Functions

Function Name Return Type Description Tags
GetNormalized() Vector4 Returns a new Vector4 with size 1, but still pointing in the same direction. Returns (0, 0, 0, 0) if the vector is too small to be normalized. None
GetAbs() Vector4 Returns a new Vector4 with each component the absolute value of the component from this Vector4. None

Class Functions

Class Function Name Return Type Description Tags
Vector4.Lerp(Vector4 from, Vector4 to, number progress) Vector4 Linearly interpolates between two vectors by the specified progress amount and returns the resultant Vector4. None

This example shows how a Color can be converted into a Vector4, which opens the possibility of some math operations that are available to the latter.

function ColorToVector4(color)
    local v = Vector4.New()
    v.x = color.r
    v.y = color.g
    v.z = color.b
    v.w = color.a
    return v
end

function GetMagnitudeOfColor(color)
    local v = ColorToVector4(color)
    return v.size
end
