Vector2 不包含定义（Unity Roll A Ball 教程）

Question

所以我在做 Unity Roll-A-Ball 教程，我正在移动播放器的第 8 步。 当我键入所有代码时，它会引发错误'Vector2 does not contain a definition for 'Y' and no accessible extension method 'Y' accepting a first argument type of 'Vector2' could be found. (are you missing a using directive or an assembly reference?) 'Vector2 does not contain a definition for 'Y' and no accessible extension method 'Y' accepting a first argument type of 'Vector2' could be found. (are you missing a using directive or an assembly reference?)

任何帮助，将不胜感激

这是我的代码：

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

public class PlayerController : MonoBehaviour
{

    private Rigidbody rb;
    private float movementX;
    private float movementY;

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void OnMove(InputValue movementValue) 
    {
        //Function Body
        Vector2 movementVector = movementValue.Get<Vector2>();

        movementX = movementVector.X;
        movementY = movementVector.Y;
    }

    void FixedUpdate()
    {
        Vector3 movement = new Vector3(movementX, 0.0f, movementY);

        rb.AddForce(movement);

    }
}

Answer 1

Vector2、Vector3中的字段名是小写的x、y、z。

您可以在 IDE 中单击（设置回车位置）代表类型（如“Vector2”）的字符串，然后按 F12 以查看里面的内容或直接写：

movementVector.

并等待IDE的建议。 如果它们没有出现，请按 Ctrl + 空格键。
