Question

我想在场景上放置六个物体（球）。我认为代码看起来可行但我收到了一个控制台消息。消息：

＆＃34;资产/ GameScripts / Instance.cs（26,40）：错误CS0266：不能隐式转换类型object' to UnityEngine.Vector3＆＃39;。一个明确的转换是否存在（您是否错过了演员表？）＆＃34;

使用UnityEngine; 使用System.Collections;

public class Instance：MonoBehaviour { 公共GameObject球;

public ArrayList coordinateContainer = new ArrayList();



// Use this for initialization
void Start () {

    coordinateContainer.Add(new Vector3(1f,1f,1f));
    coordinateContainer.Add(new Vector3(2f,1f,1f));
    coordinateContainer.Add(new Vector3(3f,1f,1f));
    coordinateContainer.Add(new Vector3(4f,1f,1f));
    coordinateContainer.Add(new Vector3(5f,1f,1f));
    coordinateContainer.Add(new Vector3(6f,1f,1f));


    //ball.transform.position = new Vector3(1f,1f,1f);
    ball.transform.rotation = Quaternion.identity;

    for (int i = 0; i <  6; i++) {
        ball.transform.position = coordinateContainer[i];
        Instantiate(ball,ball.transform.position,ball.transform.rotation);
    }
}

// Update is called once per frame
void Update () {

}

}

Answer 1

由于您使用ArrayList，因此向量将存储为objects。试试这个

ball.transform.position = (Vector3)coordinateContainer[i];

使用List<Vector3>而不是ArrayList可能会更好，这样就可以避免转换（因为List<T>只能保存T类型的对象。）

无法将类型对象隐式转换为unityengine.Vector3
