解决方法:
List<Location> getLocationsAroundPlayer(Player player, double radius) {
    World world = player.getWorld();
    Location playerLocation = player.getLocation();
    double x = playerLocation.getX();
    double y = playerLocation.getY();
    double z = playerLocation.getZ();

    List<Location> locations = new ArrayList<Location>();
    for (double nowX = x - radius; nowX <= x + radius; nowX++) {
        for (double nowY = y - radius; nowY <= y + radius; nowY++) {
            for (double nowZ = z - radius; nowZ <= z + radius; nowZ++) {
                Location location = new Location(world, nowX, nowY, nowZ);
                double distance = playerLocation.distance(location);
                if (distance <= radius) {
                    locations.add(location);
                }
            }
        }
    }
    return locations;
}

“玩家周围的所有坐标”包含了无限个坐标，比如 (0, 0, 0.1) 、(0, 0, 0.2) 等等，没有办法“得到”
