/listen Command

I have an idea that will permit event handling in Minecraft. My idea is to add a command called listen. It syntax would be as follows:

/listen <target: target> <event: string> <data: int, string, x y z...> <command: command>
OR
/listen <position: x y z> <event: string> <data: dict> <command: command>

So, the listen command creates an event listener that focuses on an entity (syntax 1) or block (syntax 2) and runs a command when the entity does something or has something done to it. The event argument is the main idea as to what happens, and the data are a dictionary with more info for the event. The dictionary would be written in the format: info: value. Here is a table of different events and their required data for entities:

Event Description Arguments

Used An entity item: string

used an item

Destroyed an entity item: string

destroyed/

attacked

with an item

Jumped an entity jumped none

Sneaked a player sneaked none

landed an entity landed block: string

on a block

Note that writing 'any' means that the value could be anything. There are also different events for blocks, but some could be of the same name: like 'destroy' for blocks is different as only that block triggers the event.

I hope you like the idea.

In Java Edition, this is possible with advancements. So for you Java Edition folks, the equivalent is to make an advancement for that purpose, with an event like minecraft:placed_block or a similar name. Then you can detect it by connecting it to a function that runs when you place that block.
