Vector3

Vector3 describes a vector in 3D space, typically usually used as a point in 3D space or the dimensions of a rectangular prism. Vector3 supports basic component-based arithmetic operators: sum, difference, product, and quotient. These operations can be applied on the left or right hand side to either another Vector3 or a number. It also features functions for commonly used vector operations, such as cross and dot products.

Some example usages of Vector3 are the Position, Rotation and Size of parts. Learning to set these properties are among the first things many developers will learn:

local part = workspace.Partpart.Position = part.Position + Vector3.new(5, 20, 100) -- Moves a part by this much

Vector3 is commonly used when constructing other more complex 3D data types, namely CFrame and Ray. Many of these data types’ functions will use a Vector3 within their parameters, such as CFrame:PointToObjectSpace or Ray:ClosestPoint. CFrame arithmetic also supports Vector3 for addition/subtraction.
