Nedd help with character controller
Hi guys i am new to unity. i am working on a game where the character which is a ball needs to move with the help of mouse as i move mouse forward the ball goes forward and vise verca and same works for the directions mean the ball can go left and right with the help of a mouse. currently i am doing it with the help of input keys . a script would be appreciated. link for controller https://www.youtube.com/watch?v=ijGD49NmA7E
Player Controller
using UnityEngine; using System.Collections;
public class PlayerController : MonoBehaviour {
public float speed;
public GameObject camera;
void FixedUpdate()
{
float movementHorizontal = Input.GetAxis("Horizontal");
float movementVertical = Input.GetAxis("Vertical");
Vector3 movementVector = new Vector3(movementHorizontal, 0.0f, movementVertical);
movementVector = camera.transform.TransformDirection(movementVector);
GetComponent<Rigidbody>().AddForce(movementVector * speed * Time.deltaTime);
}
}
CameraController.cs
using UnityEngine; using System.Collections;
public class PlayerCameraController : MonoBehaviour {
private GameObject player;
private Vector3 offset;
private float boardTiltMax = 15f; // Maximum angle to tilt the camera to fake the level tilting
private Vector3 desiredPosition;
private GameObject desiredPositionObject;
private float rotationDamping = 10f;
private float movementDamping = 150f;
private float turnSpeed = 300f;
private float turnAngle = 0.0f;
// Use this for initialization
void Start()
{
offset = transform.position;
desiredPosition = transform.position;
desiredPositionObject = new GameObject("cameraFollow");
DontDestroyOnLoad(desiredPositionObject);
desiredPositionObject.transform.position = transform.position;
// fine the player object
player = GameObject.Find("Player");
if (player == null)
{
Debug.LogError("Could not find object \"Player\" ! Aborting GameCamera load.");
DestroyImmediate(gameObject);
}
}
void Update()
{
// Rotate the camera around the ball to adjust movement when Q or E are pressed (left/right movement)
turnAngle += Input.GetAxis("Turn") * turnSpeed * Time.deltaTime;
}
void LateUpdate()
{
// find the ZX direction from the player to the camera
var heading = transform.position - player.transform.position;
heading.y = 0f;
var distance = heading.magnitude;
var direction = heading / distance;
// Find the right vector for the diretion
var rotationVectorRight = Vector3.Cross(direction, Vector3.up);
// Move the camera
desiredPositionObject.transform.position = player.transform.position + offset;
// Rotate around the players Y axis by the turn value
desiredPositionObject.transform.RotateAround(player.transform.position, Vector3.up, turnAngle);
// Deal with forward/backward board rotation
desiredPositionObject.transform.RotateAround(player.transform.position, rotationVectorRight, -Input.GetAxisRaw("Vertical") * boardTiltMax);
// Ensure we're looking at the player before the roll rotation is applied
desiredPositionObject.transform.LookAt(player.transform.position);
// Apply the roll rotation
desiredPositionObject.transform.RotateAround(desiredPositionObject.transform.position, direction, -Input.GetAxisRaw("Horizontal") * boardTiltMax);
// Lerp the cameras position to match the target object
transform.position = Vector3.Slerp(transform.position, desiredPositionObject.transform.position, Time.deltaTime * movementDamping);
// Lerp the cameras rotation to match the target object
transform.rotation = Quaternion.Lerp(transform.rotation,
desiredPositionObject.transform.rotation,
Time.deltaTime * rotationDamping);
// Re-center the camera on the object to account for new roll rotation
CenterCameraOnTarget();
}
private void CenterCameraOnTarget()
{
Plane plane = new Plane(transform.forward, player.transform.position);
Ray ray = GetComponent<Camera>().ScreenPointToRay(new Vector3(Screen.width / 2, Screen.height / 2, 0.0f));
float distance;
plane.Raycast(ray, out distance);
var point = ray.GetPoint(distance);
var offset = player.transform.position - point;
transform.position += offset;
} }
