Direct Known Subclasses:

SchematicBlockBase, SchematicEntity

public class Schematic
extends java.lang.Object

This class allow to specify specific behavior for blocks stored in blueprints: - what items needs to be used to create that block - how the block has to be built on the world - how to rotate the block - what extra data to store / load in the blueprint Default implementations of this can be seen in the package buildcraft.api.schematics. The class SchematicUtils provide some additional utilities. Blueprints perform "id translation" in case the block ids between a blueprint and the world installation are different. Mapping is done through the builder context. At blueprint load time, BuildCraft will check that each block id of the blueprint corresponds to the block id in the installation. If not, it will perform a search through the block list, and upon matching signature, it will translate all blocks ids of the blueprint to the installation ones. If no such block id is found, BuildCraft will assume that the block is not installed and will not load the blueprint.

Method Detail

isAlreadyBuilt

public boolean isAlreadyBuilt(IBuilderContext context,
                     int x,
                     int y,
                     int z)

Return true if the block on the world correspond to the block stored in the blueprint at the location given by the slot. By default, this subprogram is permissive and doesn't take into account metadata.

getRequirements

public final java.util.LinkedList<net.minecraft.item.ItemStack> getRequirements(IBuilderContext context)

addRequirements

public void addRequirements(IBuilderContext context,
                   java.util.LinkedList<net.minecraft.item.ItemStack> requirements)

Returns the requirements needed to build this block. When the requirements are met, they will be removed all at once from the builder, before calling buildBlock.

useItem

public net.minecraft.item.ItemStack useItem(IBuilderContext context,
                                   net.minecraft.item.ItemStack req,
                                   net.minecraft.item.ItemStack stack)

This is called each time an item matches a reqquirement, that is: (req id == stack id) for damageable items (req id == stack id && req dmg == stack dmg) for other items by default, it will increase damage of damageable items by the amount of damage of the requirement, and remove the intended amount of non damageable item. Client may override this behavior for default items. Note that this subprogram may be called twice with the same parameters, once with a copy of requirements and stack to check if the entire requirements can be fullfilled, and once with the real inventory. Implementer is responsible for updating req (with the remaining requirements if any) and stack (after usage) returns: what was used (similer to req, but created from stack, so that any NBT based differences are drawn from the correct source)

rotateLeft

public void rotateLeft(IBuilderContext context)

Perform a 90 degree rotation to the slot.

transformToBlueprint

public void transformToBlueprint(MappingRegistry registry,
                        Translation transform)

Performs a transformations from world to blueprints. In particular, it should: - use the registry to map ids from world to blueprints - apply translations to all positions in the schematic to center in the blueprint referencial

transformToWorld

public void transformToWorld(MappingRegistry registry,
                    Translation transform)

Performs a transformations from blueprints to worlds. In particular, it should: - use the registry to map ids from blueprints to world - apply translations to all positions in the schematic to center in the builder referencial

writeToWorld

public void writeToWorld(IBuilderContext context,
                int x,
                int y,
                int z,
                java.util.LinkedList<net.minecraft.item.ItemStack> stacks)

Places the block in the world, at the location specified in the slot, using the stack in parameters

readFromWorld

public void readFromWorld(IBuilderContext context,
                 int x,
                 int y,
                 int z)

Initializes a slot from the blueprint according to an objet placed on {x, y, z} on the world. This typically means adding entries in slot.cpt. Note that "id" and "meta" will be set automatically, corresponding to the block id and meta. By default, if the block is a BlockContainer, tile information will be to save / load the block.

postProcessing

public void postProcessing(IBuilderContext context,
                  int x,
                  int y,
                  int z)

Called on a block when the blueprint has finished to place all the blocks. This may be useful to adjust variable depending on surrounding blocks that may not be there already at initial building.
