# How to use HEART\_OF\_THE\_SEA? The `HEART_OF_THE_SEA` listener is very useful for those who know how to use it. `HEART_OF_THE_SEA` listener is used to add a specific configuration to `ALL` blocks that are broken inside that region. For example, if you have a cave and you have blocks like: * Dirt * Stone * Diorite * Andesite * Gravel * Coal Ore And want to disable every block from breaking, but want to only let players mine Coal Ore and Stone, then you can use `HEART_OF_THE_SEA` listener to make your life easier. By setting the `duration` of `HEART_OF_THE_SEA` to `-1` you are disabling breaking that block. Which means that `ALL` blocks are now disabled and players can't break any of them. Now since we disabled `ALL` blocks, we can enable only those we want players to be able to break like Coal Ore and Stone. Now configure Coal Ore and Stone however you want and now players should be able to break them! Here is an example configuration for this system: ```yaml block_listeners: '0': block_type: HEART_OF_THE_SEA duration: -1 '1': block_type: COAL_ORE duration: 15 # 15 seconds default_drops: true # Give default drops '2': block_type: STONE duration: 5 # 5 seconds default_drops: true # Give default drops ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
