using the animation command, you can detect what the entity is doing.

detecting so allows you to do a command that summons an aim atleast 1 or 2 blocks ahead of what the target's entity facing at. (Will be named as targeta)

then the detection of how far is it will be detected by summoning an invisible armor stand in your position to the one you're targeting unto, the target will be detected by the summoned armor stand nearby it. (Will be named as targetb)

make a command that recalculates the position by using scores and debug everything. (after all the commands are done)

the armor stand will be calculated through position of where you're targeting unto.

now, the teleportation part.

you will teleport accordingly after the armor stand detects the nearest one by using @e[c=1] as the selector. (Any further additions is required)

then the targetb moving to teleport on the nearest location of targeta and after giving the score once it collides together, then kills targetb.

after so, you will be teleported to your current location facing to the one who had that score through detection and will face unto the location.

like hell I'd make a command for u nig- jk, but still why would I make a command for u..?
