Unity3D实现人物移动示例

技术  /  管理员 发布于 7年前   308

一个是通过W、A、S、D来移动人物（示例一），另个是按屏幕上的按钮来移动人物（示例二）。很简单，只改了几行代码。

下面是“Assets”文件夹里面的资源。

示例一：

using System.Collections;using System.Collections.Generic;using UnityEngine; public class E3_07keyboard : MonoBehaviour{ //动画数组 private Object[] animUp; private Object[] animDown; private Object[] animLeft; private Object[] animRight; //地图贴图 private Texture2D map; //当前人物动画 private Object[] tex; //人物X坐标 private int x; //人物Y坐标 private int y; //帧序列 private int nowFram; //动画帧的总数 private int mFrameCount; //限制一秒多少帧 private float fps = 5; //限制帧的时间  private float time = 0; void Start() {  //得到帧动画中的所有图片资源  animUp = Resources.LoadAll("up");  animDown = Resources.LoadAll("down");  animLeft = Resources.LoadAll("left");  animRight = Resources.LoadAll("right");  //得到地图资源  map = (Texture2D)Resources.Load("map/map");  //设置默认动画  tex = animUp; }  void OnGUI() {  //绘制贴图  GUI.DrawTexture(new Rect(0, 0, Screen.width, Screen.height), map, ScaleMode.StretchToFill, true, 0);   //绘制帧动画  DrawAnimation(tex, new Rect(x, y, 32, 48));   //点击按钮移动人物  if (Input.GetKey(KeyCode.W))  {   y -= 2;   tex = animUp;  }  if (Input.GetKey(KeyCode.S))  {   y += 2;   tex = animDown;  }  if (Input.GetKey(KeyCode.A))  {   x -= 2;   tex = animLeft;  }  if (Input.GetKey(KeyCode.D))  {   x += 2;   tex = animRight;  } }   void DrawAnimation(Object[] tex, Rect rect) {  //绘制当前帧  GUI.DrawTexture(rect, (Texture)tex[nowFram], ScaleMode.StretchToFill, true, 0);  //计算限制帧时间  time += Time.deltaTime;  //超过限制帧则切换图片  if (time >= 1.0 / fps)  {   //帧序列切换   nowFram++;   //限制帧清空   time = 0;   //超过帧动画总数从第0帧开始   if (nowFram >= tex.Length)   {    nowFram = 0;   }  } }}

示例二

using System.Collections;using System.Collections.Generic;using UnityEngine; public class E3_07button : MonoBehaviour{ //动画数组 private Object[] animUp; private Object[] animDown; private Object[] animLeft; private Object[] animRight; //地图贴图 private Texture2D map; //当前人物动画 private Object[] tex; //人物X坐标 private int x; //人物Y坐标 private int y; //帧序列 private int nowFram; //动画帧的总数 private int mFrameCount; //限制一秒多少帧 private float fps = 5; //限制帧的时间  private float time = 0; void Start() {  //得到帧动画中的所有图片资源  animUp = Resources.LoadAll("up");  animDown = Resources.LoadAll("down");  animLeft = Resources.LoadAll("left");  animRight = Resources.LoadAll("right");  //得到地图资源  map = (Texture2D)Resources.Load("map/map");  //设置默认动画  tex = animUp; }  void OnGUI() {  //绘制贴图  GUI.DrawTexture(new Rect(0, 0, Screen.width, Screen.height), map, ScaleMode.StretchToFill, true, 0);   //绘制帧动画  DrawAnimation(tex, new Rect(x, y, 32, 48));   //点击按钮移动人物  if (GUILayout.RepeatButton("向上"))  {   y -= 2;   tex = animUp;  }  if (GUILayout.RepeatButton("向下"))  {   y += 2;   tex = animDown;  }  if (GUILayout.RepeatButton("向左"))  {   x -= 2;   tex = animLeft;  }  if (GUILayout.RepeatButton("向右"))  {   x += 2;   tex = animRight;  } }   void DrawAnimation(Object[] tex, Rect rect) {  //绘制当前帧  GUI.DrawTexture(rect, (Texture)tex[nowFram], ScaleMode.StretchToFill, true, 0);  //计算限制帧时间  time += Time.deltaTime;  //超过限制帧则切换图片  if (time >= 1.0 / fps)  {   //帧序列切换   nowFram++;   //限制帧清空   time = 0;   //超过帧动画总数从第0帧开始   if (nowFram >= tex.Length)   {    nowFram = 0;   }  } }}

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
