C语言实现植物大战僵尸(完整版）

实现这个游戏需要Easy_X

这个在我前面一篇C++之番外篇爱心代码有程序教你怎么下载，大家可自行查看

然后就是需要植物大战僵尸的素材和音乐，需要的可以在评论区

首先是main.cpp

}// 适用于 y <0 以及x<0的任何情况
void putimagePNG(int x, int y, IMAGE* picture) {IMAGE imgTmp, imgTmp2, imgTmp3;int winWidth = getwidth();int winHeight = getheight();if (y < 0) {SetWorkingImage(picture);getimage(&imgTmp, 0, -y,picture->getwidth(), picture->getheight() + y);SetWorkingImage();y = 0;picture = &imgTmp;}else if (y >= getheight() || x >= getwidth()) {return;}else if (y + picture->getheight() > winHeight) {SetWorkingImage(picture);getimage(&imgTmp, x, y, picture->getwidth(), winHeight - y);SetWorkingImage();picture = &imgTmp;}if (x < 0) {SetWorkingImage(picture);getimage(&imgTmp2, -x, 0, picture->getwidth() + x, picture->getheight());SetWorkingImage();x = 0;picture = &imgTmp2;}if (x > winWidth - picture->getwidth()) {SetWorkingImage(picture);getimage(&imgTmp3, 0, 0, winWidth - x, picture->getheight());SetWorkingImage();picture = &imgTmp3;}_putimagePNG(x, y, picture);
}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;}
}

然后是vector2.cpp

//头文件要求
#include <cmath>struct vector2
{vector2(int _x = 0, int _y = 0) :x(x), y(y){}vector2(int* data):x(data[0]),y(data[1]){}long long x, y;
};//加法
vector2 operator +(vector2 x, vector2 y) { return vector2(x.x + y.x, x.y + y.y ); 
}//减法
vector2 operator -(vector2 x, vector2 y) {return vector2(x.x - y.x, x.y - y.y);
}// 乘法
vector2 operator *(vector2 x, vector2 y) {return vector2(x.x * y.x - x.y * y.y, x.y * y.x + x.x * y.y);
}// 乘法
vector2 operator *(vector2 y, float x) {return vector2(x*y.x, x*y.y);
}vector2 operator *(float x, vector2 y) {return vector2(x * y.x, x * y.y);
}//叉积
long long cross(vector2 x, vector2 y) { return x.y * y.x - x.x * y.y; }//数量积 点积
long long dot(vector2 x, vector2 y) { return x.x * y.x + x.y * y.y; }//四舍五入除法
long long dv(long long a, long long b) {//注意重名！！！ return b < 0 ? dv(-a, -b): (a < 0 ? -dv(-a, b): (a + b / 2) / b);
}//模长平方
long long len(vector2 x) { return x.x * x.x + x.y * x.y; }//模长
long long dis(vector2 x) { return sqrt(x.x * x.x + x.y * x.y); }//向量除法
vector2 operator /(vector2 x, vector2 y) {long long l = len(y);return vector2(dv(dot(x, y), l), dv(cross(x, y), l));
}//向量膜
vector2 operator %(vector2 x, vector2 y) { return x - ((x / y) * y); }//向量GCD 
vector2 gcd(vector2 x, vector2 y) { return len(y) ? gcd(y, x % y) : x; }vector2 calcBezierPoint(float t, vector2 p0, vector2 p1, vector2 p2, vector2 p3) {float u = 1 - t;float tt = t * t;float uu = u * u;float uuu = uu * u;float ttt = tt * t;vector2 p = uuu * p0;p = p + 3 * uu * t * p1;p = p + 3 * u * tt * p2;p = p + ttt * p3;return p;
}

最后头文件tools.h

#pragma once
#include <graphics.h>void putimagePNG(int  picture_x, int picture_y, IMAGE* picture);
int getDelay();

vector2.h

#pragma once//头文件要求
#include <cmath>struct vector2 {vector2(int _x=0, int _y=0) :x(_x), y(_y) {}vector2(int* data) :x(data[0]), y(data[1]){}long long x, y;
};//加法
vector2 operator +(vector2 x, vector2 y);//减法
vector2 operator -(vector2 x, vector2 y);// 乘法
vector2 operator *(vector2 x, vector2 y);
vector2 operator *(vector2, float);
vector2 operator *(float, vector2);//叉积
long long cross(vector2 x, vector2 y);//数量积 点积
long long dot(vector2 x, vector2 y);//四舍五入除法
long long dv(long long a, long long b);//模长平方
long long len(vector2 x);//模长
long long dis(vector2 x);//向量除法
vector2 operator /(vector2 x, vector2 y);//向量膜
vector2 operator %(vector2 x, vector2 y);//向量GCD 
vector2 gcd(vector2 x, vector2 y);vector2 calcBezierPoint(float t, vector2 p0, vector2 p1, vector2 p2, vector2 p3);
