写代码前的准备工作 

 搭建项目环境easyx：

要想在我们的窗口实现图片交互

应该给编译器安装 easyx 图形库

这边我用图片展示详细的安装操作

（1）我们先在网页找到官网

（2）然后点击下载

（3）将 easyx 安装到目标编译器

（4）出现安装成功就代表可以使用了

接下来我们就可以写放心写代码啦！！！

导入游戏素材 ：

在当前项目的目录下创建文件夹，并把解压好的文件拷贝进去

 修改项目属性：

<1>点击项目找到项目属性

<2>将字符集改成多字符集

这里图片操作的时候需要

<3>将编译器对SDL的检查关掉

这里检查文件是否存在的时候需要

导入我们的辅助项目：

 游戏页面的实现：

void startUI() {mciSendString("play res/audio/bg.mp3", 0, 0, 0);IMAGE imgMenu, imgMenu1, imgMenu2;int	flag = 0;loadimage(&imgMenu, "res/menu.png");	//加载开始背景图loadimage(&imgMenu1, "res/menu1.png");loadimage(&imgMenu2, "res/menu2.png");while (1) {BeginBatchDraw();           //开始绘图putimage(0, 0, &imgMenu);	//渲染开始背景图到窗口上putimagePNG(474, 75, flag == 0 ? &imgMenu1 : &imgMenu2);ExMessage	msg;if (peekmessage(&msg)) {if (msg.message == WM_LBUTTONDOWN &&	//鼠标左键落下	msg.x > 474 && msg.x < 774 && msg.y>75 && msg.y < 215) {flag = 1;mciSendString("play res/audio/awooga.mp3", 0, 0, 0);}}else if (msg.message == WM_LBUTTONUP && flag == 1) {	//鼠标左键抬起mciSendString("close res/audio/bg.mp3", 0, 0, 0);EndBatchDraw();return;}EndBatchDraw();              //结束绘图}
}

双缓冲绘图：

BeginBatchDraw() - 开始双缓冲

EndBatchDraw()    - 结束双缓冲

双缓冲区：打印一个的同时显示另一个，不断重复这个过程，避免了屏幕闪耀问题

游戏的背景初始化： 

void gameInit() {//设置随机种子srand(time(NULL));//加载游戏背景图片loadimage(&imgBg, "res/bg.jpg");//加载状态栏loadimage(&imgBar, "res/bar5.png");killZmCount = 0;zmCount = 0;gameStatus = GOING;memset(imgZhiWu, 0, sizeof(imgZhiWu));	//给指针赋空值memset(map, 0, sizeof(map));         	//初始化地图数组memset(balls, 0, sizeof(balls));    	//初始化阳光池memset(zms, 0, sizeof(zms));	        //初始化僵尸池memset(bullets, 0, sizeof(bullets));	//初始化豌豆子弹池//加载植物卡牌char name[64];for (int i = 0; i < ZHI_WU_COUNT; i++) {//生成植物卡牌的文件名sprintf_s(name, sizeof(name), "res/Cards/card_%d.png", i + 1);loadimage(&imgCards[i], name);for (int j = 0; j < 20; j++) {	sprintf_s(name, sizeof(name), "res/zhiwu/%d/%d.png", i, j + 1);//判断文件读取是否存在if (fileExist(name)) {imgZhiWu[i][j] = new IMAGE;loadimage(imgZhiWu[i][j], name);}else {break;}}}//初始化选中植物curZhiWu = 0;//初始化阳光值sunShine = 50;//加载阳光for (int i = 0; i < 29; i++) {	 sprintf_s(name, sizeof(name), "res/sunshine/%d.png", i + 1);loadimage(&imgSunShineBall[i], name);}//加载僵尸图片for (int i = 0; i < 22; i++) {sprintf_s(name, sizeof(name), "res/zm/%d.png", i + 1);loadimage(&imgZm[i], name);}//加载僵尸死亡图片for (int i = 0; i < 20; i++) {sprintf_s(name, sizeof(name), "res/zm_dead/%d.png", i + 1);loadimage(&imgZmDead[i], name);}//加载僵尸吃植物图片for (int i = 0; i < 21; i++) {sprintf_s(name, sizeof(name), "res/zm_eat/%d.png", i + 1);loadimage(&imgZmEat[i], name);}//加载巡场僵尸图片for (int i = 0; i < 11; i++) {sprintf_s(name, sizeof(name), "res/zm_stand/%d.png", i + 1);loadimage(&imgZmStand[i], name);}//加载豌豆子弹图片loadimage(&imgBulletNormal, "res/bullets/bullet_normal.png");//加载豌豆子弹爆炸图片loadimage(&imgBulletBlast[3], "res/bullets/bullet_blast.png");for (int i = 0; i < 3; i++) {float	k = (i + 2) * 0.2;loadimage(&imgBulletBlast[i], "res/bullets/bullet_blast.png",imgBulletBlast[3].getwidth() * k, imgBulletBlast[3].getheight() * k, true);}//创建游戏窗口initgraph(WIN_WIDTH, WIN_HEIGHT);	//设置字体LOGFONT	f;gettextstyle(&f);f.lfHeight = 30;f.lfWeight = 15;strcpy(f.lfFaceName, "Segoe UI Black");	//设置字体效果f.lfQuality = ANTIALIASED_QUALITY;		//抗锯齿settextstyle(&f);setbkmode(TRANSPARENT);					//字体模式：背景透明setcolor(BLACK);						//字体颜色：黑色}

 判断读取文件是否存在：

bool fileExist(const char* name) {FILE* fp = fopen(name, "r");if (fp == NULL) {return false;}else {fclose(fp);return true;}
}

将图片显示在窗口上：

void updateWindow() {BeginBatchDraw();putimage(-112, 0, &imgBg);	    //加载背景板putimagePNG(255, 0, &imgBar);	//加载状态栏for (int i = 0; i < ZHI_WU_COUNT; i++) {	//加载植物卡牌int x = 343 + i * 65;int y = 6;putimagePNG(x, y, &imgCards[i]);}//在地图上加载植物for (int i = 0; i < 3; i++) {for (int j = 0; j < 9; j++) {if (map[i][j].type > 0) {int zhiWuType = map[i][j].type - 1;int index = map[i][j].frameIndex;putimagePNG(map[i][j].x, map[i][j].y, imgZhiWu[zhiWuType][index]);}}}//加载拖动的植物if (curZhiWu > 0) {IMAGE* img = imgZhiWu[curZhiWu - 1][0];putimagePNG(curX - img->getwidth() / 2, curY - img->getheight() / 2, img);}//加载阳光值char scoreText[8];sprintf_s(scoreText, sizeof(scoreText), "%d", sunShine);	//把阳光值转换成字符类型outtextxy(283, 67, scoreText);				//加载僵尸for (int i = 0; i < zmMax; i++) {if (zms[i].used) {IMAGE* img = NULL;if (zms[i].eating) {img = imgZmEat;}else if (zms[i].dead) {img = imgZmDead;}else {img = imgZm;}img += zms[i].frameIndex;putimagePNG(zms[i].x, zms[i].y - img->getheight(), img);}}//加载豌豆子弹for (int i = 0; i < bulletMax; i++) {if (bullets[i].used) {if (bullets[i].blast) {	//豌豆子弹碰撞渲染IMAGE* img = &imgBulletBlast[bullets[i].frameIndex];putimagePNG(bullets[i].x, bullets[i].y, img);FlushBatchDraw();}else {	 putimagePNG(bullets[i].x, bullets[i].y, &imgBulletNormal);}}}//加载阳光for (int i = 0; i < ballMax; i++) {if (balls[i].used ) {IMAGE* img = &imgSunShineBall[balls[i].frameIndex];putimagePNG(balls[i].pCur.x, balls[i].pCur.y, img);}}EndBatchDraw();
}

 游戏场景动作的实现：

void updateGame() {//更新植物动作for (int i = 0; i < 3; i++) {for (int j = 0; j < 9; j++) {if (map[i][j].type > 0) {map[i][j].frameIndex++;int	zhiWuType = map[i][j].type - 1;int	index = map[i][j].frameIndex;if (imgZhiWu[zhiWuType][index] == NULL) {map[i][j].frameIndex = 0;}}}}//创建僵尸createZm();//更新僵尸动作updateZm();//创建阳光createSunShine();//更新阳光动作updateSunShine();//创建豌豆子弹createBullets();	//更新豌豆子弹动作updateBullets();//豌豆子弹与僵尸碰撞collisionCheck();
}

}

<2>实现阳光旋转动作>:

}

<3>实现阳光收集操作>:

void createBullets() {int lines[3] = { 0 };int	dangerX = WIN_WIDTH - imgZm[0].getwidth() + 50;	//定义开始射击距离for (int i = 0; i < zmMax; i++) {if (zms[i].used && zms[i].x < dangerX) {lines[zms[i].row] = 1;	}}for (int i = 0; i < 3; i++) {	for (int j = 0; j < 9; j++) {if (lines[i] && map[i][j].type == 1) {	//有豌豆且僵尸走到打击范围map[i][j].shootTimer++;if (map[i][j].shootTimer > 20) {map[i][j].shootTimer = 0;int k;PlaySound("res/audio/shootpea1.wav", NULL, SND_FILENAME | SND_ASYNC);for (k = 0; k < bulletMax && bullets[k].used; k++);if (k >= bulletMax) return;bullets[k].used = true;		bullets[k].row = i;bullets[k].speed = 5;bullets[k].blast = false;bullets[k].frameIndex = 0;int zwX = 256 - 112 + j * 81;int zwY = 179 + i * 102 + 14;bullets[k].x = zwX + imgZhiWu[0][0]->getwidth() - 10;bullets[k].y = zwY + 5;lines[i] = 0;}}}}
}

<2>实现豌豆子弹的动作>:

void updateBullets() {for (int i = 0; i < bulletMax; i++) {if (bullets[i].used) {bullets[i].x += bullets[i].speed;if (bullets[i].x > WIN_WIDTH) {bullets[i].used = false;}//碰撞播放完就消失if (bullets[i].blast) {bullets[i].frameIndex++;if (bullets[i].frameIndex > 3) {bullets[i].used = false;}}}}
}

游戏中植物与僵尸碰撞的实现：

<1>豌豆子弹与僵尸的碰撞检测实现>:

void checkBullettoZm() {for (int i = 0; i < bulletMax; i++) {if (bullets[i].used == false || bullets[i].blast)continue;	//如果豌豆子弹没使用或者已经开始碰撞，就跳过for (int j = 0; j < zmMax; j++) {if (zms[j].used == false)continue;int x1 = zms[j].x + 80;int x2 = zms[j].x + 110;int x = bullets[i].x;if (zms[j].dead == false && bullets[i].row == zms[j].row && x > x1 && x < x2) {	//豌豆子弹与僵尸碰撞后PlaySound("res/audio/peacrush1.wav", NULL, SND_FILENAME | SND_ASYNC);zms[j].blood -= 10;bullets[i].blast = true;bullets[i].speed = 0;if (zms[j].blood <= 0) {zms[j].dead = true;zms[j].speed = 0;zms[j].frameIndex = 0;}break;}}}
}

<2>僵尸与植物的碰撞检测实现>:

void checkZmtoZhiWu() {for (int i = 0; i < zmMax; i++) {if (zms[i].dead)continue;int row = zms[i].row;for (int k = 0; k < 9; k++) {if (map[row][k].type == 0)continue;int zhiWuX = 256 - 112 + k * 81;	    //定义僵尸开吃范围int x1 = zhiWuX + 10;int x2 = zhiWuX + 60;int x3 = zms[i].x + 80;if (x3 > x1 && x3 < x2) {if (map[row][k].catched == true) {	//僵尸吃的过程中的一些配置map[row][k].deadTimer++;mciSendString("play res/audio/zmeat.mp3", 0, 0, 0);if (map[row][k].deadTimer > 100) {mciSendString("play res/audio/plantDead.mp3", 0, 0, 0);map[row][k].deadTimer = 0;map[row][k].type = 0;zms[i].eating = false;zms[i].frameIndex = 0;zms[i].speed = 1;}}else {map[row][k].catched = true;map[row][k].deadTimer = 0;zms[i].eating = true;zms[i].speed = 0;zms[i].frameIndex = 0;}}}}
}

游戏场景巡场的实现： 

void viewScence() {int xMin = WIN_WIDTH - imgBg.getwidth();vector2 points[9] = { {550,80},{530,160},{630,170},{530,200},{525,270},		{565,370},{605,340},{705,280},{690,340} };int index[9];for (int i = 0; i < 9; i++) {index[i] = rand() % 11;}int count = 0;for (int x = 0; x >= xMin; x -= 4) {BeginBatchDraw();putimage(x, 0, &imgBg);count++;for (int k = 0; k < 9; k++) {putimagePNG(points[k].x - xMin + x, points[k].y, &imgZmStand[index[k]]);if (count >= 10) {index[k] = (index[k] + 1) % 11;}}if (count >= 10)count = 0;EndBatchDraw();Sleep(5);}for (int i = 0; i < 100; i++) {BeginBatchDraw();putimage(xMin, 0, &imgBg);for (int j = 0; j < 9; j++) {putimagePNG(points[j].x, points[j].y, &imgZmStand[index[j]]);index[j] = (index[j] + 1) % 11;}EndBatchDraw();Sleep(20);}for (int x = xMin; x <= -112; x += 4) {	BeginBatchDraw();putimage(x, 0, &imgBg);count++;for (int k = 0; k < 9; k++) {putimagePNG(points[k].x - xMin + x, points[k].y, &imgZmStand[index[k]]);if (count >= 10) {index[k] = (index[k] + 1) % 11;}if (count >= 10)count = 0;}EndBatchDraw();Sleep(5);}
}

游戏中状态栏下滑实现 ：

void barsDown() {IMAGE imgMenu, imgDaiFu1;int height = imgBar.getheight();for (int y = -height; y <= 0; y++) {BeginBatchDraw();putimage(-112, 0, &imgBg);putimagePNG(250, y, &imgBar);for (int i = 0; i < ZHI_WU_COUNT; i++) {int x = 338 + i * 65;putimagePNG(x, 6 + y, &imgCards[i]);}EndBatchDraw();Sleep(9);}loadimage(&imgMenu, "res/Maculk.png");loadimage(&imgDaiFu1, "res/a.png");putimagePNG(180, 117, &imgMenu);putimagePNG(0, 100, &imgDaiFu1);mciSendString("play res/audio/crazydaveshort2.mp3", 0, 0, 0);Sleep(2000);mciSendString("play res/audio/crazydavelong1.mp3", 0, 0, 0);Sleep(3000);
}

 游戏输赢的判断：

bool checkOver() {BeginBatchDraw();bool ret = false;if (gameStatus == WIN) {Sleep(100);mciSendString("close res/audio/Mountains.mp3 ", 0, 0, 0);loadimage(0, "res/gameWin.png");mciSendString("play res/win.mp3", 0, 0, 0);ret = true;}else if (gameStatus == FAIL) {Sleep(100);mciSendString("close res/audio/Mountains.mp3 ", 0, 0, 0);loadimage(0, "res/gameFail.png");mciSendString("play res/lose.mp3", 0, 0, 0);ret = true;}EndBatchDraw();return ret;
}

用户的鼠标操作：

左键点击移动目标植物到指定位置

点击右键进行种植

void userClick() {static	int status = 0;ExMessage	msg;if (peekmessage(&msg)) {	                //判断用户是否有操作if (msg.message == WM_LBUTTONDOWN) {	//鼠标左键按下if (msg.x > 343 && msg.x < 343 + 65 * ZHI_WU_COUNT && msg.y < 96) {	int index = (msg.x - 343) / 65;//判断阳光值是否足够购买植物if (index == XIANG_RI_KUI) {if (sunShine >= 50) {status = 1;curZhiWu = index + 1;curX = msg.x;curY = msg.y;sunShine -= 50;}}else if (index == WAN_DAO) {if (sunShine >= 100) {status = 1;curZhiWu = index + 1;curX = msg.x;curY = msg.y;sunShine -= 100;}}else if (index == JIAN_GUO) {if (sunShine >= 50) {status = 1;curZhiWu = index + 1;curX = msg.x;curY = msg.y;sunShine -= 50;}}}else {	                          //收集阳光事件collectSunshine(&msg);}}else if (msg.message == WM_MOUSEMOVE && status == 1) {	//鼠标移动curX = msg.x;curY = msg.y;}else if (msg.message == WM_RBUTTONDOWN && status == 1) {	//鼠标右键按下种植if (msg.x > 256 - 112 && msg.x < 900 - 30 && msg.y > 179 && msg.y < 489) {mciSendString("play res/audio/plantdown.mp3", 0, 0, 0);int	row = (msg.y - 179) / 102;	    //获取行int	col = (msg.x - 256 + 112) / 81;	//获取列if (map[row][col].type == 0) {map[row][col].type = curZhiWu;	//给鼠标当前行种下植物map[row][col].frameIndex = 0;	//渲染植物第一帧map[row][col].shootTimer = 0;	//初始化发射时间map[row][col].x = 256 - 112 + col * 81;	//植物坐标map[row][col].y = 179 + row * 102 + 14;}}//使植物释放消失curZhiWu = 0;status = 0;}}
}

 main主菜单：

int main(void) {gameInit();  	//游戏初始化startUI();	    //加载游戏开始界面viewScence();	//场景巡场mciSendString("play res/audio/Mountains.mp3", 0, 0, 0);barsDown();  	//状态栏下滑int timer = 0;bool flag = true;while (1){userClick();	        //获取用户点击事件timer += getDelay();	//获取间隔时间if (timer > 20) {	    //用来限制植物渲染时间timer = 0;flag = true;}if (flag) {flag = false;updateWindow();	        //更新游戏窗口updateGame();	        //更新动作if (checkOver())break;	//检查游戏是否结束}}system("pause");
