Execute on all players within stored distance

Question

I want to execute a command on all players withhin a distance from an armorstand (Let's call him "A"). The distance is stored in the scoreboard "Distance" for that armorstand ("Distance" of A is e.g. 13). This means that execute as @e[name=A] at @s as @a[distance=..13] ... doesn't do the trick, because the 13 is a constant here and I don't really want a command for every possible distance from 1 to 100.

I had the idea to store the distance of all players to that armorstand in their "Distance"-score and then compare the 2 scores for every player. But I don't know a way to store the distance in an scoreboard or to get it with a command.

Is there a way to do this?

Answer 1

I found a solution on YouTube:

.

Here is essentially what he is doing:

• Take first entity with as @e[tag=a], Take the second entity with at @e[sort=nearest,limit=1]
• Read and store the Position of both entities with

execute store result score @s math_in run data get entity @s Pos[0] 100

• Compute the lengths x2-x1, y2-y1, z2-z1, square and add them
• To compute the square root, he states to use the Newton-Raphson, 4 iterations approach. I don't have the math skills to quickly understand that method, but the results the datapack give are correct. To get the full list of commands, download his datapack.
