解决Minecraft 1.17.1→1.18.2移植中getStructureAt参数不匹配问题

问题核心是1.18.2版本中StructureFeatureManager.getStructureAt()的方法签名发生了变更：原1.17.1的三参数重载（getStructureAt(pos, false, structure)）被移除，仅保留接收BlockPos和布尔值的两参数版本，直接传入三个参数会触发编译错误。

修改方案

调整代码逻辑，先通过两参数方法获取结构实例，再判断该实例是否属于目标结构类型，具体修改如下：

private boolean isTower(ServerLevel level, BlockPos pos) {
  LOGGER.info("Checking for tower...");
  StructureFeature<?> structure;
  StructureStart<?> structurePos;

  for (String s : Arrays.asList("tower", "ice_tower", "jungle_tower", "derelict_tower", "derelict_grass_tower", "ocean_tower", "ocean_warm_tower")) {
    structure = ForgeRegistries.STRUCTURE_FEATURES.getValue(ResourceLocation.tryParse(TOWERS_MODID + ":" + s));
    if (structure == null) {
      continue;
    }
    // 调用两参数版本的getStructureAt
    structurePos = level.structureFeatureManager().getStructureAt(pos, false);
    // 先判空，再检查结构有效性与匹配性
    if (structurePos != null && structurePos.isValid() && structurePos.getStructureFeature() == structure) {
      // Manhattan distance without Y coord
      float f = (float) Math.abs(pos.getX() - structurePos.getLocatePos().getX());
      float f1 = (float) Math.abs(pos.getZ() - structurePos.getLocatePos().getZ());
      if (f + f1 <= 30) {
        return true;
      }
    }
  }
  // 补充方法默认返回值，覆盖所有代码路径
  return false;
}
