Dimension Entity Blocker

Custom entities can be prevented from entering custom worlds through simple configuration.
For example, adding falling block can prevent sand and dragon eggs from entering end from other worlds, thus effectively preventing the use of end portal to duplicate sand and dragon eggs.
Of course, you can add minecraft:player to prevent players from entering a particular world.

可以通过简单的配置，阻止自定义实体进入自定义世界
比如给末地添加下坠的方块，可以防止沙子、龙蛋从其他世界进入末地，从而有效避免利用末地传送门刷沙子和龙蛋
当然你可以添加 minecraft:player 来阻止玩家进入某世界
