Sure! Here’s a script that will move the first-person camera in a first-person game in Unity using the Rigidbody component:

using UnityEngine; public class FirstPersonController : MonoBehaviour { public float speed = 5.0f; // Use this for your first-person camera public Rigidbody rb; // Update is called once per frame void Update() { float horizontalInput = Input.GetAxis("Horizontal"); float verticalInput = Input.GetAxis("Vertical"); // Calculate the new horizontal and vertical movement based on the inputs float newHorizontal = horizontalInput * speed * Time.deltaTime; float newVertical = verticalInput * speed * Time.deltaTime; // Set the new camera movement rb.transform.position += new Vector3(newHorizontal, newVertical, 0); } }

In this script, we first import the Rigidbody component. We’ll use this to control the camera’s movement.



Next, we define a public float speed variable to control the speed of the camera movement.


Next, we create a public Rigidbody rb variable and set it to null. This is used to track the current camera’s movement.



Next, we have an Update method that calculates the new camera movement based on the user’s horizontal and vertical inputs. We multiply the user inputs by a constant speed, and then call the Time.deltaTime method to update the movement speed over time.

Finally, we use the rb.transform.position property to set the new camera movement. The value we assign to this property is the sum of the old camera movement and the new camera movement.



That’s it! With this script, you can control the movement of the first-person camera in your Unity game.
