Player Tilt Problem

Questions & Answers
1

I am currently creating a endless runner game in Space where the character will tilt to the direction they are going to. For instance, if the player presses “a”, which moves the character to the left, the character will look tilt to the left a bit. When the player stopped pressing “a” the character tilts back to its original position.

This is my code that I have created for both movements and tilting

using UnityEngine;

public class Player_Movement : MonoBehaviour
{
    public Rigidbody rb;
    public float forwardForce = 2000f;
    public float sidewaysForce = 500f;
    public float upwardForce = 500f;
    public float downwardForce = 500f;
    public float tiltAmount = 15f; // Adjust the tilt amount as needed
    private bool isTiltingW = false;
    private bool isTiltingS = false;

    void FixedUpdate()
    {
        // Ensure Rigidbody's rotation is not frozen
        rb.freezeRotation = false;

        // Apply forward force
        rb.AddForce(transform.forward * forwardForce * Time.deltaTime);

        // Apply sideways force based on user input
        float horizontalInput = Input.GetAxis("Horizontal");
        float horizontalForce = horizontalInput * sidewaysForce * Time.deltaTime;
        rb.AddForce(transform.right * horizontalForce, ForceMode.VelocityChange);

        // Tilt the player based on its velocity when "a" or "d" is pressed
        if (isTiltingW)
        {
            float tilt = Mathf.Clamp(rb.velocity.y, -1f, 1f) * tiltAmount;
            transform.localRotation = Quaternion.Euler(-tilt, 0, 0);
        }
        else if (isTiltingS)
        {
            float tilt = Mathf.Clamp(rb.velocity.y, -1f, 1f) * tiltAmount;
            transform.localRotation = Quaternion.Euler(tilt, 0, 0);
        }
        else
        {
            // Smoothly return to the original rotation when not tilting
            transform.localRotation = Quaternion.Slerp(transform.localRotation, Quaternion.identity, Time.deltaTime);
        }
    }

    void Update()
    {
        // Detect if movement keys are pressed to enable tilt
        isTiltingW = Input.GetKey("w");
        isTiltingS = Input.GetKey("s");
    }
}

When I ran the scene, the character starts moving backwards and whenever I press “a” “d” “s” or “w” it just starts flying all over the place with the camera too, the camera follows the player where I placed the main camera as a child of the character in the hierarchy. All I want is for the camera to not move, when the character moves to the direction the button is pressed (a is left d is right w is up and s is down) the character is tilted to that direction.

There must be some error in the code or it could be an error in my unity scene. I will be grateful if someone can help me with this issue.

Make sure the player is “pointing” where you want it to go(ie the local forward axis or the blue one is pointing where the player should be going, you can check this by switching from “Global” to “Local” then clicking on the player )
Also transform.right and transform.forward depend upon the rotation of the object ie if the player is rotated(or tilting) then transform.right is going to change, you can fix this by using vector3.forward which doesn’t depend upon the rotation
