xNature | Minecraft plugin

This plugin modifies the way different blocks work in minecraft. Using the ItemsAdder plugin (I can provide a version for testing), a special block is assigned to different blocks. This block will be written (either manually or via this plugin) to blockstates. Subsequently, when I call the item from the ItemsAdder, it will be this leaves, for example. Furthermore, this plugin will automatically convert already existing blocks to the default value (default value = Vanilla). This transformation would also take place in created worlds, preferably asynchronously. At the same time, vanilla functionality would be preserved for the new blocks. So, for example, sheet decay, etc. It is important that the plugin cooperates with plugins - Oraxen, ItemsAdder, WorldEdit. Furthermore, so that the plugin does not ignore flags from WorldEdit, for example (decay flag)
