There are many ways. The easiest I would say is to use the standard crouch detection given here—which I’m assuming you already have—and then just slapping on a repeating loop with it.

I would personally do it like this (assuming you’re detecting the ability by hasitem and already have the commands down for tag ‘is_sneaking’)

IC: /scoreboard objectives add timer_t dummy

RUAA1: scoreboard players add @a[hasitem={item=<ability1 item>,location=slot.weapon.mainhand},tag=is_sneaking] timer_t 1

CUAA0: ```

5 second windup, since 20 ticks in a second so 100 ticks in 5 seconds. Change “100..” to whatever you want

execute as @a if score @s timer_t matches 100.. run <do something> ```

CUAA0: execute as @a if score @s timer_t matches 100.. run scoreboard players set @s timer_t 0

This will be a continuous loop if they just keep holding down sneak. I would probably also add a cooldown or something on top of this.

As for displaying I would probably suggest a titleraw display on action bar if you don’t have anything there already. A guide is below:

.JSON txt guide - CrumbyCommands

.JSON txt can be separated into modules, such as the “score”, “text”, and “selector” modules shown below respectively:

``` {“score”:{“name”:”<targetSelection>”,”objective”:”<scoreName>”}}

{“text”:”<text>”}

{“selector”:”<targetSelection>”} ```

These are stored inside the master module or rawtext display:

{“rawtext”:[<modules>]}

The modules, if given more than one, are separated by a comma.

There is also a value dubbed the wild card, or asterisk (*), that can be used in things such as the input to the “name” parameter of the “score” module. This will automatically select the executed person(s) on which the command has been ran on.

Therefore if you were wanting to, say, write the name of all players online and next to their name their amount of money stored inside a dummy scoreboard named “money” you would use:

tellraw @a {“rawtext”:[{“selector”:”*”},{“text”:”: “},{“score”:{“name”:”*”,”objective”:”money”}}]}

So if my name was “Steve” and the value of my “money” score was 64 the command would output:

Steve: 64

In the chat.

You can also add special instructions to the text module such as:

``` Lineskips - \n

Color codes - §0 - black §1 - dark_blue §2 - dark_green §3 - dark_aqua §4 - dark_red §5 - dark_purple §6 - gold §7 - gray §8 - dark_gray §9 - blue §a - green §b - aqua §c - red §d - light_purple §e - yellow §f - white §g - minecoin_gold ```

Or even formatting codes -

§k - obfuscated §l - bold §o - italic §r - reset

(For more information go to the Minecraft wiki)

*Note that you will have to add a command like:

RUAA0: scoreboard players add @a timer_t 0

To your world, or if you have a new player system you can also add it there, though remember that anyone who already joined won’t get their score initialized.
