Bullet collision

[i8bit]

I am making a new shooting system.
How can I trigger an action of my baddie when it collides with the temp.npc("Bullet")
--(trigger "onHurt")

With that, how do I check if a player is within the x,y of the bullet for player collision?

(onPlayerTouchsMe) will only work when player runs into bullet. Not vise-versa.
