As I already read in the title, I'm currently building in the Bedrock edition of Minecraft Bedwars. Now to my question it is somehow possible to reset the map. So delete blocks. To rebuild beds etc.
This happens on the server side with plugins.
Theoretically it would probably go with command blocks also if you copied the area somewhere and re-insert after the round again to the desired place.
You would have to save the map with Structure blocks and reload the saved one. Have a look at a tutorial.
Do you have a YouTube video?
