how to make a player movement script in unity code example

Example 1: movement script c#

using UnityEngine;
using System.Collections;

// This script moves the character controller forward
// and sideways based on the arrow keys.
// It also jumps when pressing space.
// Make sure to attach a character controller to the same game object.
// It is recommended that you make only one call to Move or SimpleMove per frame.

public class ExampleClass : MonoBehaviour
{
    CharacterController characterController;

    public float speed = 6.0f;
    public float jumpSpeed = 8.0f;
    public float gravity = 20.0f;

    private Vector3 moveDirection = Vector3.zero;

    void Start()
    {
        characterController = GetComponent<CharacterController>();
    }

    void Update()
    {
        if (characterController.isGrounded)
        {
            // We are grounded, so recalculate
            // move direction directly from axes

            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0.0f, Input.GetAxis("Vertical"));
            moveDirection *= speed;

            if (Input.GetButton("Jump"))
            {
                moveDirection.y = jumpSpeed;
            }
        }

        // Apply gravity. Gravity is multiplied by deltaTime twice (once here, and once below
        // when the moveDirection is multiplied by deltaTime). This is because gravity should be applied
        // as an acceleration (ms^-2)
        moveDirection.y -= gravity * Time.deltaTime;

        // Move the controller
        characterController.Move(moveDirection * Time.deltaTime);
    }
}

Example 2: movement script unity

//make sure to add a CharacterController to the thing that you want to move
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    CharacterController characterController;

    public float jumpSpeed = 8.0f;
    public float gravity = 20.0f;
    public float speed = 9.0f;

    private Vector3 moveDirection = Vector3.zero;

    private void Start()
    {
        characterController = GetComponent<CharacterController>();
    }

    void Update()
    {
        var horizontal = Input.GetAxis("Horizontal");
        var vertical = Input.GetAxis("Vertical");

        transform.Translate(new Vector3(horizontal, 0, vertical) * (speed * Time.deltaTime));

        if (characterController.isGrounded)
        {

            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0.0f, Input.GetAxis("Vertical"));
            moveDirection *= speed;

            if (Input.GetButton("Jump"))
            {
                moveDirection.y = jumpSpeed;
            }
        }
        moveDirection.y -= gravity * Time.deltaTime;
        characterController.Move(moveDirection * Time.deltaTime);
    }
}

Example 3: how to add movement in unity

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    private string moveInputAxis = "Vertical";
    

    public float moveSpeed = 0.1f;
    public Rigidbody rb;
    public bool cubeIsOnTheGround = true;


    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }
    
    // Update is called once per frame
    void Update()
    {
       float moveAxis = Input.GetAxis(moveInputAxis); 

       ApplyInput(moveAxis);

       if(Input.GetButtonDown("Jump") && cubeIsOnTheGround == true)
       {
           rb.AddForce(new Vector3(0, 7, 0), ForceMode.Impulse);
           cubeIsOnTheGround = false;
       } 

    private void ApplyInput(float moveInput)
    {
        Move(moveInput);
    }

    private void Move(float input)
    {
        transform.Translate(Vector3.forward * input * moveSpeed);
    }    

    private void OnCollisionEnter(Collision collision) {
        if(collision.gameObject.tag == "Ground") {
            cubeIsOnTheGround = true;
        }
    }
}

Example 4: unity player movement script

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Example : MonoBehaviour
{
    private CharacterController controller;
    private Vector3 playerVelocity;
    private bool groundedPlayer;
    private float playerSpeed = 2.0f;
    private float jumpHeight = 1.0f;
    private float gravityValue = -9.81f;

    private void Start()
    {
        controller = gameObject.AddComponent<CharacterController>();
    }

    void Update()
    {
        groundedPlayer = controller.isGrounded;
        if (groundedPlayer && playerVelocity.y < 0)
        {
            playerVelocity.y = 0f;
        }

        Vector3 move = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
        controller.Move(move * Time.deltaTime * playerSpeed);

        if (move != Vector3.zero)
        {
            gameObject.transform.forward = move;
        }

        // Changes the height position of the player..
        if (Input.GetButtonDown("Jump") && groundedPlayer)
        {
            playerVelocity.y += Mathf.Sqrt(jumpHeight * -3.0f * gravityValue);
        }

        playerVelocity.y += gravityValue * Time.deltaTime;
        controller.Move(playerVelocity * Time.deltaTime);
    }
}
