Getting Started with Unity 5

Before we dive into the details of building your 3D platformer, let’s take a look at what you’ll need to get started with Unity 5. First, you’ll need to download and install Unity 5 from the official website. Once installed, you’ll be prompted to create a new project. This is where you’ll give your project a name and choose the type of project you want to create (in this case, a 3D platformer).

Setting Up Your Environment

Next, you’ll need to set up your environment. This includes creating a terrain, adding lighting and setting up cameras. We’ll cover each of these steps in more detail below.

Creating Assets

Once you have your environment set up, it’s time to start creating assets for your game. Assets include anything that will be used in your game, such as characters, objects, and textures. Unity 5 has a built-in asset store where you can find pre-made assets to use in your game. Alternatively, you can create your own assets using tools like Blender or Photoshop.

Creating Assets (Continued)

One popular method for creating assets is using 2D sprites and then extruding them into 3D models. This can save time and resources as you only need to create a single asset in 2D and then extrude it into 3D. There are many free and paid tools available online that can help with this process.

Scripting in Unity 5

Now that you have your environment set up and assets created, it’s time to start scripting. Scripting is the process of writing code to control the behavior of your game. In Unity 5, scripts are written in C or JavaScript.

Basic Scripting in Unity 5

To get started with scripting in Unity 5, you’ll need to create a new script file in your project. You can do this by right-clicking in the Project window and selecting Create > C# Script or JavaScript.

Once you have your script file created, you can start writing code. Here are some basic commands you’ll need to know:

transform.position: This gets the current position of a transform object (such as a character or camera).
transform.rotation: This gets the current rotation of a transform object.
Rigidbody: This is a component that allows you to control the movement and physics of an object in your game.
Collider: This is a component that defines the shape of an object in your game.
Input: This provides access to user input, such as keyboard and mouse input.

Basic Scripting in Unity 5 (Continued)

Here’s an example script that makes a character move forward when the player presses the W key:

using UnityEngine;

public class CharacterController : MonoBehaviour
{
public float speed = 5f;

private Rigidbody rb;
private bool isGrounded;

void Start()
{
rb = GetComponent();
}

void Update()
{
if (Input.GetKeyDown(KeyCode.W))
{
isGrounded = true;
transform.position += Vector3.forward * speed * Time.deltaTime;
}

if (isGrounded && Input.GetKeyUp(KeyCode.W))
{
isGrounded = false;
rb.velocity = Vector3.zero;
}
}
}

This script assumes that you have a character object in your scene with a Rigidbody and Collider component. When the player presses the W key, the character will move forward at a speed of 5 units per second.
