unity first person control code example

Example 1: first person camera controller unity

//Fixed the issues with the previous controller
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraLook : MonoBehaviour
{
	public float minX = -60f;
	public float maxX = 60f;

	public float sensitivity;
	public Camera cam;

	float rotY = 0f;
	float rotX = 0f;

	void Start()
	{
		Cursor.lockState = CursorLockMode.Locked;
		Cursor.visible = false;
	}

    void Update()
    {
		rotY += Input.GetAxis("Mouse X") * sensitivity;
		rotX += Input.GetAxis("Mouse Y") * sensitivity;

		rotX = Mathf.Clamp(rotX, minX, maxX);

		transform.localEulerAngles = new Vector3(0, rotY, 0);
		cam.transform.localEulerAngles = new Vector3(-rotX, 0, 0);

		if (Input.GetKeyDown(KeyCode.Escape))
		{
        	//Mistake happened here vvvv
			Cursor.lockState = CursorLockMode.None;
			Cursor.visible = true;
		}

		if (Cursor.visible && Input.GetMouseButtonDown(1))
		{
			Cursor.lockState = CursorLockMode.Locked;
			Cursor.visible = false;
		}
	}
}

Example 2: first person view unity

// C Sharp
public Transform followTarget;
public Vector3 targetOffset;
public float moveSpeed = 2f;
private Transform myTransform;

void Start(){
 myTransform = transform; 
}

public void SetTarget(Transfrom aTransform){
 followTarget = aTransform; 
}

void LateUpdate(){
 if(followTarget != null){
  	myTransform.position = Vector3.Lerp(myTransform.position, followTarget.position + targetOffset, moveSpeed * Time.deltaTime); 
 }
}
