  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.

local part = Instance.new("Part")
part.Parent = workspace

while task.wait() do
	for i = 0, 255 do
		task.wait()
		part.Color = Color3.new(i, i, i)
	end
	for i = 255, 0, -1 do
		task.wait()
		part.Color = Color3.new(i, i, i)
	end
end

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)

Yes you could alternatively use TweenService, I went with a more primitive solution, however bare in mind your tween could end up playing too frequently if too many CharacterAdded events are stacked. Use the .Completed event to prevent this from happening.

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

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:
