绘制小地图.doc

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14、给地形一个标签命名为ninmap5、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maskShade8 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 OnZwrite offBlend SrcAlpha OneMinusSrcAlphaPassSetTexture_Maskcombine textureSetTexture_MainTexcombine texture ,previous9、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 texturepublic var Box_:Texture;/define the box texturepublic var Player_:Texture;/define player texturepublic var radarBG : Texture; /small map texturepublic var centerObject : Transform; /chracter positionpublic 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); dx=centerPos.x-extPos.x; dz=centerPos.z-extPos.z; deltay=Mathf.Atan2(dx,dz)*Mathf.Rad2Deg - 270 - centerObject.eulerAngles.y; bX=dist*Mathf.Cos(deltay * Math
