Question

好的，所以我试图让玩家按Shift + W而不是W时产生不同的玩家动画和速度。

这是W的工作代码：

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

public class MherControls : MonoBehaviour
{

    float speed = 2;
    float rotSpeed = 80;
    float rot = 0f; //0 when we start the game
    float gravity = 8;

    Vector3 moveDir = Vector3.zero;

    CharacterController controller;
    Animator anim;

    // Start is called before the first frame update
    void Start()
    {
        controller = GetComponent<CharacterController>();
        anim = GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        //anim condition 0 = idle, 1 = walk, 2 = run

        if (controller.isGrounded)
        {
            if (Input.GetKey(KeyCode.W))
            {
                anim.SetInteger("condition", 1); //changes condition in Animator Controller to 1

                moveDir = new Vector3(0, 0, 1); //only move on the zed axis
                moveDir *= speed;                 

                moveDir = transform.TransformDirection(moveDir); 


                if (speed < 10){
                    speed += Time.deltaTime; //max speed is 10
                    //Debug.Log(speed);
                }
                if (speed >= 2.5)
                {
                    anim.SetInteger("condition", 2);
                }



            }
            if (Input.GetKeyUp(KeyCode.W))
            {
                anim.SetInteger("condition", 0); 
                speed = 2;
                moveDir = new Vector3(0, 0, 0); 
            }



            rot += Input.GetAxis("Horizontal") * rotSpeed * Time.deltaTime; //horizontal are A and D keys and also left and right arrows
            transform.eulerAngles = new Vector3(0, rot, 0); //our character's transform property

        }
            //every frame move player on y axis by 8. so lowering to the ground
            moveDir.y -= gravity * Time.deltaTime;
            controller.Move(moveDir * Time.deltaTime);
    }
}

但是，当我尝试介绍Shift + W行为时，例如：

if ( (Input.GetKey(KeyCode.W)) && (Input.GetKeyDown(KeyCode.LeftShift)) {
      speed = 2;
      anim.SetInteger("condition", 1);
}

然后它不起作用。它只是一直进入W分支，从不让我为Shift + W专门编码行为。

我在做什么错？当播放器按住Shift + W时，与播放器仅按住W时，我该如何做出不同的行为？

您需要切换检查密钥的方式。 GetKeyDown仅适用于您按下键（https://docs.unity3d.com/ScriptReference/Input.GetKeyDown.html）的帧，而按住键（https://docs.unity3d.com/ScriptReference/Input.GetKey.html）时GetKey仍为true。因此，要按住shift键，然后按W键，检查应该是

if ( (Input.GetKey(KeyCode.LeftShift)) && (Input.GetKeyDown(KeyCode.W)) {
      speed = 2;
      anim.SetInteger("condition", 1);
}

Shift + W时有不同的动作吗？它一直只是进入“ W”分支，而不是让我独享Shift + W
