We Keep Coding

Unity need character to rotate to face movement direction on planetoid

we are working on a student project and we chose to do a Mario Galaxy style platformer with planetoids and gravity (kind of a big mistake for my first coding project but I cannot back out of it now) but I am having a hard time to get the character to face it's movement direction without absolutely spazzing out.
I have only been coding for around 2 months so please excuse me being useless at trying to figure this out.
This is the code I use for movement for the character
using System.Collections.Generic;
using UnityEngine;
public class SC_RigidbodyWalker : MonoBehaviour
{
public float speed = 5.0f;
public bool canJump = true;
public float jumpHeight = 2.0f;
public Camera playerCamera;
public float lookSpeed = 2.0f;
public float lookXLimit = 60.0f;
bool grounded = false;
Rigidbody r;
Vector2 rotation = Vector2.zero;
float maxVelocityChange = 10.0f;
void Awake()
{
r = GetComponent<Rigidbody>();
r.freezeRotation = true;
r.useGravity = false;
r.collisionDetectionMode = CollisionDetectionMode.ContinuousDynamic;
rotation.y = transform.eulerAngles.y;
Cursor.lockState = CursorLockMode.Locked;
Cursor.visible = false;
}
void Update()
{
}
void FixedUpdate()
{
if (grounded)
{
// Calculate how fast we should be moving
Vector3 forwardDir = Vector3.Cross(transform.up, -playerCamera.transform.right).normalized;
Vector3 rightDir = Vector3.Cross(transform.up, playerCamera.transform.forward).normalized;
Vector3 targetVelocity = (forwardDir * Input.GetAxis("Vertical") + rightDir * Input.GetAxis("Horizontal")) * speed;
Vector3 velocity = transform.InverseTransformDirection(r.velocity);
velocity.y = 0;
velocity = transform.TransformDirection(velocity);
Vector3 velocityChange = transform.InverseTransformDirection(targetVelocity - velocity);
velocityChange.x = Mathf.Clamp(velocityChange.x, -maxVelocityChange, maxVelocityChange);
velocityChange.z = Mathf.Clamp(velocityChange.z, -maxVelocityChange, maxVelocityChange);
velocityChange.y = 0;
velocityChange = transform.TransformDirection(velocityChange);
r.AddForce(velocityChange, ForceMode.VelocityChange);
if (Input.GetButton("Jump") && canJump)
{
r.AddForce(transform.up * jumpHeight, ForceMode.VelocityChange);
}
}
grounded = false;
}
void OnCollisionStay()
{
grounded = true;
}
}
And here are the code for the gravity functions
using System.Collections.Generic;
using UnityEngine;
public class SC_PlanetGravity : MonoBehaviour
{
public Transform planet;
public bool alignToPlanet = true;
float gravityConstant = 9.8f;
Rigidbody r;
void Start()
{
r = GetComponent<Rigidbody>();
}
void FixedUpdate()
{
Vector3 toCenter = planet.position - transform.position;
toCenter.Normalize();
r.AddForce(toCenter * gravityConstant, ForceMode.Acceleration);
if (alignToPlanet)
{
Quaternion q = Quaternion.FromToRotation(transform.up, -toCenter);
q = q * transform.rotation;
transform.rotation = Quaternion.Slerp(transform.rotation, q, 1);
}
}
}

I can propose an alternative approach which I believe will simplify the problem, should you choose. If the root of your character is positioned at the center of the planetoid, then all movement can be handled as a rotation on root and you won't be fighting the inertia of the character or needing to orient it to the planetoid. Jumping could be handled by adding another child below the root that can slide up and down. Hope this helps!

I managed to get it working by having a new script added to the player avatar.
Here is the code, it's basically a copy paste of a part of the RigidBodyWalker script with some more added parts. It's not perfect but it works like I wanted it to.
using System.Collections.Generic;
using UnityEngine;
public class InputRotation : MonoBehaviour
{
public Camera playerCamera;
public float speed;
public float rotationSpeed;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
//float horizontalInput = Input.GetAxis("Horizontal");
//float verticalInput = Input.GetAxis("Vertical");
}
private void FixedUpdate()
{
Vector3 forwardDir = Vector3.Cross(transform.up, -playerCamera.transform.right).normalized;
Vector3 rightDir = Vector3.Cross(transform.up, playerCamera.transform.forward).normalized;
Vector3 targetVelocity = (forwardDir * Input.GetAxis("Vertical") + rightDir * Input.GetAxis("Horizontal")) * speed;
if(targetVelocity != Vector3.zero)
{
Quaternion toRotation = Quaternion.LookRotation(targetVelocity, transform.up);
transform.rotation = Quaternion.RotateTowards(transform.rotation, toRotation, rotationSpeed * Time.deltaTime);
}
}
}

Diagonal movements are faster than normal movements

FIRST : SORRY FOR MY ENGLISH !!!
Hello everyone, i'm very new into Unity (5 days).
Today i've make a script for the basics movements with a rigid-bodie, BUT the diagonal movements are faster than the normal movements.. I search on Internet but I don't find a post that i can understand.
So here my script.
Also if you know how to not move when we jump, or when we jump into a direction, it follow this direction, tell me. (I know my english is terrible.) Also, i'm new into this website.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovements : MonoBehaviour
{
[SerializeField] private float walkingSpeed;
[SerializeField] private float runningSpeed;
[SerializeField] private float jumpForce;
[SerializeField] private float jumpRaycastDistance;
private Rigidbody rb;
float speed;
Vector3 movement;
/////////////////////////////////////////////////////
void Start()
{
rb = GetComponent<Rigidbody>();
}
/////////////////////////////////////////////////////
void Update()
{
Jumping();
}
/////////////////////////////////////////////////////
private void FixedUpdate()
{
Movements();
}
/////////////////////////////////////////////////////
private void Movements()
{
float hAxis = Input.GetAxisRaw("Horizontal");
float vAxis = Input.GetAxisRaw("Vertical");
if(Input.GetButton("Run"))
{
Vector3 movement = new Vector3(hAxis, 0, vAxis) * runningSpeed * Time.deltaTime;
Vector3 newPosition = rb.position + rb.transform.TransformDirection(movement);
rb.MovePosition(newPosition);
}
else
{
Vector3 movement = new Vector3(hAxis, 0, vAxis) * walkingSpeed * Time.deltaTime;
Vector3 newPosition = rb.position + rb.transform.TransformDirection(movement);
rb.MovePosition(newPosition);
}
}
/////////////////////////////////////////////////////
private void Jumping()
{
if(Input.GetButtonDown("Jump"))
{
if (isGrounded())
{
rb.AddForce(0, jumpForce, 0, ForceMode.Impulse);
}
}
}
/////////////////////////////////////////////////////
private bool isGrounded()
{
return Physics.Raycast(transform.position, Vector3.down, jumpRaycastDistance);
}
}

You need to clamp your velocity in order to keep it same. Look into Vector3.ClampMagnitude()
velocity = Vector3.ClampMagnitude(velocity, _movementSpeed);
velocity.y = playerVelocity.Y; // keeping your Y velocity same since you have jumping.
playerVelocity = velocity;
EDIT: in your case it should be something like this.
_maxSpeed is the speed limit.
private void FixedUpdate()
{
Movements();
var clampedVelocity = Vector3.ClampMagnitude(rb.velocity, _maxSpeed);
clampedVelocity.y = rb.velocity.y;
rb.velocity = clampedVelocity;
}

Try normalizing the vector. (more info is on unity docs, but normalize() will make sure that the sum of all the vector's values isnt above 1.

How to let camera's vertical rotation move the camera up and down?

I have a player in the game, which I can move using the keyboard and rotate only on the horizontal axis using the mouse. That means, I can aim only horizontally and I can not aim it up and down.
I have the Main Camera and another VM Camera from Cinemachine. The current state of the game is like this:
On the horizontal axis, I rotate the player, but on the vertical axis I only want the player's camera/FOV to be moved up and down.
My movement script attached to the player is:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public CharacterController characterController;
public float speed = 35f;
public Animator animator;
// camera and rotation
public Transform cameraHolder;
public float mouseSensitivity = 2f;
public float upLimit = 50;
public float downLimit = -50;
// gravity
private float gravity = 9.87f;
private float verticalSpeed = 0;
void Update()
{
Move();
Rotate();
}
public void Rotate()
{
float horizontalRotation = Input.GetAxis("Mouse X");
float verticalRotation = Input.GetAxis("Mouse Y");
transform.Rotate(0, horizontalRotation * mouseSensitivity, 0);
cameraHolder.Rotate(-verticalRotation * mouseSensitivity, 0, 0);
Vector3 currentRotation = cameraHolder.localEulerAngles;
if (currentRotation.x > 180) currentRotation.x -= 360;
currentRotation.x = Mathf.Clamp(currentRotation.x, upLimit, downLimit);
cameraHolder.localRotation = Quaternion.Euler(currentRotation);
}
private void Move()
{
float horizontalMove = Input.GetAxis("Horizontal");
float verticalMove = Input.GetAxis("Vertical");
if (characterController.isGrounded) verticalSpeed = 0;
else verticalSpeed -= gravity * Time.deltaTime;
Vector3 gravityMove = new Vector3(0, verticalSpeed, 0);
Vector3 move = transform.forward * verticalMove + transform.right * horizontalMove;
characterController.Move(speed * Time.deltaTime * move + gravityMove * Time.deltaTime);
}
}

This is the code i use, it works for me, it's super easy to implement, and stops moving the camera when you aren't focusing the game, is the script from one of Brackey's tutorials modified for this purpose:
using UnityEngine;
public class CameraController : MonoBehaviour
{
public PlayerController player;
public float sensitivity = 150f;
public float clampAngle = 85f;
public bool look = true;
private float verticalRotation;
private float horizontalRotation;
private void Start()
{
verticalRotation = transform.localEulerAngles.x;
horizontalRotation = player.transform.eulerAngles.y;
// Defines the state of the cursor
Cursor.lockState = CursorLockMode.Locked;
Cursor.visible = false;
}
private void Update()
{
// Looks around if the user is in the window
if (look)
{
Look();
}
Debug.DrawRay(transform.position, transform.forward * 2, Color.red);
// If the player presses ESC while in the game, it unlocks the cursor
if (look && Input.GetKeyDown(KeyCode.Escape))
{
look = false;
Cursor.lockState = CursorLockMode.None;
Cursor.visible = true;
}
else if (Input.GetMouseButtonDown(0) && !look)
{
look = true;
Cursor.lockState = CursorLockMode.Locked;
Cursor.visible = false;
}
}
private void Look()
{
float _mouseVertical = -Input.GetAxis("Mouse Y");
float _mouseHorizontal = Input.GetAxis("Mouse X");
verticalRotation += _mouseVertical * sensitivity * Time.deltaTime;
horizontalRotation += _mouseHorizontal * sensitivity * Time.deltaTime;
verticalRotation = Mathf.Clamp(verticalRotation, -clampAngle, clampAngle);
transform.localRotation = Quaternion.Euler(verticalRotation, 0f, 0f);
player.transform.rotation = Quaternion.Euler(0f, horizontalRotation, 0f);
}
}

Player gravity turns off while i move in Unity

I am quite new to unity and I have two scripts, one for gravity and one for player movement as the names suggest. The reason I am using a gravity script is that the third person movement doesn't support using a rigidbody with position and rotation enabled, so I have frozen the position and the rotation inside the rigidbody (which turns off gravity in the rigidbody). I made the Gravity script myself but I followed a tutorial on the player movement script because I have no idea how to make third person movement so I don't really know what is going on in the movement script.
Movement script:
public class ThirdPersonMovement : MonoBehaviour
{
public CharacterController controller;
public Transform cam;
public float speed = 6f;
public float turnSmoothTime = 0.1f;
float turnSmoothVelocity;
void Update()
{
float horizontal = Input.GetAxisRaw("Horizontal");
float vertical = Input.GetAxisRaw("Vertical");
UnityEngine.Vector3 direction = new UnityEngine.Vector3(horizontal, 0f, vertical).normalized;
if (direction.magnitude >= 0.1f)
{
float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y;
float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
transform.rotation = UnityEngine.Quaternion.Euler(0f, angle, 0f);
UnityEngine.Vector3 moveDir = UnityEngine.Quaternion.Euler(0f, targetAngle, 0f) * UnityEngine.Vector3.forward;
controller.Move(moveDir.normalized * speed * Time.deltaTime);
}
}
}
Gravity script:
public class gravityScript : MonoBehaviour
{
public float GravitySpeed = -0.03f;
public bool GravityCheck = false;
void OnCollisionEnter(Collision col)
{
if (col.gameObject.name == "Terrain0_0")
{
GravityCheck = true;
}
}
void OnCollisionExit(Collision col)
{
GravityCheck = false;
}
void Update()
{
if (GravityCheck == false)
{
transform.Translate(0, GravitySpeed, 0);
}
}
}
Thank you in advance :)

I don't know what happened but when I opened it today (the day after posting) it was working fine. It was likely just a bug that got fixed after a restart.

Unity Raycasting problem in some part of the scene

I started doing some simple stuff in Unity (goal is to make a great game) so I made a simple Player Controller.
public class PlayerController : MonoBehaviour
{
public float walkingSpeed;
public float jumpSpeed;
public bool jumpFlag = false;
public float maxJumpDistance = 1.0f;
Rigidbody rb;
Collider col;
Vector3 playerSize;
// Start is called before the first frame update
void Start()
{
rb = GetComponent<Rigidbody>();
col = GetComponent<Collider>();
playerSize = col.bounds.size;
}
// Update is called once per frame
void FixedUpdate()
{
WalkHandler();
JumpHandler();
}
void WalkHandler()
{
float horizonstalAxis = Input.GetAxis("Horizontal");
float verticalAxis = Input.GetAxis("Vertical");
Vector3 movement = new Vector3(-horizonstalAxis * walkingSpeed * Time.deltaTime, 0, -verticalAxis * walkingSpeed * Time.deltaTime);
rb.MovePosition(transform.position += movement);
}
void JumpHandler()
{
float jumpAxis = Input.GetAxis("Jump");
//Debug.Log(jumpAxis);
if (jumpAxis > 0)
{
bool isGrounded = CheckGrounded();
if (jumpFlag != true && isGrounded)
{
jumpFlag = true;
Vector3 jumpVector = new Vector3(0, jumpSpeed * Time.deltaTime, 0);
rb.AddForce(jumpVector, ForceMode.VelocityChange);
}
}
else
{
jumpFlag = false;
}
}
bool CheckGrounded()
{
Vector3 checkerPoint = transform.position + new Vector3(0, -playerSize.y / 2, 0);
bool grounded = Physics.Raycast(checkerPoint, -Vector3.up, maxJumpDistance);
return grounded;
}
I came across a wierd problem. In some parts of the scene my method JumpHandler is not working. After reaching some z coordinates, the CheckGrounded returns False instead of True, even though the Raycast direction is set down.
Can anyone help?
