Fly bird birds making games using C language

Production ideas:

1. Birds descend one space every so often
2. Press the spacebar to jump the Birds
3. Obstacles (walls), there is a gap among the birds through obstacles
4. Birds will move to the side wall
5. Determine whether the bird hit the wall, the wall of death, did not hit continue
6. Infinite loop random wall

The original game:

the C produced the effect:

all the code:

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <windows.h>

int bird_x,bird_y;							//小鸟坐标
int fast;									//速度
int width,high;								//边框
int safe_up,safe_down,Up,Down,distance;		//安全区，上墙，下墙,距离原点的长度

void HideCursor()//隐藏光标，避免光标闪烁
{
	//关闭光标
	CONSOLE_CURSOR_INFO cci;    
	cci.bVisible = FALSE;    
	cci.dwSize = sizeof(cci);    
	HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);    
	SetConsoleCursorInfo(handle, &cci);
}

void makeNum()//随机制造墙和距离
{
	SYSTEMTIME sys;
	GetLocalTime(&sys);
	char tmp[64]={0};
	int nUp;
	sprintf(tmp,"%02d",sys.wSecond);
	nUp = atoi(tmp);//上限
	int nJL = nUp;//距离
	
	nUp = nUp%10;
	nJL = nJL%30;
	
	Up = nUp;
	safe_up = Up+1;
	safe_down = safe_up+3;
	Down = safe_down+1;
	distance = nJL;
}

void ready()//初始化

	bird_y = 5;
	width = 20;

}

void birdUpdate()//内部更新
{
	bird_y ++;
	distance --;
	if(distance <= 1 && (bird_y <= Up || bird_y >= Down))//撞到墙

				printf("*");
			else
				printf(" ");
		}
		printf("\n");
	}
}

void userUpdate() //用户输入所致的更新
{
	//printf("123");
	char chInput;
	if(kbhit())
	{

	}
}

int main()
