1.打开unity，新建一个2D场景
2.将所有素材拖进去
3.添加两根导管 作为鸟穿过的通道，给导管添加Box Collider和声音，复制同样的两份，添加脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class PipeCollision : MonoBehaviour {
private void OnCollisionEnter(Collision collision)
{
if(collision.gameObject.tag=="Player")
{
this.GetComponent<AudioSource>().Play();
SceneManager.LoadScene(0);
}
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
}
4.添加鸟的素材，设置rigidbody、Sphere Collider和鸟飞行时的声音，添加脚本控制鸟的运动
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Bird : MonoBehaviour {
public float timer;
public int frameCount = 0;
public int frameNumber = 10;
public float birdSpeed = 5.0f;
// Use this for initialization
void Start () {
this.GetComponent<Rigidbody>().velocity = new Vector3(birdSpeed, 0, 0);
}
// Update is called once per frame
void Update () {
timer += Time.deltaTime;
if(timer>=1.0f/frameNumber)
{
frameCount = (frameCount + 1) % 3;
timer = 0;
this.GetComponent<Renderer>().material.SetTextureOffset("_MainTex", new Vector2(0.3333f * frameCount, 0));
}
if(Input.GetMouseButton(0))
{
Vector3 vel = this.GetComponent<Rigidbody>().velocity;
this.GetComponent<Rigidbody>().velocity = new Vector3(3, 3, vel.z);
this.GetComponent<AudioSource>().Play();
}
}
}
5.新建一个空对象，设置当鸟撞到导管时发生的事情，添加一个Box Collider，添加脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveTrigger : MonoBehaviour {
public Transform currentBG;
public Pipe p1;
public Pipe p2;
private void OnTriggerEnter(Collider other)
{
if(other.gameObject.tag=="Player")
{
Transform firstBG = GameManager._instance.lastBG;
currentBG.position = new Vector3(firstBG.position.x + 10, currentBG.position.y, currentBG.position.z);
GameManager._instance.lastBG = currentBG;
p1.RandomPosition();
p2.RandomPosition();
}
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
}
6.相机跟着鸟运动，添加脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CameraFollow : MonoBehaviour {
public GameObject bird;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
Vector2 birdPosition = bird.transform.position;
float posY = birdPosition.y;
if(posY>2)
{
posY = 2;
}
else if(posY<-2)
{
posY = -2;
}
this.transform.position = new Vector3(birdPosition.x + 9f, birdPosition.y, transform.position.z);
}
}
7.添加一个脚本统计分数
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GameManager : MonoBehaviour {
public Transform lastBG;
public static GameManager _instance;
public int score = 0;
// Use this for initialization
private void Awake()
{
_instance = this;
}
void Start () {
}
// Update is called once per frame
void Update () {
}
}
