如何让卡片出现在屏幕上- Unity，C#

using UnityEngine;

public class CardController : MonoBehaviour
{
    // 卡片的预制体
    public GameObject cardPrefab;

    void Start()
    {
        // 创建卡片实例
        GameObject card = Instantiate(cardPrefab);
        
        // 设置卡片的位置和旋转
        card.transform.position = new Vector3(0, 0, 0);
        card.transform.rotation = Quaternion.identity;
        
        // 将卡片设置为当前场景的子对象
        card.transform.parent = transform;
    }
}
