Nukkit服务器插件代码：获取指定坐标范围内所有坐标

以下是使用Java 8编写的符合要求的nukkit服务器插件代码：\n\njava\nimport cn.nukkit.level.Position;\nimport cn.nukkit.math.Vector3;\nimport java.util.ArrayList;\nimport java.util.List;\n\npublic class PluginExample extends PluginBase {\n\n public List<Position> getPositionsInRange(Position center, double distance) {\n List<Position> positions = new ArrayList<>();\n\n int minX = (int) (center.x - distance);\n int maxX = (int) (center.x + distance);\n int minY = (int) (center.y - distance);\n int maxY = (int) (center.y + distance);\n int minZ = (int) (center.z - distance);\n int maxZ = (int) (center.z + distance);\n\n for (int x = minX; x <= maxX; x++) {\n for (int y = minY; y <= maxY; y++) {\n for (int z = minZ; z <= maxZ; z++) {\n Position position = new Position(x, y, z, center.getLevel());\n if (center.distance(position) <= distance && position.y == center.y) {\n positions.add(position);\n }\n }\n }\n }\n\n return positions;\n }\n}\n\n\n请注意，上述代码假设你已经正确导入了nukkit库，并且创建了一个继承自PluginBase的插件类。getPositionsInRange方法接受一个Position对象和一个double类型的距离参数，并返回一个包含所有在距离Position中distance个距离的圈内的所有坐标的Position列表。
