6.4 Camera Management

The camera plays a critical role in determining how players view and interact with the game world.

Step 1: First-Person Camera

• Attach a camera to the player object at head height.
• Write a script to rotate the camera based on mouse input:

public float mouseSensitivity = 100f;
private float xRotation = 0f;

void Update() {
    float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
    float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

    xRotation -= mouseY;
    xRotation = Mathf.Clamp(xRotation, -90f, 90f);

    transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
    playerBody.Rotate(Vector3.up * mouseX);
}

Step 2: Third-Person Camera

• Position the camera behind the player.
• Use a script to make the camera follow the player smoothly:

public Transform player;
public Vector3 offset;

void LateUpdate() {
    transform.position = player.position + offset;
    transform.LookAt(player);
}

Step 3: Cinematic Camera

• Use Unity’s Cinemachine package for advanced camera behaviors.
• Create cinematic shots, such as cutscenes or dynamic zooms.

Activity: Implement and switch between a first-person and third-person camera system.

Summary of Module 6

By the end of this module, you will:

• Be able to create immersive 3D environments using terrain, lighting, and skyboxes.
• Understand the principles of level design and asset placement.
• Build a 3D character controller with custom movement and animations.
• Implement different camera perspectives for a more dynamic player experience.

With these skills, you’ll be prepared to create stunning and functional 3D games!
