How to make a deflectable projectile (with detecting a player looking at an entity, kinda)

I am making a wind-charge-inspired projectile for my mod in 1.20.1 and wanted to make it deflectable. Luckily, I was able to achieve this with procedure blocks that you need only 2 plugins for and with the help of one post on the forum.
The plugins you will need are Snails' plugin and Procedures+

the post that helped me (with Evistix's example) is here: https://mcreator.net/forum/103087/how-can-i-create-scp-096-minecraft-11…
