I show how to use Vector3's in Roblox in this video, and I answer the question what is a Vector3. A Vector3 is a datatype in Roblox that contains 3 numbers. The numbers can represent anything, but they often are used to represent the Position, Rotation, and Size of parts. This video explains the coordinate system in Roblox, how to create a Vector 3 with Vector3.new, how to get the X, Y, and Z component of a Vector, as well as how to add, subtract, and multiply vectors.
