Vwoops

The mod expands upon the minecraft:enderman_holdable block tag and provides granular control of blocks in this tag without modifying the tag itself.
Blocks can be added to a list of "holdable" blocks. Adding a block to this list will permit Endermen to pick up the block. Removing a block from this list will stop Endermen from picking up the block.

Usage

Singleplayer
Since block tags can be specified per world through data packs, single-player worlds are configured on a per-world basis. Use the /vwoops command to open the config screen. The config file can be found in the save directory as vwoops.json

Server

Use the /vwoops command with any of the following sub-commands. The config file can be found in the world directory as vwoops.json add Adds the block with the specified ID to the list of "holdable" blocks. e.g., /vwoops add minecraft:dandelion add * Adds all blocks to the list of "holdable" blocks. e.g., /vwoops add * remove Removes the block with the specified ID from the list of "holdable" blocks. e.g., /vwoops remove minecraft:dandelion remove * Removes all blocks from the list of "holdable" blocks. e.g., /vwoops remove *
