In such languages, each object is an instance of a specific class. Lua does not have the concept of class; each object defines its own behavior and has a shape of its own. Nevertheless, it is not difficult to emulate classes in Lua, following the lead from prototype-based languages, such as Self and NewtonScript.
Accordingly, What is a instance in programming?
An instance, in object-oriented programming (OOP), is a specific realization of any object. An object may be varied in a number of ways. Each realized variation of that object is an instance. The creation of a realized instance is called instantiation. Each time a program runs, it is an instance of that program.

While Lua is still used fairly often in gaming and web service, it performed poorly in terms of community engagement and job market prospects. That being said, in spite of its age, Lua’s growth has flat-lined rather than declined, which means that although it’s not popular, it’s not dying either.

Is a Meshpart a BasePart?
MeshParts are a form of BasePart that includes a physically simulated custom mesh. Unlike with other mesh classes, such as SpecialMesh and BlockMesh , they are not parented to a BasePart but rather behave as a BasePart in their own right.
What is script parent?
Making the Script Reusable
To change the color of any part, use script. Parent . This command stores whatever the object is attached to. In this case, the script is attached to a part.

What is instance method?
An instance method is a method that belongs to instances of a class, not to the class itself. To define an instance method, just omit static from the method heading. Within the method definition, you refer to variables and methods in the class by their names, without a dot.
