绘制小地图

1新建一个renderTexture命名为minmapTexture新建一个fps角色

2、新建一个cmeraFollow脚本并付给摄像机。

using UnityEngine;

using System.Collections;

public class cameraFollow : MonoBehaviour {

public Transform target;

void LateUpdate () {

transform .position =new Vector3 (target .position.x,transform .position .y,target.position .z);

}

}

3target为fps，并将摄像机的dipth改为1

4、给地形一个标签命名为ninmap

5、将所有的culling target 改为minmap

将main camera 的target texture 改为minimap。

6、新建一个plane 将minmaTexture托给他会制动生成一个minmapTexure 材质

7新建一个shader 命名为maskShade

8 把里面的脚本删除了然后再粘贴如下脚本。

Shader "Custom/Mask"

{

Properties

{

_MainTex ("Main Texture", 2D) = "white" {}

_Mask("Mask Texture", 2D) = "white" {}

}

SubShader

{

Tags { "Queue"="Transparent" }

Lighting On

Zwrite off

Blend SrcAlpha OneMinusSrcAlpha

Pass

{

SetTexture[_Mask]{combine texture}

SetTexture[_MainTex]{combine texture ,previous}

}

}

}

9、在photoshop中绘制你要的地图形状并保存alpha通道保存为tag格式。

并且注意要修改它的textureType为advant 并且把aphaformgrayScale勾选。

】

10、选中生成的材质shader菜单下的mask 把从ps中绘制的地图现状拖过去即生成了小地图。

11、如果看不到小地图就调节总摄像机下的normalized View port Rect改为x:0 y:0,w:1, H:1

12下面在游戏中生成小地图。

13新建一个c#脚本

输入如下代码using UnityEngine;

using System.Collections;

public class guiTexure : MonoBehaviour {

public RenderTexture minmapTexture;

public Material minmapMaterial;

//

void OnGUI () {

if( Event.current.type==EventType.Repaint )

Graphics .DrawTexture (new Rect(0,0,256,256),minmapTexture, minmapMaterial);

}

}

13将他拖到任何一个物体上using UnityEngine;

minmapTexture;为minmapTexture

minmapMaterial为生成的minmapTexture材质

运行一下小地图出来了哈哈~很好玩赶快试一下吧

方法2：

@script ExecuteInEditMode()

public var Enemy_ : Texture; //define enemy texture

public var Box_:Texture;//define the box texture

public var Player_:Texture;//define player texture

public var radarBG : Texture; //small map texture

public var centerObject : Transform; //chracter position

public var mapScale = 0.3; //地圖縮放

public var mapCenter = Vector2(50,50); //地圖中心

function OnGUI () {

bX=centerObject.transform.position.x * mapScale;

bY=centerObject.transform.position.z * mapScale;

bX=centerObject.transform.position.x * mapScale;

bY=centerObject.transform.position.z * mapScale;

GUI.DrawTexture(Rect(mapCenter.x-55,mapCenter.y-50,128,128),radarBG);

// 上面的mapCenter.x-32是地圖的x位置，mapCenter.y-32是y位置，64,64是地圖的大小

DrawBlipsForEnemies();

DrawBlipsForPlayer();

DrawBlipsForBox();

}

function DrawBlipsForBox(){ //draw box texture in small map

var gos : GameObject[];

gos = GameObject.FindGameObjectsWithTag("Box");

var distance = Mathf.Infinity;

var position = transform.position;

for (var go : GameObject in gos) {

drawBlip(go,Box_);

}

}

function DrawBlipsForPlayer(){ //draw player texture in small map

var gos : GameObject[];

gos = GameObject.FindGameObjectsWithTag("Player");

var distance = Mathf.Infinity;

var position = transform.position;

for (var go : GameObject in gos) {

drawBlip(go,Player_);

}

}

function DrawBlipsForEnemies(){ //draw enemy texture in small map

var gos : GameObject[];

gos = GameObject.FindGameObjectsWithTag("Enemy");

var distance = Mathf.Infinity;

var position = transform.position;

for (var go : GameObject in gos) {

drawBlip(go,Enemy_);

}

}

function drawBlip(go,aTexture){ //draw position in small map

centerPos=centerObject.position;

extPos=go.transform.position;

dist=Vector3.Distance(centerPos,extPos);
