改进这个问题

我想添加一个c#脚本，它将帮助我向我移动的方向冲刺，只使用'空格'键。以下是我的角色的脚本

Answer 1

你的脚本应该是这样的，试试这个。我加了一个bool，当你按空格键时，这个bool就会变成true... ...

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

public class PinkCharacter : MonoBehaviour
{

Vector3 MoveDirection;
float moveSpeed = 5;
float dashSpeed = 10;
bool canDash;

// Update is called once per frame
void Update()
{
    if (Input.GetKey(KeyCode.A))
    {
        MoveDirection = Vector3.left;
    }
    if (Input.GetKey(KeyCode.D))
    {
        MoveDirection = Vector3.right;
    }
    if (Input.GetKey(KeyCode.W))
    {
        MoveDirection = Vector3.up;
    }
    if (Input.GetKey(KeyCode.S))
    {
        MoveDirection = Vector3.down;
    }

    canDash = Input.GetKey(KeyCode.Space);

    if (canDash)
        transform.position += MoveDirection * dashSpeed * Time.deltaTime;
    else
        transform.position += MoveDirection * moveSpeed * Time.deltaTime;
}
}

或者... [这一项有一个简化的 Update 方法]

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

public class PinkCharacter : MonoBehaviour
{

Vector3 MoveDirection;
float moveSpeed = 5;
bool canDash;

// Update is called once per frame
void Update()
{
    if (Input.GetKey(KeyCode.A))
    {
        MoveDirection = Vector3.left;
    }
    if (Input.GetKey(KeyCode.D))
    {
        MoveDirection = Vector3.right;
    }
    if (Input.GetKey(KeyCode.W))
    {
        MoveDirection = Vector3.up;
    }
    if (Input.GetKey(KeyCode.S))
    {
        MoveDirection = Vector3.down;
    }

    canDash = Input.GetKey(KeyCode.Space);

    moveSpeed = canDash ? 10 : 5;
    transform.position += MoveDirection * moveSpeed * Time.deltaTime;
}
}
