C语言手写植物大战僵尸

创建主场景

#include<stdio.h>
#include<graphics.h>

#define WIN_WIDTH 900
#define WIN_HEIGHT 600

IMAGE imgBg;

//游戏初始化
void gameInit() {
	loadimage(&imgBg, "res/bg.jpg");

	initgraph(WIN_WIDTH, WIN_HEIGHT);
}

//更新窗口
void updateWindow() {
	putimage(0, 0, &imgBg);
}

int main(void) {
	//游戏初始化
	gameInit();

	//更新窗口
	updateWindow();

	system("pause");
	return 0;
}

实现植物卡牌

#include "tools.h"

//#define ZHI_WU_CUNT 3

enum { WAN_DOU, XIANG_RI_KUI, ZHI_WU_COUNT };

IMAGE imgBar;
IMAGE imgCards[ZHI_WU_COUNT];

void gameInit() {
	loadimage(&imgBar, "res/bar.png");

	//初始化植物卡牌
	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);
	}
}

void updateWindow() {
	//putimage(250, 0, &imgBar); //有黑边
	putimagePNG(250, 0, &imgBar);

	for (int i = 0; i < ZHI_WU_COUNT; i++) {
		int x = 338 + i * 65;
		int y = 6;
		putimage(x, y, &imgCards[i]);
	}
}

实现植物的选择和拖动

IMAGE* imgZhiWu[ZHI_WU_COUNT][20];

int curX, curY; //当前选中的植物，在移动过程中的位置
int curZhiWu; //0:没有选中，1:选择了第一种植物 etc.

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

void gameInit() {
	memset(imgZhiWu, 0, sizeof(imgZhiWu));

	//初始化植物卡牌
	char name[64];
	for (int i = 0; i < ZHI_WU_COUNT; i++) {
		for (int j = 0; j < 20; j++) {
			sprintf_s(name, sizeof(name), "res/zhiwu/%d/%d.png", i, j + 1);
			//先判断这个文件是否存在
			if (fileExist(name)) {
				imgZhiWu[i][j] = new IMAGE;
				loadimage(imgZhiWu[i][j], name);
			}
			else {
				break;
			}
		}
	}

	curZhiWu = 0;
	//创建游戏的图形窗口
	initgraph(WIN_WIDTH, WIN_HEIGHT, 1); //加一个参数1，保留后台界面，方便调试
}

void updateWindow() {
	BeginBatchDraw(); //开始缓冲（先打印到内存中）

	//渲染 拖动过程中的植物
	if (curZhiWu > 0) {
		IMAGE* img = imgZhiWu[curZhiWu - 1][0];
		putimagePNG(curX - img->getwidth() / 2, curY - img->getheight() / 2, img);
	}

	EndBatchDraw(); //结束双缓冲（再一次性打印到窗口）
}
void userClick() {
	ExMessage msg;
	static int status = 0;//状态变量（先点击再拖动）
	if (peekmessage(&msg)) {
		if (msg.message == WM_LBUTTONDOWN) { //左击按下
			if (msg.x > 338 && msg.x < 338 + 65 * ZHI_WU_COUNT && msg.y < 96) {
				int index = (msg.x - 338) / 65; //选择卡牌序号
				printf("%d\n", index);
				status = 1; //可以拖动
				curZhiWu = index + 1;
			}
		}
		else if (msg.message == WM_MOUSEMOVE && status == 1) { //鼠标移动
			curX = msg.x;
			curY = msg.y;

		}
		else if (msg.message == WM_LBUTTONUP) { //左键抬起

		}
	}

}
int main(void) {
	gameInit();

	while (1) {
		userClick();

		updateWindow();
	}

	system("pause");
	return 0;
}

实现植物的种植

struct zhiwu {
	int type;		//0:没有选中，1:第一种植物	etc.				
	int frameIndex; //序列帧的序号
};

struct zhiwu map[3][9];

void gameInit() {
	memset(map, 0, sizeof(map));
}

void updateWindow() {
	for (int i = 0; i < 3; i++) {
		for (int j = 0; j < 9; j++) {
			if (map[i][j].type > 0) {
				int x = 256 + j * 81;
				int y = 179 + i * 102 + 14;
				int zhiWuType = map[i][j].type - 1;
				int index = map[i][j].frameIndex;
				putimagePNG(x, y, imgZhiWu[zhiWuType][index]);
			}
		}
	}
}
void userClick() {
	if (peekmessage(&msg)) {
		else if (msg.message == WM_LBUTTONUP) { //左键抬起
			if (msg.x > 256 && msg.y > 179 && msg.y < 489) {
				int row = (msg.y - 179) / 102;
				int col = (msg.x - 256) / 81;
				//printf("%d, %d\n", row, col);
				if (map[row][col].type == 0) {
					map[row][col].type = curZhiWu;
					map[row][col].frameIndex = 0;
				}
			}
			curZhiWu = 0;
			status = 0;
		}
	}
}

实现植物的摇摆

//更新游戏相关数据
void updateGame() {
	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;
				}
			}
		}
	}
}

int main(void) {
	gameInit();
	while (1) {
		userClick();

		updateWindow();
		updateGame(); //更新游戏相关数据

		Sleep(10);//帧等待
	}

	system("pause");
	return 0;
}

优化游戏循环和游戏渲染循序

void updateWindow() {
	BeginBatchDraw(); //开始缓冲

	//渲染 拖动过程中的植物（放到了最后）
	if (curZhiWu > 0) {
		IMAGE* img = imgZhiWu[curZhiWu - 1][0];
		putimagePNG(curX - img->getwidth() / 2, curY - img->getheight() / 2, img);
	}

	EndBatchDraw(); //结束双缓冲
}

int main(void) {
	gameInit();
	int timer = 0;
	bool flag = true;
	while (1) {
		userClick();
		timer += getDelay();
		if (timer > 20) {
			flag = true;
			timer = 0;
		}

		if (flag) {
			flag = false;
			updateWindow();
			updateGame();
		}
	}

	system("pause");
	return 0;
}

制作启动菜单

void startUI() { //启动菜单
	IMAGE imgBg,imgMenu1,imgMenu2;
	loadimage(&imgBg, "res/menu.png");
	loadimage(&imgMenu1, "res/menu1.png");
	loadimage(&imgMenu2, "res/menu2.png");

	int flag = 0;
	while (1) {
		BeginBatchDraw();
		putimage(0, 0, &imgBg);
		putimagePNG(474, 75, flag ? &imgMenu2: &imgMenu1);

		ExMessage msg;
		if (peekmessage(&msg)) {
			if (msg.message == WM_LBUTTONDOWN&&
					msg.x>474&&msg.x<474+300&&
					msg.y>75&&msg.y<75+140){
				flag = 1;
				//EndBatchDraw();
			}
			else if (msg.message == WM_LBUTTONUP&&flag) {
				return;
			}
		}
		EndBatchDraw();
	}
}

int main(void) {
	gameInit();

	startUI();

	int timer = 0;
	bool flag = true;
	while (1) {
		userClick();
		timer += getDelay();
		if (timer > 20) {
			flag = true;
			timer = 0;
		}

		if (flag) {
			flag = false;
			updateWindow();
			updateGame();
		}

		Sleep(10);
	}

	system("pause");
	return 0;
}

创建随机阳光

#include<time.h>

struct sunshineBall {
	int x, y; //阳光球在飘落过程中的坐标位置（x不变）
	int frameIndex; //当前显示的图片帧的序号
	int destY; //飘落的目标位置的y坐标
	bool used; //是否在使用
};

//阳光池
struct sunshineBall balls[10];
IMAGE imgSunshineBall[29];


void gameInit() {
	memset(balls, 0, sizeof(balls));
	for (int i = 0; i < 29; i++) {
		sprintf_s(name, sizeof(name), "res/sunshine/%d.png", i + 1);
		loadimage(&imgSunshineBall[i], name);
	}

	//配置随机种子
	srand(time(NULL));
}

void creatSunshine() {
	static int count = 0;
	static int fre = 400;
	count++;
	if (count >= fre) { //每fre帧创建一个阳光，fre随机改变
		fre = 200 + rand() % 200;
		count = 0;

		//从阳光池中取一个可以使用的
		int ballMax = sizeof(balls) / sizeof(balls[0]);

		int i;
		for (i = 0; i < ballMax && balls[i].used; i++);
		if (i >= ballMax) return;

		balls[i].used = true;
		balls[i].frameIndex = 0;
		balls[i].x = 260 + rand() % (900 - 260);
		balls[i].y = 60;
		balls[i].destY = 200 + (rand() % 4) * 90;
	}
}

void updateGame() {
	creatSunshine();
}

显示随机阳光

struct sunshineBall {
	int x, y; //阳光球在飘落过程中的坐标位置（x不变）
	int frameIndex; //当前显示的图片帧的序号
	int destY; //飘落的目标位置的y坐标
	bool used; //是否在使用
	int timer; //计时器
};

void updateWindow() {
	int ballMax = sizeof(balls) / sizeof(balls[0]);
	for (int i = 0; i < ballMax; i++) {
		if (balls[i].used) {
			IMAGE* img = &imgSunshineBall[balls[i].frameIndex];
			putimagePNG(balls[i].x, balls[i].y, img);
		}
	}
}
	
void creatSunshine() {
	if (count >= fre) {
		balls[i].timer = 0;
	}
}

void updateSunshine() {
	int ballMax = sizeof(balls) / sizeof(balls[0]);
	for (int i = 0; i < ballMax; i++) {
		if (balls[i].used) {
			balls[i].frameIndex = (balls[i].frameIndex + 1) % 29;
			if (balls[i].timer == 0) { //未到达地面
				balls[i].y += 2;
			}
			if (balls[i].y >= balls[i].destY) {
				//balls[i].used = false;
				balls[i].timer++;
				if (balls[i].timer > 100) { //掉到地面100帧之后
					balls[i].used = false;
				}
			}
		}
	}
}

void updateGame() {
	creatSunshine(); //创建阳光
	updateSunshine(); //更新阳光的状态
}

收集阳光、显示阳光值

#include<mmsystem.h>
#pragma comment(lib,"winmm.lib")

int sunshine; //总阳光值

void gameInit() {
	sunshine = 150;

	//设置字体
	LOGFONT f;
	gettextstyle(&f);                     // 获取当前字体设置
	f.lfHeight = 30;                      // 设置字体高度为 48
	f.lfWidth = 15;
	strcpy(f.lfFaceName, "Segoe UI Black"); 
	f.lfQuality = ANTIALIASED_QUALITY;    // 设置输出效果为抗锯齿  
	settextstyle(&f);                     // 设置字体样式
	setbkmode(TRANSPARENT);				  //背景模式透明
	setcolor(BLACK);					  //字体颜色
}

void updateWindow() {
	char scoreText[8];
	sprintf_s(scoreText, sizeof(scoreText), "%d", sunshine);
	outtextxy(276, 67, scoreText); //在指定位置输出文本--分数
}

void collectSunshine(ExMessage* msg) {
	int count = sizeof(balls) / sizeof(balls[0]);
	int w = imgSunshineBall[0].getwidth(); //阳光球宽度
	int h = imgSunshineBall[0].getheight();//阳光球高度
	for (int i = 0; i < count; i++) {
		if (balls[i].used) {
			int x = balls[i].x;
			int y = balls[i].y;
			if (msg->x > x && msg->x < x + w && msg->y > y && msg->y < y + h) {
				balls[i].used = false;
				sunshine += 25;
				mciSendString("play res/sunshine.mp3", 0, 0, 0); //添加音效
			}
		}
	}
}

void userClick() {
	ExMessage msg;
	static int status = 0;
	if (peekmessage(&msg)) {
		if (msg.message == WM_LBUTTONDOWN) { //左击按下
			if (msg.x > 338 && msg.x < 338 + 65 * ZHI_WU_COUNT && msg.y < 96) {

			}
			else {
				collectSunshine(&msg);
			}
		}
