Commander

What's New:

User Changes:

This update introduces new JSON commands to interact with persistent data.

commander:store_nbt_data which allows you to store a simple string or number value, and commander:store_expression_data just like store_nbt_data, but with expressions.

{
  "type": "commander:store_nbt_data", //command type
  "target": "level", //the target we want to attach data to.
  "selector": "origin", //Selector for position and entity targets.
  "key": "cmd_my_cool_data", //The data key for later reference.
  "element": "Hello World!" //Our string or number value. This is a nbt element, so true and false are not supported.
}

store_expression_data is identical, but element is renamed to expression and only accepts expressions.

The target can be one of the following:

• level current level. Any selector.
• chunk selected chunk. Position selector.
• entity selected entity. Entity selector.
• block_entity selected block entity. Position selector.

Later on this data can be used in expressions like so:

level.storage.my_cool_data * 0.7 or this_entity.storage.even_cooler_data == 'freak''.

Along with the JSON command this update introduces a the cmd:data brigadier command. This command allows you to read and write data just like the JSON command.

The syntax goes like this:

cmd:data -> operation (read/write) -> target -> selector (@s/~ ~ ~) -> key (-> data (for write))

Other Changes:

• Moved mappings cache to ~/.commander.
• Mapping are now saved as compressed TSRG2.

Dev Changes:
