C# compiler error: Assets\Scripts\CamraMotor.cs(13,41): error CS1526: A new expression requires (), [], or {} after type

Question

我正在学习 unity 中的 2D 游戏教程，但我不断收到编译错误，告诉我新表达式需要 ()、[] 或 {}，但是当我查看我的代码时，我找不到哪里出错了。

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

public class CamraMotor : MonoBehaviour
{
    public Transform lookAt;
    public float boundX = 0.15f;
    public float boundY = 0.05f;

    private void LateUpdate()
    {
        Vector3 delta = new Vector3.zero;

        // This is to see if we're on the inside the bounds om the X asxis
        float deltaX = lookAt.position.x - transform.position.x;
        if(deltaX > boundX || deltaX < -boundX)
        {
            if (transform.position.x < lookAt.position.x)
            {
                delta.x = deltaX - boundX;
            }
            else
            {
                delta.x = deltaX + boundX;
            }
        }

        // This is to see if we're inside the bounds on the Y axis
        float deltaY = lookAt.position.y - transform.position.y;
        if (deltaY > boundY || deltaY < -boundY)
        {
            if (transform.position.y < lookAt.position.y)
            {
                delta.y = deltaY - boundY;
            }
            else
            {
                delta.y = deltaY + boundY;
            }
        }

        transform.position += new Vector3(delta.x, deltaY, 0);
    }
}

说可以找到错误(13,41)

我尝试重新输入整个脚本，但仍然出现同样的错误。

Answer 1

这一行是错误的：

Vector3 delta = new Vector3.zero;

new 关键字用于创建新对象，但该对象需要一个构造函数。

删除 new 它应该可以正常工作。

这可能是您教程中的一个错误。看起来 Zero 是一个字段而不是 class，因此无法实例化。
