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。

  1. 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。

cpp 复制代码
//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。

cpp 复制代码
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。

cpp 复制代码
ExMessage msg;
msg.message
cpp 复制代码
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;
				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。

cpp 复制代码
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];
cpp 复制代码
//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。

cpp 复制代码
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。

cpp 复制代码
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。

cpp 复制代码
//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:

cpp 复制代码
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:

cpp 复制代码
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:

cpp 复制代码
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:

cpp 复制代码
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。

cpp 复制代码
//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

cpp 复制代码
	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。

cpp 复制代码
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。

cpp 复制代码
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;
		}
	}
}

源码:

test.cpp文件:

cpp 复制代码
#include"game.h"

//判断文件是否存在
bool fileExist(const char* name)
{
	FILE* pf = fopen(name, "r");
	if (pf == NULL)
	{
		return false;
	}
	else
	{
		fclose(pf);
		return true;
	}
}
