本文介绍了一个Unity中的示例脚本，用于将3D世界中的立方体位置转换到UI坐标上显示。通过使用WorldToScreenPoint方法将3D坐标转换为屏幕坐标，并利用RectTransformUtility将屏幕坐标转换为UI坐标。

UGUI 3d坐标转UI坐标

public class CubePosToGUI : MonoBehaviour
{
public Canvas TheCanvas;
public GameObject CubeObj;

private RectTransform canvasRectTrans;
private RectTransform textRectTrans;

void Start()
{
canvasRectTrans = TheCanvas.GetComponent();
textRectTrans = GetComponent();
}

void Update()
{
Vector3 screenVec3Pos;
screenVec3Pos = Camera.main.WorldToScreenPoint (CubeObj.transform.position);

Vector2 screenVec2Pos = new Vector2 (screenVec3Pos.x, screenVec3Pos.y);

Vector2 textPos;

RectTransformUtility.ScreenPointToLocalPointInRectangle (canvasRectTrans,
                                                            screenVec2Pos,
                                                            TheCanvas.worldCamera,
                                                            out textPos);
   textRectTrans.anchoredPosition = textPos;
}
}

或者

public class CubePosToGUI : MonoBehaviour
{
public GameObject CubeObj;

void Update()
{
Vector3 screenVec3Pos;
screenVec3Pos = Camera.main.WorldToScreenPoint (CubeObj.transform.position);

transform.position = screenVec3Pos;
}
}
