C语言游戏实战（12）：植物大战僵尸（坤版）

前言：

本游戏使用C语言和easyx图形库编写，通过这个项目我们可以深度的掌握C语言的各种语言特性和高级开发技巧，以及锻炼我们独立的项目开发能力，

在开始编写代码之前，我们需要先了解一下游戏的基本规则和功能：

游戏界面：游戏界面是一个矩形区域，玩家可以在区域内进行植物的放置和铲除等操作。

僵尸：僵尸会从游戏界面的右侧向左测移动，靠近植物后会停下来吃植物。

植物：不同的植物有不同的功能，在这里我们可以将植物分为三大类：

1. 生产型植物（如太阳花）：这种植物的特点是在一定的时间生产出太阳，以增加太阳的产量。

2.发射型植物（如豌豆射手）：这种植物的特点是发射相应类型的子弹，对僵尸产生伤害和特定的效果。

3. 爆炸性植物（火爆辣椒）：这种植物的特点是对一定区域的所有僵尸产生高额伤害。（一次性植物）

接下来，我们将通过以下几个步骤来实现这个游戏：

初始化游戏界面。

实现僵尸的创建、僵尸的更新、僵尸吃植物的检测。

实现的植物的放置。

实现植物的功能：

对于生产型植物我们需要写出阳光的生产，以及阳光的收集操作。

对于发射型植物我们需要判断植物是否发射子弹，发射子弹后还需更新子弹、检测子弹与僵尸的碰撞。

对于爆炸型植物，我们需要判断僵尸是否在爆炸范围内，然后杀死在爆炸范围内的僵尸。

1. 初始化游戏界面

我们需要先将游戏地图、卡牌和卡牌槽绘制出来。可以利用windows自带的画图工具测出游戏地图的位置，从而将这些卡牌和卡牌槽放置到合适的位置。

//地图
putimage(-150, 0, &img);
//卡牌槽
putimagePNG(80, -10, &imgBar);	
//植物卡牌for (int i = 0; i < PLANT_COUNT + 2; i++){if(i==PLANT_COUNT)putimagePNG(163 + i * 65 + 8, -5, &imgCards[i]);elseputimagePNG(163 + i * 65, 0, &imgCards[i]);}

2.  放置植物

因为需要在这个9*5的草地区域内放置植物，所以我们得计算出每个草方块的位置。我利用画图软件测出每个草方块大约是长81、宽100个像素点。 第一个草方块距离游戏窗口大约101个像素点。

这样就可以得出每个草方块的位置：256 - 150 + col * 81;100 + row * 100 - 15； 

每个植物都有相似的特性，所以我们需要写一个放置植物信息的结构体。然后创建一个5*9的结构体数组，用来表示每个草方块上的植物。

enum {WAN_DOU, TAI_YANG, LA_JIAO, KUN_KUN, JIAN_GUO,HAN_BING_WAN_DOU, YING_TAO, SAN_TOU_WAN_DOU, PLANT_COUNT
};
struct plant
{int type;//植物类型int frameIndex;//植物动作帧//bool catched;//是否被吃int blood;//血量int shootTime;//植物子弹的射速int timer;//阳光生产的时间int x, y;//植物坐标bool shoot;//判断植物是否处于发射状态
};
struct plant map[5][9];

 在 Windows 编程中，我们可以利用下面的变量获取鼠标信息。

ExMessage msg;
msg.message

ExMessage msg;
static int status = 0;
if (peekmessage(&msg))//判断有没有消息
{if (msg.message == WM_LBUTTONDOWN)//左键按下{//鼠标是否在卡牌的位置按下if (msg.x > 163 && msg.x < 163 + 65 * (PLANT_COUNT+2) && msg.y < 96){//mciSendString("play res/audio/bleep.mp3 alias BGM4", NULL, NULL, NULL);PlaySound("res/audio/bleep.wav", NULL, SND_FILENAME | SND_ASYNC);//PlaySound("res/sunshine.wav", NULL, SND_FILENAME | SND_ASYNC);int index = (msg.x - 163) / 65;//坤坤/*	if (index + 1 == KUN_KUN && sunshine >= 100){curPlant = index + 1;status = 1;curX = msg.x;curY = msg.y;sunshine -= 100;}*/curPlant = index + 1;status = 1;curX = msg.x;curY = msg.y;}}else if (msg.message == WM_MOUSEMOVE && status == 1)//鼠标移动{curX = msg.x;curY = msg.y;}else if (msg.message == WM_LBUTTONUP)//鼠标放下{if (msg.x > 256 - 150 && msg.x < Wide - 70 && msg.y > 100 && msg.y < 590){int row = (msg.y - 100) / 102;int col = (msg.x - 256 + 150 ) / 81;if (map[row][col].type == 0 && curPlant != PLANT_COUNT + 1 && curPlant != PLANT_COUNT + 2){//printf("%d\n", map[col][row].type);map[row][col].type = curPlant;map[row][col].frameIndex = 0;if(curPlant!=0)PlaySound("res/audio/coffee.wav", NULL, SND_FILENAME | SND_ASYNC);if (curPlant == 5)map[row][col].blood = KUNKUN_BLOOD * 50;elsemap[row][col].blood = KUNKUN_BLOOD;map[row][col].shootTime = 0;map[row][col].shoot = false;map[row][col].x = 256 - 150 + col * 81;map[row][col].y = 100 + row * 100 - 15;}else if (map[row][col].type != 0 && curPlant == PLANT_COUNT + 1){PlaySound("res/audio/coffee.wav", NULL, SND_FILENAME | SND_ASYNC);map[row][col].type = 0;map[row][col].blood = 0;}}}else if (msg.message == WM_RBUTTONDOWN)//鼠标右键{curPlant = 0;status = 0;}

3. 僵尸

 3.1 创建僵尸

僵尸也是和植物一样需要创建一个结构体存放信息。然后创建一个结构体数组，作为一个僵尸池，当需要创建一个僵尸时，我们就从这个池里取一个未被使用的僵尸。

struct zm
{int x, y;//僵尸的坐标int frameIndex;//僵尸动作帧bool used;//僵尸是否被使用int speed;//僵尸每一次移动的位移int row;//僵尸所在行int blood;//僵尸血量bool dead;//僵尸是否死亡bool eating;//僵尸是否在吃植物bool boom;//僵尸是否被炸死int zmSpeed;//僵尸的移动快慢
};
struct zm zms[ZM_MAX];

//找一个可用的僵尸
int i;
for (i = 0; i < zmMax && zms[i].used && zms[i].dead == false; i++);

到一定的时间就创建一个僵尸。

void createZM()
{if (zmCount >= zmCount_max)return;static int zmFre = 500;static int count = 0;//控制僵尸的生成快慢count++;if (count > zmFre){count = 0;zmFre = 200;int i = 0;int zmMax = sizeof(zms) / sizeof(zms[0]);for (i = 0; i < zmMax && zms[i].used && zms[i].dead == false; i++);if (i < zmMax){memset(&zms[i], 0, sizeof(zms[i]));zms[i].used = true;zms[i].speed = 2;zms[i].row = rand() % 5;zms[i].y = 100 + (zms[i].row) * 100 + 70;zms[i].x = Wide;zms[i].blood = ORDINARY_ZM_BLOOD;zms[i].dead = false;zms[i].boom = false;zms[i].zmSpeed = 4;zmCount++;}}
}

3. 2 检测僵尸对植物的伤害检测

僵尸靠近植物就将僵尸置为吃东西的状态，减植物的血量，当植物的血量小于等于0时，就去除植物。

void checkZM2Zhiwu()
{char name[64];int zCount = sizeof(zms) / sizeof(zms[0]);for (int i = 0; i < zCount; i++){//killCount = 0;if (zms[i].dead)continue;//zms[i].chomptime = 0;int row = zms[i].row;for (int j = 0; j < 9; j++){//if (map[row][j].type == 0)continue;//int zhiwuX = 101 + j * 81;int x1 = zhiwuX;int x2 = zhiwuX + 81;int x3 = zms[i].x + 100;if (x3 >= x1 && x3 <= x2){if (map[row][j].blood <= 0 || (map[row][j].type == 0 && zms[i].eating != false)){map[row][j].blood = 0;map[row][j].type = 0;zms[i].eating = false;//zms[i].frameIndex = 0;zms[i].speed = 3;}else if (map[row][j].type != 0){//mciSendString("play ZM_BGM repeat", NULL, NULL, NULL);//mciSendString("play name repeat", NULL, 0, NULL);zms[i].eating = true;zms[i].speed = 0;if (map[row][j].type != 3 && map[row][j].type != 7)map[row][j].blood--;//zms[i].frameIndex = 0;}}else if (x3 > 830){zms[i].eating = false;zms[i].speed = 3;}}}
}

4. 植物子弹

4.1 发射子弹

当僵尸出现在游戏界面时，与该僵尸同一行的发射性植物就发射出子弹。

同样需要创建一个结构体存放子弹的信息，然后创建一个子弹池。

//子弹
struct bullet
{double x, y;//子弹的坐标bool used;//子弹是否被使用int row;//子弹所在行int speed;//子弹速度bool blast;//是否发生爆炸int frameIndex;//帧序号
};
//坤坤
struct bullet bullets[1000];

 以坤坤为例：

void shoot()
{int lines[5] = { 0 };int bulletMax = sizeof(bullets) / sizeof(bullets[0]);int zmCount = sizeof(zms) / sizeof(zms[0]);int dangerX = Wide - 80;for (int i = 0; i < zmCount; i++){if (zms[i].dead == false && zms[i].x < dangerX && zms[i].x>100){lines[zms[i].row] = 1;}}for (int i = 0; i < 5; i++){for (int j = 0; j < 9; j++){//坤坤if (map[i][j].type == KUN_KUN + 1 && lines[i]){map[i][j].shootTime++;if (map[i][j].shootTime > 20){map[i][j].shootTime = 0;//子弹池int k;for (k = 0; k < bulletMax && bullets[k].used; k++);if (k < bulletMax){map[i][j].frameIndex = 3;bullets[k].used = true;bullets[k].row = i;bullets[k].speed = 10;bullets[k].blast = false;bullets[k].frameIndex = 0;int zwX = 256 - 150 + j * 81;int zwY = 100 + i * 100 - 15;bullets[k].x = zwX + imgPlant[map[i][j].type - 1][0]->getwidth() - 10;bullets[k].y = zwY + 5;}}}}}
}

4. 2  更新子弹

不断的改变加子弹的横坐标，当子弹出游戏界面时，子弹就被置为未被使用。

以坤坤为例：

void updateBullets_kunkun()
{int countMax = sizeof(bullets) / sizeof(bullets[0]);for (int i = 0; i < countMax; i++){if (bullets[i].used){bullets[i].x += bullets[i].speed;if (bullets[i].x > Wide){bullets[i].used = false;}}}
}

 4.3 检测子弹对僵尸的伤害

当子弹靠近僵尸时减去僵尸的一定量血量，然后对僵尸造成一定的效果（例如，坤坤子弹的效果是击退僵尸，那么我们只需要更改僵尸的横坐标即可。），最后将子弹置为未被使用。

以坤坤为例：

void checkBullet2Zm_kunkun()
{int bCount = sizeof(bullets) / sizeof(bullets[0]);int zCount = sizeof(zms) / sizeof(zms[0]);for (int i = 0; i < bCount; i++){{for (int j = 0; j < zCount; 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 && bullets[i].used) {zms[j].blood -= 20;zms[j].x += 1;bullets[i].blast = true;bullets[i].speed = 0;//bullets[i].x = 0;if (zms[j].blood <= 0){killCount++;zms[j].dead = true;zms[j].speed = 0;zms[j].frameIndex = 0;}break;}}}}
}

 5. 爆炸性植物

爆炸性植物是一次性的，当植物的动作帧执行完最后一帧后植物就置为死亡，在爆炸范围内的僵尸也死亡。

以火爆辣椒为例：

void checkBoom2Zm()
{int zCount = sizeof(zms) / sizeof(zms[0]);for (int i = 0; i < 5; i++){for (int j = 0; j < 9; j++){//火爆辣椒else if (map[i][j].type == LA_JIAO + 1){if (map[i][j].frameIndex > 7){for (int k = 0; k < zCount; k++){if (zms[k].used == false)continue;if (zms[k].row == i && zms[k].x < Wide - 80 - 70 && zms[k].dead == false){killCount++;zms[k].boom = true;zms[k].dead = true;zms[k].speed = 0;zms[k].frameIndex = 0;zms[k].blood = 0;}}if (map[i][j].frameIndex > 14){map[i][j].type = 0;map[i][j].frameIndex = 0;}}}}}
}

6. 小推车

 创建存放小车信息的结构体数组，小推车一条路一辆共5辆，所以我们只需写一个大小为5的结构体数组即可。

//小推车
struct car
{bool move;//是否处于移动状态int x, y;//位置bool used;//是否被使用
};
struct car cars[5];

放置小推车 

	for (int i = 0; i < 5; i++){cars[i].x = 50;cars[i].y = 100 + i * 100 - 15;cars[i].used = true;cars[i].move = false;}

检测小推车对小车的伤害 

当僵尸的横坐标小于等于小推车最左端的坐标时，小车置为移动状态，处于小推车左边的僵尸死亡。

void checkcars2Zm()
{for (int i = 0; i < 5; i++){int carsX = cars[i].x + 70;for (int j = 0; j < ZM_MAX; j++){if (zms[j].used && zms[j].dead == false && zms[j].row == i){int zmX = zms[j].x + 80;if (carsX > zmX && cars[i].used){if (cars[i].move == false)cars[i].move = true;else{killCount++;zms[j].dead = true;zms[j].speed = 0;zms[j].frameIndex = 0;}}}}}
}

更新小推车的位置

当小车被置为移动时，小推车开始移动。

void updatecar()
{for (int i = 0; i < 5; i++){if (cars[i].move){cars[i].x += 20;}if (cars[i].x > Wide){cars[i].move = false;cars[i].used = false;}}
}
