Shift+W 时的不同动作？它一直只是进入 "W" 分支，而不是让我专门编码 Shift+W

Question

好的，所以我正在尝试让不同的玩家动画和速度在玩家按下 Shift+W 时发生，而不仅仅是 W。

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，当我尝试引入 Shift+W 行为时，示例：

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

那就不行了。它只是一直进入 W 分支，从不让我专门为 Shift+W 编写行为代码。

我做错了什么？当玩家按住 Shift+W 时，我如何做出不同的行为，这与玩家仅按住 W 时不同？

您需要切换检查密钥的方式。 GetKeyDown 仅适用于您按下按键的帧 (https://docs.unity3d.com/ScriptReference/Input.GetKeyDown.html), and GetKey remains true while the key is held down (https://docs.unity3d.com/ScriptReference/Input.GetKey.html)。所以要按住 shift 然后按 W 检查应该是

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

Shift+W 时的不同动作？它一直只是进入 "W" 分支，而不是让我专门编码 Shift+W

Different movements upon Shift+W? It keeps just entering the "W" branch and not letting me exclusively code Shift+W
