代码分析

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
代码设计如下

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

  1. #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
  2.     choose =new choosepoint;connect(this,&Start::start,this,[&](){
  3.         choose->setGeometry(this->geometry());
  4.                 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
  5.         choose->hide();
  6.         this->show();
  7.     });*/}voidStart::paintEvent(QPaintEvent *event){
  8.     QPainter p(this);
  9.     p.drawPixmap(0,0,1800,967,QPixmap(":/img/start.jpg"));
  10.     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){
  11.         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){
  12.         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

  1. #include"choosepoint.h"#include<QMenuBar>#include<QPainter>#include<QDebug>#include"mybushbutton.h"#include<QTimer>#include<QLabel>
  3. choosepoint::choosepoint(QWidget *parent):QMainWindow(parent){//选择关卡场景this->setFixedSize(1800,967);setGeometry(70,50,1800,967);this->setWindowIcon(QIcon(":/img/icon.png"));this->setWindowTitle("关卡场景");//返回按钮
  4.     mybushbutton * backbtn =newmybushbutton(":/img/BackButton.png",":/img/BackButtonSelected.png");
  6.     backbtn->setParent(this);
  7.     backbtn->move(1713,10);//跳转到上一个界面connect(backbtn,&mybushbutton::clicked,[=](){QTimer::singleShot(300,this,[=](){
  8.             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++){
  9.         mybushbutton * menubtn =newmybushbutton(":/img/LevelIcon.png");
  11.         menubtn->setParent(this);
  12.         menubtn->move(560+ i %5*160,300+ i /5*130);//一维数构造二维数组connect(menubtn,&mybushbutton::clicked,[=](){this->hide();//隐藏当前界面//界面跳转
  13.                 shot =newslingshot(i +1);
  14.                 shot->setGeometry(this->geometry());
  15.                 shot->show();//设置游戏场景初始位置//监听返回connect(shot,&slingshot::back,this,[=](){this->setGeometry(shot->geometry());
  17.                 shot->deleteLater();this->show();});//});
  18.         QLabel * label =new QLabel;
  19.         label->setParent(this);
  20.         label->setFixedSize(menubtn->width(),menubtn->height());
  21.         label->setText(QString::number(i+1));
  22.         label->move(560+ i %5*160,300+ i /5*130);//设置label上的文字对齐方式
  23.         label->setAlignment(Qt::AlignHCenter | Qt:: AlignVCenter);//设置鼠标穿透事件  51号
  24.         label->setAttribute(Qt::WA_TransparentForMouseEvents);}}//重写绘图事件void choosepoint::paintEvent(QPaintEvent *){
  25.     QPainter painter(this);
  26.     QPixmap pix;//加载图片
  27.     pix.load(":/img/choose.jpg");
  28.     painter.drawPixmap(0,0,this->width(),this->height(),pix);}

在这里插入图片描述

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

  1. #include"pig.h"#include<QPainter>#include<QTimer>#include<QPixmap>
  3. pig::pig(){setFixedSize(64,64);
  4.     mid_pos =newQPoint(32,32);}void pig::paintEvent(QPaintEvent *event){
  6.      QPainter p1(this);//     if(isboom)//     {//         QPainter p(pp);//         p.drawPixmap(0, 0, 64,64, QPixmap(":/img/boom.png"));//     }//     else
  7.         p1.drawPixmap(0,0,64,64,QPixmap(":/img/pig.png"));}void pig::boom( pig *p){
  8.     isboom =true;//pp = p;update();QTimer::singleShot(200,this,[=](){
  9.          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

  1. #include"obstacles.h"#include<QPixmap>#include<QDebug>#include<QBitmap>#include<QPainter>#include<QTimer>ObstAcles::ObstAcles(QString normalImg){
  2.     ImagPath = normalImg;
  3.     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());
  5.     mid_width = pix->width();
  6.     mid_height = pix->width();qDebug()<<"obsacles "<<"w "<< mid_width <<"h "<< mid_height;
  8.     mid_pos =newQPoint(pix->width()/2, pix->height()/2);//mid_pos = QPoint(pix->width() / 2, pix->height() / 2);}voidObstAcles::paintEvent(QPaintEvent *event){
  9.     QPainter p(this);
  11.     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。

  1. #include"bird.h"#include<QPixmap>#include<QDebug>#include<QBitmap>#include<QPainter>#include<QTimer>
  3. bird::bird(QString normalImg){
  4.     ImagPath = normalImg;
  5.     pix =new QPixmap;bool ret = pix->load(normalImg);if(!ret){qDebug()<<"图片加载失败";return;}*pix = pix->scaled(pix->width()*0.08, pix->height()*0.08);setFixedSize(pix->width()*0.08, pix->height()*0.08);setMask( pix->mask());setMinimumHeight(pix->height());setMinimumWidth(pix->width());
  7.     mid_width = pix->width()*0.08;
  8.     mid_height = pix->height()*0.08;qDebug()<<"brid "<<"w "<< mid_width <<"h "<< mid_height;
  10.     mid_pos =newQPoint(pix->width()*0.08/2, pix->height()*0.08/2);//mid_pos = QPoint(pix->width() * 0.08 / 2, pix->height() * 0.08 / 2);

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。
