The object is not moving down the slope i have also tried to reduce the friction to zero but not working and i am using a ball as my object
how to move an object in unity in 2d
Here is my code:
public class move : MonoBehaviour
{
public float moveSpeed = 3f;
Rigidbody2D rig;
float yat ;
void Start()
{
rig = GetComponent<Rigidbody2D>();
}
void Update()
{
float xat = Input.GetAxis("Horizontal");
yat = rig.velocity.y;
rig.velocity = new Vector2(xat*moveSpeed,yat);
}
}
My apologize i don't get it exactly what you try to do? But if you simply moving the object you can try "Transfrom.Translate" method.
By the way, using velocity method try this code in your own version :
float speed = 0.5f;
...
void Update () {
float inputHorizontal = Input.GetAxisRaw("Horizontal");
player.velocity = Vector2.right * inputHorizontal * speed;
}
Imo this should work, if you have any other query let me know.

I am trying to make a first-person game in Unity but I keep having issues with my character controller. The player keeps rotating when it collides with objects that have physics (Or rigidbody)
It doesn't rotate when it collides with objects that don't have physics.
It's not my mouse because my MouseX and Y Values aren't changing.
Here is the code for the Player
using System.Collections.Generic;
using UnityEngine;
using Unity.Netcode;
public class PlayerControllerRB : MonoBehaviour
{
public float speed = 10f;
public float jumpHeight = 4.65f;
[SerializeField] private Rigidbody rb;
private PlayerInput playerInput;
private PlayerInput.OnFootActions onFoot;
[SerializeField] private Camera cam;
public float xSensitivity = 8f;
public float ySensitivity = 8f;
private float xRotation;
private float yMovement;
private float hMovement;
[SerializeField] private Transform Feet;
[SerializeField] public LayerMask Ground;
private void Awake()
{
rb = GetComponent<Rigidbody>();
playerInput = new PlayerInput();
onFoot = playerInput.onFoot;
onFoot.Jump.performed += ctx => Jump();
}
private void Start()
{
Cursor.lockState = CursorLockMode.Locked;
Cursor.visible = false;
}
#region
private void OnEnable()
{
playerInput.Enable();
onFoot.Enable();
}
private void OnDisable()
{
playerInput.Disable();
onFoot.Disable();
}
#endregion
private void FixedUpdate()
{
ProcessMove(onFoot.Movement.ReadValue<Vector2>());
}
private void Update()
{
ProcessLook(onFoot.Look.ReadValue<Vector2>());
}
void ProcessMove(Vector2 input)
{
Vector3 MoveDirection = Vector3.zero;
hMovement = input.x;
yMovement = input.y;
MoveDirection = transform.forward * yMovement + transform.right * hMovement;
//MoveDirection.y = rb.velocity.y;
Debug.Log(MoveDirection * speed);
rb.AddForce(MoveDirection * speed, ForceMode.Acceleration);
}
void Jump()
{
Ray ray = new Ray(Feet.position, Vector3.down);
RaycastHit info;
if(Physics.Raycast(ray, out info, 0.3f, Ground))
{
rb.AddForce(Vector3.up * jumpHeight, ForceMode.Impulse);
}
}
void ProcessLook(Vector2 input)
{
float MouseY = input.y;
float MouseX = input.x;
xRotation -= (MouseY * Time.deltaTime) * ySensitivity;
xRotation = Mathf.Clamp(xRotation, -80f, 80f);
cam.transform.localRotation = Quaternion.Euler(xRotation, 0, 0);
transform.Rotate(Vector3.up * (MouseX * Time.deltaTime) * xSensitivity);
}
}
I tried freezing the y rotation but then I get a jittry camera.
Can anyone help me? It would also be nice if you had any recommendations to improve the controller.
Please comment if you need any more information. Sorry if the post is junk, I'm new to Stackoverflow
Well, you said It doesn't rotate when it collides with objects that don't have physics. In order to use the colliders one of them has to have a rigibody component. So if that's the case maybe is the script that is inside the oncollisionenter causing the problems. But I don't see any oncollisionenter script here
i have been recreating my jump code, i have it all done but i can't add force or anything else.
Here's my code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class pBeh : MonoBehaviour
{
CharacterController characterController;
public float MovementSpeed = 1;
public float Gravity = 9.8f;
private float velocity = 0;
private Camera mainCam;
public Rigidbody rb;
public float jumpSpeed = 5.2f;
private Vector3 movingDirection = Vector3.zero;
public CharacterController controller;
public float speed;
float turnSmoothVelocity;
public float turnSmoothTime;
public bool canJump = false;
private void Start()
{
characterController = GetComponent<CharacterController>();
mainCam = Camera.main;
}
void Update()
{
// player movement - forward, backward, left, right
float horizontal = Input.GetAxis("Horizontal") * 10;
float vertical = Input.GetAxis("Vertical") * 10;
Vector3 camRightFlat = new Vector3(mainCam.transform.right.x, 0,
mainCam.transform.right.z).normalized;
Vector3 camForwardFlat = new Vector3(mainCam.transform.forward.x, 0,
mainCam.transform.forward.z).normalized;
characterController.Move((camRightFlat * horizontal + camForwardFlat * vertical)
* Time.deltaTime);
// Gravity
if (characterController.isGrounded)
{
velocity = 0;
}
else
{
velocity -= Gravity * Time.deltaTime;
characterController.Move(new Vector3(0, velocity, 0));
}
if (canJump == true && Input.GetKeyDown(KeyCode.Space))
{
Debug.Log("Jumped");/*
transform.Translate(Vector3.up * 5.0f * Time.deltaTime);
rb.AddRelativeForce(Vector3.up * 8.0f);
rb.AddForce(Vector3.up * 8.0f)
i have tried a lot more, but it just doesn't work.
The sphere (Player) does nothing or shakes.
*/
}
}
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.tag == "enemy")
{
SceneManager.LoadScene("SampleScene");
}
}
void FixedUpdate()
{
if ((controller.collisionFlags & CollisionFlags.Below) != 0)
{
//Debug.Log("ground");
canJump = true;
}
else
{
canJump = false;
}
}
As i said it works just fine i just can't find reason why i cannot jump.
I have all character controller right and rigidbody too. If you could help i would be happy.
Btw i am beginner so i copied movement to be same as camera. Thanks!
From what I know, rigidbody and character controller do not work together (on the same object) so you have to choose one or the other, if you are using rigidbody then a ground check or similiar stuff would not be necessary since rigidbody is using unity physicis system so a lot of the stuff would be already done for you to simulate physics but you should still read thru the document
I'm creating a game in Unity3D that contains a planet in a scene. I want the camera to move around the planet and rotate in the vector direction of the mouse when the player is holding down the right click anywhere on the screen. I have code written out as seen below. The code works great, however the player is only able to rotate the camera around the planet if the mouse is on the planet and not off the planet. How do I change it so that the camera will rotate around the planet even if the mouse is not on the planet?
public class CameraHumanMovement : MonoBehaviour
{
[Header("Settings")]
public float planetRadius = 100f;
public float distance;
public GameObject planet;
public Transform camTransform;
public Transform holderTransform;
private Vector3? mouseStartPosition1;
private Vector3? currentMousePosition1;
public bool dog;
private void LateUpdate()
{
if (Input.GetMouseButtonDown(1))
mouseStartPosition = GetMouseHit();
if (mouseStartPosition != null)
DragPlanet();
if (Input.GetMouseButtonUp(1))
StaticPlanet();
}
private void DragPlanet()
{
currentMousePosition1 = GetMouseHit();
RotateCamera((Vector3)mouseStartPosition1, (Vector3)currentMousePosition1);
}
private void StaticPlanet()
{
mouseStartPosition1 = null;
currentMousePosition1 = null;
}
private void RotateCamera(Vector3 dragStartPosition, Vector3 dragEndPosition)
{
//normalised for odd edges
dragEndPosition = dragEndPosition.normalized * planetRadius;
dragStartPosition = dragStartPosition.normalized * planetRadius;
// Cross Product
Vector3 cross = Vector3.Cross(dragEndPosition, dragStartPosition);
// Angle for rotation
float angle = Vector3.SignedAngle(dragEndPosition, dragStartPosition, cross);
//Causes Rotation of angle around the vector from Cross product
holderTransform.RotateAround(planet.transform.position, cross, angle);
}
private static Vector3? GetMouseHit()
{
RaycastHit hit;
if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hit))
{
return hit.point;
}
return null;
}
}
A simple code could be like this :
public class CameraHumanMovement : MonoBehaviour
{
//Rotation speed exposed on the inspector
public float RotationSpeed = 10f;
private void Update()
{
//Whenever the left mouse button is pressed rotate this object that holds this script in the x and y axis.
//You can reference your planet and put this script in another object if you want and it will be "yourplanetobject.transform etc.."
if(Input.GetMouseButton(0))
{
float rotX = Input.GetAxis("Mouse X") * RotationSpeed * Time.deltaTime;
float rotY = Input.GetAxis("Mouse Y") * RotationSpeed * Time.deltaTime;
transform.Rotate(Vector3.up, -rotX);
transform.Rotate(Vector3.right, rotY);
}
}
}
Cheers!
I am making a 2d top down game where the player can rotate the camera around himself as he moves through the world.
Everything works fine when the player is moving around the world the camera follows him fine. if he standing still then the camera rotation also works very well. However as soon as I start to do both then there is a jittery in the camera that makes all other objects jitter besides the player.
Now in working with this problem I have found out that this could have to do with the fact that I use rigidbody2d.AddRelativeForce (so physics) to move the player and that his movements are checked in FixedUpdate.
https://forum.unity3d.com/threads/camera-jitter-problem.115224/ http://answers.unity3d.com/questions/381317/camera-rotation-jitterness-lookat.html
I have tried moving my camera rotation and the following scripts to LateUpdate, FixedUpdate, Update you name it. Nothing seems to work. I am sure that there is some sort of delay between movement of the camera and the rotation that is causing this. I am wondering if anyone has any feedback?
I have tried disabling Vsync, does not remove it entirely
I have tried interpolating and extrapolating the rigidbody and although there is a difference it does not remove it entirely. Ironically it seemd if I have it set to none, it works best.
Scripts:
To Follow character, script applied to a gameobject that has the camera as a child
public class FollowPlayer : MonoBehaviour {
public Transform lookAt;
public Spawner spawner;
private Transform trans;
public float cameraRot = 3;
private bool smooth = false;
private float smoothSpeed = 30f;
private Vector3 offset = new Vector3(0, 0, -6.5f);
//test
public bool changeUpdate;
private void Start()
{
trans = GetComponent<Transform>();
}
private void FixedUpdate()
{
CameraRotation();
}
private void LateUpdate()
{
following();
}
public void following()
{
Vector3 desiredPosition = lookAt.transform.position + offset;
if (smooth)
{
transform.position = Vector3.Lerp(transform.position, desiredPosition, smoothSpeed);
}
else
{
transform.position = desiredPosition;
}
}
void CameraRotation()
{
if (Input.GetKey("q"))
{
transform.Rotate(0, 0, cameraRot);
}
if (Input.GetKey("e"))
{
transform.Rotate(0, 0, -cameraRot);
}
}
public void SetTarget(string e)
{
lookAt = GameObject.Find(e).GetComponent<Transform>();
}
}
The character Controller, script applied to the Player, is called in FixedUpdate
private void HandleMovement()
{
if (Input.GetKey("w"))
{
rigid.AddRelativeForce(Vector2.up * speed);
}
if (Input.GetKey("s"))
{
rigid.AddRelativeForce(Vector2.down * speed);
}
if (Input.GetKey("a"))
{
if (facingRight)
{
Flip();
}
rigid.AddRelativeForce(Vector2.left * speed);
}
if (Input.GetKey("d"))
{
if (!facingRight)
{
Flip();
}
rigid.AddRelativeForce(new Vector2(1,0) * speed);
}
}
Try to use Coroutines. I modified some of my scripts to be more familiar to Your code, tried it, and I didn't see any jittery. I hope that will help You.
Camera Class:
public class CameraController : MonoBehaviour {
[SerializeField]
Transform CameraRotator, Player;
[SerializeField]
float rotationSpeed = 10f;
float rotation;
bool rotating = true;
void Start()
{
StartCoroutine(RotatingCamera());
}
IEnumerator RotatingCamera()
{
while (rotating)
{
rotation = Input.GetAxis("HorizontalRotation");
CameraRotator.Rotate(Vector3.up * Time.deltaTime * rotation * rotationSpeed);
CameraRotator.position = Player.position;
yield return new WaitForFixedUpdate();
}
}
private void OnDestroy()
{
StopAllCoroutines();
}
}
Player Class:
public class PlayerMovement : MonoBehaviour {
[SerializeField]
float movementSpeed = 500f;
Vector3 movementVector;
Vector3 forward;
Vector3 right;
[SerializeField]
Transform CameraRotator;
Rigidbody playerRigidbody;
float inputHorizontal, inputVertical;
void Awake()
{
playerRigidbody = GetComponent<Rigidbody>();
StartCoroutine(Moving());
}
IEnumerator Moving()
{
while (true)
{
inputHorizontal = Input.GetAxis("Horizontal");
inputVertical = Input.GetAxis("Vertical");
forward = CameraRotator.TransformDirection(Vector3.forward);
forward.y = 0;
forward = forward.normalized;
Vector3 right = new Vector3(forward.z, 0, -forward.x);
movementVector = inputHorizontal * right + inputVertical * forward;
movementVector = movementVector.normalized * movementSpeed * Time.deltaTime;
playerRigidbody.AddForce(movementVector);
yield return new WaitForFixedUpdate();
}
}
}
I fixed this problem finally:
First I made my cameraRotation() and follow() into 1 function and gave it a better clearer name:
public void UpdateCameraPosition()
{
if (Input.GetKey("q"))
{
transform.Rotate(0, 0, cameraRot);
}
else if (Input.GetKey("e"))
{
transform.Rotate(0, 0, -cameraRot);
}
Vector3 desiredPosition = lookAt.transform.position + offset;
transform.position = desiredPosition;
}
I then called that function from the character controller straight after the handling of movement. Both calls (handleMovement & cameraPosition) in fixedUpdate.
void FixedUpdate()
{
HandleMovement();
cameraController.UpdateCameraPosition();
}
and the jittering was gone.
So it seems it was imply because there was a slight delay between the two calls as the previous posts I read had said. But I had failed to be able to properly Set them close enough together.
Hope this helps someone.
I have tried checking the documentation and it seems correct to me but still I'm getting an error when i try to build this project.
using UnityEngine;
using System.Collections;
public class PlayerController : MonoBehaviour {
private Rigidbody rb;
void Start () {
rb = GetComponent<Rigidbody> ();
}
void FixedUpdate () {
Input side = Input.GetAxis("Horizontal");
Input up = Input.GetAxis("Vertical");
Vector3 movement = new Vector3 (side, 0.0f, up);
rb.AddForce (movement);
}
}
Your mistakes are on these two lines:
Input side = Input.GetAxis("Horizontal");
Input up = Input.GetAxis("Vertical");
Input.GetAxis returns float but you are assigning that to Input which is not a float and does not even exist. So, replace Input side and Input up with float side and float up.
public class PlayerController : MonoBehaviour {
// Use this for initialization
private Rigidbody rb;
void Start()
{
rb = GetComponent<Rigidbody>();
}
// Update is called once per frame
void FixedUpdate()
{
float side = Input.GetAxis("Horizontal");
float up = Input.GetAxis("Vertical");
Vector3 movement = new Vector3(side, 0.0f, up);
rb.AddForce(movement);
}
}
