游戏开始界面
游戏的初始登陆界面，是由数据库与弹窗口实例化的界面、数据库和qt弹窗的相关功能和具体实现代码我会在后续的博客中补上

游戏开始中转界面
登陆成功后将跳转到第二个界面，这个界面只是个普通的中转界面，可以点击back跳转回去，也可以点击“开始游戏”进入关卡选择
在这儿可以拓展添加一些类使该变的更加的优美
#include"start.h"#include<QPainter>#include<QMouseEvent>Start::Start(QWidget *parent):QWidget(parent){setFixedSize(1800,967);setGeometry(70,50,1800,967);this->setWindowIcon(QIcon(":/img/icon.png"));this->setWindowTitle("愤怒的小鸟");//界面跳转

choose->show();});//绑定当前界面 发射的start开始游戏的信号 给选择关卡界面choose 让它显示connect(choose,&choosepoint::choosesceneback,this,[&](){this->setGeometry(choose->geometry());this->show();});//绑定choose选择关卡界面 发射的choosesceneback返回信号 给当前界面 让它显示/*connect(choose, &choosepoint::choosesceneback, [=](){//绑定choose选择关卡界面 发射的choosesceneback返回信号 给当前界面 让它显示
choose->hide();
this->show();
});*/}voidStart::paintEvent(QPaintEvent *event){
QPainter p(this);
p.drawPixmap(0,0,1800,967,QPixmap(":/img/start.jpg"));
p.drawPixmap(1713,10,77,32,QPixmap(":/img/BackButton.png"));}voidStart::mousePressEvent(QMouseEvent *event){//点击密码的显示与隐藏if(event->pos().x()>760&& event->pos().x()<1040&& event->pos().y()>510&& event->pos().y()<640){
emit start();hide();//隐藏当前界面}if(event->pos().x()>1713&& event->pos().x()<1790&& event->pos().y()>10&& event->pos().y()<42){
emit back();hide();//隐藏当前界面}}
开始游戏后进入关卡选择场景，
再该场景中可以选择进入哪一个关卡游戏
在该场景中使用了一个用一位数构造出二维数组的算法，而且该场景中选择的游戏，会在选择后再构造，在退出游戏后摧毁该场景类，清理内存空间
#include"choosepoint.h"#include<QMenuBar>#include<QPainter>#include<QDebug>#include"mybushbutton.h"#include<QTimer>#include<QLabel>

backbtn->setParent(this);
backbtn->move(1713,10);//跳转到上一个界面connect(backbtn,&mybushbutton::clicked,[=](){QTimer::singleShot(300,this,[=](){
emit this->choosesceneback();//为了看到动画效果hide();});});int i;//跳转到关卡界面 创建选择关卡的按钮for( i =0; i <20; i++){

label->setText(QString::number(i+1));

label->setAlignment(Qt::AlignHCenter | Qt:: AlignVCenter);//设置鼠标穿透事件 51号
label->setAttribute(Qt::WA_TransparentForMouseEvents);}}//重写绘图事件void choosepoint::paintEvent(QPaintEvent *){
QPainter painter(this);
QPixmap pix;//加载图片
pix.load(":/img/choose.jpg");
painter.drawPixmap(0,0,this->width(),this->height(),pix);}
游戏场景中的猪类
猪死亡时的爆炸特效砍了，因为会出现一些bug，具体改的方法我想的是需要重新改下这个猪类的设计方案，至少不能这么构造
#include"pig.h"#include<QPainter>#include<QTimer>#include<QPixmap>
pig::pig(){setFixedSize(64,64);
mid_pos =newQPoint(32,32);}void pig::paintEvent(QPaintEvent *event){
QPainter p1(this);// if(isboom)// {// QPainter p(pp);// p.drawPixmap(0, 0, 64,64, QPixmap(":/img/boom.png"));// }// else
p1.drawPixmap(0,0,64,64,QPixmap(":/img/pig.png"));}void pig::boom( pig *p){
isboom =true;//pp = p;update();QTimer::singleShot(200,this,[=](){
p->hide();});}
障碍物类
记录障碍物的中心点，方便后续中碰撞做算法
#include"obstacles.h"#include<QPixmap>#include<QDebug>#include<QBitmap>#include<QPainter>#include<QTimer>ObstAcles::ObstAcles(QString normalImg){
ImagPath = normalImg;
pix =new QPixmap;bool ret = pix->load(normalImg);if(!ret){qDebug()<<"图片加载失败";return;}setFixedSize(pix->width(), pix->height());*pix = pix->scaled(pix->width(), pix->height());setMask( pix->mask());setMinimumHeight(pix->height());setMinimumWidth(pix->width());
mid_width = pix->width();
mid_height = pix->width();qDebug()<<"obsacles "<<"w "<< mid_width <<"h "<< mid_height;
mid_pos =newQPoint(pix->width()/2, pix->height()/2);//mid_pos = QPoint(pix->width() / 2, pix->height() / 2);}voidObstAcles::paintEvent(QPaintEvent *event){
QPainter p(this);
p.drawPixmap(0,0,*pix);}
鸟类
主要是对鸟的运动状态的算法，port槽函数中 传参分别是 x方向初速度、y方向初速度、空气阻力常数、重力加速度
让小鸟动起来的主要思想是，给一个信号触发定时器，让定时器超时检测的信号去触发这个槽，只有第一次的时候才会给当前速度赋值，其他状态都是当前速度的积分来提供运动轨迹。
#include"bird.h"#include<QPixmap>#include<QDebug>#include<QBitmap>#include<QPainter>#include<QTimer>

游戏场景物体的构建
目前只为前四关写了障碍物和猪的布局分布效果，在该类中，有小鸟对障碍物碰撞后小鸟运动轨迹改变的算法，在该类中碰撞穿模的bug是因为我是对单个方块分析的，在取模上可能有一些误差，总而言之就是算法问题，会出现穿模的bug，这个bug的触发几率也不是特别大。
