Implement data persistence between scenes

Implement data persistence between sessions

Quiz: Manage scene flow and data

Submission: Data persistence in a new repo

Learn about data persistence and an introduction to the core pillars of object-oriented programming.

In this mission, you’ll learn about data persistence, or how to manage the loading and unloading of data between both scenes and sessions. Along the way, you will be introduced to the core pillars of object-oriented programming, which will help you structure your code throughout the mission. There will only be one practical example throughout the mission, which will build on the new functionality you create with each tutorial. At the end of this mission, you’ll take everything you learned and apply it to a new project by building a persistent score system for a small game.

In this Mission, you will program a game to test the player’s reflexes, where the goal is to click and destroy objects randomly tossed in the air before they can fall off the screen. In creating this prototype, you will learn how to implement a User Interface - or UI - into your projects. You will add a title screen with a difficulty select menu that will control how challenging the gameplay is, you will add a score display that will track how many points the player has earned, and you will add a Game Over screen, which will allow the player to restart and try again. In learning these skills, you will be able to create a fully “playable” experience that the user can enjoy from start to finish without having to restart the application to try it again.

Deep-dive into the pillars of object-oriented programming and their application, then learn how to profile and optimize code.

In this mission, you’ll refactor the inventory project you completed in the previous mission using the pillars of object-oriented programming as a guide. You’ll deep dive into the inner workings of each pillar individually, so you can better understand its value in developing applications. Next, you’ll learn how to profile your code to identify any optimization bottlenecks that would slow down the final build of your application. To close out this mission, you’ll develop a small application for your portfolio that uses fully optimized code built on OOP principles.

Junior Programmer: Manage scene flow and data

Now that you’ve set up version control, you’re ready to explore the main project that you’ll use to both practice programming and connect the principles of object-oriented programming (OOP) with your own code.

Before you continue, open the version of the project that you created in the previous tutorial:

1.  Check that you have installed Unity 6 LTS or higher. If it’s not installed, a warning notification will be displayed below its listing in the Unity Hub with a prompt to install the correct version. 

The Unity project you will be working on is a resource management simulation application. Resource management is at the heart of a popular genre of games, but these simulations are also commonly used in educational contexts (for example, to explore sustainability and economics) and in industry. 

This type of project is a particularly good fit to help you explore programming systems and architecture, as they often include:

User interaction, to enable them to influence the simulation

Transitions between scenes, to enable further customization by the user

Systems designed for extension, to increase the complexity of the simulation

The warehouse-themed simulation that is the core of the resource management application

We have provided a basic resource management simulation in this project. Let’s take a moment to explore it:


1.  In the Project window, go to Assets > Scenes and open the Main scene. 


2.  Select Play to enter Play mode and review the simulation.

Two different types of Resource Pile (objects on a pallet), which both produce resource items at a speed of 0.5 per second



Three Transporter Units (forklifts), which transport resources to a defined base (the space in front of the truck marked with a red circle)

Left-click any Transporter Unit or Resource Pile to bring up a user interface information overlay with its details. 


Note: You can use your arrow keys (or WASD) to move the camera around the warehouse space.

4.  Left-click a Transporter Unit — a green arrow icon will appear above it to indicate that you have selected it.

5.  Right-click one of the two Resource Piles. The Transport Unit will begin moving towards the Resource to collect its resource units and transport as much as it can carry to the drop point.

6.  Experiment with what you can do with the Transport Units! Try sending one to a different place in the warehouse or changing its associated Resource Pile when it’s active. 

7.  When you’ve finished, remember to select the Stop button to exit Play mode.  

An overlay window is open in the upper-left of the Scene view; a green arrow is visible over the Transporter Unit center bottom of the Scene view.

Now that you’ve reviewed the basic functionality of the simulation, it’s time to go deeper. We’ve created a project brief, which will guide you through:

The basic functionality of the simulation

The additional functionality you’ll implement over the next two missions in this pathway

Take some focused time to go through the brief:

2.  Review the document with the project open in Unity Editor, so you can refer to the project as you do so. 

3.  You might find it useful to open the script files and explore them in more detail — how much do you know about what they do, based on your previous work in this pathway?

In this mission, you’ll focus on getting the application functionality working. You’ll implement:

The necessary scene flow and user interface buttons

Data persistence between scenes, so the user can choose a color in the starting menu and apply it to the Transporter Units (forklifts) in the simulation

Data persistence between sessions, so the last color a user chooses is pre-selected when they launch the application again

For your final submission, you’ll apply your learning and implement data persistence in a simple game project. 

In the next mission, you’ll then focus on object-oriented programming principles as you refine code and add new functionality to the simulation.

Want to customize as you go? Please do! Although the focus of this mission is Programming Systems and Architecture, you’ll find opportunities here to customize the project and consolidate your skills you learned in previous missions — we’ll highlight some clear opportunities for you, but take initiative and be bold!

Remember, this project brief is a resource that’s available to you throughout this learning experience. Refer back to it if you need to refresh your memory of the project, or want to get a high level view of what you’ll be working on.


In the next tutorial, you’ll explore the basic principles of object-oriented programming that underpin your work in this second half of the Junior Programmer pathway.
