Smooth lane change

Unity Engine
1

hi guys,

am trying to make my character moves lanes smoothly with out him teleporting i tried to element what i read on this post Rigidbody smooth lane transition - Questions & Answers - Unity Discussions, however i wast success full as it doesn’t move using the arrow keys however when i press the jump button it moves to the right hand side, any help or guide would be great

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
using System.Collections;

public class PlayerMovement : MonoBehaviour
{
    private bool gameStarted; // try and access this from the start script so when the player presses start the animation can start to run
    private float lane;
    private float runSpeed = 0.1f;
    private float jumpForce = 6;
    private bool OnGround;
    private bool isDead;
   
    Rigidbody myBody;
    Animator myAnim;

    private void Start()
    {
        lane = 0;
        myBody = GetComponent<Rigidbody>();
        myAnim = GetComponent<Animator>();
        OnGround = true;
        isDead = false;
    }

    private void Update()
    {
        // Lanes Movement

        if(Input.GetKeyDown(KeyCode.LeftArrow))
        {
            if(lane > -1)
            {
                lane -= 3.5f;
            }
        }

        if(Input.GetKeyDown(KeyCode.RightArrow))
        {
            if(lane < 1)
            {
                lane += 3.5f;
            }
        }

        Vector3 newPosition = myBody.position;
        newPosition.x = Mathf.MoveTowards(newPosition.x, lane, Time.deltaTime);
        myBody.position = newPosition;

        // Move Speed

        if(isDead == true)
        {
            myBody.AddForce(new Vector3(0, 0, 0));
        }
        else
        {
            myBody.MovePosition(transform.position + transform.forward * runSpeed);
        }

        // Jump Function

        if(OnGround)
        {
            if(Input.GetButtonDown("Jump"))
            {
                myAnim.SetBool("Jumping", true);
                Invoke("StopJumping",0.1f);
                myBody.velocity = new Vector3(jumpForce / 3, jumpForce, 0);
                OnGround = false;
            }

        }

        // sliding function

        if(Input.GetKeyDown(KeyCode.DownArrow) && OnGround == true)
        {
            myAnim.SetBool("Sliding", true);
            Invoke("StopSliding", 0.1f);
        }

    }

    private void OnCollisionEnter(Collision other)
    {
        if (other.gameObject.CompareTag("Ground"))
        {
            OnGround = true;

        }

        else if (other.gameObject.CompareTag("Death"))
        {
            isDead = true;
            myAnim.SetBool("Death", true);
            Invoke("StopDeath",0.1f);
        }
    }

    private void StopJumping()
    {
        myAnim.SetBool("Jumping", false);
    }

    private void StopSliding()
    {
        myAnim.SetBool("Sliding", false);
    }

    private void StopDeath()
    {
        myAnim.SetBool("Death", false);
    }
}

newPosition.x = Mathf.MoveTowards(newPosition.x, lane, Time.deltaTime);

This line is probably not what you want. The final parameter is a max change per frame. You need to give it a speed * Time.deltaTime. Or it will be changing just 1 per second.

Why in some places are you using MovePosition, but other places you’re setting the position directly? In some spots you’re setting velocity directly, in others you’re using AddForce? I can only assume you will get conflicting results.

This line:

 myBody.AddForce(new Vector3(0, 0, 0));

Will do nothing. You’re adding zero. If you want to stop all movement, here you would want to do velocity = Vector3.zero.

Otherwise you’ll probably want to be using AddForce(force, ForceMode.Impulse). Impulse is a one-frame force addition.

thank you very much it workes, sorry am just new to programming i hope one day i will be able to write things with out asking help :slight_smile:
