Question

我正在尝试使用单击时使用速度将对象移向鼠标，但是当我单击该对象时，通常会朝不同的方向移动。我基本上从另一个项目中复制了代码，并在该项目中工作。唯一的区别是，在另一个项目而不是设置速度，我使用AddForce。是什么导致它做它正在做的事情？

using UnityEngine;
using System.Collections;

public class ShootBall : MonoBehaviour {

    public float shootDelay = 0.03f;
    public GameObject[] balls;
    bool hasShot = false;

    Vector3 clickPosition = Vector3.zero;

    // Update is called once per frame
    void Update() {
        if (Input.GetMouseButtonUp(0) && !hasShot) {
            hasShot = true;
            Vector3 point = Camera.main.ScreenToWorldPoint(Input.mousePosition);
            Vector2 direction = point - transform.position;
            StartCoroutine(Shoot(direction));
        }
    }

    IEnumerator Shoot(Vector2 direction) {
        foreach (GameObject ball in balls) {
            float speed = ball.GetComponent<Ball>().speed;
            ball.GetComponent<Ball>().rb.velocity = direction.normalized * speed;
            yield return new WaitForSeconds(shootDelay);
        }
    }
}

Answer 1

尝试在此处反转方向向量：

Vector2 direction = transform.position - point;

或者在这里：

ball.GetComponent<Ball>().rb.velocity = -direction.normalized * speed;

向鼠标单击移动
