This is a helper that stays bound to the character to detect if an enemy spawns a (sctrl) Projectile. Once the character is hit once by the enemy's projectile the data recorded can be used to find out a lot more about the projectile. Including velocity, distance, position on screen etc.
This system does NOT use any root variable but does need one blank anim.
There are plenty of notes included. If anyone thinks of a way to improve this let me know!

;==========================================================================
;notes:
;enemy projectile data can not be saved from round to round... without using root variables
;These calculations are based on the projectile needing to hit you.
;This is meant to detect one projectile at a time.
;Projectiles that stay in place may throw off projdist x.
;This does not account for proj(sctrl)s that are not used for projectiles.
;This is compatibility with Inktrebuchet's "AI Detect Projectile (helper) System"

;Base examples of trigger use:
;;Enemy's projectile helper's distance from character.
