如何解决不存在的错误转换?

[英]How can I fix the errors transform not exist?

using UnityEngine;
using System.Collections;

public class MakeTwoPoints3D : MonoBehaviour {

    public GameObject cylinderPrefab;

    // Use this for initialization
    void Start () {

        CreateCylinderBetweenPoints(Vector3.zero, new Vector3(10, 10, 10), 0.5f);

    }

    void CreateCylinderBetweenPoints(Vector3 start, Vector3 end, float width)
    {
        var offset = end - start;
        var scale = new Vector3(width, offset.magnitude / 2.0f, width);
        var position = start + (offset / 2.0f);


        Object cylinder = Instantiate(cylinderPrefab, position, Quaternion.identity);
        cylinder.transform.up = offset;
        cylinder.transform.localScale = scale;
    }

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

    }
}

在两行上出现相同的错误:

cylinder.transform.up = offset;
cylinder.transform.localScale = scale;

严重性代码说明项目文件行抑制状态错误CS1061“对象”不包含“变换”的定义,并且找不到找到接受类型为“对象”的第一个参数的扩展方法“变换”(您是否缺少using指令或程序集引用?)MakeTwoPoints3D.cs 23有效

ObjectGameObject父类,并且GameObjectTransform类型的成员。 如果尝试从Object类的实例访问transform ,它将显示以下错误:

对象”不包含“变换”的定义

如此精确的实例化和将结果对象用作GameObject的方法,正如Quantic在评论中所说:

GameObject cylinder = Instantiate(cylinderPrefab, position, Quaternion.identity) as GameObject;

要么

GameObject cylinder = (GameObject) Instantiate(cylinderPrefab, position, Quaternion.identity);

对于非GameObject的其他类型,在使用组件之前始终应使用null检查以确保安全。 例如:

Rigidbody rb = Instantiate(somePrefab) as Rigidbody;
if(rb != null)
  // use it here

希望这可以帮助。
