It's just phasing like the flash.

local counter = 0
local ref = script.Parent.Parent.Ref
local function increaseHeight(part, amount, amount2, neg)
    amount2 = amount *counter
    local refo = script.Parent.Parent.Ref.CFrame
    part.Size += Vector3.new(0,amount,0)
    part.CFrame = refo+Vector3.new(0, 0, 0)
    part.CFrame *= CFrame.new(0,-amount2/2,0)
    if neg == 1 then
    counter += 1
    else
        counter -= 1
    end
end

while task.wait() do
    local w = 0
    local touchingparts = script.Parent:GetTouchingParts()
    if #touchingparts > 0 or Light.Size.Y >= 33 then
    w = -1
    increaseHeight(Light, w, w, 1)
    else
        w = 1
        increaseHeight(Light, w, w, 0)
    end
    end```

I was trying to make collision

and have the beam shrink

whenever it hits something

but

it like

became sentient or something and found a workaround

and instead it just goes around objects

oh no wait it's not going AROUND, It's just going... on the wrong side of the object??? yeah because it's 2 beams

and one has no collision cas it's decorative, the first one, makes the beam look smoother

yeah so the second one which has the code is just going on the wrong side entirely

this is what it's SUPPOSED to do, but it flashes between the one side and the other

and sometimes the beam just leaves entirely :(

straight deletes itself

please someone help me I am so confused

I'm gonna go take out the garbage now

[past peak]

the flash i see is in my eyes after i look at your white mode post

[clear dome]

It's scripting wdym
