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]);
else
putimagePNG(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.messageExMessage 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;
else
map[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;
}
}

return true;
