当向上、向下、向左或向右滑动时，如何调用另一个类中的方法?单位2D

Question

我几天前开始了一个Unity项目。这是一款简单的2D自上而下的射击游戏，旨在在智能手机平台上玩。

我有一个射击脚本，它基本上有一个名为Shoot1的方法，它在子弹中产生。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Shooting : MonoBehaviour
{
public Transform firePoint;
public GameObject BulletRedPrefab;
public GameObject BulletGreenPrefab;
public float bulletForce = 20f;
// Update is called once per frame
void Start()
{
}
void Update()
{
}
public IEnumerator Shoot1()
{
yield return new WaitForSeconds(0.00001f);
GameObject bullet = Instantiate(BulletRedPrefab, firePoint.position, firePoint.rotation);
Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
rb.AddForce(firePoint.up * bulletForce, ForceMode2D.Impulse);
}
}

我还有确定滑动方向的滑动脚本，等等

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Swipe : MonoBehaviour
{
private bool tap, swipeUp, swipeDown, swipeLeft, swipeRight;
private bool isDraging = false;
private Vector2 startTouch, swipeDelta;
// Update is called once per frame
private void Update()
{
tap = swipeUp = swipeDown = swipeLeft = swipeRight = false;
if (Input.touches.Length > 0)
{
if (Input.touches[0].phase == TouchPhase.Began)
{
isDraging = true;
tap = true;
startTouch = Input.touches[0].position;
}
else if (Input.touches[0].phase == TouchPhase.Ended || Input.touches[0].phase == TouchPhase.Canceled)
{
isDraging = false;
Reset();
}
}
if (Input.GetMouseButtonDown(0))
{
tap = true;
isDraging = true;
startTouch = Input.mousePosition;
}
else if (Input.GetMouseButtonUp(0))
{
isDraging = false;
Reset();
}
swipeDelta = Vector2.zero;
if (isDraging)
{
if (Input.touches.Length > 0)
swipeDelta = Input.touches[0].position - startTouch;
else if (Input.GetMouseButton(0))
swipeDelta = (Vector2)Input.mousePosition - startTouch;
}
if (swipeDelta.magnitude > 125)
{
float x = swipeDelta.x;
float y = swipeDelta.y;
if (Mathf.Abs(x) > Mathf.Abs(y))
{
if (x < 0)
swipeLeft = true;
else
swipeRight = true;
}
else
{
if (y < 0)
swipeDown = true;
else
swipeUp = true;
}
Reset();
}
}
private void Reset()
{
startTouch = swipeDelta = Vector2.zero;
isDraging = false;
}
public Vector2 SwipeDelta { get { return swipeDelta; } }
public bool SwipeUp { get { return swipeUp; } }
public bool SwipeDown { get { return swipeDown; } }
public bool SwipeLeft { get { return swipeLeft; } }
public bool SwipeRight { get { return swipeRight; } }
}

我有一个手势检测器脚本，它的目标是每当用户向左、向右、向上或向下滑动时发射子弹。当我试图通过滑动使玩家对象(称为机器人(移动时，它起到了作用。但当我尝试用滑动从另一个类调用方法时，它不起作用。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GestrueDetector : MonoBehaviour
{
public Shooting other;
public Swipe swipeControls;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
private void Update()
{
if (GameObject.Find("robot") != null)
{
if (swipeControls.SwipeLeft)
desirePosition += Vector3.left;
other.Shoot1();
if (swipeControls.SwipeRight)
desirePosition += Vector3.right;
other.Shoot1();
if (swipeControls.SwipeUp)
desirePosition += Vector3.up;
other.Shoot1();
if (swipeControls.SwipeDown)
desirePosition += Vector3.down;
other.Shoot1();
}
}
}

本周我刚开始使用unity，所以我对这个软件还很陌生。非常感谢！

对于协同程序，您需要调用以下方法：

StartCoroutine(Shoot1());

我稍微改变了你的课程：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Shooting : MonoBehaviour
{
public Transform firePoint;
public GameObject BulletRedPrefab;
public GameObject BulletGreenPrefab;
public float bulletForce = 20f;
void Start ()
{
}
void Update()
{
}
public void Shoot()
{
StartCoroutine(Shoot1());
}
private IEnumerator Shoot1()
{
yield return new WaitForSeconds(0.00001f);
GameObject bullet = Instantiate(BulletRedPrefab, firePoint.position, firePoint.rotation);
Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();

rb.AddForce(firePoint.up * bulletForce, ForceMode2D.Impulse);
}
}

对于GestureDetector:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GestrueDetector : MonoBehaviour
{
public Shooting other;
public Swipe swipeControls;

// Start is called before the first frame update
void Start()
{

}
// Update is called once per frame
private void Update()
{
if (GameObject.Find("robot") != null)
{

if (swipeControls.SwipeLeft)
desirePosition += Vector3.left;
other.Shoot();    
if (swipeControls.SwipeRight)
desirePosition += Vector3.right;
other.Shoot();
if (swipeControls.SwipeUp)
desirePosition += Vector3.up;
other.Shoot();


if (swipeControls.SwipeDown)
desirePosition += Vector3.down;
other.Shoot();



}
}
}
