Building an RPG with Unity 2018

Chapter 2. Planning the Game

In the previous chapter, you were given a good overview and historical background of RPG, and hopefully, it also sparked your imagination. In this chapter, we will start to lay the groundwork for our own RPG. We will start by defining the story of our game, as well as the plot and the quests that will make the game playable. We'll look at the assets that will be required to create our environment, characters, and finally, we'll design the levels.

The following is a breakdown of the topics we will be covering in this chapter:

  • Building our RPG
  • The story of the Zazar dynasty
  • Asset inventory
  • Level design
  • The awakening
  • Testing the level
  • Creating the main menu

Awaken your creativity and let your imagination go wild!

Building our RPG


As discussed, building a role-playing game is no small task, but once you start down the path, you will come to the realization that it is not as difficult as it seems initially. The idea is to get started, and as you put your ideas down on paper and start the design process, more and more ideas will come into perspective.

As we have learned, there are some key elements that we will need to establish for our RPG. Let's recall them, and maybe even fine-tune them as we go along.

Our game's key elements are as follows:

  • Story and setting
  • Exploration and quest
  • Items and inventory
  • Character action and abilities
  • Experience and levels
  • Combat system
  • User interface

The story of the Zazar dynasty


The premise of most role-playing games tasks the player with saving the world. There are often twists and turns as the story progresses, such as the surprise appearance of an estranged relative, or enemies who become friends and vice versa. We will create our story and game based on such a story.

Backstory

Once upon a time, there was a great kingdom, ruled by the great King Zazar. The ruler of the kingdom was a generous lord to his subjects. The kingdom under the rule of Zazar was peaceful and prosperous; however, over time, internal family rivalries and struggles caused cracks in the strong bond that kept the kingdom intact.

Due to mysterious events, the great king decided to move his family away from the kingdom and trust his son—who will become the player character—with one of the wise elders that he trusted. The kingdom was never the same... Until now!

Exploration and quests

Now that we have defined the setting for our game, we can start working on developing...

Asset inventory


Now is a good time to discuss some of the basic assets that will be required for the development of our RPG. Our game assets are defined by the scenes we describe for our game. For our RPG, we have described four unique scenes. Each one has been described in enough detail for us to get an idea of the types of assets we will require.

Environment assets

The general theme of our game will be medieval. There are several ways to go about this. The first and preferred way is to either create the environment models by yourself or a with a teammate; the second is to find a freely available model that has been created by a third party; and the third is to purchase 3D models created by a third party.

The Asset Store is a great place for you to start hunting for great content if you do not have the ability to create your own 3D models. You can use the Asset Store to search for medieval-themed environments that can be used for the game.

One of my favorites is called Medieval Environment...

Level design


Now that we have our game story on paper and have an idea of what we want to achieve, it is time to apply our skills to actually making it happen.

Note

Since this book targets an audience that is already familiar with the basics of Unity, we will not cover the fundamental aspects of the software.

To get started, we need to launch Unity. I am using the 64-bit edition of Unity 2017.x Pro. You do not need to have the Pro version of Unity to complete the project in this book. See the following screenshot:

Go ahead and select a location and a name you desire for your project, and click the Create project button. At this point, Unity will create an empty project for you and display the Unity IDE. It should look something like the following:

New project

Note

For better quality of images, download the graphics bundle from https://www.packtpub.com/sites/default/files/downloads/BuildinganRPGwithUnity2018_ColorImages.pdf

Your view might be a bit different, depending on how you have configured...

Testing the level


At some point, you will want to test out the level and look at it through the eyes of the camera. We can use the built-in third-person character controller that comes in the Standard Assets and do a quick walk-through of the level.

Note

If you did not import the Standard Assets when you created the project, you will need to import them by selecting Assets followed by Import Package|Characters.

In your Project window, you will see a folder called Standard Assets; there is a subfolder called Character Controllers. You will need to select the 3rd Person Controller Prefab and drop it somewhere on the current scene. A good location is next to the shack. Make sure that the 3rd Person Controller (3rdPC) is above the terrain so it does not fall through!

You will have to attach a Rigidbody component to the 3rdPC GameObject. This is needed to make sure that our player-character (PC) uses the built-in physics for collision detection.

Before you run the level, let's make sure the camera...

Creating the main menu


Now is a good time to create the starting point for our game. Go ahead and save the current scene. We will make a new scene that will be used as the starting point of our game. To create the new scene, you will need to select File | New Scene. Go ahead and save the scene. I called my scene MainMenu.

Now we have a clear canvas that we can work with to create our Main Menu. In the Hierarchy window, right-click and select UI | Panel. This will create a Canvas GameObject and an EventSystem GameObject, and place them in your Hierarchy window. You will notice that the Panel UI Object is a child of the canvas. All UI elements will be a child of a canvas. Your Hierarchy should look something like the following screenshot:

There are several key aspects that we want to make sure are set properly. These are namely on the Canvas GameObject. Select the Canvas GameObject and look at the Inspector Window.

For this particular canvas, make sure that the Render Mode is set to Screen Space...

Creating the GameMaster script


As discussed in Chapter 1, What is an RPG?we will need a way to manage our game. We will create a script called GameMaster. This will be the core of the game that glues everything together. As we progress with the book, you will see how we will modify the core to meet our needs.

For now, we are just going to create a simple C# script and name it GameMaster.cs. We will then create the code that will be used to handle some of the basic events we want to perform at this point, namely, navigating from scene to scene.

From your Project Window, under your scripts folder, right-click and select Create | C# Script. Name it GameMaster.cs. Double-click your script to start your code editor and place the following code in there:

using UnityEngine; using UnityEngine.SceneManagement; namespace com.noorcon.rpg2e { 
   public class GameMaster : MonoBehaviour 
   { 
 
// Use this for initialization 
      void Start() 
      { 
 
      } 
 
      // Update is called once per...

Summary


In this chapter, we have established a good sense of the RPG. We have defined our levels and the settings for each level, and defined clear objectives for each level and the outcome for each level. We also took the first level, called Awakening, and created the environment. We looked at how to use our assets and the Asset Store to incorporate 3D models in our scene. We also looked at how to plan the layout of the level. We introduced a third-person character controller into the scene to help us visualize how the level looks from the player's perspective and help us fine-tune it as needed.

Here is a list of the assets that were used for the design of this level:

  • For the terrain, I used the Terrain Toolkit 2017 asset
  • For the models within the level, I used the Medieval Environment Pack asset

By the end of the chapter, we also developed our Main Menu scene and our initial GameMaster script that will be used to glue the core of the game together. In the next chapter, we will start creating...

Does a great job going from 0-100 on everything you need to know to get started. A chapter is dedicated on how to plan building your game. Too many times people skip this important step to plan all the little details and then have to make changes later and pushing back your release date. This book covers just about everything you need to get your feel wet and learn, including lots of code, illustrations, pictures, and examples.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
