小地圖

小地圖如何制作呢，首先我們創(chuàng)建一個小地圖的攝像機(jī)讓人物對象成為其父對象、

Paste_Image.png

隨后我們創(chuàng)建一個Render Texture并命名為Minimap，再將Minimap拖入我們小地圖攝像機(jī)的Target Texture上這樣我們的Minimap就取得了攝像機(jī)上的圖像了.

然后創(chuàng)建一個Image將Minimap材質(zhì)進(jìn)去就OK了。

 private Camera minimapCamera;

    void Start() {
        minimapCamera = GameObject.FindGameObjectWithTag(Tags.minimap).GetComponent<Camera>();
    }

    public void OnZoomInClick() {
        //放大
        minimapCamera.orthographicSize--;
    }
    public void OnZoomOutClick() {
        //縮小
        minimapCamera.orthographicSize++;
    }
