我尝试复刻贪吃蛇,但...... 有比较完美代码的,可以告诉我一下吗?

我的超级烂Code:

#include<bits/stdc++.h>
#include<windows.h>
using namespace std;
#define getkey(VK_NONAME) ((GetAsyncKeyState(VK_NONAME) & 0x8000)?1:0)
int ti(float a) {return ((int)(a*10+5))/10;}
void Setpos(float x,float y){COORD pos;pos.X=ti(y*4)/2;pos.Y=ti(x);SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),pos);}
void Color(int a){if(a==0) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_GREEN|FOREGROUND_BLUE);if(a==1) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN|FOREGROUND_BLUE);if(a==2) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN);if(a==3) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE);if(a==4) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED);if(a==5) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_GREEN);if(a==6) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_BLUE);if(a==7) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED|FOREGROUND_GREEN|FOREGROUND_BLUE);if(a==8) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED);if(a==9) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY|BACKGROUND_GREEN|BACKGROUND_BLUE);if(a==10) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY|BACKGROUND_RED|BACKGROUND_BLUE);if(a==11) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED|FOREGROUND_BLUE);if(a==12) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_RED|FOREGROUND_GREEN);if(a==13) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY);if(a==14) SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_GREEN|FOREGROUND_BLUE);}
