带 1 个键盘的本地多人 2d 平台游戏 (UNITY)

Question

我正在努力使这段代码工作，刚体不能在同一个客户端上使用 2 个输入。

我找到了这个解决方案，但由于它超越了重力，它们开始漂浮并且永远不会下降。

using System.Collections.Generic;
using UnityEngine;

public class MoveArrows : MonoBehaviour
{
    public float Speed;
    float MovementY;
    float MovementX;

    Rigidbody2D rigidBody;

    // Start is called before the first frame update
    void Start()
    {
        rigidBody = GetComponent<Rigidbody2D>();

        MovementY = 0;
        MovementX = 0;
    }

    // Update is called once per frame
    void Update()
    {
        rigidBody.velocity = new Vector2(MovementX * Speed * Time.deltaTime, MovementY * Speed * Time.deltaTime);

        if (Input.GetKeyDown(KeyCode.UpArrow))
        {
            MovementY = 2;

        }

        if (Input.GetKeyDown(KeyCode.RightArrow))
        {
            MovementX = 1;
        }

        if (Input.GetKeyDown(KeyCode.LeftArrow))
        {
            MovementX = -1;
        }
    }
}

和

using System.Collections.Generic;
using UnityEngine;

public class MoveWASD : MonoBehaviour
{
    public float Speed;
    float MovementY;
    float MovementX;

    Rigidbody2D rigidBody;

    // Start is called before the first frame update
    void Start()
    {
        rigidBody = GetComponent<Rigidbody2D>();

        MovementY = 0;
        MovementX = 0;
    }

    // Update is called once per frame
    void Update()
    {
        rigidBody.velocity = new Vector2(MovementX * Speed * Time.deltaTime, MovementY * Speed * Time.deltaTime);

        if (Input.GetKeyDown(KeyCode.W))
        {
            MovementY = 2;

        }

        if (Input.GetKeyDown(KeyCode.D))
        {
            MovementX = 1;
        }

        if (Input.GetKeyDown(KeyCode.A))
        {
            MovementX = -1;
        }
    }
}

一旦我跳起来，他们就呆在那里，我尝试了 Thread.Sleep 但在 Unity 上不起作用。

我尝试了协程，也没有工作。

在用我的协程对 Y 应用负运动之前，我试图给足够的“等待”时间。

StartCoroutine(Wait());
MovementY= -1;

协程是：

 IEnumerator Wait()
{
       yield return new WaitForSeconds(.5f);
}

我的目标是在模拟重力之前留出足够的时间。

Answer 1

我忘记了 Coroutine 是异步工作的，因此我在 Async 方法中添加了“重力”。

如果您想要本地多人 2d 游戏，我将把解决方案留在这里。

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

public class MoveWASD : MonoBehaviour
{
    public float Speed;
    float MovementY;
    float MovementX;

    Rigidbody2D rigidBody;

    // Start is called before the first frame update
    void Start()
    {
        rigidBody = GetComponent<Rigidbody2D>();

        MovementY = 0;
        MovementX = 0;
    }

    // Update is called once per frame
    void Update()
    {
        rigidBody.velocity = new Vector2(MovementX * Speed * Time.deltaTime, MovementY * Speed * Time.deltaTime);

        if (Input.GetKeyDown(KeyCode.W))
        {
            MovementY = 2;
            StartCoroutine(Wait());

        }

        if (Input.GetKeyDown(KeyCode.D))
        {
            MovementX = 1;
        }

        if (Input.GetKeyDown(KeyCode.A))
        {
            MovementX = -1;
        }
    }
    IEnumerator Wait()
    {
        yield return new WaitForSeconds(.5f);
        MovementY = -1;
    }
}
