自从你提到了`GetLocalCorners`，假设你有一个`RectTransform` => 首先通过[GetWorldCorners](https://docs.unity3d.com/ScriptReference/RectTransform.GetWorldCorners.html)获取其世界坐标，然后通过[WorldToScreenPoint](https://docs.unity3d.com/ScriptReference/Camera.WorldToScreenPoint.html)将其转换为屏幕坐标。
例如：
```csharp
RectTransform rectTransform = YOUR_TARGET_RECT_TRANSFORM;
var corners = new Vector3[4];
rectTransform.GetWorldCorners(corners);
var camera = Camera.main;
for(var i = 0; i < corners.Length; i++)
{
    corners[i] = camera.WorldToScreenPoint(corners[i]);
}

var position = YOUR_TARGET_Transform.position;
// 假设缩放已经应用到目标上，以使其与目标尺寸匹配
var size = YOUR_TARGET_Transform.lossyScale;
// 假设目标默认在XZ平面上是平的
// => 默认情况下，transform.up朝向天空
// 如果目标实际上旋转了，你需要调整这些值
var x = YOUR_TARGET_Transform.right * size.x * 0.5f;
var z = YOUR_TARGET_Transform.forward * size.z * 0.5f;
var corners = new Vector3[4];
corners[0] = position - x - z;
corners[1] = position - x + z;
corners[2] = position + x + z;
corners[3] = position + x - z;

public class TEST : MonoBehaviour
{
    public RectTransform[] images;
    // 在每帧调用一次
    void Update()
    {
        var position = transform.position;
        // 假设缩放已经应用到目标上，以使其与目标尺寸匹配
        var size = transform.lossyScale;
        // 假设目标默认在XZ平面上是平的
        // => transform.up默认朝向天空
        // 如果目标实际上旋转了，你需要调整这些值
        var x = transform.right * size.x * 0.5f;
        var z = transform.forward * size.z * 0.5f;
        var corners = new Vector3[4];
        corners[0] = position - x - z;
        corners[1] = position - x + z;
        corners[2] = position + x + z;
        corners[3] = position + x - z;
        for (var i = 0; i < 4; i++)
        {
            corners[i] = Camera.main.WorldToScreenPoint(corners[i]);
            images[i].position = (Vector2)corners[i];
        }
    }
}

这就是你提供的代码的翻译。

Since you speak of `GetLocalCorners` assuming you have a `RectTransform` =&gt; You would first go through [GetWorldCorners](https://docs.unity3d.com/ScriptReference/RectTransform.GetWorldCorners.html) then pass those through [WorldToScreenPoint](https://docs.unity3d.com/ScriptReference/Camera.WorldToScreenPoint.html)
so e.g.
    RectTransform rectTransform = YOUR_TARGET_RECT_TRANSFORM;
    var corners = new Vector3[4];
    rectTransform.GetWorldCorners(corners);
    var camera = Camera.main;
    for(var i = 0; i &lt; corners.Length; i++)
    {
        corners[i] = camera.WorldToScreenPoint(corners[i]);
    }
Now the `corners` are in pixel screen space.
---
If the target is actually not a `RectTransform` you would need to calculate the corners in worldspace yourself first. Might look somewhat like e.g.
    var position = YOUR_TARGET_Transform.position;
    // assuming that scale is applied to the target so that it matches with the target dimensions 
    var size = YOUR_TARGET_Transform.lossyScale;
    // assuming your target is by default flat on the XZ plane
    // =&gt; transform.up points towards the sky by default
    // if the target is actually rotated you need to adjust those
    var x = YOUR_TARGET_Transform.right * size.x * 0.5f;
    var z = YOUR_TARGET_Transform.forward * size.z * 0.5f;
    var corners = new Vector3[4];
    corners[0] = position - x - z;
    corners[1] = position - x + z;
    corners[2] = position + x + z;
    corners[3] = position + x - z;
Little demo of that
    public class TEST : MonoBehaviour
    {
        public RectTransform[] images;
    
        // Update is called once per frame
        void Update()
        {
            var position = transform.position;
    
            // assuming that scale is applied to the target so that it matches with the target dimensions 
            var size = transform.lossyScale;
    
            // assuming your target is by default flat on the XZ plane
            // =&gt; transform.up points towards the sky by default
            // if the target is actually rotated you need to adjust those
            var x = transform.right * size.x * 0.5f;
            var z = transform.forward * size.z * 0.5f;
            var corners = new Vector3[4];
            corners[0] = position - x - z;
            corners[1] = position - x + z;
            corners[2] = position + x + z;
            corners[3] = position + x - z;
    
            for (var i = 0; i &lt; 4; i++)
            {
                corners[i] = Camera.main.WorldToScreenPoint(corners[i]);
    
                images[i].position = (Vector2)corners[i];
            }
        }
    }
