Yesterday i stardet with programming games i wanted to make a 2d game but i dont know how to do 2d movement and i watched yt but it never worked here are 2 scripts that i use now but it dont work i cant walk jump or crouch
This script is downloaded (CharacterController2D
using UnityEngine;
using UnityEngine.Events;
public class CharacterController2D : MonoBehaviour
{
[SerializeField] private float m_JumpForce = 400f; // Amount of force added when the player jumps.
[Range(0, 1)] [SerializeField] private float m_CrouchSpeed = .36f; // Amount of maxSpeed applied to crouching movement. 1 = 100%
[Range(0, .3f)] [SerializeField] private float m_MovementSmoothing = .05f; // How much to smooth out the movement
[SerializeField] private bool m_AirControl = false; // Whether or not a player can steer while jumping;
[SerializeField] private LayerMask m_WhatIsGround; // A mask determining what is ground to the character
[SerializeField] private Transform m_GroundCheck; // A position marking where to check if the player is grounded.
[SerializeField] private Transform m_CeilingCheck; // A position marking where to check for ceilings
[SerializeField] private Collider2D m_CrouchDisableCollider; // A collider that will be disabled when crouching
const float k_GroundedRadius = .2f; // Radius of the overlap circle to determine if grounded
private bool m_Grounded; // Whether or not the player is grounded.
const float k_CeilingRadius = .2f; // Radius of the overlap circle to determine if the player can stand up
private Rigidbody2D m_Rigidbody2D;
private bool m_FacingRight = true; // For determining which way the player is currently facing.
private Vector3 m_Velocity = Vector3.zero;

Collider2D[ ] colliders = Physics2D.OverlapCircleAll(m_GroundCheck.position, k_GroundedRadius, m_WhatIsGround);

}
// Move the character by finding the target velocity
Vector3 targetVelocity = new Vector2(move * 10f, m_Rigidbody2D.velocity.y);
// And then smoothing it out and applying it to the character

// If the input is moving the player right and the player is facing left…
if (move > 0 && !m_FacingRight)
{
// … flip the player.
Flip();
}
// Otherwise if the input is moving the player left and the player is facing right…
else if (move < 0 && m_FacingRight)
{
// … flip the player.
Flip();
}
}
// If the player should jump…
if (m_Grounded && jump)

From me (PlayerMovement)
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour{
public CharacterController2D controller;
public float runSpeed = 40f;
float horizontalMove = 0f;
bool jump = false;
bool crouch = false;
void Update(){
horizontalMove = Input.GetAxisRaw(“Horizontal”) * runSpeed;
if (Input.GetButtonDown(“Jump”))
{
jump = true;
}
if (Input.GetButtonDown(“Crouch”))
{
crouch = true;
} else if (Input.GetButtonUp(“Crouch”))
{
crouch = false;
}
}
void Fixedupdate (){
controller.Move(horizontalMove * Time.fixedDeltaTime, crouch, jump);
jump = false;
}
}
That 2 scripts i used and unity give me 3 errors that i dont know what it mean. I can start the game but dont walk
