写好游戏的图像化界面的框架

c语言练手项目【编写天天酷跑游戏2.0】EASYX图形库的运用。代码开源,素材已打包,c语言,游戏,开源

由于easyX不支持透明图片的的贴图,所以我们要自己写一个透明贴图的函数这里给出3个

// 适用于 y <0 以及y>0的任何情况
void putimagePNG2(int x, int y, IMAGE* picture);
void putimagePNG2(int x, int y, int winWidth, IMAGE* picture);
void putimagePNG(int  picture_x, int picture_y, IMAGE* picture);

// 适用于 y <0 以及x<0的任何情况
void putimagePNG2(int x, int y, IMAGE* picture) {
    IMAGE imgTmp;
    if (y < 0) {
        SetWorkingImage(picture);
        getimage(&imgTmp, 0, -y,
            picture->getwidth(), picture->getheight() + y);
        SetWorkingImage();
        y = 0;
        picture = &imgTmp;
    }

    if (x < 0) {
        SetWorkingImage(picture);
        getimage(&imgTmp, -x, 0, picture->getwidth() + x, picture->getheight());
        SetWorkingImage();
        x = 0;
        picture = &imgTmp;
    }

    putimagePNG(x, y, picture);
}

// 适用于 y <0 以及y>0的任何情况
void putimagePNG2(int x, int y, int winWidth, IMAGE* picture) {
    IMAGE imgTmp;
    if (y < 0) {
        SetWorkingImage(picture);
        getimage(&imgTmp, 0, -y,
            picture->getwidth(), picture->getheight() + y);
        SetWorkingImage();
        y = 0;
        picture = &imgTmp;
    }

    if (x < 0) {
        SetWorkingImage(picture);
        getimage(&imgTmp, -x, 0, picture->getwidth() + x, picture->getheight());
        SetWorkingImage();
        x = 0;
        picture = &imgTmp;
    }
    else if (x >= winWidth) {
        return;
    }
    else if (x > winWidth - picture->getwidth()) {
        SetWorkingImage(picture);
        getimage(&imgTmp, 0, 0, winWidth - x, picture->getheight());
        SetWorkingImage();
        picture = &imgTmp;
    }

    putimagePNG(x, y, picture);
}


// 载入PNG图并去透明部分
void putimagePNG(int  picture_x, int picture_y, IMAGE* picture) //x为载入图片的X坐标,y为Y坐标
{
    DWORD* dst = GetImageBuffer();    // GetImageBuffer()函数,用于获取绘图设备的显存指针,EASYX自带
    DWORD* draw = GetImageBuffer();
    DWORD* src = GetImageBuffer(picture); //获取picture的显存指针
    int picture_width = picture->getwidth(); //获取picture的宽度,EASYX自带
    int picture_height = picture->getheight(); //获取picture的高度,EASYX自带
    int graphWidth = getwidth();       //获取绘图区的宽度,EASYX自带
    int graphHeight = getheight();     //获取绘图区的高度,EASYX自带
    int dstX = 0;    //在显存里像素的角标

    // 实现透明贴图 公式: Cp=αp*FP+(1-αp)*BP , 贝叶斯定理来进行点颜色的概率计算
    for (int iy = 0; iy < picture_height; iy++)
    {
        for (int ix = 0; ix < picture_width; ix++)
        {
            int srcX = ix + iy * picture_width; //在显存里像素的角标
            int sa = ((src[srcX] & 0xff000000) >> 24); //0xAArrggbb;AA是透明度
            int sr = ((src[srcX] & 0xff0000) >> 16); //获取RGB里的R
            int sg = ((src[srcX] & 0xff00) >> 8);   //G
            int sb = src[srcX] & 0xff;              //B
            if (ix >= 0 && ix <= graphWidth && iy >= 0 && iy <= graphHeight && dstX <= graphWidth * graphHeight)
            {
                dstX = (ix + picture_x) + (iy + picture_y) * graphWidth; //在显存里像素的角标
                int dr = ((dst[dstX] & 0xff0000) >> 16);
                int dg = ((dst[dstX] & 0xff00) >> 8);
                int db = dst[dstX] & 0xff;
                draw[dstX] = ((sr * sa / 255 + dr * (255 - sa) / 255) << 16)  //公式: Cp=αp*FP+(1-αp)*BP  ; αp=sa/255 , FP=sr , BP=dr
                    | ((sg * sa / 255 + dg * (255 - sa) / 255) << 8)         //αp=sa/255 , FP=sg , BP=dg
                    | (sb * sa / 255 + db * (255 - sa) / 255);              //αp=sa/255 , FP=sb , BP=db
            }
        }
    }
}



//定义相关的变量
IMAGE imgBgs[3]; // 背景图片
int bgX[3];  //背景图片的x坐标
int bgSpeed[3] = { 1, 2, 4 };//三重背景以不同速度行驶

三张背景图片需要载入

//直接在初始化中加载到内存
    char name[64];
    for (int i = 0; i < 3; i++) {
        // "res/bg001.png"    "res/bg002.png"     "res/bg003.png"   
        sprintf(name, "res/bg%03d.png", i + 1);
        loadimage(&imgBgs[i], name);

        bgX[i] = 0;
    }

注:这里的图片在main.cpp文件夹中的res文件夹下。

再在updateBg的函数中进行渲染;

  	putimagePNG2(bgX[0], 0, &imgBgs[0]);
    putimagePNG2(bgX[1], 119, &imgBgs[1]);
    putimagePNG2(bgX[2], 330, &imgBgs[2]);

编译如果遇到C4996错误只需要在项目属性c/c++中关掉SDL检查即可。

如果出现loadimage()的错误,可能是字符集的问题;只需要在项目属性-高级-字符集-使用多字节字符集即可

看一下执行结果。

如果不使用透明贴图函数

图片成功渲染,但是在实际的游戏中,背景是会移动的且遵守基本的物理。

接下来我们需要移动背景。远处的移动慢,中处更快,最近处看起来最快,所以速度可以取int bgSpeed[3] = { 1, 2, 4 };

void moveBg() {
    for (int i = 0; i < 3; i++) {
        bgX[i] -= bgSpeed[i];
        if (bgX[i] < -WIN_WIDTH) {
            bgX[i] = 0;
        }
    }

在main函数中载入死循环 这样背景就可以无休止的移动了

int main(void) {
    init();
    while (1) {
        BeginBatchDraw();
        updateBg();
        EndBatchDraw();
        moveBg();

        Sleep(30);
    }
//使用beginbatchdraw 和endbatchdraw进行优化渲染。
    
}

实现玩家的奔跑

IMAGE imgHeros[12];//玩家的帧图片
int heroX; //玩家的x坐标
int heroY; //玩家的y坐标
int heroIndex; //玩家奔跑的图片帧序号

c语言练手项目【编写天天酷跑游戏2.0】EASYX图形库的运用。代码开源,素材已打包,c语言,游戏,开源

初始化的时候也初始化玩家

    // 加载Hero奔跑的图片帧素材
    for (int i = 0; i < 12; i++) {
        // "res/hero1.png"  ... "res/hero12.png"
        sprintf(name, "res/hero%d.png", i + 1);
        loadimage(&imgHeros[i], name);
    }
// 设置玩家的初始位置
    heroX = WIN_WIDTH * 0.5 - imgHeros[0].getwidth() * 0.5;
    heroY = 345 - imgHeros[0].getheight();
    heroIndex = 0;

在Main函数中给hero贴图

   putimagePNG2(heroX, heroY, &imgHeros[heroIndex]);

实现人物的跳跃

初始化函数中

c语言练手项目【编写天天酷跑游戏2.0】EASYX图形库的运用。代码开源,素材已打包,c语言,游戏,开源

heroJump = false;
jumpHeightMax = 345 - imgHeros[0].getheight() - 120;
heroJumpOff = -4;
bool heroJump; //表示玩家正在跳跃
int jumpHeightMax;
int heroJumpOff;

int jump()
{
    // 实现跳跃
    if (heroJump) {
        if (heroY < jumpHeightMax) {
            heroJumpOff = 4;
        }

        heroY += heroJumpOff;

        if (heroY > 345 - imgHeros[0].getheight()) {
            heroJump = false;
            heroJumpOff = -4;
        }
    }
    else { //不跳跃
        heroIndex = (heroIndex + 1) % 12;
    }
}
void jump() {
    heroJump = true;
}

获取玩家的输入

// 处理用户按键的输入
void keyEvent() {
    char ch;

    if (_kbhit()) { //如果有按键按下,_kbhit()返回  true  
        ch = _getch();    // _getch()不需要按下回车即可直接读取
        if (ch == ' ') {
            jump();
        }
    } 
}

main()

int main(void) {
    init();
    while (1) {
        keyEvent();
        BeginBatchDraw();

        updateBg();
        putimagePNG2(heroX, heroY, &imgHeros[heroIndex]);
        EndBatchDraw();
        moveBg();
        HeroIndex();
        jump(heroJump);
        Sleep(15);
    }

    
}

优化帧等待

bool update;   //表示是否需要马上刷新画面

init()尾部

update = true;

void jump() {
    heroJump = true;
    update = true;
}
int getDelay() {
    static unsigned long long lastTime = 0;
    unsigned long long currentTime = GetTickCount();
    if (lastTime == 0) {
        lastTime = currentTime;
        return 0;
    }
    else {
        int ret = currentTime - lastTime;
        lastTime = currentTime;
        return ret;
    }
}

main函数主体

int main(void) {
    int timer = 0;
    init();
    while (1) {
        keyEvent();
      
        timer += getDelay();//10
        if (timer > 30) {
            timer = 0;
            update = true;
        }

        if (update)
        {
            update = false;
            BeginBatchDraw();
            updateBg();
            putimagePNG2(heroX, heroY, &imgHeros[heroIndex]);
            EndBatchDraw();
            moveBg();
            HeroIndex();
            jump(heroJump);
         

        } 
       
    }

    return 0;
}


随机出现小乌龟障碍

定义乌龟相关的变量

IMAGE imgTortoise; //小乌龟
int torToiseX; //小乌龟的水平坐标
int torToiseY; //小乌龟的垂直坐标
bool torToiseExist; //当前窗口是否有小乌龟

在init()函数中,初始化乌龟

    // 加载小乌龟素材
    loadimage(&imgTortoise, "res/t1.png");
    torToiseExist = false;
    torToiseY = 345 - imgTortoise.getheight() + 5;

定义一个函数创建小乌龟

void creatTortoise() {
    // 创建小乌龟
    static int frameCount = 0;
    static int torToiseFre = 100;
    frameCount++;
    if (frameCount > torToiseFre) {
        frameCount = 0;
        if (!torToiseExist) {
            torToiseExist = true;
            torToiseX = WIN_WIDTH;
            torToiseFre = 200 + rand() % 300;
        }
    }

    if (torToiseExist) {
        torToiseX -= bgSpeed[2];
        if (torToiseX < -imgTortoise.getwidth()) {
            torToiseExist = false;
        }
    }
}


创建函数对乌龟进行渲染

void updateEnemy() {
    // 渲染小乌龟
    if (torToiseExist) {
        putimagePNG2(torToiseX, torToiseY, WIN_WIDTH, &imgTortoise);
    }
}

再把creattortorise

c语言练手项目【编写天天酷跑游戏2.0】EASYX图形库的运用。代码开源,素材已打包,c语言,游戏,开源

在main函数中调用if语句中

    update = false;
            BeginBatchDraw();
            updateBg();
            putimagePNG2(heroX, heroY, &imgHeros[heroIndex]);
            updateEnemy();
            EndBatchDraw();
            moveBg();
            HeroIndex();
            creatTortoise();
            jump(heroJump);
          

使用结构体优化障碍

添加头文件\#include <vector>

#define OBSTACLE_COUNT 10
typedef enum {
    TORTOISE, //乌龟  0
    LION, //狮子 1
    OBSTACLE_TYPE_COUNT  // 2
} obstacle_type;

vector<vector<IMAGE>>obstacleImgs; //存放所有障碍物的各个图片

typedef struct obstacle {
    obstacle_type type; //障碍物的类型 
    int imgIndex; //当前显示的图片的序号
    int x, y; //障碍物的坐标
    int speed;
    int power; //杀伤力
    bool exist;
}obstacle_t;

使用结构体后,重新初始化游戏

obstacle_t obstacles[OBSTACLE_COUNT];

// 游戏的初始化
void init() {
	// 创建游戏窗口
	initgraph(WIN_WIDTH, WIN_HEIGHT);

	// 加载背景资源
	char name[64];
	for (int i = 0; i < 3; i++) {
		// "res/bg001.png"    "res/bg002.png"     "res/bg003.png"   
		sprintf(name, "res/bg%03d.png", i + 1);
		loadimage(&imgBgs[i], name);

		bgX[i] = 0;
	}

	// 加载Hero奔跑的图片帧素材
	for (int i = 0; i < 12; i++) {
		// "res/hero1.png"  ... "res/hero12.png"
		sprintf(name, "res/hero%d.png", i + 1);
		loadimage(&imgHeros[i], name);
	}

	// 设置玩家的初始位置
	heroX = WIN_WIDTH * 0.5 - imgHeros[0].getwidth() * 0.5;
	heroY = 345 - imgHeros[0].getheight();
	heroIndex = 0;

	heroJump = false;
	jumpHeightMax = 345 - imgHeros[0].getheight() - 120;
	heroJumpOff = -4;

	update = true;

 
	IMAGE imgTort;
	loadimage(&imgTort, "res/t1.png");
	vector<IMAGE> imgTortArray;
	imgTortArray.push_back(imgTort);
	obstacleImgs.push_back(imgTortArray);

	IMAGE imgLion;
	vector<IMAGE> imgLionArray;
	for (int i = 0; i < 6; i++) {
		sprintf(name, "res/p%d.png", i + 1);
		loadimage(&imgLion, name);
		imgLionArray.push_back(imgLion);
	}
	obstacleImgs.push_back(imgLionArray);

	// 初始化障碍物池
	for (int i = 0; i < OBSTACLE_COUNT; i++) {
		obstacles[i].exist = false;
	}
}

创建函数初始化障碍物(我们将用此函数创建所有的障碍物)

void createObstacle() {
    int i;
    for (i = 0; i < OBSTACLE_COUNT; i++) {
        if (obstacles[i].exist == false) {
            break;
        }
    }
    if (i >= OBSTACLE_COUNT) {
        return;
    }

    obstacles[i].exist = true;
    obstacles[i].imgIndex = 0;
    obstacles[i].type = (obstacle_type)(rand() % OBSTACLE_TYPE_COUNT);
    obstacles[i].x = WIN_WIDTH;
    obstacles[i].y = 345 + 5 - obstacleImgs[obstacles[i].type][0].getheight();
    if (obstacles[i].type == TORTOISE) {
        obstacles[i].speed = 0;
        obstacles[i].power = 5; //自己修改
    }
    else if (obstacles[i].type == LION) {
        obstacles[i].speed = 4;
        obstacles[i].power = 20;
    }
}

再写一个函数进行创建障碍物的数据计算

void createObstacleData() {
 
		static int frameCount = 0;
	static int enemyFre = 50;
	frameCount++;
	if (frameCount > enemyFre) {
		frameCount = 0;
		enemyFre = 50 + rand() % 50; // 50..99
		createObstacle();
	}

 

	// 更新所有障碍物的坐标
	for (int i = 0; i < OBSTACLE_COUNT; i++) {
		if (obstacles[i].exist) {
			obstacles[i].x -= obstacles[i].speed + bgSpeed[2];
			if (obstacles[i].x < -obstacleImgs[obstacles[i].type][0].getwidth() * 2) {
				obstacles[i].exist = false;
			}

			int len = obstacleImgs[obstacles[i].type].size();
			obstacles[i].imgIndex = (obstacles[i].imgIndex + 1) % len;
		}
	}
}

在对敌人初始化

void updateEnemy() {
	// 渲染小乌龟
	//if (torToiseExist) {
	//    putimagePNG2(torToiseX, torToiseY, WIN_WIDTH, &imgTortoise);
	//}
	for (int i = 0; i < OBSTACLE_COUNT; i++) {
		if (obstacles[i].exist) {
			putimagePNG2(obstacles[i].x, obstacles[i].y, WIN_WIDTH,
				&obstacleImgs[obstacles[i].type][obstacles[i].imgIndex]);
		}
	}
}

一下是main函数的主体

		if (update)
		{
			update = false;
			BeginBatchDraw();
			updateBg();
			putimagePNG2(heroX, heroY, &imgHeros[heroIndex]);
			updateEnemy();
			EndBatchDraw();
			updateEnemy();
			moveBg();
			HeroIndex();
			createObstacleData();
			jump(heroJump);
		}

实现下蹲技能

IMAGE imgHeroDown[2];
bool heroDown; //表示玩家是否处于下蹲状态

init()中对其初始化

// 初始化障碍物池
	for (int i = 0; i < OBSTACLE_COUNT; i++) {
		obstacles[i].exist = false;
	}
	// 加载下蹲素材
	loadimage(&imgHeroDown[0], "res/d1.png");
	loadimage(&imgHeroDown[1], "res/d2.png");
	heroDown = false;

我们写一个heroupdown函数集成up和down方便进行管理

void heroupdown()
{
	 // 实现跳跃
		if (heroJump) {
			if (heroY < jumpHeightMax) {
				heroJumpOff = 4;
			}

			heroY += heroJumpOff;

			if (heroY > 345 - imgHeros[0].getheight()) {
				heroJump = false;
				heroJumpOff = -4;
			}
		}
		else if (heroDown) {
			static int count = 0;
			int delays[2] = { 4, 10 };
			count++;
			if (count >= delays[heroIndex]) {
				count = 0;
				heroIndex++;
				if (heroIndex >= 2) {
					heroIndex = 0;
					heroDown = false;
				}
			}
		}
		else { //不跳跃
			heroIndex = (heroIndex + 1) % 12;
		}
}
 
void down() {
	update = true;
	heroDown = true;
	heroIndex = 0;
}

在接受键盘进行响应

void keyEvent() {
	char ch;

	if (_kbhit()) { //如果有按键按下,_kbhit()返回  true  
		ch = _getch();    // _getch()不需要按下回车即可直接读取
		if (ch == ' ') {
			jump();
		}
		else if (ch == 'a') {
			down();
		}
	}
}
void updateHero() {
    if (!heroDown) {
        putimagePNG2(heroX, heroY, &imgHeros[heroIndex]);
    }
    else {
        int y = 345 - imgHeroDown[heroIndex].getheight();
        putimagePNG2(heroX, y, &imgHeroDown[heroIndex]);
    }
    
}

main函数主体

int main(void) {
	int timer = 0;
	init();
	while (1) {
		keyEvent();

		timer += getDelay();//10
		if (timer > 20) {
			timer = 0;
			update = true;
		}

		if (update)
		{
