Unity is a powerful engine that innovatively changes many aspects of modern game development. In this course, we will explain in detail how to implement a first-person perspective and add a rotation feature within that perspective. This will provide an opportunity to create your first gameplay experience in Unity.<\/p>\n<\/header>\n

\n

1. Installing Unity and Basic Setup<\/h2>\n

To use Unity, you must first download and install the Unity Hub from the official website. After installation, create a new project and select the “3D” template. The 3D template is suitable for creating perspective-based games like first-person views.<\/p>\n<\/section>\n

\n

2. Setting Up the First-Person Character Controller<\/h2>\n

To implement a first-person game in Unity, you need to set up a character controller. This allows the player to explore the game environment. Proceed to the next steps.<\/p>\n

2.1 Adding the Character Controller<\/h3>\n

Right-click in the Hierarchy window of the project and select “3D Object” > “Capsule” to create a capsule. This will be used as the player. Rename the capsule to ‘Player’.<\/p>\n

2.2 Adding a Camera<\/h3>\n

To create an actual first-person view, you need to add a camera on top of the capsule. Select the Player object, right-click, and choose “Camera” to add the camera. The camera should be placed as a child of the Capsule object.<\/p>\n

2.3 Adjusting Camera Position<\/h3>\n

Adjust the camera’s position to match the player’s head height. Generally, set the Y-axis value to 1.5. Use the Transform component to adjust the camera’s position.<\/p>\n<\/section>\n

\n

3. Implementing Rotation Functionality<\/h2>\n

Now let’s add the rotation functionality so the player can adjust the view direction. To do this, you need to write a C# script.<\/p>\n

3.1 Creating a New Script<\/h3>\n

Right-click in the Project window and select \u201cCreate\u201d > \u201cC# Script\u201d to create a new script and name it “PlayerController”. Drag this script onto the Player object to add it.<\/p>\n

3.2 Writing the Script Content<\/h3>\n

Open the PlayerController script and write the following code to implement the player’s movement and rotation features:<\/p>\n

\nusing System.Collections;\nusing System.Collections.Generic;\nusing UnityEngine;\n\npublic class PlayerController : MonoBehaviour\n{\n    public float speed = 5.0f;\n    public float sensitivity = 2.0f;\n\n    private float rotationY = 0.0f;\n\n    void Update()\n    {\n        \/\/ Rotation\n        float mouseX = Input.GetAxis(\"Mouse X\") * sensitivity;\n        float mouseY = Input.GetAxis(\"Mouse Y\") * sensitivity;\n\n        rotationY -= mouseY;\n        rotationY = Mathf.Clamp(rotationY, -90f, 90f); \/\/ Limiting view\n\n        Camera.main.transform.localRotation = Quaternion.Euler(rotationY, 0, 0);\n        transform.Rotate(Vector3.up * mouseX);\n\n        \/\/ Movement\n        float moveX = Input.GetAxis(\"Horizontal\");\n        float moveZ = Input.GetAxis(\"Vertical\");\n        Vector3 move = transform.right * moveX + transform.forward * moveZ;\n        CharacterController controller = GetComponent();\n        controller.Move(move * speed * Time.deltaTime);\n    }\n}\n<\/CharacterController><\/code>\n            <\/pre>\n
3.3 Explanation of the Script<\/h3>\n
The above code implements the following functionalities:<\/p>\n
