First Person Engine in 265 Lines of Code

A first person engine is a type of game engine that allows players to experience a game from the perspective of the protagonist. This type of engine is often used in first-person shooter games, but it can also be used in other genres, such as adventure games and role-playing games.

First person engines are typically written in C++ or C, and they use a variety of libraries and frameworks to provide features such as rendering, physics, and animation.

In this article, we will show you how to create a first person engine in 265 lines of code. We will use the Unity game engine, which is a free and open-source game engine that is ideal for creating first person games.

Creating the Project

The first step is to create a new project in Unity. To do this, open the Unity Hub and click the New button. Then, select the 3D template and click the Create button.

This will create a new project folder in your Documents folder. Inside the project folder, you will find a file called Assets. This folder contains all of the files that make up your game, including the scenes, models, and scripts.

Creating the Scene

The next step is to create a scene. To do this, click the Scene button in the Unity editor toolbar. This will open the Scene view, which shows a 3D representation of your game world.

To add a 3D object to your scene, click the Add button in the toolbar and select 3D Object. This will open a list of 3D objects that you can add to your scene.

For this tutorial, we will add a simple cube to our scene. To do this, select the Cube object from the list and click the Add button. This will add the cube to your scene.

Creating the Camera

The next step is to create a camera. A camera is used to render the game world from the perspective of the player.

To create a camera, click the GameObject button in the toolbar and select Camera. This will create a new camera object in your scene.

The camera object will be automatically added to the scene hierarchy. The scene hierarchy is a list of all of the objects in your scene, organized by their parent-child relationship.

Setting the Camera’s Position

The next step is to set the camera’s position. The camera’s position determines where the player will be looking in the game world.

To set the camera’s position, select the camera object in the scene hierarchy and use the transform tools in the toolbar to move it around.

Creating the Player Controller

The next step is to create a player controller. A player controller is a script that controls the player’s movement and actions in the game.

To create a player controller, click the Create button in the toolbar and select C Script. This will create a new C script file in your project.

Rename the script file PlayerController.

Open the PlayerController script file and add the following code:

“`
using UnityEngine;

public class PlayerController : MonoBehaviour {

private float _moveSpeed = 5.0f;

private void Update() {
// Move the player in the direction of the mouse cursor.
Vector3 movement = Input.mousePosition – transform.position;
movement.y = 0.0f;
movement = movement.normalized _moveSpeed Time.deltaTime;
transform.position += movement;
}
}
“`

This code will move the player in the direction of the mouse cursor. The speed of the player’s movement is controlled by the _moveSpeed variable.

Attaching the Player Controller to the Cube

The next step is to attach the player controller to the cube. To do this, select the cube object in the scene hierarchy and drag the PlayerController script onto it.

This will attach the PlayerController script to the cube object.

Running the Game

The final step is to run the game. To do this, click the Play button in the Unity editor toolbar.

This will start the game and you will be able to control the cube object from the first person perspective.
