How to make my character look in the direction of the camera in Unity 3d?

My character has a chinemachine camera attached to it and it is moving perfectly fine. But when I move my mouse to change the camera direction it is not looking in that direction. And I can't figure out how to make it look in that direction.
I have a reference to the original camera at the top of the script by the name cam.
The script has different functions for movement, rotation, animation, etc.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//so that unity recognises the callbacks ctx passed to the movementinput
using UnityEngine.InputSystem;
public class AnimationAndMovController : MonoBehaviour
{
public Transform cam;
public float speed;
//here we are creadting three vars for the animation
//vector2 currentMovementInput stores the input axis of the player
//vector3 store the current position of the player
PlayerInput playerInput;
CharacterController characterController;
Animator animator;
Vector2 currentMovementInput;
Vector3 currentMovement;
Vector3 currentRunMovement;
Vector3 moveDir;
bool isMovementPressed;
bool isRunPressed;
float rotationFactor = 15.0f;
// float turnSmoothtime = 0.1f;
// float turnSmoothVelocity ;
float runMultiplier = 4.0f;
int walkHash ;
int runHash ;
//runs before start function
void Awake(){
playerInput = new PlayerInput();
characterController = GetComponent<CharacterController>();
animator = GetComponent<Animator>();
// walkHash = Animator.StringToHash("Walking");
// runHash = Animator.StringToHash("run");
//now instead of writing the logic three times we pass the callback ctx to the movementInput() function
playerInput.CharacterControls.Move.started += movementInput;
playerInput.CharacterControls.Move.canceled += movementInput;
playerInput.CharacterControls.Move.performed += movementInput;
playerInput.CharacterControls.Run.started += handleRun;
playerInput.CharacterControls.Run.canceled += handleRun;
}
void handleRun(InputAction.CallbackContext ctx){
isRunPressed = ctx.ReadValueAsButton();
}
//we are going to handle rotations with quaternions
void handleRotation(){
Vector3 positionToLookAt;
positionToLookAt.x = currentMovement.x;
positionToLookAt.y = 0.0f ;
positionToLookAt.z = currentMovement.z;
Vector3 direction = new Vector3(positionToLookAt.x, 0.0f, positionToLookAt.z).normalized;
Quaternion currentRotation = transform.rotation;
//we take the current rotation and the target rotation and slerp them *FYI : Im still not sure how slerp works
if(isMovementPressed){
Quaternion targetRotation = Quaternion.LookRotation(positionToLookAt);
transform.rotation = Quaternion.Slerp(currentRotation, targetRotation, rotationFactor * Time.deltaTime);
}
}
//we are passing the callback ctx to this function so that we dont have to call the function everytime we start, cancel or perform the movement
void movementInput(InputAction.CallbackContext ctx){
//we are setting the movement input to the axis of the player
currentMovementInput = ctx.ReadValue<Vector2>();
currentMovement.x = currentMovementInput.x;
//we are setting the z axis to the y axis of the player because we move y axis on keyboard or joystick but in game we move in z axis
currentMovement.z = currentMovementInput.y;
//now we are setting the run movement to the current movement
currentRunMovement.x = currentMovementInput.x * runMultiplier;
currentRunMovement.z = currentMovementInput.y * runMultiplier;
isMovementPressed = currentMovementInput.x != 0 || currentMovementInput.y != 0;
}
void handleAnimation(){
bool walk = animator.GetBool("walking");
bool run = animator.GetBool("run");
if(isMovementPressed && !walk){
animator.SetBool("walking", true);
}
else if(!isMovementPressed && walk){
animator.SetBool("walking", false);
}
if((isMovementPressed && isRunPressed) && !run){
animator.SetBool("run", true);
}
else if((!isMovementPressed || !isRunPressed)&& run){
animator.SetBool("run", false);
}
}
void handleGravity(){
//we are setting the gravity to -9.8f because we are moving in y axis
if(characterController.isGrounded){
float groundGravity = -0.05f;
currentMovement.y = groundGravity;
currentRunMovement.y = groundGravity;
}
else{
float gravity = -9.8f;
currentMovement.y += gravity * Time.deltaTime;
currentRunMovement.y += gravity * Time.deltaTime;
}
}
// Update is called once per frame
void Update()
{
handleAnimation();
handleRotation();
handleGravity();
if(isRunPressed){
characterController.Move(currentRunMovement * Time.deltaTime);
}
else{
characterController.Move(currentMovement * Time.deltaTime);
}
}
//we are checking if the player script gets enabled or disabled and accordingly we are enabling or disabling the player input
void OnEnable(){
playerInput.CharacterControls.Enable();
}
void OnDisable(){
playerInput.CharacterControls.Disable();
}
}

That quite a lot of code to dive into.
I'd try:
Quaternion cameraRot = Camera.Main.transform.rotation;
transform.rotation = cameraRot;
Or if you have a target Quaternion.LookRotation:
Vector3 relativePos = target.position - transform.position;
// the second argument, upwards, defaults to Vector3.up
Quaternion rotation = Quaternion.LookRotation(relativePos, Vector3.up);
transform.rotation = rotation;
Hope that helps

Use Transform.LookAt, which points a Game Object's rotation towards a target's position.
In your case, this would be
transform.LookAt(cam);

here is the code that I use..
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveCamera : MonoBehaviour
{
public float sensitivity = 1000f;
public float xRotation = 0f;
public Transform playerBody;
public Quaternion localRotate;
// Start is called before the first frame update
void Start()
{
Cursor.lockState = CursorLockMode.Locked;
}
// Update is called once per frame
void Update()
{
float MX = Input.GetAxis("Mouse X")*sensitivity*Time.deltaTime;
float MY = Input.GetAxis("Mouse Y")*sensitivity*Time.deltaTime;
xRotation -= MY;
xRotation = Mathf.Clamp(xRotation,-90f,90f);
transform.localRotation = Quaternion.Euler(xRotation,0f,0f);
localRotate = transform.localRotation;
playerBody.Rotate(Vector3.up * MX);
}
}
the player body you see is the player object to you character...
note that the camera is use is not In. cinema chine and is inside of the player...

Need support with Unity Enging C# Scripts for Player Movement

I've been recently working on a project using Unity Engine that involves a sort of Top-Down, 3rd person view, and I have been having trouble with the character movement.
I want to implement a way for the player to move throughout the map using either WASD movement, Click-to-Move movement, or Drag-to-Move movement, allowing them to use either of these freely and at any time, yet I have not yet found a way of doing this, since the methods end up cancelling each other out, leading the Player Character to awkward movement and to getting stuck in place.
Is there any way of achieving this? If so, any tips/suggestions would be greatly appreciated. Please keep in mind I am a complete beginner when it comes to both Unity and C#, so I might not grasp some core concepts yet.
I have attached my PlayerMovement C# code below.
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
[RequireComponent(typeof(test))]
public class PlayerMovement : MonoBehaviour
{
private test _input;
//click2move
private NavMeshAgent agent;
//x
[SerializeField]
private bool RotateTowardMouse;
[SerializeField]
private float MovementSpeed;
[SerializeField]
private float RotationSpeed;
[SerializeField]
private Camera Camera;
void Start()
{
//c2m

//x
}
private void Awake()
{

}
// Update is called once per frame
void Update()
{
var targetVector = new Vector3(_input.InputVector.x, 0, _input.InputVector.y);
var movementVector = MoveTowardTarget(targetVector);
agent.autoBraking = true;
if (!RotateTowardMouse)
{
RotateTowardMovementVector(movementVector);
}
if (RotateTowardMouse)
{
RotateFromMouseVector();
}
//c2m
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit))
{
if (Input.GetMouseButtonDown(0))
{
agent.SetDestination(hit.point);
}
}
else
{
if (agent.remainingDistance < 1)
{
agent.ResetPath();
}
}
}
private void RotateFromMouseVector()
{
Ray ray = Camera.ScreenPointToRay(_input.MousePosition);
if (Physics.Raycast(ray, out RaycastHit hitInfo, maxDistance: 300f))
{
var target = hitInfo.point;
target.y = transform.position.y;
transform.LookAt(target);
}
}
private Vector3 MoveTowardTarget(Vector3 targetVector)
{
var speed = MovementSpeed * Time.deltaTime;
// transform.Translate(targetVector * (MovementSpeed * Time.deltaTime)); Demonstrate why this doesn't work
//transform.Translate(targetVector * (MovementSpeed * Time.deltaTime), Camera.gameObject.transform);
targetVector = Quaternion.Euler(0, Camera.gameObject.transform.rotation.eulerAngles.y, 0) * targetVector;
var targetPosition = transform.position + targetVector * speed;
transform.position = targetPosition;
return targetVector;
}
private void RotateTowardMovementVector(Vector3 movementDirection)
{
if (movementDirection.magnitude == 0) { return; }
var rotation = Quaternion.LookRotation(movementDirection);
transform.rotation = Quaternion.RotateTowards(transform.rotation, rotation, RotationSpeed);
}
}

I would highly recommend that you use the Unity Input System. It can automate switching between input devices and decouple your code from any specific controls. It might be a bit overwhelming if you have limited experience with C#, but there is a vast library of tutorial videos and written guides you can rely on.
The PlayerInput component is what detects when different input devices are added or removed and switches to the first valid control scheme. When a user activates the inputs required to trigger something in your game, that is represented as an Action. A set of callbacks for that action are called depending on the states of the input: started, performed, and canceled. These are where you hook up your character controller to the input and run any extra logic necessary to turn an input into movement. The Input System also has a feature called interactions that will probably be useful, especially for drag-to-move controls.
Good luck! If you'd like me to explain something further or point you to a good tutorial, feel free to tag me in a comment.

First create a Capsule in the scene, drag the main camera to its object, hang the script under the Capsule object, WASD controls the movement direction, the space moves up along the Y axis, and the F moves down along the Y axis, thank you
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveCam : MonoBehaviour
{
private Vector3 m_camRot;
private Transform m_camTransform;//Camera Transform
private Transform m_transform;//Camera parent object Transform
public float m_movSpeed=10;//Movement factor
public float m_rotateSpeed=1;//Rotation factor
private void Start()
{
m_camTransform = Camera.main.transform;
m_transform = GetComponent<Transform>();
}
private void Update()
{
Control();
}
void Control()
{
if (Input.GetMouseButton(0))
{
//Get the mouse movement distance
float rh = Input.GetAxis("Mouse X");
float rv = Input.GetAxis("Mouse Y");
// rotate the camera
m_camRot.x -= rv * m_rotateSpeed;
m_camRot.y += rh*m_rotateSpeed;
}
m_camTransform.eulerAngles = m_camRot;
// Make the main character face in the same direction as the camera
Vector3 camrot = m_camTransform.eulerAngles;
camrot.x = 0; camrot.z = 0;
m_transform.eulerAngles = camrot;
// Define 3 values to control movement
float xm = 0, ym = 0, zm = 0;
//Press W on the keyboard to move up
if (Input.GetKey(KeyCode.W))
{
zm += m_movSpeed * Time.deltaTime;
}
else if (Input.GetKey(KeyCode.S))//Press keyboard S to move down
{
zm -= m_movSpeed * Time.deltaTime;
}
if (Input.GetKey(KeyCode.A))//Press keyboard A to move left
{
xm -= m_movSpeed * Time.deltaTime;
}
else if (Input.GetKey(KeyCode.D))//Press keyboard D to move right
{
xm += m_movSpeed * Time.deltaTime;
}
if (Input.GetKey(KeyCode.Space) && m_transform.position.y <= 3)
{
ym+=m_movSpeed * Time.deltaTime;
}
if (Input.GetKey(KeyCode.F) && m_transform.position.y >= 1)
{
ym -= m_movSpeed * Time.deltaTime;
}
m_transform.Translate(new Vector3(xm,ym,zm),Space.Self);
}
}

How can I repeat this boost (push)?

I dont understand how I can make this shotgun jumps in my version of Unity: https://www.youtube.com/watch?v=FUkdz8jYt3w
How does this work?
Im using "First Person Controller" that looks like capsule
There are images: https://imgur.com/a/uvfAePX
This is for old version of Unity 4.5.5. I've tried RigidBody, but nothing happened. I've tried Transform, but again, no result.
First Person Controller:
using UnityEngine;
using System.Collections;
public class run : MonoBehaviour
{
public float speed = 6.0F;
public float jumpSpeed = 8.0F;
public float gravity = 20.0F;
private Vector3 moveDirection = Vector3.zero;
public Transform character;
public int CharacterForce = 5000;
public int time = 1;
void Update()
{
CharacterController controller =
GetComponent<CharacterController>();
if (controller.isGrounded)
{
moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis ("Vertical"));
moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= speed;
if (Input.GetButton("Jump"))
moveDirection.y = jumpSpeed;
}
moveDirection.y -= gravity * Time.deltaTime;
controller.Move (moveDirection * Time.deltaTime);
if (Input.GetMouseButtonDown(0))
{
Transform BulletInstance = (Transform)Instantiate(character, GameObject.Find("CameraRSP").transform.position, Quaternion.identity);
BulletInstance.GetComponent<Rigidbody>().AddForce(transform.forward * CharacterForce);
}
}
}
"Grenade" code:
using UnityEngine;
using System.Collections;
public class grenade : MonoBehaviour
{
public Transform GrenadeF;
public int force = 500;
public float radius;
void Start()
{
Collider[] col = Physics.OverlapSphere(transform.position, radius);
foreach (Collider c in col)
{
c.GetComponent<Rigidbody>().AddExplosionForce(force, transform.position, radius);
}
}
private void OnDrawGizmosSelected()
{
Gizmos.color = Color.blue;
Gizmos.DrawWireSphere(transform.position, radius);
}
}
When I used Transform I expected that this would work in ANY direction, but it worked in only one.
When I used RigidBody I expected that this would WORK, but my capsule didnt even moved.

Checkout the optional upwardsModifier parameter of
AddExplosionForce(float explosionForce, Vector3 explosionPosition, float explosionRadius, float upwardsModifier = 0.0f, ForceMode mode = ForceMode.Force));
(The API for Unity 4 is no longer available but I guess it should have been the same there)
Adjustment to the apparent position of the explosion to make it seem to lift objects.
and
Using this parameter, you can make the explosion appear to throw objects up into the air, which can give a more dramatic effect rather than a simple outward force. Force can be applied only to an active rigidbody.
By default it is 0 so if you don't pass it there won't be any upwards force.
As you can see in the example from the API
Vector3 explosionPos = transform.position;
Collider[] colliders = Physics.OverlapSphere(explosionPos, radius);
foreach (Collider hit in colliders)
{
Rigidbody rb = hit.GetComponent<Rigidbody>();
// |
// v
if (rb) rb.AddExplosionForce(power, explosionPos, radius, 3.0f);
}
they passed e.g. 3.0f as upwardsModifier. This makes the explosion
appear to be centred 3.0 units below its actual position for purposes of calculating the force direction (ie, the centre and the radius of effect are not modified).
Note: Typed on smartphone so no warrenty but I hope the idea gets clear

How Do I Shoot a Projectile into the Direction the Player is Facing?

I am creating a 2D side-scroller video game in Unity using c#. I have created the script that makes the player face the direction that the arrow key that was pressed was pointing to (when the right arrow is pressed, the player faces right. When the left arrow is pressed, the player faces left).
However, I cannot figure out how to make the harpoon that the player shoots point in the direction the player is facing. I have found many questions on Stack Overflow asking questions like this, but none of their answers worked for me.
Can anyone please tell me how to make the harpoon the player shoots face the direction the player is facing? Thanks in advance!
Here is my code that I use-
PLAYER SCRIPT
using UnityEngine;
using System.Collections;
public class playerMove : MonoBehaviour {
// All Variables
public float speed = 10;
private Rigidbody2D rigidBody2D;
private GameObject harpoon_00001;
private bool facingRight = true;
void Awake () {
rigidBody2D = GetComponent<Rigidbody2D>();
harpoon_00001 = GameObject.Find("harpoon_00001");
}
void Update () {
if (Input.GetKeyDown(KeyCode.LeftArrow) && !facingRight) {
Flip();
}
if (Input.GetKeyDown(KeyCode.RightArrow) && facingRight) {
Flip();
}
}
void Flip () {
facingRight = !facingRight;
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}
void FixedUpdate () {
float xMove = Input.GetAxis("Horizontal");
float yMove = Input.GetAxis("Vertical");
float xSpeed = xMove * speed;
float ySpeed = yMove * speed;
Vector2 newVelocity = new Vector2(xSpeed, ySpeed);
rigidBody2D.velocity = newVelocity;
if (Input.GetKeyDown("space")) {
GetComponent<AudioSource>().Play();
Instantiate(harpoon_00001,transform.position,transform.rotation);
}
}
}
HARPOON SCRIPT
using UnityEngine;
using System.Collections;
public class harpoonScript : MonoBehaviour {
// Public variable
public int speed = 6;
private Rigidbody2D r2d;
// Function called once when the bullet is created
void Start () {
// Get the rigidbody component
r2d = GetComponent<Rigidbody2D>();
// Make the bullet move upward
float ySpeed = 0;
float xSpeed = -8;
Vector2 newVelocity = new Vector2(xSpeed, ySpeed);
r2d.velocity = newVelocity;
}
void Update () {
if (Input.GetKeyDown(KeyCode.LeftArrow)) {
float xSpeed = -8;
}
if (Input.GetKeyDown(KeyCode.RightArrow)) {
float xSpeed = 8;
}
}
void OnTriggerEnter2D(Collider2D other) //hero hits side of enemy
{
Destroy(other.gameObject.GetComponent<Collider2D>()); //Remove collider to avoid audio replaying
other.gameObject.GetComponent<Renderer>().enabled = false; //Make object invisible
Destroy(other.gameObject, 0.626f); //Destroy object when audio is done playing, destroying it before will cause the audio to stop
}
}

You already defining a variable facingRight to know the direction of the the player. You can use that knowledge to control the harpoon.
For example:
// this line creates a new object, which has harpoonScript attached to it.
// In unity editor, you drag and drop this prefab(harpoon_00001) into right place.
// transform.position is used for the starting point of the fire. You can also add +-some_vector3 for better placement
// Quaternion.identity means no rotation.
harpoonScript harpoon = Instantiate(harpoon_00001,transform.position, Quaternion.identity) as harpoonScript;
// Assuming harpoon prefab already facing to right
if (!facingRight) {
// Maybe, not required
harpoon.transform.eulerAngles = new Vector3(0f, 0f, 180f); // Face backward
Vector3 theScale = harpoon.transform.localScale;
theScale.y *= -1;
harpoon.transform.localScale = theScale; // Flip on y axis
}

Unity 3D How to setup Turret Auto Aim? C#

what i't trying to achieve is have my turrent rotate and follow an "Enemy".
At the moment it detects the enemy but it is not rotating and I don't know why.
The bullet it a prefab i drag in, there has to be a better way to do this? Anyone have any suggestions please?
At the moment the bullet never triggers, but the log Shoot and does...and the rotate doesn't work.
Here is what i have
using UnityEngine;
using System.Collections;
public class TurretController : MonoBehaviour {
public Rigidbody bulletPrefab;
private Transform target;
private GameObject bullet;
private float nextFire;
private Quaternion targetPos;
void OnTriggerEnter(Collider otherCollider) {
if (otherCollider.CompareTag("Enemy"))
{
Debug.Log ("in");
target = otherCollider.transform;
StartCoroutine ("Fire");
}
}
void OnTriggerExit(Collider otherCollider) {
if (otherCollider.CompareTag("Enemy"))
{
Debug.Log ("out");
target = null;
StopCoroutine("Fire"); // aborts the currently running Fire() coroutine
}
}
IEnumerator Fire()
{
while (target != null)
{
nextFire = Time.time + 0.5f;
while (Time.time < nextFire)
{
// smooth the moving of the turret
targetPos = Quaternion.LookRotation (target.position);
transform.rotation = Quaternion.Slerp(transform.rotation, targetPos, Time.deltaTime * 5);
yield return new WaitForEndOfFrame();
}
// fire!
Debug.Log ("shoot");
bullet = Instantiate(bulletPrefab, transform.position, transform.rotation) as GameObject;
//bullet.rigidbody.velocity = transform.forward * bulletSpeed;
}
}
}
I tried to change the instantiate part by using this instead
bullet = (GameObject)Instantiate(bulletPrefab, transform.position, transform.rotation);
bullet.GetComponent<Bullet>().target = target.transform;
But then i just get errors like "InvalidCastException: Cannot cast from source type to destination type.
TurretController+c__Iterator0.MoveNext () (at Assets/Scripts/TurretController.cs:44)"

BTW, here's the turret rotation code I used in my project (shared with permission):
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class Turret : MonoBehaviour
{
[SerializeField]
private float turnRateRadians = 2 * Mathf.PI;
[SerializeField]
private Transform turretTop; // the gun part that rotates
[SerializeField]
private Transform bulletSpawnPoint;
private Enemy target;
void Update()
{
TargetEnemy();
}
void TargetEnemy()
{
if (target == null || target.health <= 0)
target = Enemy.GetClosestEnemy(turretTop, filter: enemy => enemy.health > 0);
if (target != null)
{
Vector3 targetDir = target.transform.position - transform.position;
// Rotating in 2D Plane...
targetDir.y = 0.0f;
targetDir = targetDir.normalized;
Vector3 currentDir = turretTop.forward;
currentDir = Vector3.RotateTowards(currentDir, targetDir, turnRateRadians*Time.deltaTime, 1.0f);
Quaternion qDir = new Quaternion();
qDir.SetLookRotation(currentDir, Vector3.up);
turretTop.rotation = qDir;
}
}
}
class Enemy : MonoBehaviour
{
public float health = 0;
private static HashSet<Enemy> allEnemies = new HashSet<Enemy>();
void Awake()
{
allEnemies.Add(this);
}
void OnDestroy()
{
allEnemies.Remove(this);
}
/// <summary>
/// Get the closest enemy to some transform, optionally filtering
/// (for example, enemies that aren't dead, or enemies of a certain type).
/// </summary>
public static Enemy GetClosestEnemy(Transform referenceTransform, System.Predicate<Enemy> filter=null)
{
// Left as an exercise for the reader.
// Remember not to use Vector3.Distance in a loop if you don't need it. ;-)
// return allEnemies[0];
}
}

First problem: the bullet prefab. The variable type is RigidBody. If you want to treat it as a game object, the variable must be a game object. Or you can instantiate it, cast to RigidBody, then use the .gameObject accessor. Like this:
((RigidBody)Instantiate(theRigidbody)).gameObject
Second problem: start simple with the rotation. If it's not working, don't get fancy yet. Start with something like this (an instant rotation toward the target):
Vector3 targetDirection = target.transform.position - transform.position;
targetDirection.y = 0; // optional: don't look up
transform.forward = targetDirection;
If it works, then add small pieces of additional complexity until it does exactly what you want. And if you don't get things figured out, give me a shout (a comment) on Monday. I've written turret-aiming code (including a maximum rotation speed), and I don't think my boss would mind if I upload it.
