Hello, so i made this script that generates a lightning bolt that follows a random path out of the player (https://imgur.com/a/eknhlJL , made this with the help of some free models).
Using this concept I am trying to make a wand that casts some kind of electricity spell. I want this spell to have the same kind of trail but i keep running into this issue where the variable won't change.
this is the part of the wand script that causes the problem: (NOT the full script)
local ball = Instance.new("Part", JunkStore)
ball.Name = "ball"
ball.Size = Vector3.new(0.2,0.2,0.2)
ball.Anchored = false
ball.CanCollide = false
ball.CFrame = wandtip.CFrame * CFrame.new(0,0,-0.75)
local BV = Instance.new("BodyVelocity",ball)
BV.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
BV.Velocity = mousehit.lookVector*10
wait(0.1)
PreviousB = ball.CFrame.Position
Run.Heartbeat:Connect(function()
print(PreviousB,"WAND")
On line 16 it always prints out the same number,
however if i try this on the other script that generates the trail on the player:
Object = Player.Character.HumanoidRootPart
Run = game["Run Service"]
PreviousP = Object.CFrame.p
Player.Character.Humanoid.WalkSpeed = 100
Run.Heartbeat:Connect(function()
print(PreviousP)
here it always prints out a different number
I really don't understand why the variable changes with the player's script but not with the wand's script.
If any of this is unclear just comment and i'll try to explain it further.
Thanks for trying to help!

You only update PreviousB when the tool is activated in the wand script, while you constantly update PreviousP in the bolt script using the .Heartbeat function. That's why you keep getting the same number in your wand script.
Is there a simple way to get around this ?
You can just put line 87 into the .Heartbeat function so it can constantly update.
Saddly this doesn't work doing this makes the PreviousB identically the same as ball.CFrame.p this means that (ball.CFrame.p - PreviousB).magnitude = 0 so it doesn't get past line 92
