Blockdaten aus Schaltplan in Bukkit setzen?
Ich versuche a zu laden und einzufügen.schematic Datei (ohne die MCEdit-API einzuhängen) in Bukkit. Unten ist die Funktion / Methode, die ich benutze, um den Schaltplan einzufügen. Beim Einfügen bekomme ich immer eineNullPointerException beim Einfügen. Wenn ich mich anmelde, welche Gegenstände platziert wurden, sehe ich Grasblöcke, Steine, aber nicht meine Truhen, irgendetwas in den Truhen oder Leuchtfeuer (vielleicht sogar noch mehr Blöcke).
Der Fehler tritt in dieser Zeile auf:block.setData(blockData[index], true);
Ich denke, dies hat etwas mit den Metadaten zu tun, aber wie würde ich diese Informationen aus der Schaltplandatei erhalten und sie auf jeden der Blöcke anwenden?
Frage:How can i paste items with metaData like (Chest with contents, torches, beacons, etc.?
@SuppressWarnings("deprecation")
public void pasteSchematic(World world, Location loc, Schematic schematic)
{
byte[] blocks = schematic.getBlocks();
byte[] blockData = schematic.getData();
short length = schematic.getLenght();
short width = schematic.getWidth();
short height = schematic.getHeight();
for (int x = 0; x < width; ++x) {
for (int y = 0; y < height; ++y) {
for (int z = 0; z < length; ++z) {
int index = y * width * length + z * width + x;
Block block = new Location(world, x + loc.getX(), y + loc.getY(), z + loc.getZ()).getBlock();
block.setTypeId(blocks[index], true);
block.setData(blockData[index], true);
if(block.getType() == Material.BEACON || block instanceof Beacon) {
// Add location up one block
getLogger().info("Block is a Beacon!");
spawnLocations.add(block.getLocation().add(new Location(block.getWorld(),0,1,0)));
} else {
getLogger().info("Block is a " + block.getType().toString() + " block!");
}
}
}
}
}
Und um die schematische Datei zu laden:
public Schematic loadSchematic(File file) throws IOException
{
FileInputStream stream = new FileInputStream(file);
@SuppressWarnings("resource")
NBTInputStream nbtStream = new NBTInputStream(stream);
CompoundTag schematicTag = (CompoundTag) nbtStream.readTag();
if (!schematicTag.getName().equals("Schematic")) {
throw new IllegalArgumentException("Tag \"Schematic\" does not exist or is not first");
}
Map<String, Tag> schematic = schematicTag.getValue();
if (!schematic.containsKey("Blocks")) {
throw new IllegalArgumentException("Schematic file is missing a \"Blocks\" tag");
}
short width = getChildTag(schematic, "Width", ShortTag.class).getValue();
short length = getChildTag(schematic, "Length", ShortTag.class).getValue();
short height = getChildTag(schematic, "Height", ShortTag.class).getValue();
String materials = getChildTag(schematic, "Materials", StringTag.class).getValue();
if (!materials.equals("Alpha")) {
throw new IllegalArgumentException("Schematic file is not an Alpha schematic");
}
byte[] blocks = getChildTag(schematic, "Blocks", ByteArrayTag.class).getValue();
byte[] blockData = getChildTag(schematic, "Data", ByteArrayTag.class).getValue();
return new Schematic(blocks, blockData, width, length, height);
}
/**

*
* @param items The parent tag map
* @param key The name of the tag to get
* @param expected The expected type of the tag
* @return child tag casted to the expected type
* @throws DataException if the tag does not exist or the tag is not of the

*/
private static <T extends Tag> T getChildTag(Map<String, Tag> items, String key, Class<T> expected) throws IllegalArgumentException
{
if (!items.containsKey(key)) {
throw new IllegalArgumentException("Schematic file is missing a \"" + key + "\" tag");
}
Tag tag = items.get(key);
if (!expected.isInstance(tag)) {
throw new IllegalArgumentException(key + " tag is not of tag type " + expected.getName());
}
return expected.cast(tag);
}
AKTUALISIEREN Nach weiteren Tests tritt der Fehler immer noch auf, auch wenn ich die Truhe und das Leuchtfeuer (nur Gras und Stein) entferne. Ich rufe dieses Ereignis anonSignChange wenn das hilft.
Unten ist der Fehler in der Konsole:
