When jumping, the rotation value becomes 0 - unity3d

Question

this is my PlayerMovement script.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public CharacterController controller;
public float turnSmoothTime = 0.1f;
float turnSmoothVelocity;
public float Speed = 10f;
private Vector3 moveDirection;
public float groundDistance = 0.4f;
public float gravity = -9.81f;
public float jumpPower = 3.5f;
public float directionY;
bool isGrounded;
public Animator anim;
public Transform cam;
private void Update()
{
float horizontal = Input.GetAxisRaw("Horizontal");
float vertical = Input.GetAxisRaw("Vertical");
moveDirection = new Vector3(horizontal, 0f, vertical).normalized;
if (controller.isGrounded)
{
if (Input.GetKeyDown(KeyCode.Space))
{
directionY = jumpPower;
}
else
{
directionY = 0;
}
}
if (!controller.isGrounded)
{
directionY += gravity * Time.deltaTime;
}
moveDirection.y = directionY;
if (moveDirection.magnitude >= 0.1f)
{
float targetAngle = Mathf.Atan2(moveDirection.x, moveDirection.z) * Mathf.Rad2Deg;
float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
transform.rotation = Quaternion.Euler(0f, angle, 0f);
controller.Move(moveDirection * Speed * Time.deltaTime);
}
bool hasHorizontalInput = !Mathf.Approximately(horizontal, 0f);
bool hasVerticalInput = !Mathf.Approximately(vertical, 0f);
bool isWalking = hasHorizontalInput || hasVerticalInput;
}
}
I want to make smooth jump system using by characterController.
My code works fine in the ground state, but when I press space(for jump), it returns the current rotation y value to 0.
(I think this problem is because the jump's position value is y, but the movement's rotation value is also y.)
how do i solve it? I want the rotation value not to change even if I jump.

Answer 1

I solved.
It was a code execution order issue.
float horizontal = Input.GetAxisRaw("Horizontal");
float vertical = Input.GetAxisRaw("Vertical");
Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;
if (controller.isGrounded && Input.GetButton("Jump"))
{
movingDirection.y = jumpSpeed;
}
movingDirection.y -= gravity * Time.deltaTime;
controller.Move(movingDirection * Time.deltaTime * speed);
if (direction.magnitude >= 0.1f)
{
float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg;
float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
transform.rotation = Quaternion.Euler(0f, angle, 0f);
controller.Move(direction * speed * Time.deltaTime);
}
