在Unity中找不到rigidBody2D.MovePosition

Question

我是Unity的新手。虽然我正在关注＆＃34; Catch Game＆＃34的视频教程;我正在使用Unity 4.3.3版本。

这是我的代码。

using UnityEngine;
using System.Collections;

public class BasketController : MonoBehaviour {

    public Camera cam;
    // Use this for initialization
    void Start () {
        if (cam == null) 
        {
            cam = Camera.main;      
        }
    }

    // Update is called once physics TimeStep  
    void FixedUpdate () {
        Vector3 rawPosition = cam.ScreenToWorldPoint (Input.mousePosition);
        Vector3 targetPosition = new Vector3 (rawPosition.x, 0.0f, 0.0f);
        rigidbody2D.MovePosition (targetPosition);
    }
}

我收到以下错误。

error CS1061: Type `UnityEngine.Rigidbody2D' does not contain a definition for `MovePosition' and no extension method `MovePosition' of type `UnityEngine.Rigidbody2D' could be found (are you missing a using directive or an assembly reference?)

请更正我的错误。谢谢。

您需要使用Unity 4.5或更高版本才能使用Rigidbody2D.MovePosition： http://forum.unity3d.com/threads/cannot-figure-out-my-error.253139/

作为解决方法，您可以使用：

rigidbody2D.position = targetPosition;
