代码
以下是Minecraft的OceanRuinPiece.java的handleDataMarker的代码
public void handleDataMarker(String function, BlockPos blockPos, IWorld iWorld, Random random, MutableBoundingBox mutableBoundingBox) {
if ("chest".equals(function)) {
iWorld.setBlockState(blockPos, (BlockState)Blocks.CHEST.getDefaultState().with(ChestBlock.WATERLOGGED, iWorld.getFluidState(blockPos).isTagged(FluidTags.WATER)), 2);
TileEntity tileEntity = iWorld.getTileEntity(blockPos);
if (tileEntity instanceof ChestTileEntity) {
((ChestTileEntity)tileEntity).setLootTable(this.isLarge ? LootTables.CHESTS_UNDERWATER_RUIN_BIG : LootTables.CHESTS_UNDERWATER_RUIN_SMALL, random.nextLong());
}
} else if ("drowned".equals(function)) {
DrownedEntity drownedEntity = (DrownedEntity)EntityType.DROWNED.create(iWorld.getWorld());
drownedEntity.enablePersistence();
drownedEntity.moveToBlockPosAndAngles(blockPos, 0.0F, 0.0F);
drownedEntity.onInitialSpawn(iWorld, iWorld.getDifficultyForLocation(blockPos), SpawnReason.STRUCTURE, (ILivingEntityData)null, (CompoundNBT)null);
iWorld.addEntity(drownedEntity);
if (blockPos.getY() > iWorld.getSeaLevel()) {
iWorld.setBlockState(blockPos, Blocks.AIR.getDefaultState(), 2);
} else {
iWorld.setBlockState(blockPos, Blocks.WATER.getDefaultState(), 2);
}
}
}
问题
handleDataMarker的参数String function传入的是什么类型的函数，是在什么时候传入的，或者说具体传了什么东西？
如果我想在通过读取预定义的nbt结构文件，生成结构的时候，例如生成箱子的时候，在里面动态地放置一些物品，应该如何操作？
