Unity:错误 CS0246:找不到类型或命名空间名称 'image'(是否缺少 using 指令或程序集引用?)”

Unity: error CS0246: The type or namespace name 'image' could not be found (are you missing a using directive or an assembly reference?)"

我试图制作一个弹药计数系统,其中的子弹图像会随着角色发射子弹而消失。我正在关注 this tutorial:

看起来没问题,但现在我得到这个错误:

"Assets \ Scripts \ GameFlow.cs (72,28): error CS0246: The type or namespace name 'image' could not be found (are you missing a directive or an assembly reference?)"

我看不出问题所在。我以为我会通过输入“using UnityEngine.UI;”来解决,但问题仍然存在。任何人都知道我该如何解决它?谢谢。

脚本中的代码是:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class GameFlow : MonoBehaviour
{
public static float remainingShots = 6;
public Transform shot1;
public Transform shot2;
public Transform shot3;
public Transform shot4;
public Transform shot5;
public Transform shot6;

// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
  if (remainingShots > 0)
  {
    shot1.GetComponent<image> ().enabled = true;
  }
  else
  {
    shot1.GetComponent<image> ().enabled = false;
  }

  if (remainingShots > 1)
  {
    shot2.GetComponent<image> ().enabled = true;
  }
  else
  {
    shot2.GetComponent<image> ().enabled = false;
  }

  if (remainingShots > 2)
  {
    shot3.GetComponent<image> ().enabled = true;
  }
  else
  {
    shot3.GetComponent<image> ().enabled = false;
  }

  if (remainingShots > 3)
  {
    shot4.GetComponent<image> ().enabled = true;
  }
  else
  {
    shot4.GetComponent<image> ().enabled = false;
  }

  if (remainingShots > 4)
  {
    shot5.GetComponent<image> ().enabled = true;
  }
  else
  {
    shot5.GetComponent<image> ().enabled = false;
  }

  if (remainingShots > 5)
  {
    shot6.GetComponent<image> ().enabled = true;
  }
  else
  {
    shot6.GetComponent<image> ().enabled = false;
  }


  if(Input.GetButtonDown("Fire1"))
  {
  remainingShots -= 1;
  }
}
}

"Assets \ Scripts \ GameFlow.cs (72,28): error CS0246: The type or namespace name 'image' could not be found (are you missing a directive or an assembly reference?)"

将所有 'image' 类型更改为 'Image'。
