Assignment 1: Kaiten-Zushi 3D

Introduction

This assignment will be the first Unity project you develop on your own, after having completed

Assignment 0 and Assignment 0.5 . You will be using Unity 2018.3 and C# to design a 3D scene

containing objects with which the user can interact using your mobile device’s touchscreen.

Your scene will be a kaiten-zushi (conveyor belt sushi) fast-food restaurant. Unlike restaurants

of this type that use a single conveyor belt whose technology is essentially a scaled-down

version of airline baggage-claim conveyor belts, your restaurant will use four straight conveyor

belts, as described below. (Yes, this is a poor design, but it will help turn your program into an

entertaining game.) In addition, there will be a chef, plates of food, tables, and trays.

Since we do not want you to have to create your own 3D models, you can download models

(free ones only, please) for all objects in your scene from the Unity Asset Store , or any other

source (e.g., the ones listed on our IA page ), providing you have permission and cite each

source properly in your documentation. Alternatively, you can load a model ( .fbx file, .obj file, or

other supported formats ) obtained elsewhere by dragging its file into the Project View in the

Unity Editor Window. Any associated textures should be added to a “Textures” folder placed

next to the loaded model in the Project View. You can also import an entire directory at once.

While you are also welcome to create any of your objects directly from Unity primitives , you

should use at least one downloaded model. Again, any model that you use must be free.

Conveyor Belts, Trays, Chef, and Tables

There should be four conveyor belts arranged in a rectangle, as shown in Figure 1. All four belts

are identically sized cuboids whose top surfaces are parallel to the world xz -plane. The

conveyor belts do not need to be textured and do not need to move. That is, they do not have to

actually behave like real moving belts: Only the plates of food will need to move! The conveyor

belts are not connected to each other. Instead, there are four stationary trays at the corners of

the rectangle bordered by the belts. The trays should be the same height as the belts.

Within the space surrounded by the belts there should be a chef. Outside the conveyor belts,

there should be at least four tables. On the conveyor belts there will be sushi plates, special

plates, and dessert plates that move along the paths defined by the belts.
