Question

我的错误是 Collider2d是一种类型，但像变量一样使用。无法修改transform.posistion的返回值，因为它不是变量。无法将类型vector2隐式转换为float。

继承人我的代码

using UnityEngine;
using System.Collections;

public class MoveRacket : MonoBehaviour {
    public float speed = 30;
    public string axis = "Vertical";
    public object racket = "Racket";
    public bool touchInput = true;
    public Vector2 touchPos;





    void FixedUpdate () {

        //used to not have anything in parentheses
        //float v = Input.GetAxisRaw (axis);
        float v = Input.GetAxisRaw (axis);
        GetComponent<Rigidbody2D> ().velocity = new Vector2 (0, v) * speed;
        if (Input.touchCount == 1)
        {
            Vector3 wp = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
            Vector2 touchPos = new Vector2(wp.x, wp.y);
            if (Collider2D == Physics2D.OverlapPoint(touchPos))
            {
            this.transform.position.y =  new Vector3 (wp.y,0);

        }
        }
    }
}

Answer 1

您无法将值设置为position.y / x / z，这是您获得的错误。所以而不是

this.transform.position.y =  new Vector3 (wp.y,0);

使用此

this.transform.position =  new Vector3 (0,wp.y,0);

如果你想让z和x为零，那么你就明白了。

在Unity 2D（C＃）中更改为拖动的错误
