TextureLength

Property of: Beam

Value Type: float

Description:

Sets the length of the Beams texture if Beam/TextureMode is ‘Wrap’ or ‘Static’. If Beam/TextureMode is ‘Stretch’ then it determines the size of the texture relative to the Beam's length.

Beam texture behavior

How a Beam|Beam's texture scales or repeats is dependent on the Beam/TextureMode property.

When Beam/TextureMode is ‘Wrap’ the size of the repeating texture is equal to TextureLength in studs. For an example of this see the image below:

beamTexture1

Note, the ‘Static’ Enum/TextureMode type is not used for Beams and therefore behaves identically to ‘Wrap’.

When Beam/TextureMode is set to ‘Stretch’ however the texture will be stretched relative to the beam’s length. The size of the texture relative to the Beam's length will be one over the TextureLength. In practice, this means the texture will repeat TextureLength times. For an example of this see the image below:

beamTexture2

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 Attachments. See below for an image of the final result:

att0.Position = Vector3.new(0, 10, 0)
att1.Position = Vector3.new(0, 10, 10)

beam.LightInfluence = 0 -- beam not influenced by light

)
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
