播放器跳跃动画未在 unity2d 中播放

Question

这几天我的跳跃动画一直有一些问题，我想知道如何制作它，所以当我按下“SPACE”键时，它会播放我的跳跃动画。我的动画师中已经有一个名为 isJumping 的布尔函数，只是我不知道如何在脚本中调用它来播放我的跳跃动画。我尝试了很多教程来找出我的答案，但其中大多数并没有很好地解释如何做到这一点。我已经设置了我的行走动画，只是我知道需要知道如何制作我的跳跃动画。

到目前为止我的代码

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

public class PM : MonoBehaviour
{


public float moveSpeed;
public float jumpHeight;
Rigidbody2D rb;
BoxCollider2D boxColliderPlayer;
int layerMaskGround;
float heightTestPlayer;
public Animator animator;

    void Start()
{
    rb = GetComponent<Rigidbody2D>();

    // Get the player's collider so we can calculate the height of the character.
    boxColliderPlayer = GetComponent<BoxCollider2D>();
    // We do the height test from the center of the player, so we should only check
    // halft the height of the player + some extra to ignore rounding off errors.
    heightTestPlayer = boxColliderPlayer.bounds.extents.y + 0.05f;
    // We are only interested to get colliders on the ground layer. If we would
    // like to jump ontop of enemies we should add their layer too (which then of
    // course can't be on the same layer as the player).
    layerMaskGround = LayerMask.GetMask("Ground");
}

    void Update()
    {
    float moveDir = Input.GetAxis("Horizontal") * moveSpeed;
    rb.velocity = new Vector2(moveDir, rb.velocity.y);

    // Your jump code:
    if (Input.GetKeyDown(KeyCode.Space) && IsGrounded() )
    {
        rb.velocity = new Vector2(rb.velocity.x, jumpHeight);
    }
    animator.SetFloat("Speed",Mathf.Abs(moveDir));
    }


    /// <summary>
    /// Simple check to see if our character is no the ground. 
    /// </summary>
    /// <returns>Returns <c>true</c> if the character is grounded.</returns>
    private bool IsGrounded()
    {
    // Note that we only check for colliders on the Ground layer (we don't want to hit ourself). 
    RaycastHit2D hit = Physics2D.Raycast(boxColliderPlayer.bounds.center, Vector2.down, heightTestPlayer, layerMaskGround);
    bool isGrounded = hit.collider != null;
    // It is soo easy to make misstakes so do a lot of Debug.DrawRay calls when working with colliders...
    Debug.DrawRay(boxColliderPlayer.bounds.center, Vector2.down * heightTestPlayer, isGrounded ? Color.green : Color.red, 0.5f);
    return isGrounded;
 }
}

我不知道您的动画树是如何设置的。为此，请从您的其他状态进行转换，如果 isJump 设置为 true，那么它将从任何状态转换为跳跃（当然跳跃除外），然后退出您的跳跃回到入口或空闲或其他状态跳跃结束时的状态是最有意义的。如果您发布树的图像，我可以在需要时为您提供帮助。

使用带有布尔值的转换和单独的状态设置来触发转换，播放动画所需的唯一代码应该是：

animator.SetBool("isJumping", true);

一旦您在 isGrounded 函数中检测到玩家再次接地，请使用相同的 sn-p 但传入 false 以停止跳跃动画。

animator.SetBool("isJumping", false);
