A plugin is made from a ROBLOX Folder Object. In the past plugins were simply a .lua file in the ROBLOX Plugins folder. This method is still possible but is not recommended. To make a model you can either group existing objects together or inserting a Folder object. Since the plugin is a model, it can hold any arbitrary ROBLOX object (along with a script to setup the plugin). For example, one could include other scripts or even a model of parts to copy and insert into the workspace.
an agreement between two or more parties for the doing or not doing of something specified. 2. an agreement enforceable by law. 3. the written form of such an agreement. 4. the division of law dealing with contracts.
In law, a contract (or informally known as an agreement in some jurisdictions) is an agreement having a lawful object entered into voluntarily by two or more parties, each of whom intends to create one or more legal obligations between them. bilateral contract is an agreement in which each of the parties to the contract makes a promise or set of promises to each other. For example, in a contract for the sale of a home, the buyer promises to pay the seller $200,000 in exchange for the seller's promise to deliver title to the property.
