I will tell you how can will make a player movement in unity easily.
Make a New Project in unity.
After making New project create a Ground.
I have create a Empty object name Player and inside that i have created my player that is Cube.
Now select player and Add Rigidbody Component for Real Physics and Character controller for control our player and adjust Height and radius According to the Player shape
✅Check the box of Is Kinematic in RigidBody
Now Create a New C# Script for Control player 📁PlayerMovement.cs
And Attach with Player Components like this you can drag and drop
Now this is Coding Time
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
// Variables
[SerializeField] private float moveSpeed;
[SerializeField] private float walkSpeed = 10f;
[SerializeField] private float runSpeed;
// References
private Vector3 moveDirection;
private CharacterController characterController;
void Start()
{
// Asisign Character Controller components in Variable
characterController = GetComponent<CharacterController>();
}
void Update()
{
Move();
}
private void Move()
{
float moveX = Input.GetAxis("Horizontal");
float moveZ= Input.GetAxis("Vertical"); // if we press w then 1 and when press s then -1
moveDirection = new Vector3(moveX, 0, moveZ);
moveDirection = moveDirection * walkSpeed;
characterController.Move(moveDirection*Time.deltaTime);
}
}
Now the player Basic movement is Completed
If your character is not on the ground then do this
Skin Width make Minimum
Now Make Running and Walking Script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
// Variables
[SerializeField] private float moveSpeed = 5f;
[SerializeField] private float walkSpeed = 5f;
[SerializeField] private float runSpeed = 10f;
// References
private Vector3 moveDirection;
private CharacterController characterController;
void Start()
{
// Asisign Character Controller components in Variable
characterController = GetComponent<CharacterController>();
}
void Update()
{
Move();
}
private void Move()
{
float moveX = Input.GetAxis("Horizontal");
float moveZ= Input.GetAxis("Vertical"); // if we press w then 1 and when press s then -1
moveDirection = new Vector3(moveX, 0, moveZ);
// moveDirection = moveDirection * walkSpeed;
if (moveDirection != Vector3.zero && !Input.GetKey(KeyCode.LeftShift))
{
// Walk
Walk();
}
else if(moveDirection != Vector3.zero && Input.GetKey(KeyCode.LeftShift))
{
// Run
Run();
}
else if(moveDirection != Vector3.zero)
{
// Idle
Idle();
}
moveDirection = moveDirection * moveSpeed;
characterController.Move(moveDirection*Time.deltaTime);
}
void Idle()
{
}
void Walk()
{
moveSpeed = walkSpeed;
}
void Run()
{
moveSpeed = runSpeed;
}
}
Make This type of Function for better understanding
Now make Jump and Check Player is Standing on The ground or Not
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
// Variables
private Vector3 moveDirection;
private Vector3 velocity;
[SerializeField] private float moveSpeed = 5f;
[SerializeField] private float walkSpeed = 5f;
[SerializeField] private float runSpeed = 10f;
[SerializeField] private bool isGrounded;
[SerializeField] private float groundCheckDistance = 1f;
[SerializeField] private LayerMask groundMask;
[SerializeField] private float gravity = -9.81f;
[SerializeField] private float jumpHeight = 1f;
// References
private CharacterController characterController;
void Start()
{
// Asisign Character Controller components in Variable
characterController = GetComponent<CharacterController>();
}
void Update()
{
Move();
}
private void Move()
{
isGrounded = Physics.CheckSphere(transform.position, groundCheckDistance, groundMask);
if (isGrounded && velocity.y<0)
{
velocity.y = -2f;
}
float moveX = Input.GetAxis("Horizontal");
float moveZ= Input.GetAxis("Vertical"); // if we press w then 1 and when press s then -1
moveDirection = new Vector3(moveX, 0, moveZ);
// moveDirection = moveDirection * walkSpeed;
if (isGrounded)
{
if (moveDirection != Vector3.zero && !Input.GetKey(KeyCode.LeftShift))
{
// Walk
Walk();
}
else if(moveDirection != Vector3.zero && Input.GetKey(KeyCode.LeftShift))
{
// Run
Run();
}
else if(moveDirection != Vector3.zero)
{
// Idle
Idle();
}
moveDirection = moveDirection * moveSpeed;
if(Input.GetKeyDown(KeyCode.Space))
{
Jump();
}
}
characterController.Move(moveDirection*Time.deltaTime);
// apply gravity
velocity.y += gravity * Time.deltaTime;
// Apply to the charachter
characterController.Move(velocity*Time.deltaTime);
}
void Idle()
{
}
void Walk()
{
moveSpeed = walkSpeed;
}
void Run()
{
moveSpeed = runSpeed;
}
void Jump()
{
velocity.y = Mathf.Sqrt(jumpHeight *-2* gravity);
}
}
Note : Make sure You ground component contating ground layer .
Give Ground Mask to your ground layer and other thing now you can jump
