我为我的 2D 游戏制作了动画，但我的角色没有移动

Question

我一直在按照 Brackeys 的教程制作 2D 游戏，现在我正在制作动画。动画播放他攻击，精灵翻转两个方向等。但仍然停留在同一个位置。我已经观看并重新观看了教程，但无法弄清楚。

在添加动画之前，一切都很完美。他在屏幕上移动，他跳了，等等。所以我知道他不动与尝试动画直接相关

这是我按照他的教程制作的 playermovement 脚本。

public class playermovement : MonoBehaviour
{
    public CharacterController2D controller;
    public Animator animator;

    public float runSpeed = 40f;

    float horizontalMove = 0f;
    bool jump = false;
    bool Attack = false;

    void Update()
    {
        horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;

        animator.SetFloat("Speed", Mathf.Abs(horizontalMove));

        if (Input.GetButtonDown("Jump"))
        {
            jump = true;
            animator.SetBool("IsJumping", true);
        }

        if (Input.GetKeyDown(KeyCode.Mouse0))
        {
            animator.SetBool("Attack", true);
            Attack = false;
        }
    }
    public void OnLanding ()     
    {
        animator.SetBool("IsJumping", false);
    }



    private void FixedUpdate()
    {
        controller.Move(horizontalMove * Time.fixedDeltaTime, false, jump);
        jump = false;

    }
}

这是我的角色控制器

public class CharacterController2D : MonoBehaviour
{
    [SerializeField] private float m_JumpForce = 400f;                          // Amount of force added when the player jumps.

    [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;

Answer 1

现在帮助 OP 可能有点晚了，但我今天遇到了完全相同的问题，终于解决了。 我正在为我的一些动画缩放主要对象。为了修复它，我进入并删除了主容器对象的任何缩放，而是单独缩放内部对象，现在翻转工作了。

显然动画缩放会干扰控制器翻转缩放。

尝试此代码，但请确保您的角色具有 2DRigidbody 和 2DBoxcollider，并注意脚本名称为“Character2DController” 希望对你有帮助;)

using UnityEngine;

public class Character2DController : MonoBehaviour
{
    public float MovementSpeed = 1;
    public float JumpForce = 1;
    public Animator animator;
    private bool facingRight; 

    private Rigidbody2D _rigidbody;
    void Start()
    {
        facingRight = true;
        _rigidbody = GetComponent<Rigidbody2D>();
    }
            
    void Update()

    {
        if (Input.GetAxis("Horizontal") < 0)
       {
           transform.localScale = new Vector2 (-1.5f, transform.localScale.y);
        }
        if (Input.GetAxis("Horizontal") > 0)
        {
            transform.localScale = new Vector2(1.5f, transform.localScale.y);
        }

        var movement = Input.GetAxis("Horizontal");

        transform.position += new Vector3(movement, 0, 0) * Time.deltaTime * MovementSpeed;

        animator.SetFloat("Movement Speed", Mathf.Abs(movement));

        {

        }

        if ((Input.GetKeyDown(KeyCode.UpArrow) || Input.GetKeyDown(KeyCode.W) || Input.GetButtonDown("Jump")) && Mathf.Abs(_rigidbody.velocity.y) < 0.001f)
        {
            _rigidbody.AddForce(new Vector2(0, JumpForce), ForceMode2D.Impulse);
        }
    }`enter code here`

}

您可以在调试时检查来自horizontalMove 的值，或添加Debug.Log 语句以在测试时检查其值，以确保该值是预期的值。

还要确保分配了controller。
