Projectile damages caster

Help and Feedback Code Review
#1

I’m making a magic game and I’ve started scripting a simple projectile, I use a RaycastHitbox module for the projectile and it works perfectly
Though the projectile is also damaging the caster and I have no idea how to fix it

Module: Raycast Hitbox 4.01: For all your melee needs!
Script inside of the projectile:

local RS = game:GetService("ReplicatedStorage")
local RAYCAST_HITBOX = require(RS.RaycastHitboxV3)

local newHitbox = RAYCAST_HITBOX:Initialize(script.Parent)

newHitbox.OnHit:Connect(function(hit, humanoid)
    humanoid:TakeDamage(5)
    script.Parent:Destroy()
end)


newHitbox:HitStart()

Firstly, you’re in the wrong category. Would fit more in Scripting Support. To answer your problem, in the Initialize function, add another argument with a table. Put an instance into the table to make the script ignore that instance and its descendants.

Example:

local ignoreList = {character}
local newHitbox = RAYCAST_HITBOX:Initialize(script.Parent, ignoreList)
