C语言游戏实战（12）：植物大战僵尸（坤版）

植物大战僵尸

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***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  
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 = 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  100 && msg.y  
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***亡bool eating;//僵尸是否在吃植物bool boom;//僵尸是否被炸***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  
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  
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 = x1 && x3 100){lines[zms[i].row] = 1;}}for (int i = 0; i  20){map[i][j].shootTime = 0;                    //子弹池int k;for (k = 0; k 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  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  x1 && x  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  
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***亡。
 
void checkcars2Zm(){for (int i = 0; i  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  Wide){cars[i].move = false;cars[i].used = false;}}}
