Hi, I have a beam for my npc and want it do detect if players who are in the beam. I do not know what the best way to have the most accurate reading however

Look Vector would be handy. You could also use raycasting.
Raycasting would be the best way to do this.
How would I use raycasting, isnt it a small ray?
Check out this article.
Will the ray be like the beams width?
Raycasts have no width. They are an infinitely thin ray with finite length.
Is it possible I can make it wider to fit the beam?
Like I said, no. You can’t change the width of a raycast.
So what else can I do to make the beam as accurate
A raycast would be fine for this in my opinion.
You could also do 4 raycasts to sort-of make a rectangle that covers the entire beam.
Or you could use a region3 at the end of the beam. But that seems like a really crude way to do it imo.
If you’re not gonna use raycast, my only suggestion would be to make transparent massless parts that are the size/position of the beam, and write a function that gets the player’s humanoid based off who’s touching the massless parts.
Although that can be somewhat tedious.
Another way to do this is to create a ray from the npc’s head to the head of each player. The player is detected if nothing is obscuring the ray and the ray is within a certain angle from the lookvector of the npc’s head.
If it was for a player, just add a ImageLabel for such player and that’d be the “crosshair”, where everything would be detect. But since this is for a NPC, I guess you should use raycasting and that stuff. Or just make it so anything that touches the beam, if it is a humanoid then start damaging, or whatever you need. I do not know how to make it so it can’t see through walls, however. You should make it so if the object detected is a part or union and isn’t along with a humanoid object, then shorten the beam to the wall.
Raycasting. But you could also use,
Region3:Dot()Object.Touched
magnitude or overlaps and then drag the beam’s attachment using tween to the target
