\n Unity is a powerful engine for game development that provides the ability to create a variety of 2D and 3D applications.
\n In this course, we will cover how to rotate the camera’s view up and down in Unity.
\n Through this process, you will learn how to manipulate the player\u2019s viewpoint and, further, provide an immersive experience within the game.\n<\/p>\n
\n First, launch Unity and create a new project. \n To set up the player character, select 3D Object<\/strong> > Cylinder<\/strong> from the GameObject<\/strong> menu to create a basic character model. \n To implement the up and down rotation of the camera, we will write a script for input processing. Create a folder named Scripts<\/strong> inside the Assets<\/strong> folder, and \n After writing the script, select the Main Camera<\/strong> object, click the Add Component<\/strong> button, and add the CameraController<\/strong> script you created. \n Now that all settings are complete, save the scene and click the play button to test the game. \n In addition to basic up and down rotation, you can add more diverse features to provide a better user experience.
\n Select the 3D project and set an appropriate project name. After the project is launched, configure the basic scene.
\n In the scene view, select the Main Camera<\/strong> object and adjust the camera’s position and rotation angles.
\n The camera serves as the reference to display all game objects, so it must be properly set.\n<\/p>\n2. Setting Up the Camera and Player Character<\/h2>\n
\n This object will become a simple form of the player character. Rename the created cylinder to ‘Player’, and
\n set the Main Camera<\/strong> as the child of the player.
\n This will allow the camera to move with the player.\n<\/p>\n3. Setting Up the Input System<\/h2>\n
\n create a script named CameraController.cs<\/strong> within it.
\n Paste the following code into the script:\n<\/p>\n\nusing System.Collections;\nusing System.Collections.Generic;\nusing UnityEngine;\n\npublic class CameraController : MonoBehaviour\n{\n public Transform player; \/\/ Player character\n public float sensitivity = 5.0f; \/\/ Mouse sensitivity\n public float clampAngle = 80.0f; \/\/ Rotation limit angle\n\n private float rotX = 0.0f; \/\/ Up and down rotation angle\n private float rotY = 0.0f; \/\/ Left and right rotation angle\n\n void Start()\n {\n rotX = transform.localEulerAngles.x; \/\/ Set initial up and down rotation angle\n rotY = transform.localEulerAngles.y; \/\/ Set initial left and right rotation angle\n\n Cursor.lockState = CursorLockMode.Locked; \/\/ Hide the mouse cursor\n }\n\n void Update()\n {\n rotX -= Input.GetAxis(\"Mouse Y\") * sensitivity; \/\/ Calculate up and down rotation with mouse Y input\n rotY += Input.GetAxis(\"Mouse X\") * sensitivity; \/\/ Calculate left and right rotation with mouse X input\n\n rotX = Mathf.Clamp(rotX, -clampAngle, clampAngle); \/\/ Limit the rotation angle\n\n transform.localEulerAngles = new Vector3(rotX, rotY, 0); \/\/ Apply rotation\n player.Rotate(0, Input.GetAxis(\"Mouse X\") * sensitivity, 0); \/\/ Apply left and right rotation to the player character\n }\n}\n<\/code><\/pre>\n
\n Then drag the Player<\/strong> object to the Player<\/strong> property of the CameraController<\/strong> script to link it.\n<\/p>\n4. Testing and Adjusting<\/h2>\n
\n You can see the camera rotating up and down as you move the mouse, and the player character rotating left and right.
\n If you want to adjust the sensitivity, you can change the value of the sensitivity<\/strong> variable to achieve your desired sensitivity.\n<\/p>\n5. Implementing Additional Features<\/h2>\n
\n For example, you can use the SmoothDamp<\/strong> function to smooth the camera’s movement.\n<\/p>\n\nprivate Vector3 velocity = Vector3.zero; \/\/ Velocity variable\n\nvoid LateUpdate()\n{\n Vector3 targetPosition = player.position; \/\/ Target position\n transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref velocity, 0.3f); \/\/ Smooth camera movement\n}\n<\/code><\/pre>\n
