unity纯代码实现小地图,用gameobject.find获取maincamera,在到他的位置生成一个相机名为map,垂直向下,绑定main camera,用ongui在屏幕右上角创建一个image的ui在将map相机的图像实时显示到ui里面,代码怎么写
参考GPT和自己的思路:好的,具体的代码实现如下所示:
Camera mainCamera = GameObject.Find("MainCamera").GetComponent<Camera>();
GameObject mapCameraObj = new GameObject("map");
Camera mapCamera = mapCameraObj.AddComponent<Camera>();
mapCamera.transform.position = mainCamera.transform.position;
mapCamera.transform.rotation = Quaternion.Euler(90f, mainCamera.transform.rotation.y, mainCamera.transform.rotation.z);
mapCamera.orthographic = true;
using UnityEngine;
using UnityEngine.UI;
public class MiniMap : MonoBehaviour
{
private Camera mapCamera;
private RawImage miniMapImage;
private void Start()
{
// 通过名称查找
mapCamera = GameObject.Find("map").GetComponent<Camera>();
// 或者直接引用
// mapCamera = transform.Find("map").GetComponent<Camera>();
miniMapImage = CreateMiniMapImage();
}
private RawImage CreateMiniMapImage()
{
// 创建 UI 面板
GameObject miniMapPanel = new GameObject("MiniMap Panel");
// 设置父对象为当前对象
miniMapPanel.transform.SetParent(transform, false);
// 创建 UI 图像
RawImage rawImage = miniMapPanel.AddComponent<RawImage>();
// 设置图片的贴图为 map 相机的渲染结果
rawImage.texture = mapCamera.targetTexture;
// 设置位置和大小
var rectTransform = rawImage.rectTransform;
rectTransform.anchorMin = new Vector2(1f, 1f);
rectTransform.anchorMax = new Vector2(1f, 1f);
rectTransform.pivot = new Vector2(1f, 1f);
rectTransform.sizeDelta = new Vector2(200f, 200f);
rectTransform.anchoredPosition3D = new Vector3(-10f, -10f, 0f);
return rawImage;
}
}
希望这个代码示例能够对你有所帮助!
