  1. What do you want to achieve? Keep it simple and clear!
    The title says it.
  2. What is the issue? Include screenshots / videos if possible!
    Idk how to do it and i already tried for 2 hours.
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I have tried looking tutorials, script it myself and search in the devforum.

Hey, thanks for replying i should have said this:
i want this for a gaster blaster thing, my goal its to make the gaster blaster ray to change color from really blue to really black constantly and smoothly every .2 seconds heres the code:

local c = Instance.new("Part", script.Parent)
	c.Name = "GasterBeam"
	c.Anchored = true
	c.Shape = Enum.PartType.Cylinder
	c.Size = Vector3.new(0, script.Parent.BeamCharging.Size.Y * 2, script.Parent.BeamCharging.Size.Z * 2)
	c.Material = Enum.Material.Neon
	c.Transparency = script.Parent["Beam Transparency"].Value

Or instead, just use TweenService.

--//Services
local TweenService = game:GetService("TweenService")
local Players = game:GetService("Players")

--//Variables
local part = workspace.Part -- Reference your part
local Info = TweenInfo.new(3) -- Seconds it takes to complete the tween
local Tween = TweenService:Create(part, Info, {Color = Color3.fromRGB(0, 0, 0)}) -- Colour your part will change into

--//Functions
game:GetService("Players").PlayerAdded:Connect(function(player) -- Will play the tween every time a character loads in
	player.CharacterAdded:Connect(function()
		Tween:Play()
        Tween.Completed:Wait()
	end)
end)

Yea, forgot to add that, thanks for correcting me.

For your situation do this:

local TweenService = game:GetService("TweenService")

local c = Instance.new("Part") -- You shouldn't use the second argument of Instance.new()
c.Name = "GasterBeam"
c.Anchored = true
c.Shape = Enum.PartType.Cylinder
c.Size = Vector3.new(0, script.Parent.BeamCharging.Size.Y * 2, script.Parent.BeamCharging.Size.Z * 2)
c.Material = Enum.Material.Neon
c.Transparency = script.Parent["Beam Transparency"].Value
c.Parent = script.Parent

local Tween1 = TweenService:Create(c, TweenInfo.new(0.2), {Color = Color3.fromRGB(0, 0, 0)}) -- Colour your part black
local Tween2 = TweenService:Create(c, TweenInfo.new(0.2), {Color = Color3.fromRGB(0, 0, 255)}) -- Colour your part blue

while true do
 Tween1:Play() -- Colour your part black
 Tween1.Completed:Wait()
 Tween2:Play() -- Colour your part blue
 Tween2.Completed:Wait()
end

for some reazon it doesnt work ill send the entire shoot code (what happens its that the ray doesnt appear)

while true do
	local p = Instance.new("Part", script.Parent)
	p.Name = "ChargingAura"
	p.Anchored = true
	p.CFrame = script.Parent.BeamCharging.CFrame

	p.BrickColor = script.Parent["Beam color"].Value
	p.Size = Vector3.new(script.Parent.BeamCharging.Size.X * 2.5, script.Parent.BeamCharging.Size.X * 2.5, script.Parent.BeamCharging.Size.X * 2.5)
	p.Material = Enum.Material.Neon
	p.Transparency = 1
	p.CanCollide = false
	script.Parent.Beamer.Charge:Play()

Switch my while true do loop with this.

coroutine.wrap(function()
	while true do
		Tween1:Play() -- Colour your part black
		Tween1.Completed:Wait()
		Tween2:Play() -- Colour your part blue
		Tween2.Completed:Wait()
	end
end)()

You could try using TweenService, or use Color3:lerp (which may be more resource-efficient but not as smooth and the former).

It worked, thank you so much! :slight_smile:
