【教程】<教程>unity3d小地图制作方法 unity5.0.1 uGUI
只看楼主收藏回复

幻梦如戏
等级：
圆形小地图，
可实现远近调节
方向标示

这是PlayerIcon，是要在小地图显示你的位置和方向的。很简单，创建一个Quad然后作为你的Player的子物体就欧了。材质想必大家不用说怎么创建添加了，贴图是我在PS随便画的。

现在把代码部分贴上来

两个脚本，一个是用于zoom,一个用于方向。
新建C#脚本命名为ZoomMiniMap，将其挂载到MinimapCamera,参考前面的MiniMapCamera检视面板。脚本如下

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class ZoomMiniMap : MonoBehaviour {
public Transform playerIcon;
public float speed = 10f;
Camera c;
bool canZoomIn;
bool canZoomOut;
float ratio;
void Start ()
{
c = GetComponentCamera ();
canZoomIn = false;
canZoomOut = false;

ratio = playerIcon.localScale.x / c.orthographicSize;
}

// Update is called once per frame
void Update ()
{

if (canZoomIn)
{
c.orthographicSize -= speed * Time.deltaTime;
playerIcon.localScale -= (new Vector3(ratio,ratio,0f)) * speed * Time.deltaTime;
}

else if (canZoomOut)
{
c.orthographicSize += speed * Time.deltaTime;
playerIcon.localScale += (new Vector3(ratio,ratio,0f)) * speed * Time.deltaTime;
}

c.orthographicSize = Mathf.Clamp (c.orthographicSize, 30f, 300f);
playerIcon.localScale = new Vector3 (Mathf.Clamp (playerIcon.localScale.x, ratio * 30f, ratio * 300f), Mathf.Clamp (playerIcon.localScale.x, ratio * 30f, ratio * 300f), 1f);

}
public void ZoomIn()
{
canZoomIn = true;
}

public void ZoomOut()
{
canZoomOut = true;
}

public void UnZoom()
{
canZoomOut = canZoomIn = false;
}
}

并将你的Player拖放进Player.

代码如下

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class Direction : MonoBehaviour {

public Transform player;
RectTransform tr;

void Start () {
tr = GetComponentRectTransform ();

}

void Update ()
{
Quaternion rotation = Quaternion.identity;
rotation.eulerAngles = new Vector3 (0f, 0f, player.rotation.eulerAngles.y);
tr.rotation = rotation;

}
}
