Segments
Sets how many straight segments the Beam
is made up of.
This value can be any integer greater than 0. The default value is 10.
Beam Segments and curvature
Rather than being a perfect curve, a beam is made up of straight segments. The more segments, the higher the resoloution of the curve. See the image below for a demonstration of this:
For more information on how a Beam
is configured to curve, see the page for Beam/CurveSize0
.
Beam Segments with Color and Transparency
The Beam/Color
and Beam/Transparency
properties require a certain number of segments to display correctly. This is because each segment can only show a transition between two colors or transparencies. Therefore a Beam
requires at least n-1 segments to display correctly, where n is the number of keypoint associated with the Beam
’s Beam/Color
and Beam/Transparency
.
Code Samples
Creating a Beam From Scratch
This code sample demonstrates how a Beam
effect can be created from scratch by creating a Beam
, setting all of its properties and configuring it’s Attachment
s. See below for an image of the final result:
-- create attachments local att0 = Instance.new("Attachment") local att1 = Instance.new("Attachment") -- parent to terrain (can be part instead) att0.Parent = workspace.Terrain att1.Parent = workspace.Terrain -- position attachments att0.Position = Vector3.new(0, 10, 0) att1.Position = Vector3.new(0, 10, 10) -- create beam local beam = Instance.new("Beam") beam.Attachment0 = att0 beam.Attachment1 = att1 -- appearance properties beam.Color = ColorSequence.new({ -- a color sequence shifting from white to blue ColorSequenceKeypoint.new(0, Color3.fromRGB(255, 255, 255)), ColorSequenceKeypoint.new(1, Color3.fromRGB(0, 255, 255)) } ) beam.LightEmission = 1 -- use additive blending beam.LightInfluence = 0 -- beam not influenced by light beam.Texture = "rbxasset://textures/particles/sparkles_main.dds" -- a built in sparkle texture beam.TextureMode = Enum.TextureMode.Wrap -- wrap so length can be set by TextureLength beam.TextureLength = 1 -- repeating texture is 1 stud long beam.TextureSpeed = 1 -- slow texture speed beam.Transparency = NumberSequence.new({ -- beam fades out at the end NumberSequenceKeypoint.new(0, 0), NumberSequenceKeypoint.new(0.8, 0), NumberSequenceKeypoint.new(1, 1) } ) beam.ZOffset = 0 -- render at the position of the beam without offset -- shape properties beam.CurveSize0 = 2 -- create a curved beam beam.CurveSize1 = -2 -- create a curved beam beam.FaceCamera = true -- beam is visible from every angle beam.Segments = 10 -- default curve resolution beam.Width0 = 0.2 -- starts small beam.Width1 = 2 -- ends big -- parent beam beam.Enabled = true beam.Parent = att0
