Example 2 with ListTag

use of net.minecraft.nbt.ListTag in project MinecraftForge by MinecraftForge.

the class ItemStackHandler method deserializeNBT.

@Override
public void deserializeNBT(CompoundTag nbt) {
    setSize(nbt.contains("Size", Tag.TAG_INT) ? nbt.getInt("Size") : stacks.size());
    ListTag tagList = nbt.getList("Items", Tag.TAG_COMPOUND);

Example 3 with ListTag

use of net.minecraft.nbt.ListTag in project MinecraftForge by MinecraftForge.

the class ForgeChunkManager method writeForcedChunkOwners.

private static <T extends Comparable<? super T>> void writeForcedChunkOwners(Map<String, Long2ObjectMap<CompoundTag>> forcedEntries, Map<TicketOwner<T>, LongSet> forcedChunks, String listKey, int listType, BiConsumer<T, ListTag> ownerWriter) {
    for (Map.Entry<TicketOwner<T>, LongSet> entry : forcedChunks.entrySet()) {
        Long2ObjectMap<CompoundTag> modForced = forcedEntries.computeIfAbsent(entry.getKey().modId, modId -> new Long2ObjectOpenHashMap<>());
        for (long chunk : entry.getValue()) {
            CompoundTag modEntry = modForced.computeIfAbsent(chunk, chunkPos -> {
                CompoundTag baseEntry = new CompoundTag();
                baseEntry.putLong("Chunk", chunkPos);
                return baseEntry;
            });
            ListTag ownerList = modEntry.getList(listKey, listType);
            ownerWriter.accept(entry.getKey().owner, ownerList);
            // Note: As getList returns a new list in the case the data is of the wrong type,
            // we need to mimic was vanilla does in various places and put our list back in
            // the CompoundNBT regardless.
            modEntry.put(listKey, ownerList);
        }
    }
}
