facades, or any other mimic blocks that proxy another block's model. Common consumers would be models with connected textures that wish to seamlessly connect to mimic blocks.

      Note that this method may be called on the server, or on any of the client's meshing threads.
      As such, if you need any data from your BlockEntity, you should put it in ModelData to guarantee safe concurrent access to it on the client.
      Calling IForgeBlockGetter.getModelDataManager() will return null if in a server context, where it is safe to query your BlockEntity directly. Otherwise, ModelDataManager.getAt(BlockPos) will return the ModelData for the queried block, or null if none is present.

      Parameters:
      state - The state of this block
      level - The level this block is in
      pos - The block's position in the level
      side - The side of the block that is being queried
      queryState - The state of the block that is querying the appearance, or null if not applicable
      queryPos - The position of the block that is querying the appearance, or null if not applicable
      Returns:
      The appearance of this block on the given side. By default, the current state

    • getPistonPushReaction

      @Nullable default @Nullable PushReaction getPistonPushReaction(BlockState state)
      Returns the reaction of the block when pushed or pulled by a piston. This method should be not called directly, instead via BlockBehaviour.BlockStateBase.getPistonPushReaction().
      • NORMAL: is pushable and pullable by sticky pistons
      • DESTROY: is being destroyed on pushing and pulling
      • BLOCK: is not being able to be moved
      • IGNORE: only usable by entities
      • PUSH_ONLY: can only be pushed, blocks on trying to be pulled
      • null: use the PistonPushReaction from the BlockBehaviour.Properties passed into the Block Constructor
      Parameters:
      state - The state of this block
      Returns:
      the PushReaction of this state or null if the one passed into the block properties should be used
