1.创建画布,放置在层次列表中任何位置
2.将画布摄像机设置为space world.
3.在画布上创建一个脚本控制UI的显示和出现的位置.
4.UI出现位置的脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class WebpagePosition : MonoBehaviour {
public Transform eyesCamera;
private RectTransform rect;
void Start () {
rect = this.GetComponent<RectTransform>();
rect.position = eyesCamera.position + eyesCamera.forward*2+eyesCamera.up*(-0.2f);
Quaternion targetQua = eyesCamera.rotation;
targetQua.x = 0f;
targetQua.z = 0f;
rect.rotation = targetQua;
}
}将Camera(eyes)拖拽到脚本中即完成!
