minmap

小地图的计算方式还有大小有问题 

Minmap.cs

using UnityEngine;using System.Collections;public class Minmap : MonoBehaviour {GameObject plane;GameObject cube;float mapWidth;float mapHeight;float widthCheck;float heightCheck;float mapcube_x =0;float mapcube_y =0;bool keyUp;bool keyDown;bool keyLeft;bool keyRight;public Texture map;public Texture map_cube;// Use this for initializationvoid Start () {plane = GameObject.Find("Plane");cube = GameObject.Find ("Cube");float size_x = plane.GetComponent<MeshFilter> ().mesh.bounds.size.x; //??float scal_x = plane.transform.localScale.x;float size_z = plane.GetComponent<MeshFilter> ().mesh.bounds.size.z;float scal_z = plane.transform.localScale.z;mapWidth = size_x * scal_x;mapHeight = size_z * scal_z;widthCheck = mapWidth / 2;heightCheck = mapHeight / 2;check ();}void OnGUI(){keyUp=GUILayout.RepeatButton("向前移动");keyDown=GUILayout.RepeatButton("向后移动");keyLeft=GUILayout.RepeatButton("向左移动");keyRight=GUILayout.RepeatButton("向右移动");GUI.DrawTexture (new Rect (Screen.width - map.width, 0, map.width, map.height),map);GUI.DrawTexture (new Rect (mapcube_x, mapcube_y, map_cube.width, map_cube.height), map_cube);}// Update is called once per framevoid Update () {}void FixedUpdate(){if (keyUp) {cube.transform.Translate(Vector3.forward * Time.deltaTime * 5);check();}if (keyDown) {cube.transform.Translate(-Vector3.forward * Time.deltaTime * 5);check();}if (keyLeft) {cube.transform.Translate(-Vector3.right * Time.deltaTime * 5);check();}if (keyRight) {cube.transform.Translate(Vector3.right * Time.deltaTime * 5);check();}}void check(){float x = cube.transform.position.x;float z = cube.transform.position.z;if (x >= widthCheck) {x =widthCheck;}if (x <= -widthCheck) {x = -widthCheck;}if (z >= heightCheck) {z = heightCheck;}if (z <= -heightCheck) {z = -heightCheck;}cube.transform.position = new Vector3 (x, cube.transform.position.y, z);mapcube_x = (map.width / mapWidth * x) + ((map.width / 2) - (map_cube.width / 2)) + (Screen.width - map.width);mapcube_y = map.height - ((map.height/mapHeight * z)+(map.height/2));}}

搞定计算方式 了  期间又犯了 坐标原点不一致导致的计算错误   与教程不一样是由于  plane与cube 都不在原点 计算值时得考虑当前坐标

新的代码 计算上改了很多
