这次的作业是二选一，我综合了自己的兴趣以及情况，我选择了做一个3D游戏来完成。在查阅了很多资料之后，我选择了Unity3d来学习，因为它自带强大的编辑器，易于我们这些新人上手，在学习了两个星期后，我决定做一个之前很火的flappy bird来练手，下面是具体完成的情况。
设计思路：利用U3D自带的物理碰撞引擎去检测碰撞事件，在每帧重画的时候去选择小鸟形态的切换，给小鸟的一个水平的速度，然后在场景上设置一个触发器，负责场景的延生，这样游戏就可以源源不断的进行下去。
主要代码如下:
using UnityEngine;
using System.Collections;
public class Bird : MonoBehaviour {
public float timer=0;
public int frameNumber= 10;// frame number one seconds
public int frameCount=0;// frame counter
public bool animation=false;// whether play the fly animation
public bool canJump=false;
void Start(){
//this.rigidbody.velocity = new Vector3(2,0,0);
}
// Update is called once per frame
void Update () {
//hard code here for test
// Vector3 vel = this.rigidbody.velocity;
// this.rigidbody.velocity = new Vector3(5,vel.y,vel.z);
// animation
if(GameManager._intance.GameState==GameManager.GAMESTATE_PLAYING){
timer+=Time.deltaTime;
if(timer>=1.0f/frameNumber){
frameCount++;
timer-=1.0f/frameNumber;
int frameIndex = frameCount%3;
// update material ‘s offset x
// how to set the property of(x offset) MainTex : Main Texture
this.renderer.material.SetTextureOffset("_MainTex",new Vector2(0.333333f*frameIndex,0));
//this.renderer.material.SetTextureScale("_MainText",new Vector2(1,1));
}
}
if(GameManager._intance.GameState==GameManager.GAMESTATE_PLAYING){
// control jump
if(Input.GetMouseButton(0) ){// left mouse button down
audio.Play();
Vector3 vel2 = this.rigidbody.velocity;
this.rigidbody.velocity = new Vector3(vel2.x,5,vel2.z);
}
}
}
public void getLife(){
rigidbody.useGravity=true;
this.rigidbody.velocity = new Vector3(2,0,0);
}
}
using UnityEngine;
using System.Collections;
public class GameManager : MonoBehaviour {
// define the state of the game
public static int GAMESTATE_MENU =0;//游戏菜单状态
public static int GAMESTATE_PLAYING =1;//游戏中状态 ...
public static int GAMESTATE_END =2;//游戏结束状态
public Transform firstBg;
public int score = 0;
public int GameState = GAMESTATE_MENU;
public static GameManager _intance;
private GameObject bird;
void Awake(){
_intance = this;
bird = GameObject.FindGameObjectWithTag("Player");
}
void Update(){
if(GameState==GameManager.GAMESTATE_MENU){
if(Input.GetMouseButtonDown(0)){
// transform state
GameState = GAMESTATE_PLAYING;
// set bird is playing
// 1.set gravity 2.add velocity of x
bird.SendMessage("getLife");
}
}
if (GameState == GameManager.GAMESTATE_END) {
GameMenu._instance.gameObject.SetActive(true);
GameMenu._instance.UpdateScore(score);
}
}
}
using UnityEngine;
using System.Collections;
public class MoveTrigger : MonoBehaviour {
public Transform currentBg;
public Pipe pipe1;
public Pipe pipe2;
public void OnTriggerEnter(Collider other){
print("OnTriggerEnter");
if(other.tag=="Player")
{
// move the bg to the front of first transform
//1. get the first transfrom
Transform firstBg= GameManager._intance.firstBg;
// 2. move
currentBg.position = new Vector3( firstBg.position.x+10,currentBg.position.y,currentBg.position.z);
GameManager._intance.firstBg = currentBg;
// new position for pipe
pipe1.RandomGeneratePosition();
pipe2.RandomGeneratePosition();
}
}
}
心得体会：
通过这次U3D的学习，我有机会去了解3d程序的基本概念以及开发过程，在学习的过程中，我遇到了很多问题，通过查阅资料与咨询他人将这些问题都一一解决。从此之后，我觉得自己对编程也抱有更大的热情，受益匪浅。
